年底了寫一篇小程式環境搭建的文章, 主要是怎麼搭建一個線上環境以及怎麼不改動原有http Api的情況

1、準備工作

 域名一個
 免費證書(推薦: 騰訊雲、阿里雲、便宜ssl 都是免費的 配置好後先將證書下載下來)
 Centos伺服器一臺
 nginx 1.10.2

2、 安裝nginx

  安裝教程 http://www.runoob.com/linux/nginx-install-setup.html
  注意安裝的時候 編譯 --with-stream --with-stream_ssl_module 兩個模組
  如果啟動nginx報錯看下圖解決

3、 配置nginx實現ssl反向代理

  將下載好的證書根據自己的伺服器選擇證書這裡選擇nginx證書
  主要用到server.crt以及server.key兩個證書上傳到伺服器
  這裡我們直接上傳到nginx目錄的conf下了

修改nginx.conf(有註釋的地方改 其他的保持原樣就行了)
