nginx基本配置

 1 worker_processes  2;
 2 events {
 3     worker_connections  1024;
 4 }
 5 http {

 7     default_type  application/octet-stream;
 8     #upstream配置被代理的服务器，localServer为自定义的服务器别名
 9     upstream localServer{
10         server 127.0.0.1:9002;
11     }
12     server {
13         listen       80;
14         server_name  localhost;
15         <!-- 以/api/开头的url都被此location拦截-->
16         location ^~ /api/ {
17             proxy_set_header Host $http_host;
18             proxy_set_header X-Real-Ip $remote_addr;
19             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
20             proxy_set_header X-Forworded-For $http_x_forwarded_for;
21             proxy_pass  http://localServer;
22             #root   html;
23             #index  index.html index.htm;
24         }
25         <!-- 默认访问到html目录下的静态资源-->
26         location / {
27             root   html;
28             index  index.html index.htm;

32             root   html;
33         }
34     }
35 }

ip_hash负载均衡策略配置：
upstream lagouServer{
   ip_hash;
   server 127.0.0.1:8080;
   server 127.0.0.1:8082;
}
权重策略配置：
upstream lagouServer{
   server 127.0.0.1:8080 weight=1;
   server 127.0.0.1:8082 weight=2;
}
