Apache 反向代理不工作并生成 404 错误

  • 772

我安装了在 Jetty 9 上运行的 Shiboleth。通过 Apache，我有一个反向代理到 Jetty 的 8080 端口，该端口为 Shiboleth 实例提供服务。

当我在控制台中 curl http://localhost:8080/idp/shibboleth 时，正确生成了实例响应。

但是，当我在浏览器https://idp.example.com/idp/shibboleth上执行相同操作时，我收到 404 错误。

这表明反向代理无法正常工作？

这是我的 apache conf

我已经简化了我的 conf 文件以删除 https。下面的配置工作正常，但仅适用于 http。我将调查为什么 https 配置会产生 404 错误。

  1. 尝试从ServerName指令中删除端口。IE，

    ServerName idp.spectrum.com.cy

    根据https://httpd.apache.org/docs/2.4/mod/core.html#servername，端口是可选的并且是允许的，但是文档中的以下提及听起来可能是该VirtualHost配置未生效的原因（浏览器不会在Host:标头中发送端口号）。

    如果您使用基于名称的虚拟主机，则ServerName内部 <VirtualHost>部分指定必须出现在请求Host:标头中的主机名以匹配此虚拟主机。

    它应该是

    ProxyPass /idp/ http://localhost:8080/idp/

    ProxyPass请注意命令的第一个参数中的尾部斜杠。始终对齐两个参数中的尾部斜杠。

    我的VirtualHost声明非常基本，只包含最低限度的工作：

    <VirtualHost *:80>
    DocumentRoot /var/www/html

    ServerName idp.example.com
    ServerAlias idp
    ErrorLog  logs/error_log
    CustomLog logs/access_log    
</VirtualHost>
<VirtualHost *:443>
    DocumentRoot /var/www/html

    SSLEngine on
    SSLProxyEngine on
    SSLCertificateKeyFile /etc/pki/tls/private/idp.example.com.key
    SSLCertificateFile /etc/pki/tls/certs/idp.example.com.crt
    SSLCertificateChainFile /etc/pki/tls/certs/chain.crt

    ServerName idp.example.com
    ServerAlias idp
    ErrorLog  logs/ssl-error_log
    CustomLog logs/ssl-access_log combined
</VirtualHost>

    这是我的 IDP /etc/httpd/conf.d/idp.conf：

    ProxyPass /idp/ http://localhost:8080/idp/ retry=5
ProxyPassReverse /idp/ http://localhost:8080/idp/

<Proxy http://localhost:8080>
       Require all granted
       RequestHeader set X-Forwarded-Proto https
       RequestHeader set X-Proxied-Https on
       RequestHeader set Proxy-ssl-id %{SSL_SESSION_ID}s
</Proxy>
