Centos上VNC 启动和关闭 常见问题汇总

1. 重设密码

[root@yqrh5u2 ~]# vncpasswd

Password:

Verify:

[root@yqrh5u2 ~]#

2. 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



3. 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

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 ~]# vncserver :1

Warning: yqrh5u2:1 is taken because of /tmp/.X1-lock

Remove this file if there is no X server yqrh5u2:1

A VNC server is already running as :1

[root@yqrh5u2 ~]# rm -f /tmp/.X1-lock

[root@yqrh5u2 ~]# vncserver :1
