Nginx 配置反向代理

upstream monitor_server {<span style="white-space:pre">	</span>#这里是为了使用负载均衡，使得多个ip可以提供同一个服务，weight为权值，
    server 10.10.12.203:8080 weight=2;
    server 10.10.12.202:8080 weight=4;
}

server 
{
    listen 8081;
    server_name www.xxx123.com;<span style="white-space:pre">	</span># 反向域名代理，不同的域名是指向同一入口ip，经过nginx，又转向不同的内部ip提供网络服务，"www"不省略
    location / {
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://monitor_server;
    }
}

server 
{
    listen 8081;
    server_name localhost;
    location / {
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://10.10.12.203:8080;
    }
}
