Connecting to MySQL server on another PC in LAN - mysql

I have MySQL setup in a PC on my local network, how do I connect to it?
I also have MySQL installed on this computer (which I want to use to connect to the database).
I tried the following but it's not working:
mysql -u user -h 192.168.1.28:3306 -p password
ERROR 2005 (HY000): Unknown MySQL server host '192.168.1.28:3306' (0)
EDIT
Thanks for your help. Anyway, I connect without 3306 and I have another problem. MACBOOK is the name of my client computer.
mysql -u user -ppassword -h 192.168.1.28
ERROR 1045 (28000): Access denied for user 'user'#'MACBOOK' (using password: YES)
Thanks.

Users who can Install MySQL Workbench on MySQL Server Machine
If you use or have MySQL Workbench on the MySQL Server PC you can do this with just a few clicks. Recommend only for development environment.
Connect to MySQL Server
Find this option Users and Privileges from Navigator and click on it.
Select root user and change value for Limit to Hosts Matching to %.
The click Apply at the bottom.
This should enable root user to access MySQL Server from remote machine.

That was a very useful question! Since we need to run the application with a centralized database, we should give the privileges to that computer in LAN to access the particular database hosted in LAN PC. Here is the solution for that!
Go to MySQL server
Type the following code to grant access for other pc:
GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' IDENTIFIED BY 'root_password';
then type:
FLUSH PRIVILEGES;
Replace % with the IP you want to grant access for!

Since you have MySQL on your local computer, you do not need to bother with the IP address of the machine. Just use localhost:
mysql -u user -p
or
mysql -hlocalhost -u user -p
If you cannot login with this, you must find out what usernames (user#host) exist in the MySQL Server locally. Here is what you do:
Step 01) Startup MySQL so that no passwords are require no passwords and denies TCP/IP connections
service mysql restart --skip-grant-tables --skip-networking
Keep in mind that standard SQL for adding users, granting and
revoking privileges are disabled.
Step 02) Show users and hosts
select concat(''',user,'''#''',host,'''') userhost,password from mysql.user;
Step 03) Check your password to make sure it works
select user,host from mysql.user where password=password('YourMySQLPassword');
If your password produces no output for this query, you have a bad
password.
If your password produces output for this query, look at the users
and hosts. If your host value is '%', your should be able to connect
from anywhere. If your host is 'localhost', you should be able to
connect locally.
Make user you have 'root'#'localhost' defined.
Once you have done what is needed, just restart mysql normally
service mysql restart
If you are able to connect successfully on the macbook, run this
query:
SELECT USER(),CURRENT_USER();
USER() reports how you attempted to authenticate in MySQL
CURRENT_USER() reports how you were allowed to authenticate in
MySQL
Let us know what happens !!!
UPDATE 2012-02-13 20:47 EDT
Login to the remote server and repeat Step 1-3
See if any user allows remote access (i.e, host in mysql.user is '%'). If you do not, then add 'user'#'%' to mysql.user.

Follow a simple checklist:
Try pinging the machine ping 192.168.1.2
Ensure MySQL is running on the specified port 3306 i.e. it has not been modified.
Ensure that the other PC is not blocking inbound connections on that port. If it is, add a firewall exception to allow connections on port 3306 and allow inbound connections in general.
It would be nice if you could post the exact error as it is displayed when you attempt to make that connection.

mysql -u user -h 192.168.1.2 -p
This should be enough for connection to MySQL server.
Please, check the firewall of 192.168.1.2 if remote connection to MySQL server is enabled.

