嵌入 Tomcat 的 Apache SSL 反向代理

Question

我正在尝试为通过 SSL 运行 tomcat 嵌入服务器的应用程序设置反向代理。该应用程序需要在端口 9002 上通过 SSL 运行，因此我无法为此应用程序“禁用 SSL”。当前的设置架构如下所示：

[192.168.0.10:443 - Apache with mod_proxy] --> [192.168.0.10:9002 - Tomcat App]

在谷歌搜索如何进行这样的设置（和测试）之后，我遇到了这个：

https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/861137

这导致我当前的配置（尝试模拟 wget 的 --secure-protocol=sslv3 选项）

/etc/apache2/sites/enabled/default-ssl:

<VirtualHost _default_:443>

    SSLEngine On
    SSLCertificateFile    /etc/ssl/certs/ssl-cert-snakeoil.pem
    SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key

    SSLProxyEngine On
    SSLProxyProtocol SSLv3
    SSLProxyCipherSuite SSLv3
    ProxyPass /test/ https://192.168.0.10:9002/
    ProxyPassReverse /test/ https://192.168.0.10:9002/

    LogLevel debug
    ErrorLog /var/log/apache2/error-ssl.log
    CustomLog /var/log/apache2/access-ssl.log combined
</VirtualHost>

问题是错误日志显示错误：14077102：SSL 例程：SSL23_GET_SERVER_HELLO：不支持的协议

如果我做一个

wget --secure-protocol=sslv3 --no-check-certificate https://192.168.0.10:9002/ 

它运行良好，但来自 apache 不起作用。

我在运行 apache2 并启用 mod_proxy 和 mod_ssl 的最新更新的 Ubuntu 服务器上：

~$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=12.04
DISTRIB_CODENAME=precise
DISTRIB_DESCRIPTION="Ubuntu 12.04.2 LTS"

~# dpkg -s apache2
...
Version: 2.2.22-1ubuntu1.2
...

~# dpkg -s openssl
...
Version: 1.0.1-4ubuntu5.7
...

希望任何人都可以提供帮助

听起来您可能想尝试编辑 Tomcat 应用程序的 server.xml，并在定义连接器端口的位置添加如下内容：

proxyName="mysite.example.com" proxyPort="443" scheme="https" secure="true"
