I have a unix server with mysql which I am trying to access from my machine. To clarify, access the mysql server. When I do I get this error.
Connecting to MySQL server 192.168.1.25...
Can't connect to MySQL server on '192.168.1.25' (10061)
Here are my credentials:
username: root
port: 3306
The server is running because I am able to remotely login onto the machine (with ip: 192.168.1.25" and then run mysql from root. What do you think is going on:
Is it a firewall issue?
Accessing as 'root' is being denied?
I am new to mysql.
1)
check the logs
you can see where the logs are by checking the my.cnf file.
mysqld.log might be the file name, but where
2)
a. see if it's a network issue.
telnet 192.168.1.25 3306
b. see if the service is at that port.
ssh to the box
# from the local host
mysql -u root
telnet 127.0.0.1 3306
ps auxw|grep mysql
you should hopefully have enough diagnostic info at this point to figure it out.
Probably because remote root login is not allowed. You can try this article on how to enable remote root:
http://benrobb.com/2007/01/15/howto-remote-root-access-to-mysql/
i have this problem and fix it by
first you must grant all to user
GRANT ALL PRIVILEGES ON databasename. TO 'user'#'%' IDENTIFIED BY 'password';
then
FLUSH PRIVILEGES;
and change the mysql config using
sudo nano /etc/mysql/my.cnf
find "bind-address" row and comment it.
save config and restart mysql using
sudo /etc/init.d/mysql restart
hope solve problem :)
The Message (10061) is do to offline severs or firewall blockage
If you get -the name of your pc - can not connect, then mysql is rejecting the connection and you will have to create a 'user' in the mysql database mysql, table user using the IP of the remote connection', and restart the database service
but for error 10061 check The Firewall in both machines.
Masters PC per say, is the one with the phpmyadmin installation
Allow Destination ip-[the remote] and port 3306 on the Master Machine
and
Allow source ip-[the masters]/with any port, and check your destination port(3306) too. destination ip can also be set on some firewalls.
And if you can, search in your firewall for logs, settings, recent activity, etc... to see what and how you are being blocked.

I have visited many websites for remote connection of MariaDb.
I have executed the command as below to create user with password in sql.
GRANT ALL PRIVILEGES ON . TO 'root#(my server ip)' IDENTIFIED BY '(my password)'
And i've added one line below [mysqld] in the file of /etc/my.cnf.d
bind-address = 0.0.0.0
Then restart MariaDb service as below
sudo systemctl restart mariadb
Everything runs good.
However when i access by below command, it runs failed.
mysql -u root -p -h (my server ip)
I've turn off my firewall in my server, and turn on the port 3306 in GCP server, and it can be expected, i must fail to connect in my local machine.
Since you want to use a TCP connection, I assume that you want to connect to a remote server, not to a server running on the same machine.
Make sure that you are able to connect physically to the database server, e.g. with telnet server_ip:3306.
Determine the IP address of the computer from which you want to connect to the server (= client_ip).
Add a user on the server:
GRANT ... TO root#client_ip
If client and server are running on the same machine, the preferred way is to use a linux socket (user#localhost) which is way faster.
I've currently set up a staging area for my app in Digital Ocean with LAMP stack. The Framework for my app is Laravel 5.5 and Vue 2x.
In development, I've been using remote MySQL and had no issues with the connection error. However, when I moved it to the staging env, it is giving me access denied error. When I looked at it closely to the error log, Access denied is for username#[digital-ocean-droplet-ip], whereas I have properly configured the MySQL credentials to the remote host IP under laravel's config/database file.
So, I am doubtful if I have to do any configuration under Apache to allow any external MySQL connection? I forgot the cmd but I did allow sfw firewall allow to any port 3306 to the remote server IP address in Apache.
Any help is appreciated.
Thanks!
MySQL by default does not create an user with access from remote connections.
First you need to create an user on database that allows connection from outside (%) or a specific IP
CREATE USER 'newuser'#'%' IDENTIFIED BY 'password';
Than give him privileges
GRANT ALL PRIVILEGES ON *.* TO 'newuser'#'%';
The *s could be replaced by your database and table name respectively
You might also check if in your mysql configuration(/etc/mysql/mysql.conf.d/mysqld.cnf in my case) has this line uncommented
bind-address = 127.0.0.1
Change the ip if necessary
restart mysql and apache
sudo service apache2 restart
sudo service mysql restart
Than update the user and password at your .env file and try again!
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.
In Google Compute Engine, LAMP installed using 'click to Deploy'. I have enabled ALLOW HTTP,HTTPS traffic also in the API console.
I couldn't connect MySQL via Toad. I tried the following Connection Type 1.SSH, 2.TCP, 3.SSL.
Refer this image:
.
I got issues while connecting through any of these three connection types. How to connect MySQL(created using GCE) via Toad?
I used SSH keys also, is there any specific method to connect to this mySQL created via GCE?
My remote server my.cnf file
If you want to connect to Mysql from a remote PC with Toad:
1) Add a firewall rule in the Developer Console Compute Engine network page to allow tcp:3306 (mysql port) to your IP or to everyone (0.0.0.0/0, easier but not secure) and then use Toad TCP connection.
2) Check that mysql user accepts connections from your IP or from every IP (%) or create a new mysql user. You can connect to instance in SSH and give the following commands to create a new Mysql user:
mysql -u root -p
then create user (change 'newuser' and 'password' according to your needs) :
CREATE USER 'newuser'#'%' IDENTIFIED BY 'password';
Grant user permission:
GRANT ALL PRIVILEGES ON * . * TO 'newuser'#'%';
FLUSH PRIVILEGES;
exit;
If connection still fails:
3) Check that mysql is listening on all IP addresses, for Debian see in /etc/mysql/my.cnf and change bind-address to :
bind-address = 0.0.0.0
and restart mysql:
/etc/init.d/mysql restart
Hope this helps.
Sincerely,
Paolo
Id try to access mysql from another server in the same network and project to help narrow down where your requests are getting blocked. If you can access mysql from another instance then it could be your firewall rules.
Also, does debian have iptables or another software firewall enabled by default?
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

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.
