[root@localhost ~]# groupadd mysql
[root@localhost ~]# useradd -g mysql mysql
[root@localhost ~]# cd /usr/local
[root@localhost ~]# gunzip < /PATH/TO/MYSQL-VERSION-OS.tar.gz | tar xvf -
[root@localhost ~]# ln -s FULL-PATH-TO-MYSQL-VERSION-OS mysql

[root@localhost mysql]# scripts/mysql_install_db --user=mysql
[root@localhost mysql]# chown -R root  .
[root@localhost mysql]# chown -R mysql data
[root@localhost mysql]# chgrp -R mysql .

更改密码:
[root@localhost mysql]#./bin/mysqladmin -u root password 'new-password'
[root@localhost mysql]#./bin/mysqladmin -u root -h localhost.localdomain password 'new-password'

开机自动启动:
在/etc/rc.local中加入:
