昨天初始化mysql数据库，今天开机进行相关调优、配置
首先查看到mysql开机没有
[root@dataserver ~]# ss -lntup|grep mysql
配置/etc/rc.local 将mysql设置为开机启动
方法一、
[root@dataserver ~]# vim /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
/etc/init.d/mysqld start

"/etc/rc.local" 8L, 245C 已写入
[root@dataserver ~]# reboot
[root@dataserver ~]# ss -lntup|grep mysql
tcp LISTEN 0 50 *:3306 *:* users:(("mysqld",1459,10))方法二、
[root@dataserver ~]chkconfig --add mysqld
[root@dataserver ~]chkconfig mysqld on
[root@dataserver ~]reboot
重启查看是否生效
[root@dataserver ~]# reboot
