mariadb安装
在centos7上，直接yum install mysql-server将默认安装mariadb，如果配置了mysql的yum源，需要指定"mysql-community-server"才表示安装mysql。

配置服务service开机启动
如果MySQL安装在/usr/local/mysql下，datadir为/usr/local/mysql/data，参数文件为/etc/my.cnf，/usr/bin/my_print_defaults存在，则可以直接使用$MYSQL_HOME/support-files/mysql.server文件；如果安装在其它路线下，那么需要做其他的额外设置，比较麻烦:
1 2 3 4 5 6 7 | cp ./support-files/mysql.server /etc/init.d/mysql57193307 chmod 755 /etc/init.d/mysql57193307 chkconfig --add mysql57193307 chkconfig mysql57193307 on chkconfig --level 345 mysql57193307 on service mysql57193307 start systemctl status mysql57193307 |
service
其它情况可以使用以下脚本：
