linux如何查看端口被谁占用

linux如何查看端口被谁占用

使用 netstat 进行查看！ >netstat -noap | grep 80 | grep tcp Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name ----------------------------------------------------------------------------------------------------------------- tcp 74160 138880 127.0.0.1:6150 127.0.0.1:6150 ESTABLISHED 3145/tnslsnr unkn-4 (52.04/0/0) tcp 0 0 :::8009 :::* LISTEN 31550/java off (0.00/0/0) tcp 0 0 :::8080 :::* LISTEN 31550/java off (0.00/0/0) tcp 0 0 :::80 :::* LISTEN 24675/httpd off (0.00/0/0)


使用 lsof 进行查看！ 谁在使用tcp8080端口 lsof -i tcp:8080 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME ------------------------------------------------------ java 31550 root 109u IPv6 78687600 TCP *:webcache (LISTEN) 谁在使用22端口 lsof -i :22 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME sshd 2883 root 3u IPv6 7642 TCP *:ssh (LISTEN)


然后根据 pid
使用ps -ef | grep pid去查是哪里占用了
