系统/主机名	IP地址	服务
Redhat8 ：server1	192.168.244.131	nginx
Redhat8：server2	192.168.244.133	lnmp
Content7：node3	192.168.244.142	httpd

在server1上部署nginx

[root@server1 opt]# cat nginx.sh 
#!/bin/bash
if [ $UID -ne 0 ];then
        echo "Please use administrator accou

查看端口

[root@server1 ~]# ss -antl
State    Recv-Q   Send-Q       Local Address:Port                     Peer Address:Port                 
LISTEN   0        128                0.0.0.0:220.0.0.0:*
