replace the 'server.domain.com' with the hostname of your mysql host; you can find that by reviewing the .err file in the /var/lib/mysql/ files. The tail command will return 200 lines of your error log this can post back to us and may help us refine more specifics surrounding the problem you are experiencing. You run the tail command in the command line. If for any reason your .err logs are not stored in your /var/lib/mysql/ then locate your .err by doing a search for this extension and noting the location of this file.