In Ubuntu Follow these steps:
Set bind-address at /etc/mysql/mysql.conf.d
Change bind-address = 127.0.0.1 to bind-address = 192.24.805.50 # your IP
Grant permission for the remote machine
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'#'[remoteip]' IDENTIFIED
BY 'anypassword' WITH GRANT OPTION;
Then try connect from remote machine
mysql -u root -h 192.24.805.50 -p

Connecting to any mysql database should be like this:
$mysql -h hostname -Pportnumber -u username -p (then enter)
Then it will ask for password. Note: Port number should be closer to -P or it will show error. Make sure you know what is your mysql port. Default is 3306 and is optional to specify the port in this case. If its anything else you need to mention port number with -P or else it will show error.
For example:
$mysql -h 10.20.40.5 -P3306 -u root -p (then enter)
Password:My_Db_Password

mysql>_
Note: If you are trying to connect a db at different location make sure you can ping to that server/computer.
$ping 10.20.40.5
It should return TTL with time you got back PONG.
If it says destination unreachable then you cannot connect to remote mysql no matter what.
In such case contact your Network Administrator or Check your cable connection to your computer till the end of your target computer. Or check if you got LAN/WAN/MAN or internet/intranet/extranet working.

actually you shouldn't specify port in the host name. Mysql has special option for port (if port differs from default)
kind of
mysql --host=192.168.1.2 --port=3306

You don't have to specify ':3306' after the IP, it's the default port for MySQL.
And if your MySQL server runs with another port than 3306, then you have to add '-P [port]' instead of adding it to the IP address.
The MySQL client won't recognize the syntax "host:port", you HAVE to use -P [port] instead.
And btw, if you use '-p password', it won't work and will ask you the password again. You have to stick the password to the -p : -ppassword. (still, it's a very bad habit, because anyone that could do a PS on your server could see the plain password...)

You should use this:
>mysql -u user -h 192.168.1.2 -P 3306 -ppassword
or this:
>mysql -u user -h 192.168.1.2 -ppassword
...because 3306 is a default port number.

Cyberpanel - how to enable remote sql connection with MYSQL Workbench [duplicate]

