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 :1New 'testdb:1 (root)' desktop is testdb:1Starting applications specified in /root/.vnc/xstartupLog file is /root/.vnc/testdb:1.log2）手工杀掉已经启动的VNC服务进程[root@testdb ~]# ps -ef | grep -i vnc | grep -v greproot      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 -pnroot      1182     1  0 11:07 pts/2    00:00:00 vncconfig -iconic[root@testdb ~]# kill -9 11783）确认进程已经杀掉[root@testdb ~]# ps -ef | grep -i vnc | grep -v grep4）再次启动桌面1的VNC服务，这里可以看到报错[root@testdb ~]# vncserver :1Warning: testdb:1 is taken because of /tmp/.X1-lockRemove this file if there is no X server testdb:1A VNC server is already running as :12.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 :1Warning: testdb:1 is taken because of /tmp/.X11-unix/X1Remove this file if there is no X server testdb:1A 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 :1New 'testdb:1 (root)' desktop is testdb:1Starting applications specified in /root/.vnc/xstartupLog file is /root/.vnc/testdb:1.log3.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-- The End --
