[root@vm3547 etc]# cd rc.d/init.d [root@vm3547 init.d]# mysql restart error 2002 (hy000): can't connect local mysql server through socket '/var/lib/mysql/mysql.sock' (111)
it seems have existing /var/lib/mysql/mysql.sock file 1 of previous terminated runs. "restart" (as opposed "start") means "try stopping , starting again". there socket file in place, tries stop instance on port - , fails, there nothing there running.
delete invalid file.
