List the listening ports and check if mysql is listed on it.
$ netstat -tln | grep mysql
If you cannot find the port number for mysql view my.cnf file to see if you can find the port number. If you see a line “skip-networking” try commenting out the line and then restart mysql daemon.
$ vi /etc/my.cnf
[mysqld]
set-variable=local-infile=0
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1
skip-networking
[mysql.server]
user=mysql
basedir=/var/lib
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
$ service mysqld restart
