具有SSL终止的Apache前向代理

问题描述 投票：6回答：1

我正在尝试设置一个终止SSL连接的Apache Forward Proxy。我试图这样做的原因是在返回的代码上运行Apache过滤器（特别是mod_pagespeed）。在我处理mod_pagespeed之前，我正在通过尝试在响应中插入一个标头来测试这个POC（这将证明我可以编辑响应），但我遇到了SSL代理问题（非SSL代理工作正常） 。

请注意，我并不担心任何证书错误等 - 这纯粹是为了内部测试。

我已经设置了服务器并在非SSL页面上看到了X-MSCProxy Header：

jshannon-macbookpro:pagespeed_proxy jshannon$ curl -vv --proxy pagespeed_proxy:3ja82ad9@localhost:8080 -D - -o /dev/null http://www.slate.com

* TCP_NODELAY set
* Connected to localhost (::1) port 8080 (#0)

但是当我向Slate的SSL页面发出相同的请求时，我看不到我的代理：

jshannon-macbookpro:pagespeed_proxy jshannon$ curl -vv --proxy pagespeed_proxy:3ja82ad9@localhost:8080 -D - -o /dev/null https://www.slate.com

我发现很多帖子都说这是可能的（而且，从技术上来说，它应该是）各种httpd.conf建议，但我尝试过的任何东西都没有用。现在我的httpd.conf看起来像：

<VirtualHost *:8080>
  ProxyRequests On
  ProxyVia On

  Header set X-MSCProxy SansPS

  #SSLEngine On
  # suggestion that this allows termination
  ProxyPreserveHost On

  SSLProxyEngine on
  SSLProxyCheckPeerCN Off
  SSLProxyCheckPeerExpire Off
  SSLProxyCheckPeerName Off

  SSLCertificateFile /etc/apache2/ssl/localhost.crt
  SSLCertificateKeyFile /etc/apache2/ssl/localhost.key

  ModPagespeed Off
</VirtualHost>

FWIW，当我在这个代理上启用SSLEngine时（如建议的那样），那么请求根本无法解决Apache的错误：

[Mon Oct 30 18:20:20.705047 2017] [ssl:info] [pid 372:tid 140147985901312] [client 172.17.0.1:34012] AH01996: SSL handshake failed: HTTP spoken on HTTPS port; trying to send HTML error page
[Mon Oct 30 18:20:20.705107 2017] [ssl:info] [pid 372:tid 140147985901312] SSL Library Error: error:1407609C:SSL routines:SSL23_GET_CLIENT_HELLO:http request -- speaking HTTP to HTTPS port!?

我认为这是有意义的，因为代理协议不期望直接与代理建立HTTPS连接。

我会尝试使用apache的输出过滤器功能。

AddOutputFilterByType MOD_PAGESPEED_OUTPUT_FILTER text / html
