nginx反向代理本地 两台web负载均衡 使用域名代理

环境：

本地外网ip：123.58.251.166

、配置index.html网页

[root@host---- conf.d]# cat /web/sing/index.html
<h1>www.test1.com</h1>
[root@host---- conf.d]# cat /root/html/index.html
<h1>www.test2.com</h1>

、配置conf.d目录下配置文件

[root@host---- conf.d]# pwd
/etc/nginx/conf.d
[root@host---- conf.d]# ls
test1.conf  test2.conf  test3.conf
[root@host---- conf.d]# cat test1.conf
server {
listen ;
server_name 127.0.0.1:;
location / {
root /web/sing/;
index index.html index.htm;
}
}

[root@host---- conf.d]# cat test2.conf
server {
listen ;
server_name 127.0.0.1:;
location / {
root /root/html/;
index index.html index.htm;
}
}

[root@host---- conf.d]# cat test3.conf
upstream abc.com {
        server 127.0.0.1: fail_timeout=20s;
        server 127.0.0.1: fail_timeout=20s;

        #ip_hash; 打开后就会访问到一台上

}

server {

        listen       ;
        server_name  oa.test.com;
        location / {
             #反向代理的地址
             proxy_pass http://abc.com;
        }
}

、配置hosts

[root@host---- conf.d]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::         localhost localhost.localdomain localhost6 localhost6.localdomain6
123.58.251.166 oa.test.com 

[root@host---- conf.d]# nginx -s reload

、开始访问     

注意：要从百度访问必须注册备案域名

[root@host---- ~]# curl http://oa.test.com
<h1>www.test1.com</h1>
[root@host---- ~]# curl http://oa.test.com
