Remote Connections Mysql Ubuntu

You are using ubuntu 12 (quite old one)

First, Open the /etc/mysql/mysql.conf.d/mysqld.cnf file (/etc/mysql/my.cnf in Ubuntu 14.04 and earlier versions

Under the [mysqld] Locate the Line, bind-address = And change it to, bind-address = or comment it

Then, Restart the Ubuntu MysQL Server systemctl restart mysql.service

Now Ubuntu Server will allow remote access to the MySQL Server, But still you need to configure MySQL users to allow access from any host.

User must be 'username'@'%' with all the required grants

To make sure that, MySQL server listens on all interfaces, run the netstat command as follows.

netstat -tulnp | grep mysql

Hope this works !

MySQL only listens to localhost, if we want to enable the remote access to it, then we need to made some changes in my.cnf file:

sudo nano /etc/mysql/my.cnf

We need to comment out the bind-address and skip-external-locking lines:

#bind-address =
# skip-external-locking

After making these changes, we need to restart the mysql service:

sudo service mysql restart

To expose MySQL to anything other than localhost you will have to have the following line

For mysql version 5.6 and below

uncommented in /etc/mysql/my.cnf and assigned to your computers IP address and not loopback

For mysql version 5.7 and above

uncommented in /etc/mysql/mysql.conf.d/mysqld.cnf and assigned to your computers IP address and not loopback

#Replace xxx with your IP Address 
bind-address        =

Or add a bind-address = if you don't want to specify the IP

Then stop and restart MySQL with the new my.cnf entry. Once running go to the terminal and enter the following command.

lsof -i -P | grep :3306

That should come back something like this with your actual IP in the xxx's

mysqld  1046  mysql  10u  IPv4  5203  0t0  TCP (LISTEN)

If the above statement returns correctly you will then be able to accept remote users. However for a remote user to connect with the correct priveleges you need to have that user created in both the localhost and '%' as in.

CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'mypass';
CREATE USER 'myuser'@'%' IDENTIFIED BY 'mypass';


GRANT ALL ON *.* TO 'myuser'@'localhost';
GRANT ALL ON *.* TO 'myuser'@'%';

and finally,


If you don't have the same user created as above, when you logon locally you may inherit base localhost privileges and have access issues. If you want to restrict the access myuser has then you would need to read up on the GRANT statement syntax HERE If you get through all this and still have issues post some additional error output and the my.cnf appropriate lines.

NOTE: If lsof does not return or is not found you can install it HERE based on your Linux distribution. You do not need lsof to make things work, but it is extremely handy when things are not working as expected.

UPDATE: If even after adding/changing the bind-address in my.cnf did not work, then go and change it in the place it was originally declared:


Add few points on top of apesa's excellent post:

1) You can use command below to check the ip address mysql server is listening

netstat -nlt | grep 3306

sample result:

tcp 0  0*   LISTEN

2) Use FLUSH PRIVILEGES to force grant tables to be loaded if for some reason the changes not take effective immediately

GRANT ALL ON *.* TO 'user'@'localhost' IDENTIFIED BY 'passwd' WITH GRANT OPTION;

user == the user u use to connect to mysql ex.root
passwd == the password u use to connect to mysql with

3) If netfilter firewall is enabled (sudo ufw enable) on mysql server machine, do the following to open port 3306 for remote access:

sudo ufw allow 3306

check status using

sudo ufw status

4) Once a remote connection is established, it can be verified in either client or server machine using commands

netstat -an | grep 3306
netstat -an | grep -i established
