无法通过 http 访问 nginx CentOS 7

Question

在vps上配置了nginx，但是通过http访问公网ip或者域名默认的index.html是访问不到的

nginx 配置

server {
    listen       80 default_server;
    server_name  domainname.com;
    root   /usr/share/nginx/html;
    index  index.html;

    location / {
    }
}

Answer 1

默认情况下centos 7防火墙是屏蔽端口80

需要编辑下一个文件

/etc/firewalld/zones/public.xml

添加80端口

<?xml version="1.0" encoding="utf-8"?>
<zone>
  <short>Public</short>
  <description>For use in public areas. You do not trust the other computers on networks to not harm your computer. Only selected incoming connections are accepted.</description>
  <service name="ssh"/>
  <service name="dhcpv6-client"/>
  <port protocol="tcp" port="80"/>
</zone>

重新加载防火墙

firewall-cmd --reload
