nginx.conf 配置

在同级目录下 新建domains文件夹

比如botucarecn.conf 配置如下 其他配置大致相同 想多个域名 配置类似下 只是指向的服务器地址不同，nginx会根据匹配的域名来进行ip的转发

upstream botucare {
        server 10.1.2.249  weight=10 max_fails=2 fail_timeout=30s;
}

server {
     listen 80;
     server_name www.xxx.com;
     proxy_set_header Host $host;
     proxy_set_header X-Real-IP $remote_addr;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     location  / {
                  proxy_pass http://botucare;
                }
  }

其他实用配置：

server {
        listen       80;
        server_name  xxx.com;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   /hanhao/nginx/web/okexhb;
            index  index.html index.htm;
        }

include domains/*.conf;

upstream mgr {
          session_sticky;
                server 10.1.24.111:9090;
                server 10.1.24.111:8080;
    }

server {
     listen 8989;
     server_name 10.1.24.111;
     proxy_set_header Host $host;
     proxy_set_header X-Real-IP $remote_addr;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     location  / {
                  proxy_pass http://mgr;
                }
     location /status {
                 deny all;
                }

     location /dyn {
                 deny all;
                }

    }
