Linux下查看連接埠佔用情況

Linux下查看連接埠佔用情況 用啟動服務的帳號登入，然後運行命令：lsof -i:<連接埠號碼>例如：www.2cto.com  Linux代碼  [root@SonarServer1 user0]# lsof -i:80  COMMAND   PID USER   FD   TYPE    DEVICE SIZE/OFF NODE NAME  java    19408 root  144u  IPv6 183572842      0t0  TCP *:http (LISTEN)     www.2cto.com  也可使用命令：netstat -apn|grep <連接埠號碼>例如：Linux代碼  [root@SonarServer1 user0]# netstat -apn|grep 80  tcp        0      0 :::80                       :::*                        LISTEN      19408/java     找到進程號以後，再使用以下命令查看詳細資料：ps -aux|grep <進程號>Linux代碼  [root@SonarServer1 user0]# ps -aux|grep 19408  Warning: bad syntax, perhaps a bogus '-'?