I have installed MySQL Community Edition 5.5 on my local machine and I want to allow remote connections so that I can connect from external source.
How can I do that?
That is allowed by default on MySQL.
What is disabled by default is remote root access. If you want to enable that, run this SQL command locally:
GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;
And then find the following line and comment it out in your my.cnf file, which usually lives on /etc/mysql/my.cnf on Unix/OSX systems. In some cases the location for the file is /etc/mysql/mysql.conf.d/mysqld.cnf).
If it's a Windows system, you can find it in the MySQL installation directory, usually something like C:\Program Files\MySQL\MySQL Server 5.5\ and the filename will be my.ini.
Change line
bind-address = 127.0.0.1
to
#bind-address = 127.0.0.1
And restart the MySQL server (Unix/OSX, and Windows) for the changes to take effect.
After doing all of above I still couldn't login as root remotely, but Telnetting to port 3306 confirmed that MySQL was accepting connections.
I started looking at the users in MySQL and noticed there were multiple root users with different passwords.
select user, host, password from mysql.user;
So in MySQL I set all the passwords for root again and I could finally log in remotely as root.
use mysql;
update user set password=PASSWORD('NEWPASSWORD') where User='root';
flush privileges;
Just a note from my experience, you can find configuration file under this path /etc/mysql/mysql.conf.d/mysqld.cnf.
(I struggled for some time to find this path)
In my case I was trying to connect to a remote mysql server on cent OS. After going through a lot of solutions (granting all privileges, removing ip bindings,enabling networking) problem was still not getting solved.
As it turned out, while looking into various solutions,I came across iptables, which made me realize mysql port 3306 was not accepting connections.
Here is a small note on how I checked and resolved this issue.
Checking if port is accepting connections:
telnet (mysql server ip) [portNo]
Adding ip table rule to allow connections on the port:
iptables -A INPUT -i eth0 -p tcp -m tcp --dport 3306 -j ACCEPT
Would not recommend this for production environment, but if your iptables are not configured properly, adding the rules might not still solve the issue. In that case following should be done:
service iptables stop
Hope this helps.
All process for remote login. Remote login is off by default.You need to open it manually for all ip..to give access all ip
GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' IDENTIFIED BY 'password';
Specific Ip
GRANT ALL PRIVILEGES ON *.* TO 'root'#'your_desire_ip' IDENTIFIED BY 'password';
then
flush privileges;
You can check your User Host & Password
SELECT host,user,authentication_string FROM mysql.user;
Now your duty is to change this
bind-address = 127.0.0.1
You can find this on
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf
if you not find this on there then try this
sudo nano /etc/mysql/my.cnf
comment in this
#bind-address = 127.0.0.1
Then restart Mysql
sudo service mysql restart
Now enjoy remote login
Please follow the below mentioned steps inorder to set the wildcard remote access for MySQL User.
(1) Open cmd.
(2) navigate to path C:\Program Files\MySQL\MySQL Server 5.X\bin and
run this command.
mysql -u root -p
(3) Enter the root password.
(4) Execute the following command to provide the permission.
GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'#'IP' IDENTIFIED BY
'PASSWORD';
USERNAME: Username you wish to connect to MySQL server.
IP: Public IP address from where you wish to allow access to MySQL
server.
PASSWORD: Password of the username used.
IP can be replaced with % to allow user to connect from any IP
address.
(5) Flush the previleges by following command and exit.
FLUSH PRIVILEGES;
exit;
or \q
I had to this challenge when working on a Java Project with MySQL server as the database.
Here's how I did it:
First, confirm that your MySQL server configuration to allow for remote connections. Use your preferred text editor to open the MySQL server configuration file:
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf
Scroll down to the bind-address line and ensure that is either commented out or replaced with 0.0.0.0 (to allow all remote connections) or replaced with Ip-Addresses that you want remote connections from.
Once you make the necessary changes, save and exit the configuration file. Apply the changes made to the MySQL config file by restarting the MySQL service:
sudo systemctl restart mysql
Next, log into the MySQL server console on the server it was installed:
mysql -u root -p
Enter your mysql user password
Check the hosts that the user you want has access to already. In my case the user is root:
SELECT host FROM mysql.user WHERE user = "root";
This gave me this output:
+-----------+
| host |
+-----------+
| localhost |
+-----------+
Next, I ran the command below to grant the root user remote access to the database named my_database:
USE my_database;
GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' IDENTIFIED BY 'my-password';
Note: % grants a user remote access from all hosts on a network. You can specify the Ip-Address of the individual hosts that you want to grant the user access from using the command - GRANT ALL PRIVILEGES ON *.* TO 'root'#'Ip-Address' IDENTIFIED BY 'my-password';
Afterwhich I checked the hosts that the user now has access to. In my case the user is root:
SELECT host FROM mysql.user WHERE user = "root";
This gave me this output:
+-----------+
| host |
+-----------+
| % |
| localhost |
+-----------+
Finally, you can try connecting to the MySQL server from another server using the command:
mysql -u username -h mysql-server-ip-address -p
Where u represents user, h represents mysql-server-ip-address and p represents password. So in my case it was:
mysql -u root -h 34.69.261.158 -p
Enter your mysql user password
You should get this output depending on your MySQL server version:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 4

