Since you just installed MySQL i can recommend you a few things.

  • Make sure the MySQL user and group is present id mysql if not, create them groupadd mysql; useradd mysql -g mysql -M -s /bin/false
  • Make sure the MySQL Data folder user and group are set to mysql user and group chown -R mysql.mysql /var/lib/mysql where /var/lib/mysql is the path to your MySQL data folder (ie.: /var/lib/mysql is a default place but it may be somewhere else depending on how have you installed it).
  • If you don't know where your data directory is, you can check your init mysql script that is inside /etc/init.d and look for the entry --datadir=
  • Before you can run MySQL, you must have a database. To install an initial database, do this as root: scripts/mysql_install_db

Seems that the mysql daemon don't start up.

Have you tried to check log of mysql in /var/log/mysql ?

for check the status of a daemon in Linux you could type this in your terminal : /etc/init.d/mysql status

but seems that your mysql server doesn't start up, therefore the status of the process should be "not running" .
