Linux 占用端口查看

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>>

1、使用netstat -tunlp查看全部端口

[root@develop bin]# netstat -tunlp

Active Internet connections (only servers)

udp 0 0 :::123 :::* 1911/ntpd

2、查看某一端口的占用情况： lsof -i:端口号或者netstat -tlnp|grep 端口号

[root@develop bin]# lsof -i:8080

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

java 21650 rptadm 46u IPv6 495647 0t0 TCP *:webcache (LISTEN)

[root@develop bin]# netstat -tlnp|grep 8080

tcp 0 0 :::8080 :::* LISTEN 21650/java
