linux查察删除端口

阐明:netstat -an查察到多量的80端口历程僵去世,重启tomcat.tomcat启动失败,网页仍然无法翻开.

中止tomcat历程shutdown.sh，中止tomcat后telnet 127.0.0.1 80,发明80端口仍然可用。netstat -an|grep 80 查察发明有许多80端口历程在内里，运用kill pid号令中止历程，无用。运用lsof -i :80|grep -v "PID"|awk '{print "kill -9",$2}'号令后通通80端口历程删除。重新启动tomcat，体系正常运转。不外为什么tomcat在封闭时却不克不及将80端口的历程一并封闭的缘由需求阐明一下。

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

以上剧本可以打扫80端口的历程 v
