檢視最近使用者登入情況

[root@localhost ~]# last

oracle   pts/1        10.1.1.1         Thu Dec 23 08:59   still logged in

reboot   system boot  2.6.18-164.el5   Wed Dec 22 20:19          (12:59)

root     pts/1        10.1.1.2         Sun Dec 12 13:07 - 13:59  (00:52)

 

檢視作業系統的歷史命令：

[root@localhost ~]#history |more

  382  top

  383  df -lh

  384  top

  385  service iptables stop

  386  last

  387  last reboot

  388  last

  389  history

  390  history |more

 

在執行top命令時都可以檢視系統狀態，然後就出現了reboot重啟系統的狀況。在service iptables stop 命令之前沒有查下到reboot的命令，可見是系統重啟。

檢視系統的日子資訊：

[root@localhost ~]#cat /var/log/messages |more

後經確認，這是在機房人為重啟伺服器。