That's all.
I hope this helps
Close comment at link /etc/mysql/mysql.conf.d/mysqld.cnf or /etc/mysql/my.cnf:
bind-address = 127.0.0.1 =>> #bind-address = 127.0.0.1
Change the hostname so that all machines can access it, run this SQL command locally:
UPDATE mysql.user SET Host='%' WHERE Host='localhost' AND User='root';
FLUSH PRIVILEGES;
Restart service:
sudo service mysql restart
Open port mysql:
sudo ufw allow 3306
If your MySQL server process is listening on 127.0.0.1 or ::1 only then you will not be able to connect remotely. If you have a bind-address setting in /etc/my.cnf this might be the source of the problem.
You will also have to add privileges for a non-localhost user as well.
If you installed MySQL from brew it really does only listen on the local interface by default. To fix that you need to edit /usr/local/etc/my.cnf and change the bind-address from 127.0.0.1 to *.
Then run brew services restart mysql.
Just F.Y.I
I pulled my hair out with this problem for hours.. finally I call my hosting provider and found that in my case using a cloud server that in the control panel for 1and1 they have a secondary firewall that you have to clone and add port 3306. Once added I got straight in..
For whom it needs it, check firewall port 3306 is open too, if your firewall service is running.
This blog How to setup a MySQL server on Local Area Network will be useful in setting up a MySQL from scratch
If mysqld has a bind address set to a loopback/local address (e.g. 127.0.0.1), the server will not be reachable from remote hosts, because a loopback interface cannot be reached from any remote host.
Set this option to 0.0.0.0 (:: for IPv4+6) to accept connections from any host, or to another externally-reachable address if you want to only allow connections on one interface.
Source
And for OS X people out there be aware that the bind-address parameter is typically set in the launchd plist and not in the my.ini file. So in my case, I removed <string>--bind-address=127.0.0.1</string> from /Library/LaunchDaemons/homebrew.mxcl.mariadb.plist.
Enabling remote root access can be dangerous. It would be preferable if you were to set up user accounts with more restrictive permissions. The following three steps should do it.
Ensure that the line starting with bind-address ... is at least commented out in your my.ini or my.cnf file. If it doesn't exist, move on.
You can find this file in C:\ProgramData\MySQL\MySQL Server 8.0 on Windows.
Afterwards, check that the user account you are establishing the connection with does not have localhost in the Limit to Hosts Matching field. While it isn't recommended, you can instead put % in that field for testing purposes. You can do this by opening a local connection to the server with MySQL Workbench, then going to Server>Users and Privileges from the menu bar and finding the user account you want to connect with.
The "Limit to Hosts Matching" field is what disallows you to connect non-locally. I.e. it limits the accepted connections to a pattern of IP addresses. Ideally, you should be accessing the MySQL server from a static IP address or subnet, so that you can be as restrictive as possible.
Obviously, your firewall should allow the MySQL Server application to communicate over the port you want. The physical networking equipment in between you and your server should allow communication on the port you want to connect with. (port 3306 typically)
MySQL 8 no longer allows you to create a user using the GRANT command. You need to create the user first.
CREATE USER 'root'#'%' IDENTIFIED BY 'PASSWORD';
GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
some times need to use name of pc on windows
first step) put in config file of mysql:
mysqld.cnf SET bind-address= 0.0.0.0
(to let recibe connections over tcp/ip)
second step) make user in mysql, table users, with name of pc on windows propierties, NOT ip
Check remote server grant permission to Wildcard access to port 3306:
sudo lsof -i -P -n | grep LISTEN
It should NOT be same like this:
mysqld 23083 mysql 21u IPv4 145900142 0t0 TCP
127.0.0.1:3306 (LISTEN)
In this case, we need to update /etc/mysql/mysql.conf.d/mysqld.cnf or /etc/mysql/mariadb.conf.d/50-server.cnf with:
bind-address = 127.0.0.1 --> 0.0.0.0
And then restart mysql "sudo service mysql restart"
In order to test mySQL connection from a client:
nc -vz <host_address> 3306

I can connect to my remote database via command line but not from golang, although local db works fine with both [duplicate]

