第一章 nginx 支持https 配置样例

  • 说明：https 段配置参数说明
Server 段::
listen 443 http2 spdy; #侦听443端口，并按照http2.0、spdy、http1.1 的顺序进行适用协议匹配，向下兼容。  
ssl on;   #开启ssl
ssl_certificate      ../ssl/58_com-key/server.pem; #指定证书位置（线下测试证书在ssl.tar包里，需要将tar包上传至linux服务器上解压，在子目录中选用一套证书及私钥使用，推荐使用58_com-key下的证书和私钥）
ssl_certificate_key  ../ssl/58_com-key/server.key; #指定证书私钥位置
ssl_session_timeout  10m;   # ssl session超时时间
ssl_protocols  TLSv1 TLSv1.1 TLSv1.2; #ssl 链路支持协议
ssl_ciphers  "ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DES-CBC3-SHA:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!MD5:!PSK:!RC4";  #ssl加密支持套件
ssl_prefer_server_ciphers   on;#优先匹配服务端加密套件

location 段：
proxy_set_header HTTPS-Tag  "HTTPS"; #设置HTTPS_TAG标识，方便程序认读
proxy_set_header X-Forwarded-Proto $scheme; #设置协议头传递变量

使用X-Forwarded-Proto进行协议的判定识别，需要在tomcat配置中添加内容：#使用X-Forwarded-Proto传递协议的条件是因为:在使用相对协议做跳转时，程序需要读取协议头再做跳转。而代理传递给后端的协议永远都是http协议，而真正的协议头https并没有传递成功。$scheme变量可以获取到用户访问使用的真正协议。将$scheme 变量赋值给 X-Forwarded_Proto 变量向后端（tomcat）传递协议可以避免这个问题。但是这时候tomcat使用X-Forwarded-For来获取用户IP可能存在问题。需要更换获取变量为X-Real-IP。 
Tomcat-server.xml配置：
在Engine段添加：

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

线上配置样例：

HTTP-80 段详细配置：

server {
        listen       80;
        server_name  example.58.com;
        access_log /opt/log/nginx/example.58.com/example.58.com_access.log main;
        error_log /opt/log/nginx/example.58.com/example.58.com_error.log error;
        charset utf-8;

        #### by dongange ####
        set $remote_address $http_x_forwarded_for;

        if ( $remote_address !~ "[0-9]" ) {
            set $remote_address $remote_addr;
        }
        #### ----------- ####

        location / {
                proxy_pass http://example_pool;
                proxy_set_header  Host  $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $remote_address;
                proxy_set_header HTTPS-Tag  "HTTP";
                proxy_set_header X-Forwarded-Proto $scheme;
        }
        error_page 404 = http://404.58.com/404.html?from=$host$request_uri;
}

HTTPS-443 段详细配置配置：

server {
        listen       443 http2 spdy;
        server_name  example.58.com;
        access_log /opt/log/nginx/example.58.com/example.58.com_https_access.log main;
        error_log /opt/log/nginx/example.58.com/example.58.com_https_error.log error;
        charset utf-8;

        ssl on;
        ssl_certificate     ../ssl/58_com-key/server.pem;
        ssl_certificate_key  ../ssl/58_com-key/server.key;
        ssl_session_timeout  10m;
        ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers "ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DES-CBC3-SHA:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!MD5:!PSK:!RC4";
        ssl_prefer_server_ciphers   on;

        #### by dongange ####
        set $remote_address $http_x_forwarded_for;

        if ( $remote_address !~ "[0-9]" ) {
            set $remote_address $remote_addr;
        }
        #### ----------- ####

        location / {
                proxy_pass http://example_pool;

                proxy_set_header X-Real-IP $remote_addr;

                proxy_set_header HTTPS-Tag  "HTTPS";
