I've two machine.
Machine 1 (Server) : MySQL Server installed on it.
Machine 2 (Client) : MySQL Server not installed on it.
I would like connect from Machine 2 (Client) to MySQL Server on Machine 1 (Server).
I did following command on Machine 1 (Server) to grant permission to all clients :
GRANT ALL ON *.* TO root#'%' IDENTIFIED BY '123456';
Well, I need to connect MySQL Server from Client.
I've write below command in cmd on Machine 2 (Client) :
mysql -h 192.168.0.1 -u root -p
192.168.0.1 on above line is Machine 1 (Server) IP.
But following error has occur :
`mysql` is not recognaized as an internal or external command, operable program or batch file.
I guess need to install something like mysql connector or something else on Machine 2 (Client), isn't it ?
You can use other tool with good looking GUI. For example: HeidiSQL.
Then, you need to enable remote access. If you use windows, there is nice wizard for you to enable remote access with a few clicks. The wizard is located it at MySQL Server 5.5\bin\MySQLInstanceConfig.exe. Then
Reconfigure Instance -> Next -> Standard Configuration -> Next -> Next. You will see this screen.
Tick on "Enable root access from remote machines". Or you can manually configure it to allow remote access from my.ini file. See this link for how to do it.
If having done above still does not allow you to connect to your MySQL. Please make sure that Firewall does not block MySQL port.
I can give you an idea to do it,
1st: You have to give permission from machine 1 for machine 2. You should edit httpd.conf file
Listen machine 2 ip (192.168.0.*)
2nd: You have to give permission for phpmyadmin by following code-
GRANT ALL PRIVILEGES ON Database.* to 'username'#'ip or url' IDENTIFIED by 'password';

I deploy a mysql service on my company remote develop CentOS machine, I'm sure the service is turn on, and it can be access from an other reomte linux machine.
However, I can't connect it from my own Windows PC. I tried mysql workbench client and HeidiSQL client, both failed. I can ping through the remote IP address. I have tried anything I can found on google. Like
add bind-address = 127.0.0.1 to cnf file, and comment out the skip-networking.
I also tried the answer on another question Can't connect to remote server using MySQL Workbench on mac, which allow all machine can access to the service.
But my PC still can't connect to it, which report code 10060 error. So what should I do?
That bind-address = 127.0.0.1 config option means that your mysql server only accepts connections from the localhost, which is your actual CentOS machine. Make sure to set bind-address = 0.0.0.0.
Also, make sure that:
you have connectivity from your windows machine to the CentOS one
no firewall blocks the external connections to the local mysql port
Regarding potential security concerns from opening your mysql instance to the whole internet - first make it work, then make it better
I had the same issue here man,and i discovered that we need to create a user that isnt the root user. I my case, i don't know why yet, the issue was that.
The solution
Steps:
1 - Check the firewall (create a rule for port 3306 or disable it).
2 - Comment the line # bind-address=0.0.0.0 at [mysqld] config optin in C:\ProgramData\MySQL\MySQL Server 5.7\my.ini
3 - Create the user to remote access:
mysql> CREATE USER 'net'#'%' IDENTIFIED BY '123';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'net'#'%' WITH GRANT OPTION;
In my case, solved.
Using MySQL Workbench in Windows 7 how can I bind my MySQL Server to my IP Address instead of 127.0.0.1 and how can I give users from different hosts access to it?
From here:
Open a DOS command prompt on the server.
Run the following command from the mysql\bin directory:
mysql -u root --password=
A mysql prompt should be displayed.
To create a remote user account with root privileges, run the following commands:
GRANT ALL PRIVILEGES ON . TO 'USERNAME'#'IP' IDENTIFIED BY 'PASSWORD';
It depends on hosting server on which the database is hosted e.g. by Hostgator hosting you may bind IPs to access the database remotely, you will have to provide access to user IPs in the hosting. For other like Go Daddy it depends on while creating the database, you will have to select for remote database option which generated a url likewise a host with which database can be accessed with SQLYog/Workbench.
My Answer is you can't bound the IPs with database tools but only with hosting servers.
We have a MySQL server in one of the remote Virtual Machine (Windows Server 2008). Till yesterday we were able to connect to the MySQL server, with the help of workbench installed in our local machine.
Yesterday there was a restart to the machine which has the Virtual Machine installed. After that we are unable to connect to MYSQL. Though I can ping and remote connect this particular VM. I can even execute the queries inside the workbench installed in the VM.
I am not too good at networking or security related stuffs. Please help me to solve this issue.
