环境说明
系统OS：CentOS7
IP: 192.168.1.7
配置过程
- 创建 /etc/yum.repos.d/nginx.repo 文件，向里面添加内容：
# vi /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
执行yum安装
# yum install nginx -y修改nginx配置文件，添加域名映射。
# vi /etc/nginx/nginx.conf

}
}
server{
listen 80;
server_name spis.dimonho.com; #将域名spis.dimonho.com映射到192.168.1.101的18080端口
location / {

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 100m;
}
}
}
设置开机启动nginx服务
# systemctl enable nginx启动nginx服务
# systemctl start nginx设置防火墙允许80端口访问
# firewall-cmd --add-port=80/tcp --permanent
路由器NAT映射
- 访问192.168.1.1
- 路由器登陆：admin/admin123
-
虚拟NAT转发，添加NAT端口映射
NAT
配置域名解析
-
查看自己的公网IP
公网IP -
注册一个域名，添加域名解析
域名解析 当访问 http://cas.dimonho.com 或 http://spis.dimonho.com 时，DNS服务器解析该域名找到IP 175.8.210.184， http://175.8.210.184:80 通过路由器NAT转发到 http://192.168.1.7:80 请求nginx服务，由nginx将 cas.dimonho.com 和 spis.dimonho.com 分别解析为请求内部的 http://192.168.1.101:8080 和http://192.168.1.101:18080 返回结果。
至此，一套完整的nginx服务流程才算完成。
