linux中根据端口号开查找PID

[root@localhost huage]# netstat -anp |grep 111tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1415/rpcbind tcp 0 0 :::111 :::* LISTEN 1415/rpcbind udp 0 0 0.0.0.0:111 0.0.0.0:* 1415/rpcbind udp 0 0 :::111 :::* 1415/rpcbind




netstat：-a 显示全部-a, --all Show both listening and non-listening sockets. With the --interfaces option, show interfaces that are not marked
-n 显示端口号而不是名称 --numeric , -n Show numerical addresses instead of trying to determine symbolic host, port or user names.
-p 显示相关进程的PID及程序-p, --program Show the PID and name of the program to which each socket belongs.
-t 显示已经建立的连接
[root@1-min test]# netstat -nptActive Internet connections (w/o servers)Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 52 192.168.18.129:22 192.168.18.1:52826 ESTABLISHED 1628/sshd: huage [p tcp 0 0 192.168.18.129:22 192.168.18.1:52422 ESTABLISHED 1575/sshd: huage [p tcp 0 0 192.168.18.129:2049 192.168.18.136:697 ESTABLISHED - tcp 0 0 192.168.18.129:22 192.168.18.1:51551 ESTABLISHED 1532/sshd: huage [p

根据端口号来查询PID之二：[root@localhost huage]# lsof -i:111 //冒号后接的是端口号COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAMErpcbind 1415 rpc 6u IPv4 11465 0t0 UDP *:sunrpc rpcbind 1415 rpc 8u IPv4 11470 0t0 TCP *:sunrpc (LISTEN)rpcbind 1415 rpc 9u IPv6 11472 0t0 UDP *:sunrpc rpcbind 1415 rpc 11u IPv6 11475 0t0 TCP *:sunrpc (LISTEN)
