I installed mysql server on linux box IP = 192.168.1.100 but when i try to connect to this IP it alway error(111). but use localhost and 127.0.0.1 is OK.

beer@beer-laptop# ifconfig | grep "inet addr"          inet addr:127.0.0.1  Mask:255.0.0.0          inet addr:192.168.1.100  Bcast:192.168.1.255  Mask:255.255.255.0beer@beer-laptop# mysql -ubeer -pbeer -h192.168.1.100ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.1.100' (111)beer@beer-laptop# mysql -ubeer -pbeer -hlocalhostWelcome to the MySQL monitor.

Connect from another machine it also error 111.

How difference between use localhost/127.0.0.1 and 192.168.1.100 in this case. I don't know how to connect to this database from another machine.

Help please. Thank.

It probably means that your MySQL server is only listening the localhost interface.

If you have lines like this :

skip-networkingbind-address = 127.0.0.1

In your my.cnf configuration file, you should comment them (add a # at the beginning of the lines), and restart MySQL.

Of course, to do this, you must be the administrator of the server.

111 means connection refused, which in turn means that your mysqld only listens to the localhostinterface.

To alter it you may want to look at the bind-address value in the mysqld section of your my.cnffile.

If all the previous answers didn't give any solution, you should check your user privileges.

If you could login as root to mysql then you should add this:

CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY  '***';GRANT ALL PRIVILEGES ON * . * TO  'root'@'192.168.1.100' IDENTIFIED BY  '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100. It should work.

i don't think that user privileges related error would give error 111.

If you're running cPanel/WHM, make sure that IP is whitelisted in the firewall. You will als need to add that IP to the remote SQL IP list in the cPanel account you're trying to connect to.
