Nginx + 阿里雲SSL + tomcat 實現https訪問代理

第一步：阿里雲申請雲盾證書服務

第二步：下載證書

第三步：修改Nginx配置

1. 證書文件214033834890360.pem，包含兩段內容，請不要刪除任何一段內容。

2. 如果是證書系統創建的CSR，還包含：證書私鑰文件214033834890360.key。

( 1 ) 在Nginx的安裝目錄下創建cert目錄，並且將下載的全部文件拷貝到cert目錄中。如果申請證書時是自己創建的CSR文件，請將對應的私鑰文件放到cert目錄下並且命名為214033834890360.key；

( 2 ) 打開 Nginx 安裝目錄下 conf 目錄中的 nginx.conf 文件，找到：

修改Tomcat配置

新增配置項：
<Valve className="org.apache.catalina.valves.RemoteIpValve" remoteIpHeader="X-Forwarded-For"
protocolHeader="X-Forwarded-Proto" protocolHeaderHttpsValue="https"/>

第四步：啟動Nginx

/usr/local/nginx/nginx

第五步：測試https域名