MySQL 5.1.31 running on Windows XP.
From the local MySQL server (192.168.233.142) I can connect as root as follows:
>mysql --host=192.168.233.142 --user=root --password=redacted
From a remote machine (192.168.233.163), I can see that the mysql port is open:
# telnet 192.168.233.142 3306
Trying 192.168.233.142...
Connected to 192.168.233.142 (192.168.233.142).
But when trying to connect to mysql from the remote machine, I receive:
# mysql --host=192.168.233.142 --user=root --password=redacted
ERROR 1045 (28000): Access denied for user 'root'#'192.168.233.163' (using password: YES)
I have only 2 entries in mysql.user:
Host User Password
--------------------------------------
localhost root *blahblahblah
% root [same as above]
What more do I need to do to enable remote access?
EDIT
As suggested by Paulo below, I tried replacing the mysql.user entry for % with an IP specific entry, so my user table now looks like this:
Host User Password
------------------------------------------
localhost root *blahblahblah
192.168.233.163 root [same as above]
I then restarted the machine, but the problem persists.
You have to put this as root:
GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'#'IP' IDENTIFIED BY 'PASSWORD' with grant option;
;
where IP is the IP you want to allow access, USERNAME is the user you use to connect, and PASSWORD is the relevant password.
If you want to allow access from any IP just put % instead of your IP
and then you only have to put
FLUSH PRIVILEGES;
Or restart mysql server and that's it.
I was getting the same error after granting remote access until I made this:
From /etc/mysql/my.cnf
In newer versions of mysql the location of the file is
/etc/mysql/mysql.conf.d/mysqld.cnf
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address = 127.0.0.1
(comment this line: bind-address = 127.0.0.1)
Then run service mysql restart.
By default in MySQL server remote access is disabled. The process to provide a remote access to user is.
Go to my sql bin folder or add it to PATH
Login to root by mysql -uroot -proot (or whatever the root password is.)
On success you will get mysql>
Provide grant access all for that user.
GRANT ALL PRIVILEGES ON *.* TO 'username'#'IP' IDENTIFIED BY 'password';
Here IP is IP address for which you want to allow remote access, if we put % any IP address can access remotely.
Example:
C:\Users\UserName> cd C:\Program Files (x86)\MySQL\MySQL Server 5.0\bin
C:\Program Files (x86)\MySQL\MySQL Server 5.0\bin>mysql -uroot -proot
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' IDENTIFIED BY 'root';
Query OK, 0 rows affected (0.27 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.25 sec)
This for a other user.
mysql> GRANT ALL PRIVILEGES ON *.* TO 'testUser'#'%' IDENTIFIED BY 'testUser';
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
Hope this will help
Paulo's help lead me to the solution. It was a combination of the following:
the password contained a dollar sign
I was trying to connect from a Linux shell
The bash shell treats the dollar sign as a special character for expansion to an environment variable, so we need to escape it with a backslash. Incidentally, we don't have to do this in the case where the dollar sign is the final character of the password.
As an example, if your password is "pas$word", from Linux bash we must connect as follows:
# mysql --host=192.168.233.142 --user=root --password=pas\$word
Do you have a firewall ? make sure that port 3306 is open.
On windows , by default mysql root account is created that is permitted to have access from localhost only unless you have selected the option to enable access from remote machines during installation .
creating or update the desired user with '%' as hostname .
example :
CREATE USER 'krish'#'%' IDENTIFIED BY 'password';
Try to flush privileges again.
Try to restart server to reload grants.
Try create a user with host "192.168.233.163". "%" appears to not allow all (it's weird)

telnet (mysql server ip) [portNo]
Adding ip table rule to allow connections on the port:
iptables -A INPUT -i eth0 -p tcp -m tcp --dport 3306 -j ACCEPT
Would not recommend this for production environment, but if your iptables are not configured properly, adding the rules might not still solve the issue. In that case following should be done:
service iptables stop
Hope this helps.
if you are using dynamic ip just grant access to 192.168.2.% so now you dont have to worry about granting access to your ip address every time.
I was struggling with remote login to MYSQL for my Amazon EC2 Linux instance. Found the solution was to make sure my security group included an inbound rule for MySQL port 3306 to include my IP address (or 0.0.0.0/0 for anywhere). Immediately could connect remotely as soon as I added this rule.
MySQL ODBC 3.51 Driver is that special characters in the password aren't handled.
"Warning – You might have a serious headache with MySQL ODBC 3.51 if the password in your GRANT command contains special characters, such as ! # # $ % ^ ?. MySQL ODBC 3.51 ODBC Driver does not support these special characters in the password box. The only error message you would receive is “Access denied” (using password: YES)" - from http://www.plaintutorials.com/install-and-create-mysql-odbc-connector-on-windows-7/
The user/host combination may have been created without password.
I was assuming that when adding a new host for an existing user (using a GUI app), the existing password would also be used for the new user/host combination.
I could log in with
mysql -u username -p PASSWORD
locally, but not from IPADDRESS with
mysql -u --host=HOST -p PASSWORD
(I could actually log in from IPADDRESS without using a password)
mysql -u --host=HOST
Setting the password allowed access:
set password for '<USER>'#'<IPADDRESS>' = '<PASSWORD>';
New location for mysql config file is
/etc/mysql/mysql.conf.d/mysqld.cnf
My case is absolutely simple.
You may have this problem in case if you type in WRONG password. No create user is needed (user already existed), no other permissions. Basically make sure that the password is correct. So make double-sure the password is correct