Error :
Your connection attempt failed for user 'root' from your host to server at ABC:3306: Can't connect to MySQL server on 'ABC' (10060)
Really this could be a magnitude of possible reasons, hopefully this is a start:
Check basic network
From the MySQL virtual machine open up a command prompt and type IPCONFIG /ALL. This will show you all the IP addresses bound to different network adapters.
Check that the IP address you're connected to is listed there, the virtual machine might have got a new IP from DHCP rather than having a static IP after its restart.
Hostname vs IP
You should check the hostname resolution, from your quoted error it would suggest you are you are connecting to a hostname rather than a server IP. Check your machine can resolve to the hostname using the correct IP address - it could also be worth changing the hostname for the actual IP of the server in the connection string.
MySQL config file
You've said you're running MySQL on Windows, it was customary to rename the my.cnf to my.ini. The configuration file for older versions of MySQL previous to 4.1.5 was usually stored in either c:\my.ini or c:\windows\my.ini. For versions after this the default location is the installation directory usually %PROGRAMDATA%\MySQL\MySQL Server xxx.
When you have located the configuration file please open it on Notepad (or similar text editor), locate the [mysqld] section and make sure that port= the port you're trying to connect to and bind-address= the IP address you're trying to connect to.
Server ports
From the MySQL virtual server open a command prompt and type netstat –ano, this will show you a list of processes and what IP's / ports they are listening on. The MySQL server should be listed here and should be listening on the same port and IP as the config file defines.
Windows firewall
You should have a firewall rule to allow MySQL, the following will add one on the default port of 3306
netsh advfirewall firewall add rule name="MySQL Server" action=allow protocol=TCP dir=in localport=3306
Identify if this is machine specific
You could setup the MySQL Workbench application on another workstation and try to connect to identify if this is a global problem or just one related to your specific workstation.
mysql administrator of your database should allow remote connection to the mysql server.
change this in my.cnf:
bind-address = 127.0.0.1 # this shoul be your mysql server ip
and comment this:
# skip-networking
Chances are that your configuration was set up for an IP that has changed. By default, mysql won't let you connect from remote hosts unless you explicitly give permissions for a specific user on a specific schema or a group of schemas, for example if you did something like this:
GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'#'1.2.3.4' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;
Maybe what you actually did was to set the grant onto your own IP address, that is the address of your local machine, and if your local machine (not the remote server) has changed it's IP address, then mysql will not let you connect unless you have the "1.2.3.4" IP address which obviously you don't have anymore if you have a dynamic IP address (common with DSL/Cable connections)
So connect through SSH or Telnet or whatever you use to your windows server and go to mysql as root and do this:
SELECT * from information_schema.user_privileges;
That will show you the grants on all users and how they are allowed to connect. If you don't see your local IP Address listed there or a wildcard (which would allow you to connect from any remote machine to the server) then you have to set it up like this:
GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'#'%' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;
Where USERNAME of course is your user. See that after the on there is a wildcard / dot /wildcard that means you want that user to be able to connect to any schema (database, for mysql) from any user from any network. But I'd recommend that you only do the grant for the user for the specific schema you need to connect to.
Then after that, if you actually had the right information and still can't connect than use a portscanner like nmap or something like that to do a port scan and see if mysql is:
Open and listening to external network
Running on the port that you actually want to connect through
If 1 is true, then check 2 because maybe there is a misconfiguration of the port. But if any of these 2 points do work then it sounds definitely not like a network configuration but a user setting or something else.
GRANT ALL ON *.* to user#'%' IDENTIFIED BY 'password';
this command should do the trick for all users #Gustavo Rubio has already given the proper explanation.
To ensure what ports are open run cmd in the virtual machine and type.
netstat -a
TCP 127.0.0.1:3360 Hostname:3360 LISTENING
The my.cnf is located Mysql-install-path\MySQL\MySQL Server xxx make sure you backup original before changing
Can't connect to [local] MySQL server
Testing The MySQL Server Installation on Microsoft Windows
MySQL Workbench: Manage MySQL on Windows Servers the Windows way
For the first time you need to test and make sure your connection to mysql is not blocked by the firewall.
To disable the firewall on each host in your cluster, perform the following steps on each host.
1. Save the existing iptables rule set.
iptables-save > /root/firewall.rules
2. Disable iptables.
For RHEL, CentOS, Oracle, and Debian:
chkconfig iptables off
and
/etc/init.d/iptables stop
For SLES:
chkconfig SuSEfirewall2_setup off
and
rcSuSEfirewall2 stop
For Ubuntu:
service ufw stop
https://www.cloudera.com/documentation/enterprise/5-7-x/topics/install_cdh_disable_iptables.html
Depends on your setup, but if you're using cPanel just go to RemoteMYSQL and enter your host. You can also use a wildcard. Below worked for me when I was getting the error
"Could not connect to DB server '' as user ''. port : Host '' is not
allowed to connect to this MySQL server"
On MySQL v5.6 this may be the case.
