【实验】【VNC】手工kill掉VNC进程的故障处理

1.模拟Kill掉已经启动的VNC服务

1）启动桌面1的服务

[root@testdb ~]# vncserver :1

New 'testdb:1 (root)' desktop is testdb:1

Starting applications specified in /root/.vnc/xstartup

Log file is /root/.vnc/testdb:1.log

2）手工杀掉已经启动的VNC服务进程

[root@testdb ~]# ps -ef | grep -i vnc | grep -v grep

root 1178 1 0 11:07 pts/2 00:00:00 Xvnc :1 -desktop testdb:1 (root) -httpd /usr/share/vnc/classes -auth /root/.Xauthority -geometry 1024x768 -depth 16 -rfbwait 30000 -rfbauth /root/.vnc/passwd -rfbport 5901
-pn

root 1182 1 0 11:07 pts/2 00:00:00 vncconfig -iconic

[root@testdb ~]# kill -9 1178

3）确认进程已经杀掉

[root@testdb ~]# ps -ef | grep -i vnc | grep -v grep

4）再次启动桌面1的VNC服务，这里可以看到报错

[root@testdb ~]# vncserver :1

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

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

A VNC server is already running as :1

2.处理过程

很简单，按照错误提示的内容，需要删除/tmp/.X1-lock文件

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

启动尝试，仍然报错

[root@testdb ~]# vncserver :1

Warning: testdb:1 is taken because of /tmp/.X11-unix/X1

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

A VNC server is already running as :1

同样，按照提示的错误，进一步删除/tmp/.X11-unix/X1文件

[root@testdb ~]# rm -f /tmp/.X11-unix/X1

再次启动尝试，OK，启动成功！

[root@testdb ~]# vncserver :1

New 'testdb:1 (root)' desktop is testdb:1

Starting applications specified in /root/.vnc/xstartup

Log file is /root/.vnc/testdb:1.log

3.问题处理经验总结

再一次证明，解决技术问题的关键有

1）直面问题，充满信心，喜欢解决问题，即使时间紧任务重

2）远离浮躁

3）认真分析报错信息，寻找突破点

4）last but not least 向最好的老师Google请教
