    In WHM, go to Setup Remote MySQL server - pretty self explanatory after that. It's listed step by step in the cPanel documentation:

    I read Document, and get this error. So how to resolve this ?

    Code:
        mysql started ok

Done
Testing new mysql setup...Failed to connect to the remote mysql host:

/usr/bin/mysqladmin: connect to server at '85.17.x.x failed
error: 'Can't connect to MySQL server on '85.17.154.x' (4)'
Check that mysqld is running on 85.17.x.x and that the port is 3306.
You can check this by doing 'telnet 85.17.x.x 3306'


Restoring old mysql config. Please resolve the above error and try again.

    Hello :)

    Could you run the "telnet" command from your server as listed in the error message and post the results here?

    Code:
    telnet 85.17.x.x 3306
    Thank you.

    Michael,

    Why does one need Telnet for remote MySQL? Surely this is VERY insecure?

    I resolved this 3306, cause by ServerOne install CSF and not open port TCP OUT 3306. BUt a problem arise:
    - I can't backup my db on ServerOne ( I used to backup succesfully with this, but after using remote , It's stop)

    Code:
    mysqldump: Got error: 1044: Access denied for user 'megxxx_for'@'66.x.x.x' to database 'megxxx_for' when selecting the database
    note: 66.x.x.x is ip ServerOne

    After switching to using remote SQL, the db connection will not work until you go to cpanel for that domain, and visit the mySQL page in cPanel... just load this page in your browser.

    I dont know if it is a bug, or by design - but I can say that you need to do this for each cpanel account, if you expect the db connection (username and password) to work.
