centos 7怎么启动mysql

1、设置开机自启动

chkconfig mysqld on

2、/etc/init.d/mysqld start

/etc/init.d/mysqld stop

3、centos6以前

services mysqld start

services mysqld stop

4、centos7需要用systemctl

systemctl start mysqld

systemctl stop mysqld

centos7自带是mariadb，一个mysql的变种。查看有没有安装过：yum list installed mysql*rpm -qa | grep mysql*安装mysql软件（mariadb）yum install mysql*启动mysqlsystemctl start mariadb.service 或者 systemctl start mysqld.service结束systemctl stop mariadb.service 或者 systemctl stop mysqld.service重启systemctl restart mariadb.service 或者 systemctl restart mysqld.service开机自启systemctl enable mariadb.service 或者 systemctl enable mysqld.service
