The following problem occurred during the use of su command in Centos: "cannot open session: Permiss

centos su - 使用者名 su: cannot open session: Permission denied

剛才用文章CentOS建立sudo使用者建立了一個賬号lwk，然後用

su - lwk

指令的時候報錯了。

-bash-4.2$ su - lwk

There was 1 failed login attempt since the last successful login.
su: cannot open session: Permission denied
-bash-4.2$
           

經多方查找，終于解決了通路題。解決思路如下：

編輯檔案/etc/security/limits.conf，在檔案末尾追加如下内容：

lwk soft nofile 65535
lwk hard nofile 65535
           

其中，lwk是打算用

su - lwk

指令進行切換使用者的使用者名。