When another server communicate by advertising its hostname instead of IP address, the resolution might fails (because your user is using IP address instead of hostname for example).
So, you need to disable the following,
skip-host-cache
skip-name-resolve
Or maybe create the user with appropriate hostname (instead of IP address). You may find the hostname when establishing the connection to the remote MySQL.
Environment:
I have a database on CentOS
The folder where it is saved is shared using SAMBA
Windows have access to the files at \\192.168.1.101\mysql\food\
MySQL-server is running on both systems
Problem:
I need to access the database on windows using mysql from CMD
Extra info:
I open mysql on CMD by running:
C:\Program Files\MySQL\MySQL Server 5.6\bin>mysql -h localhost -u root -p
mysql>
I can not display the table on \\192.168.1.101\mysql\food\ because is not the default folder for mysql
Question:
how can i change the default folder on mysql-windows to open my database? do I need something else to display the database? like add a user to mysql-server on centos and grant access
you can connect to a different host by running mysql -h 123.45.67.89. Please note that there are a few security implications:
1.You will have to grant yourself access. You will need to run something like GRANT ALL on db_name.table TO user#your_ip IDENTIFIED BY 'password'.db_name, table and your_ip can be * but beware of opening your server to hackers.
2.ou will have to open your server's firewall if you are not on the same LAN. Again, ymmv and you should be aware not to open the door to exploits.
3.You may want to use SSL( http://dev.mysql.com/doc/refman/5.1/en/mysql-command-options.html#option%5Fmysql%5Fssl ) and use secure-auth( http://dev.mysql.com/doc/refman/5.1/en/mysql-command-options.html#option%5Fmysql%5Fsecure-auth ) in order to protect your traffic and credentials.
Hope that helps.Thanks to you
I have my dev environment set up as a Ubuntu Server (with LAMP installation) inside a vmware. The vmware is running on my local windows 7 machine. When I try to access my mysql server via HeidiSQL program the connection fails. I get a:
Server Error 2003, can't connect to mysql server on <IP ADRESS HERE>
I can however access the db server via PhpMyAdmin. MySQL is running and my connection credentials and port are all correct.
I read that you should enter the IPs of the computer you are trying to connect from as the "bind address" in the my.cnf file. Which I did. I tried both the internal network IP as well as the online IP. Still no luck, same message.
Since this isn't a production environment I would ideally like to allow anyone to access that server, not limit it by IP. Especially since my ISP assigns dynamic IPS. So I would have to change it all the time, assuming that even works.
So does anyone know how I can connect to my MySQL server from a remote computer?
P.S. I assume this is something developers have to deal with that's why I posted it here and not Super User. If it must be migrated please send it to Server Fault not Super User.
Ok, be aware this gives the world and his dog access to your mysql server.
GRANT ALL ON *.* to '%'#'%' WITH GRANT OPTION;
But say you are on your home network of 192.168.1.2/16 then you can at least limit it like this.
GRANT ALL ON *.* to '%'#'192.168.%' WITH GRANT OPTION;
Another option is that you have a user and password but want to connect from anywhere
GRANT ALL ON *.* to 'mysecretuser'#'%' IDENTIFIED BY 'mysecretpassword' WITH GRANT OPTION;
first check the ip assigned to vmware using from cmd
ipconfig/all
suppose ipassigned to vmware is 192.168.11.1
now in vmware in ubuntu check the ipadress
ifconfig
suppose ip adress of ubuntu is 192.168.11.137
now open mysql configurations
sudo nano /etc/mysql/my.cnf
change the bind address to ubuntu ip address
bind-address = 192.168.11.137
restart mysql
now connect to mysql
mysql -u root -p
and create a user with all privileges and host ip of vmware i.e 192.168.11.1
GRANT ALL ON db.* TO user#'192.168.11.1' IDENTIFIED BY 'PASSWORD';
now try to connect from windows.
also open port of mysql
/sbin/iptables -A INPUT -i eth0 -p tcp --destination-port 3306 -j ACCEPT
restart mysql and try to connect on ubuntu host ip address 192.168.11.137
For Heidi SQL I was able to get it to work following the instructions on this article:
http://mysql-tools.com/en/articles/http-tunnel/73-heidisql-a-http-tunnel.html
It uses a program called HTTP Tunnel. It's a lot slower but at least it works. If you use Navicat it comes with a PHP file that you can upload to your server and it will connect via that.
