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 mysqltcp    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
