# yum -y install mysql mysql-server
2. Enable MySQL on boot and start MySQL server
# chkconfig --levels 235 mysqld on
# service mysqld start
Make sure the MySQL server is running:
# netstat -tap | grep mysql
tcp 0 0 *:mysql *:* LISTEN 28179/mysqld
3. Set password for user root
# mysqladmin -u root password your_password
