yum install mysql
yum install mysql-server
yum install mysql-devel
chgrp -R mysql /var/lib/mysql
chmod -R 770 /var/lib/mysql
service mysqld start
mysql
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('secret_password');
 

如要其他机器能访问,在mysql.user中添加一个Host'%'user,然后flush priviledges;,最后防火墙加一句类似这样的语句即可(开通3306端口):

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

如果要reboot自启动:

chkconfig --levels 345 mysqld on
