【linux】tomcat网站无法访问80端口被占用解决方法

故障:网站无法访问

分析:netstat -an查看到大量的80端口进程僵死,重启tomcat.tomcat启动失败,网页依然无法打开.

停止tomcat进程shutdown.sh，停止tomcat后telnet 127.0.0.1 80,发现80端口依然可用。netstat -an|grep 80 查看发现有许多80端口进程在里面，使用kill pid命令终止进程，无用。使用lsof -i :80|grep -v "PID"|awk '{print "kill -9",$2}'命令后所有80端口进程删除。重新启动tomcat，系统正常运行。不过为什么tomcat在关闭时却不能将80端口的进程一并关闭的原因需要分析一下。

[root@gzcourt bin]# netstat -an |grep 80

以上脚本可以清除80端口的进程
