CentOS 7安装完成后初始化的方法

1、添加用户

新增名为"wang"的用户

[root@vdevops ~]# useradd wang #添加账户
[root@vdevops ~]# passwd wang #设置密码
Changing password for user wang.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.
[root@vdevops ~]# exit #退出
以用户"wang"为例，设置其为唯一拥有管理员权限的账户
[root@vdevops ~]# usermod -G wheel wang
[root@vdevops ~]# vim /etc/pam.d/su
[html] view plain copy print?
#%PAM-1.0

# Uncomment the following line to implicitly trust users in the "wheel" group. 
#auth sufficient pam_wheel.so trust use_uid
