nginx 负载均衡的三种参数设置

1、

user nobody;
worker_processes 4;//一般是cpu的核心数
events{
  worker_connections 1024;
}

http{
  upstream mypro {
    server 182.13.32.12;
    server 213.11.23.24;
  }

  server {
    listen 8080;
    location / {
      proxy_pass http://mypro;
    }
  }
}

2、加入ip_hash,让同一个用户落到同一台机器上

use nobody;
worker_processes 4;//一般是cpu的核心数
events{
  worker_connections 1024;
}

http{
  upstream mypro {
    ip_hash;
    server 182.13.32.12;
    server 213.11.23.24;
  }

  server {
    listen 8080;
    location / {
      proxy_pass http://mypro;
    }
  }
}

3、加入权重

use nobody;
worker_processes 4;//一般是cpu的核心数
events{
  worker_connections 1024;
}

http{
  upstream mypro {
    server 182.13.32.12 weight=2;//被访问到的概率
    server 213.11.23.24;
  }

  server {
    listen 8080;
    location / {
      proxy_pass http://mypro;
    }
  }
}

负载均衡的进程可以单独启动
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/fzjh.conf
