When you get this error have you confirmed that mysqld is actually
running, e.g., with a "ps"?

What is the output from:

  /etc/rc.d/init.d/mysqld status

Normally the socket file is:

  /var/lib/mysql/mysql.sock

(note the capitalization).

If mysql is running, check the name (including capitalization) of
the socket directory/file. If it's (the standard) lowercase, then
check the client software configuration to see if there's something
pointing to the mixed-case form that your error is showing. [The
default location for the mysql configuration file is /etc/my.cnf,
but it can be in other locations.]
