linux下通过进程名查看其占用端口

1、先查看进程pid

ps -ef | grep 进程名

2、通过pid查看占用端口

netstat -nap | grep 进程pid

例:通过nginx进程查看对应的端口号

#查看nginx进程pid:
命令:
ps -ef | grep nginx
结果:
root      9836     1  0 Jul11 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody    9841  9836  0 Jul11 ?        00:00:09 nginx: worker process      

#通过nginx进程pid查看占用端口(进程pid为9836)
命令:
netstat -nap | grep 9836
结果:
tcp        0      0 0.0.0.0:8081                0.0.0.0:*                   LISTEN      9836/nginx          
tcp        0      0 0.0.0.0:81                  0.0.0.0:*                   LISTEN      9836/nginx          
tcp        0      0 0.0.0.0:8082                0.0.0.0:*                   LISTEN      9836/nginx          
tcp        0      0 0.0.0.0:8083                0.0.0.0:*                   LISTEN      9836/nginx
