centos添加普通用户

centos添加普通用户流程

添加普通用户

[root@localhost ~]# adduser dadi

密码

[root@localhost ~]# passwd dadi

密码设置过于简单的话会有提示

先查看权限

[root@localhost ~]# ls -l /etc/sudoers
-r--r----- 1 root root 4002 Mar  1  2012 /etc/sudoers

修改权限，增加写权限

[root@localhost ~]# chmod -v u+w /etc/sudoers
mode of `/etc/sudoers' changed to 0640 (rw-r-----)

添加新用户

[root@localhost ~]# vim /etc/sudoers

## Allow root to run any commands anywhere 
root	ALL=(ALL) 	ALL
dadi    ALL=(ALL)       ALL  #This is a new user
## Allows members of the 'sys' group to run networking, software, 
## service management apps and more.

保存修改的文件，ESC 退出编辑模式，:wq保存

通过cat /etc/sudoers,可以查看修改后的文件内容

[root@localhost ~]# cat /etc/sudoers

将权限再修改回来

[root@localhost ~]# chmod -v u-w /etc/sudoers
mode of `/etc/sudoers' changed to 0440 (r--r-----)

普通用户创建完毕，可以进行用户切换

[root@localhost ~]# su dadi
