I am unable to connect to on my ubuntu installation a remote tcp/ip which contains a mysql installation:

viggy@ubuntu:~$ mysql -u user.name -p -h xxx.xxx.xxx.xxx -P 3306
Enter password: 
ERROR 2003 (HY000): Can't connect to MySQL server on 'xxx.xxx.xxx.xxx' (111)

I commented out the line below using vim in /etc/mysql/my.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           =

Then I restarted the server:

sudo service mysql restart

But still I get the same error.

This is the content of my.cnf:

(Note that I can log into my local mysql install just fine by running mysql (and it will log me in as root) and also note that I can get into mysql in the remote server by logging into via ssh and then invoking mysql), but I am unable to connect to the remote server via my terminal using the host, and I need to do it that way so that I can then use mysql workbench.

  • It would probably help if you posted your entire my.conf and the contents of your firewall rules. – MDMarra Nov 8 '12 at 18:26
  • @MDMarra I added the entire my.cnf to the question and I dont have any firewall, other than whats in my router. This is the default ubuntu installation. – JohnMerlino Nov 8 '12 at 18:45

It appears you correctly commented out the bind-address directive in my.cnf. But this change needs to be made on the remote server in order to have any effect there; while you seem to have made the change on your local machine. Therefore the change only has effect on your local mysqld, and not the remote mysqld you're trying to access. So you need to ssh into the remote machine and make the change on the remote machine (and then restart mysqld there). You'll also have to check the remote machine's firewall to ensure that it allows you access.

  • Im going to try an ssh tunnel to bypass firewall – JohnMerlino Nov 9 '12 at 2:46
  • I used an ssh tunnel and it worked. – JohnMerlino Nov 9 '12 at 4:06

This could be a user permissions problem. What did you use for your CREATE_USER?

Try making a new user with

CREATE USER 'testuser' IDENTIFIED BY 'somepass';

leave out the normal @'locahost' part so it isn't restricted.

also have a look at /var/log/mysql and see if there are clues...

  • I can connect to localhost fine, Im trying to connect to a remote ip address in this situation. – JohnMerlino Nov 8 '12 at 19:48
  • was there anything of not in the /var/log/mysql file? – user916499 Nov 8 '12 at 22:18

Since you don't have permission to connect directly to the MySQL server on the remote host but have the ability to use ssh, forward a port through ssh and then connect MySQL Workbench to that port.


I had the same problem trying to connect to a remote mysql db.

I fixed it by opening the firewall on the db server to allow traffic through:

sudo ufw allow mysql

Try with

mysql -u username -h xxxx.xxxx.xxx.xxxx -P portnumber -D mysql -p

Enter password: ***********

Note -P "P" capital lettre and -D "D" capital also
