一、Linux賬號空閒登出(Idel logout)

  1. vi /etc/profile 新增：

  3. export TMOUT=900



二、sudo命令使用

編輯/etc/sudoers檔案，按照示例root的格式，新增相應賬號

  1. [root@TaylonMeng ~]# visudo 或 vi /etc/sudoers

  3. ## Allow root to run any commands anywhere
  4. root ALL=(ALL) ALL
  5. oracle ALL=(ALL) ALL
-u：後接欲切換的使用者，若不加，則為root

  1. [oracle@TaylonMeng ~]$ more /etc/shadow
  2. /etc/shadow: Permission denied
  3. [oracle@TaylonMeng ~]$ sudo -u root more /etc/shadow

  5. We trust you have received the usual lecture from the local System
  6. Administrator. It usually boils down to these three things:

  8.     #1) Respect the privacy of others.
  9.     #2) Think before you type.
  10.     #3) With great power comes great responsibility.

  12. [sudo] password for oracle:
  13. root:$6$fwjcKvgG$pX73atu/RvAiXaYv1QWh4Y6QSFaMROAvbQXKkeLHjvVL6lnY7FPYuEAC3ASHCuH
  14. nFReg4lgrzOLXwRWxlSWNV0:16936:0:99999:7:::

  18. lp:*:15937:0:99999:7:::
