linux 建立 MySQL 账号

以 root 身份登录 Linux 系统，创建 mysql 组和用户 [root@Nagios-Server ~]# groupadd mysql

[root@Nagios-Server ~]# useradd mysql -g mysql -M -s /sbin/nologin [root@Nagios-Server ~]# tail -1   /etc/passwd mysql:x:501:501::/home/mysql:/sbin/nologin

目前使用 mysql 版本比例：

Mysql 5.1 –20%   Mysql 5.5 –60%   Mysql 5.6 –20%
