Nginx转发多个二级域名及前后端分离

一、直接上代码（以下配置方案为亲在广州某物联网公司做架构时的配置）

/etc/nginx/conf.d/ssl.conf 配置文件：

其中sink-node1与web-node1为内部服务器的hostname。

#

# HTTPS server configuration

    listen 443;

    server_name localhost;

  # subproject为其中一个子系统(前后端分离)的二级域名转发配置

      set $eff_flag 'EFF';

  # 关键此，这专门使用nginx来处理前端分离的静态资源，而不是转发到nodejs/webpack服务

      # subproject static resource forwarding.

      if ($eff_flag ~* 'EFFF' ) {

        location = /50x.html {

}

/etc/nginx/conf.d/static.conf 配置文件：

其中58888端口专为 子系统subproject开放的静态资源端口，其实就是代替nodejs的web服务。

#

# HTTP front/static server configuration

server {

    # The port that is transferred to the front end and the end is not open to the external network.

    listen      58888;

    server_name  localhost;

    location / {

      # Fixed format (if additional front and back end separation items should be configured in this format),

      # both root and index instructions are necessary, because the static file of the project will be under

      # the directory of the root instruction, otherwise it will not be loaded..

      root /usr/share/nginx/html/efficiency-front;

      index index.html;

    }

    error_page 404 /404.html;

        location = /40x.html {

    }

    error_page 500 502 503 504 /50x.html;

        location = /50x.html {

    }

}
