1.模擬Kill掉已經啓動的VNC服務
1）啓動桌面1的服務[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）手工殺掉已經啓動的VNC服務進程
[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）確認進程已經殺掉
[root@testdb ~]# ps -ef | grep -i vnc | grep -v grep
4）再次啓動桌面1的VNC服務，這裏可以看到報錯
[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.處理過程
很簡單，按照錯誤提示的內容，需要刪除/tmp/.X1-lock文件
[root@testdb ~]# rm -f /tmp/.X1-lock
啓動嘗試，仍然報錯
[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
同樣，按照提示的錯誤，進一步刪除/tmp/.X11-unix/X1文件
[root@testdb ~]# rm -f /tmp/.X11-unix/X1
再次啓動嘗試，OK，啓動成功！
[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.問題處理經驗總結
再一次證明，解決技術問題的關鍵有
1）直面問題，充滿信心，喜歡解決問題，即使時間緊任務重
2）遠離浮躁
3）認真分析報錯信息，尋找突破點
4）last but not least 向最好的老師Google請教
