1.查看监听端口：

[root@bogon ~]# stat.html' target='_blank'>netstat -ntul |grep LISTEN

[root@bogon ~]# netstat -ntul |grep LISTEN 
tcp        0      0 127.0.0.1:2208              0.0.0.0:*                   LISTEN       
tcp        0      0 0.0.0.0:808                 0.0.0.0:*                   LISTEN       
tcp        0      0 0.0.0.0:3306                0.0.0.0:*                   LISTEN       
tcp        0      0 0.0.0.0:111                 0.0.0.0:*                   LISTEN       
tcp        0      0 0.0.0.0:22                  0.0.0.0:*                   LISTEN       
tcp        0      0 127.0.0.1:631               0.0.0.0:*                   LISTEN       
tcp        0      0 127.0.0.1:25                0.0.0.0:*                   LISTEN       
tcp        0      0 127.0.0.1:2207              0.0.0.0:*                   LISTEN 

2.查看端口及服务

[root@bogon ~]# netstat -ntupl |grep LISTEN

[root@bogon ~]# netstat -ntupl |grep LISTEN 
tcp        0      0 127.0.0.1:2208              0.0.0.0:*                   LISTEN      2973/hpiod
