linux检查删除端口

剖析:netstat -an检查到除夜量的80端口历程僵去世,重启tomcat.tomcat启动失落败,网页仍然无法翻开.

连气儿tomcat历程shutdown.sh，连气儿tomcat后telnet 127.0.0.1 80,发明80端口仍然可用。netstat -an|grep 80 检查发明有很多80端口历程在内里，运用kill pid敕令连气儿历程，无用。运用lsof -i :80|grep -v "PID"|awk '{print "kill -9",$2}'敕令后全部80端口历程删除。从新启动tomcat，体系正常运转。不外为什么tomcat在关闭时却不能将80端口的历程一并关闭的启事必要剖析一下。

以上脚本可以扫除80端口的历程 v
