CentOS 为Mysql建立用户组
1、建立CentOS Mysql用户组 [root@localhost ~]# grep mysql /etc/group #查询 系统 中是否有mysql这个用户组,没有则添加。 [root@localhost ~]# groupadd mysql #增加一个名为 Mysql的用户组 2、建立CentOS Mysql用户 [root@localhost ~]# grep mysql /etc
1、建立CentOS Mysql用户组
[root@localhost ~]# grep mysql /etc/group
#查询系统中是否有mysql这个用户组,没有则添加。
[root@localhost ~]# groupadd mysql
#增加一个名为 Mysql的用户组
2、建立CentOS Mysql用户
[root@localhost ~]# grep mysql /etc/passwd
#查询系统中是否有mysql这个用户,没有则添加。
[root@localhost ~]# useradd mysql -g mysql -M -s /sbin/nologin
#增加一个名为CentOS Mysql的用户。
-g:指定新用户所属的用户组(group)
-M:不建立根目录
-s:定义其使用的shell,/sbin/nologin代表用户不能登录系统。
之前讲解过MYSQL的编译安装,所以安装步骤这里就省略掉了
