nginx+tomcat配置https最简单方案

1.申请https证书
https的证书在阿里云现在可以免费申请，最多一个服务器可以申请15个。
申请下来后可以在阿里云的后台，下载到 215080384110964.key 215080384110964.pem
2.配置nginx

#user  nobody;
worker_processes  1;
#pid        logs/nginx.pid;
events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
        client_max_body_size 20m;
    #access_log  logs/access.log  main;
    sendfile        on;
    #gzip  on;

server{
        listen 80;
        listen 443 default ssl;

		root /www/server/apache-tomcat-8.5.32/webapps/ROOT/;
		location ~ .*.(ico|png|gif|jpg|jpeg|png|bmp|swf|css|js|html)$ {
                expires 30d;
        }
        ssl_certificate ssl_tb/215080384110964.pem;
        ssl_certificate_key ssl_tb/215080384110964.key;
        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;

        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers  on;

        server_name app.guanzistory.com;
                location =/
        {
        rewrite / /i;
        }
        location / {
                        root   html;
                        index  index.html index.htm;
                        proxy_pass http://127.0.0.1:8080/;
                        proxy_set_header Host $host;
                        proxy_set_header X-Real-IP $remote_addr;
                        proxy_set_header REMOTE-HOST $remote_addr;
                        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                        proxy_set_header           X-Forwarded-Proto https;
        }
        }

}

3.完成

listen 80;
listen 443 default ssl;

nginx可以监听两个端口，同时监听80和443

ssl_certificate ssl_tb/215080384110964.pem;
        ssl_certificate_key ssl_tb/215080384110964.key;
        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;

        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers  on;

ssl的配置，主要是以上部分

proxy_set_header           X-Forwarded-Proto https;

以上配置，实现了在nginx端的https解密，到了tomcat端，就不用处理了。
