【Tomcat】-- Tomcat + Nginx反向代理https和wss并解决获取客户端真实IP、域名、协议、端口

刚开始只做了http和ws，由于做小程序必须要https和wss，无奈将服务器http进行https转换，ws做wss转换。

首先我们得申请https证书，请参考前面的博客。

第二全站https和wss化：

以下是我的配置(tomcat已经支持https端口8999，websocket由单独的tomcat提供端口为10000)：

server
    {
        listen 80;
        #listen [::]:80;
        server_name xxx.com;
        #ws代理
         location /webtcpnode/
        {
             proxy_pass http://127.0.0.1:10000;
             proxy_set_header X-Real-IP $remote_addr;
             proxy_set_header Host $host;
             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
             proxy_set_header X-Forward-For $remote_addr;
             proxy_set_header X-Forwarded-Proto $scheme;
             proxy_redirect off;
             proxy_http_version 1.1;
             proxy_set_header Upgrade $http_upgrade;
             proxy_set_header Connection "upgrade";
        }
        #http强制https的两种方式
        #rewrite ^(.*)$  https://$host$1 permanent;①
        location / {②
             rewrite ^/(.*) https://$host/$1 redirect;
        }
        access_log  /home/wwwlogs/xxx.log  access;
    }
server
    {
        listen 443;
        #listen [::]:80;
        server_name dev.smart-ism.com;
        index index.html index.htm index.php default.html default.htm default.php;
        root  /home/wwwroot/xxx.com;
        ssl on;
        ssl_certificate   cert/214214075370856.pem;
        ssl_certificate_key  cert/214214075370856.key;
        ssl_session_timeout 5m;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;
        location /
        {
             proxy_pass https://127.0.0.1:8999;
             proxy_next_upstream error timeout invalid_header http_500 http_502 http_503;
             proxy_set_header Host $host;
             proxy_set_header X-Real-IP $remote_addr;
             proxy_set_header X-Forward-For $remote_addr;
             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
             proxy_set_header X-Forwarded-Proto $scheme;
             proxy_redirect     off;
             #include proxy-totomcat.conf;
        }
	#wss代理
        location /webtcpnode/
        {
             proxy_pass http://127.0.0.1:10000;
             proxy_set_header X-Real-IP $remote_addr;
             proxy_set_header Host $host;
             proxy_set_header X-Forward-For $remote_addr;
             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
             proxy_set_header X-Forwarded-Proto $scheme;
             proxy_http_version 1.1;
             proxy_set_header Upgrade $http_upgrade;
             proxy_set_header Connection "upgrade";
             #rewrite /webtcpnode/(.*) /$1 break;
             proxy_redirect off;
        }

        #location /
        #{
        #    try_files $uri @apache;
        #}

        #location @apache
        #{
        #    internal;
        #    proxy_pass http://127.0.0.1:88;
        #    include proxy.conf;
        #}

        #location ~ [^/]\.php(/|$)
        #{
        #    proxy_pass http://127.0.0.1:88;
        #    include proxy.conf;
        #}

        #location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
        #{
        #    expires      30d;
        #}

        #location ~ .*\.(js|css)?$
        #{
        #    expires      12h;
        #}

        access_log  /home/wwwlogs/xxx.com.log  access;
    }

第三修改tomcat获取代理前的客户端信息方式

具体文档：http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/catalina/valves/RemoteIpValve.html

配置：tomcat的server.xml

Nginx增加以下配置 
proxy_set_header Host $host:$server_port; 非80端口 ，用80端口时 不需要$server_port 
proxy_set_header X-Real-IP $remote_addr; 非必须，添加此项之后可以在代码中通过request.getHeader("X-Real-IP")获取ip
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
proxy_set_header X-Forwarded-Proto $scheme; 

Tomcat server.xml配置  重点在这里！
 
 非80端口时，必须增加httpsServerPort配置，不然request.getServerPort()方法返回 443.
