nginx 负载均衡的三种参数设置

唐伯虎

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
