编辑nginx.conf

nginx实现负载均衡

upstream nodejs {
    server 127.0.0.1:8091;
    server 127.0.0.1:3001;
    server 47.x.x.x:3000;
    keepalive 64;
}

server {
    listen 80;
    server_name xxx.com;
    access_log logs/node.test.log;
    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host  $http_host;
        proxy_set_header X-Nginx-Proxy true;
        proxy_set_header Connection "";
        proxy_pass      http://nodejs;

    }

}

反向代理

server {
    listen 80;
    server_name aaa.com;
   server_name bbb.com;
   server_name ccc.com;
    access_log logs/node.test.log;
    location ^~ /aaa{
        proxy_pass      http://aaa.com;
    }
    location ^~ /bbb{
        proxy_pass      http://bbb.com;
    }
   location ^~ /ccc{
        proxy_pass      http://ccc.com;
    }

}
