最近在工作當中需要使用nginx，就對nginx進行進一步的瞭解，測試。

       工作需求是在微服務架構的基礎上，客戶端通過nginx反向代理訪問服務端，確保當一個服務端出現問題時能及時切換到正常工作的服務端。測試使用nginx-1.13.2.rar，官網地址為：http://www.nginx.org/;測試使用的ip服務端為:10.74.214.109:8088、10.74.214.109:8091，服務端啟動時的埠為8090;程式首頁的路徑為:"D:\cloudCode\internet\CoreToolWebPortal\01.CoreToolWebPotalWeb"下的index.html檔案
  將nginx解壓包放在C盤根目錄下:
  編輯修改nginx.conf檔案，如下:
 
  #Nginx使用者組。windows下不指定;
  #user  nobody;
 
     #工作程序:數目。根據硬體調整，通常等於CPU數量，或者2倍於CPU;
     worker_processes  1;
 
     #pid        logs/nginx.pid;
 
 
   events {
        #每個工作程序的最大連線數量，根據硬體調整，和前面工作程序配合起來使用，儘量大，
        #但是別把CPU跑到100%就行。
        #每個程序允許的最多連線數，理論上沒臺nginx伺服器的最大連線數       
        #為:worker_process*worker_connections
       worker_connections  1024;
       }
