1，启动和kill  vncserver

 [root@yqrh5u2 ~]# vncserver :1
  New ‘yqrh5u2:1 (root)‘ desktop is yqrh5u2:1
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/yqrh5u2:1.log
[root@yqrh5u2 ~]# vncserver :2
New ‘yqrh5u2:2 (root)‘ desktop is yqrh5u2:2
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/yqrh5u2:2.log
[root@yqrh5u2 ~]# ps -ef|grep -i vnc
root     12572     1  0 02:23 pts/2    00:00:00 Xvnc :1 -desktop yqrh5u2:1 (root) -httpd /usr/share/vnc/classes -auth /root/.Xauthority -geometry 1024x768 -depth 16 -rfbwait 30000 -rfbauth /root/.vnc/passwd -rfbport 5901 -pn
root     12580     1  0 02:23 pts/2    00:00:00 vncconfig -iconic
root     12617     1  0 02:23 pts/2    00:00:00 Xvnc :2 -desktop yqrh5u2:2 (root) -httpd /usr/share/vnc/classes -auth /root/.Xauthority -geometry 1024x768 -depth 16 -rfbwait 30000 -rfbauth /root/.vnc/passwd -rfbport 5902 -pn
root     12625     1  0 02:23 pts/2    00:00:00 vncconfig -iconic
root     12735 12536  0 02:24 pts/2    00:00:00 grep -i vnc

手动kill ：1， ：1的pid是12572，并验证：1确实已经被kill

[root@yqrh5u2 ~]# kill -9 12572
[root@yqrh5u2 ~]# ps -ef|grep -i vnc
root     12617     1  0 02:23 pts/2    00:00:00 Xvnc :2 -desktop yqrh5u2:2 (root) -httpd /usr/share/vnc/classes -auth /root/.Xauthority -geometry 1024x768 -depth 16 -rfbwait 30000 -rfbauth /root/.vnc/passwd -rfbport 5902 -pn
root     12625     1  0 02:23 pts/2    00:00:00 vncconfig -iconic
root     12779 12536  0 02:25 pts/2    00:00:00 grep -i vnc

通过vncserver kill ：1，：2，这是最好的方法，推荐使用

[root@yqrh5u2 ~]# vncserver -kill :1
Killing Xvnc process ID 12572
kill 12572: No such process
[root@yqrh5u2 ~]# vncserver -kill :2
Killing Xvnc process ID 12617
[root@yqrh5u2 ~]# ls /root/.vnc/
passwd  xstartup  yqrh5u2:1.log  yqrh5u2:2.log

2，重新启动一个手动kill的vncserver，

    因为是手动自己删除的，所以要再删除一下被lock的文件，才可以重新启动，如图所示

   [root@yqrh5u2 ~]# vncserver
