centos新增普通使用者流程

新增普通使用者

[[email protected] ~]# adduser dadi

密碼

[[email protected] ~]# passwd dadi

密碼設定過於簡單的話會有提示

先檢視許可權

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

修改許可權，增加寫許可權

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

新增新使用者

[[email protected] ~]# 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.

儲存修改的檔案，ESC 退出編輯模式，:wq儲存

通過cat /etc/sudoers,可以檢視修改後的檔案內容

[[email protected] ~]# cat /etc/sudoers

將許可權再修改回來

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

普通使用者建立完畢，可以進行使用者切換

[[email protected] ~]# su dadi