MySQL Host '::1' or '127.0.0.1' is not allowed to connect to this MySQL server

I have a strange issue on a web server (Windows Server 2012) with MySQL 5.7.16.
I can't connect anymore to mysql server, I don't know why.
If I type mysql -uroot -ppassword appear an error
ERROR 1130 <HY000>: Host '::1' is not allowed to connect to this MySQL server or
ERROR 1130 <HY000>: Host '127.0.0.1' is not allowed to connect to this MySQL server
I tried to use another user with all privileges and I've seen that in host there is only localhost (not 127.0.0.1 or ::1)
How can I login with root#localhost and not with root#127.0.0.1?
It's very frustrating...
Every account trying to use #127.0.0.1 or #::1 but there exist only localhost in host and I can't change it.
If I type mysql -uroot -ppassword I see
ERROR 1130 <HY000>: Host '127.0.0.1' is not allowed to connect to this MySQL server
Same if I type mysql -uroot -ppassword -h localhost or anything else
Ok i Fixed...
I've comment "skip_name_resolve" in my.ini and everything is back to work.. i really don't know why because this record was in my.ini also yesterday..last week.. last month..
The variable skip_name_resolve gives better performance because the server does not try to resolve the names of the connecting clients or look for them every time in the host name cache (even localhost is resolved/searched), but the manual states that config also limits the #localhost connections. The solution is to copy the #localhost users with #127.0.0.1, like this:
CREATE USER 'root'#'127.0.0.1' IDENTIFIED BY 'root-password';
CREATE USER 'root'#'::1' IDENTIFIED BY 'root-password';
FLUSH PRIVILEGES;
where ::1 is localhost for IPv6 addressing. This way we keep the root and local accounts limited to the local server. Using '%' open the potential clients to the world, and we don't want that. Disabling skip_name_resolve also requires the server having an accesible and fast DNS resolver to minimize latency.
I noted that I can connect with a local phpmyadmin even if the user has #localhost; this is because phpmyadmin connects thru a local unix socket, a special type of file used to communicate between processes, and does not need networking.
EDIT: As #Francisco R noted, the new root users also should have full access to all databases by issuing the following commands:
GRANT ALL PRIVILEGES ON *.* TO 'root'#'127.0.0.1'
GRANT ALL PRIVILEGES ON *.* TO 'root'#'::1'
FLUSH PRIVILEGES
I had the same message after a fresh installation with the no-install zip and solved it as follows. Perhaps this could have been a solution for your problem too:
Stop the MySQL server or service.
Open a Command Prompt window with administrative rights and go to the bin folder in the MySQL install directory.
Start MySQL with skip-grants-table and don't forget your config file:
mysqld --defaults-file=[filename] --skip-grant-tables
Open another Command Prompt window and go to the bin folder again.
Now you can login:
mysql -u root -p
Show the users with:
SELECT user, host FROM mysql.user;
Verify there is one 'root' with host 'localhost'.
Change the host:
UPDATE mysql.user SET host='%' WHERE user='root';
Exit the mysql program and close the Command Prompt window.
Type Ctrl-C in the other Command Prompt window to stop the server, then close the Command Prompt Window.
Start MySQL as you normally would and verify that you can login.
Make sure that when you created the user you have specified % as the hostname, otherwise the user will only be able to connect from the localhost.
I came here looking for a solution using Local by flywheel for wordpress development to the same problem, BUT, in a linux machine.
Just if someone faces the same problem, the solution listed here works.
Just comment skip_name_resolve in the file conf/mysql/my.cnf.hbs under the file tree created by Local
Thanks!
Looks that you need to modify your hosts file. C:\Windows\System32\Drivers\etc\hosts
just add the line and save it, (to be able to edit and save you may need to open it as administrator)
127.0.0.1 localhost

