Nginx + 阿里云SSL + tomcat 实现https访问代理

第一步：阿里云申请云盾证书服务

第二步：下载证书

第三步：修改Nginx配置

1. 证书文件214033834890360.pem，包含两段内容，请不要删除任何一段内容。

2. 如果是证书系统创建的CSR，还包含：证书私钥文件214033834890360.key。

( 1 ) 在Nginx的安装目录下创建cert目录，并且将下载的全部文件拷贝到cert目录中。如果申请证书时是自己创建的CSR文件，请将对应的私钥文件放到cert目录下并且命名为214033834890360.key；

( 2 ) 打开 Nginx 安装目录下 conf 目录中的 nginx.conf 文件，找到：

worker_processes ;
error_log logs/error.log crit; #日志位置和日志级别
pid logs/nginx.pid;
worker_rlimit_nofile ;
events {
worker_connections ;

}

}
}

修改Tomcat配置

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

第四步：启动Nginx

/usr/local/nginx/nginx

第五步：测试https域名
