node-nginx二级域名添加配置

首先在阿里云配置解析域名

指向端口为3200的nodejs服务，在nginx/conf.d下增加文件chat.conf，内容如下：

server {
    listen 80;

    server_name www.chat.sanjiadian.net chat.sanjiadian.net;

    location / {
             proxy_pass http://127.0.0.1:3200;
             proxy_http_version 1.1;
             proxy_set_header Upgrade $http_upgrade;
             proxy_set_header Connection 'upgrade';
             proxy_set_header Host $host;
             proxy_cache_bypass $http_upgrade;
   }
}
注意nginx/nginx.conf文件中的http下包含：include /etc/nginx/conf.d/*.conf;实际根据自己的nginx安装目录

重启nginx
