一 访问linux的nginx
1.1 描述
在windows的系统中访问linux的nginx，默认是不能访问的，原因在于防火墙。解决办法
1.关闭防火墙；
2.开启防火墙，在防火墙中设置指定对外访问的端口。
查看端口：firewall-cmd --list-all
设置开放端口：
firewall-cmd --add-service=http --permanent
firewall-cmd --add-port=80/tcp --permanent
重启防火墙：
firewall-cmd --reload
二 查看防火墙端口
2.1 查看防火墙状态
[root@localhost ~]#systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Docs: man:firewalld(1)
[root@localhost ~]# pwd
2.2 开启防火墙
[root@localhost sbin]# systemctl start firewalld
[root@localhost sbin]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: active (running) since Thu -05-06 19:00:49 CST; 35min ago
Docs: man:firewalld(1)
Main PID: 2904 (firewalld)

2.3 查看端口
[root@localhost sbin]#firewall-cmd --list-all
public (active)
target: default

interfaces: ens33
sources:
services: ssh dhcpv6-client

2.4 开启制定端口
[root@localhost sbin]#firewall-cmd --add-service=http --permanent success
[root@localhost sbin]#firewall-cmd --add-port=80/tcp --permanent
success
1.5 重启防火墙
[root@localhost sbin]#firewall-cmd --reload
success
[root@localhost sbin]#firewall-cmd --list-all
public (active)
target: default
icmp-block-inversion: no