Unable to setup remote connections MYSQL Ubuntu

I'm having trouble opening a up my MYSQL server to ALL remote connections. I have followed many online guides and appear to have something wrong. Perhaps SO could provide guidance? My server details are as follows:
Ubuntu 12.04 Server,
MYSQL Ver 14.14 Distrib 5.5.34, for debian-linux-gnu (x86_64) using readline 6.2
/etc/mysql/my.cnf: Other stuff too, but importantly the bind-address...
bind-address = 0.0.0.0
my.conf has the following permissions:
-rw-r--r-- 1 root root 3516 Jan 31 17:12 my.cnf
The server isn't blocked because:
telnet myDomain.com 3306
prompts for my native mysql password.
MYSQL Queries
CREATE USER 'myUser'#'%' IDENTIFIED BY 'myPASSWORD';
GRANT INSERT
ON db.table_v
TO 'myUser'#'%'
IDENTIFIED BY 'myPASSWORD';
FLUSH PRIVILEGES;
Permissions from show grants for 'myUser'#'%';
GRANT USAGE ON . TO 'myUser'#'%' IDENTIFIED BY PASSWORD '****************'
GRANT INSERT ON db.table_v TO 'myUser'#'%'
I also restarted my server
PROBLEM:
mysql -h myDomain.com -u myUser -p
Enter password:
ERROR 1045 (28000): Access denied for user 'myDomain'#'***MYIPADDRESS***' (using password: YES)
I am also not able to login locally with any user where the host is not specifically local, such as '%' or my home IP.
this is interesting if not typo:
Access denied for user 'myDomain'
are you trying to use your domain name as username? there should be myUser instead of myDomain cause you give remote permissions to myUser only.
also in:
mysql -h myDomain.com -u myUser -p
-h means the host where mysql server resides, not your user's current host. so trying anything other then "localhost" when you're locally trying to connect the database surely gives error cause you are trying to connect a database you are not intend to. suppose you are connected to mysql server locally and typed the above line; this command will try to connect the server at myDomain.com with the user myUser and password you provide. if the permissions you defined are where you run this command, you'll get that access denied error cause you are connecting to a different server.
I think the problem is the location of the .cnf file where you specify the bind-address attribute.
Most guides and tutorials say the file is /etc/mysql/my.cnf but after many tries I realized that the correct place was in mysqld.cnf file under mysqld profile.
Try to include the bind-address attribute there.
To check if this worked for you type "netstat -lt" and find if the local address of mysql process is 0.0.0.0:3306.
Then check again yor connection
You need also create local user account
CREATE USER 'myUser'#'localhost' IDENTIFIED BY 'myPASSWORD';
MySQL Manual | Adding users
I don't advise usage such unsecure statements as
GRANT ALL ON *.* TO 'myuser'#'%';
It creates superuser e.g. grants privileges to all databases for all operations.
May I ask why you need direct access to MySQL? MySQL should really only listen to localhost, but you can access easily using SSH.
If using Windows, Putty allows you to establish an SSH connection to the host, and then forward 3306 localhost traffic to your own computer.
Better still, programs like SQLyog allow SSH tunnel connections to MySQL which is how I usually connect (unless the servers are on a VPN).
Are you using this server for development or does it have a public IP address?
please post the result of
nmap ***MYIPADDRESS***
and
nmap localhost
and
nmap MyDomain
if you do not have nmap install it from apt, then I can help you more.
