Nginx轉發多個二級域名及前後端分離

一、直接上程式碼（以下配置方案為親在廣州某物聯網公司做架構時的配置）

/etc/nginx/conf.d/ssl.conf 配置檔案：

其中sink-node1與web-node1為內部伺服器的hostname。

#

# HTTPS server configuration

    listen 443;

    server_name localhost;

  # subproject為其中一個子系統(前後端分離)的二級域名轉發配置

    error_page 404 /404.html;

        location = /50x.html {

    }

}

/etc/nginx/conf.d/static.conf 配置檔案：

其中58888埠專為 子系統subproject開放的靜態資源埠，其實就是代替nodejs的web服務。

#

# 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 {

    }

}
