四.设置 MySQL 服务开机自启动
通过 service mysql start | stop | restart 管理 mysql 服务

# cp support-files/mysql.server /etc/rc.d/init.d/mysqld 设置使mysql每次启动都能自动运行

# chkconfig --add mysqld

# chkconfig --level 345 mysqld on

# service mysqld start //启动mysqld服务

五.设置全局登录

通过 # mysql 直接登录

export PATH=$PATH:/data/mysql5/bin
