0, 重设密码

\[root@yqrh5u2 ~\]\# vncpasswd  
          Password:  
          Verify:  
        \[root@yqrh5u2 ~\]\#

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  
  
Warning: yqrh5u2:1 is taken because of /tmp/.X1-lock  
Remove this file if there is no X server yqrh5u2:1
