Linux用root强制踢掉已登录用户

首先使用w命令查看所有在线用户：

[root@VM_152_184_centos /]# w
 20:50:14 up 9 days,  5:58,  3 users,  load average: 0.21, 0.05, 0.02
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT
root     pts/0    101.45.224.253   20:48    0.00s  0.00s  0.00s w
root     pts/1    101.45.224.253   20:49   17.00s  0.00s  0.00s -bash
hmj      pts/2    101.45.224.253   20:50    2.00s  0.00s  0.00s -bash

执行命令：

pkill -kill -t TTY值

例：踢掉已登录用户hmj

pkill -kill -t pts/2

再用w命令查看是否已经强制踢掉：

[root@VM_152_184_centos /]# w
 20:55:10 up 9 days,  6:03,  2 users,  load average: 0.03, 0.03, 0.00
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT
root     pts/0    101.45.224.253   20:48    0.00s  0.00s  0.00s w
root     pts/1    101.45.224.253   20:49    5:13   0.00s  0.00s -bash
