    Ok, here is where we are so far:

    The /tmp/mysql.sock is a symbolic link to /var/lib/mysql/mysql.sock

    Which in my case does not exist. From my understanding mysql creates mysql.sock on startup. The permissions on the directory are fine, yet No Go, still same error.

    Of note this error began upon downgrading from 4 to 3. Upgrading back to 4 did not fix.

    I had been running MySQL 4 for over a month with no problems. Then I updated to WHM 7.1.0 cPanel 7.1.0-R20. Still no problems at this point. Then I updated /scripts/easyapache to the July 1st build. At that point MySQL gave me the following error:

    Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)


    Then after trying some of the suggestions the error changed to this:

    Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)


    I followed the directions in all of the related posts and nothing seemed to work for me. So here is what I did to finally make it work:

    I read a post at the RackShack forum that the following needed to be in the /etc/my.cnf file:

    [mysqld]
    set-variable = max_connections=500

    [client]
    port = 3306
    socket = /tmp/mysql.sock
    [mysqld]
    port = 3306
    socket = /tmp/mysql.sock


    I only had the first 2 lines, so I added the [client] and [mysqld] parts.


    Then I shut down mysql and chkservd with the following commands:

    service mysql stop
    /etc/rc.d/init.d/chkservd stop


    Then I removed the following files:

    rm -rf /tmp/mysql.sock
    rm -rf /var/lib/mysql/mysql.sock


    Now restart mysql and chkservd with the following commands and mysql will create the mysql.sock file in the /tmp directory as oulined in the updated my.cnf file:

    service mysql start
    /etc/rc.d/init.d/chkservd start


    Now create the softlink with this:

    ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock


    There were a couple of variations in that last last command to create the softlink. I guess it depends on where mysql creates the mysql.sock file when it starts. So if you are trouble shooting you might shut down mysql as shown above, then remove the mysql.sock files. Then restart mysql as shown above and see where it creates the mysql.sock file. If it creates it in the /tmp directory then you need the softlink command shown above. If it creates the mysql.sock file in the /var/lib/mysql directory then you problaby need to use the softlink command like this as shown in some of the other related posts:

    ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock


    That worked for me. Hope this helps someone down the line.
