# groupadd mysql
# useradd -s /sbin/nologin -g mysql -Mmysql
#注意：useradd命令参数简要说明
#1、-s /sbin/nologin 表示禁止该用户登录，加强安全
#2、-g 指定属于mysql组
#3、-M表示不创建用户家目录
# mkdir -p /data/{3307,3308}/data
目录解析：
/data 实例的总目录
/data/3307 3307实例的目录
/data/3308 3308实例的目录
/data/3307/data 3307实例的数据目录
/data/3308/data 3308实例的数据目录
注意：生产硬件配置：MEM 32g、双CPU8core、硬盘6*600g sas 15k/rpm 2-3个实例

登录有两种方法：
mysql -uroot -p -S/data/3307/mysql.sock
mysql -h127.0.0.1 -uroot -p --port=330X
注意：如果指定socket文件，则不需要-h127.0.0.1或者-h localhost,同时，也不需要指定--port=330X端口号
