pfSense + HAProxy –在一个内部IP上具有多个服务的反向代理

时间：2018-09-30 08:53:08

标签： linux reverse-proxy haproxy pfsense seafile-server

当前，我在服务器上使用HAProxy软件包使用pfSense，因为可以通过GUI轻松配置它。

我将HAProxy配置为充当与本指南相对应的反向代理：https://blog.devita.co/pfsense-to-proxy-traffic-for-websites-using-pfsense/

SSL卸载的过程非常吸引人。我的问题是，当我在同一内部IP上有多个服务（开放端口）时，似乎无法正常工作。

示例：

  • 我为Service1配置了service1.domain.com，端口为8000（10.100.10.101:8000），它可以正常工作。
  • 现在我需要同一台计算机上的另一个端口（例如10.100.10.101:8082）以及其他服务。如果我配置了另一个指向相同IP但具有不同端口的后端，即使我访问service1.domain.com，我也只能访问第二个服务（service2.domain.com）。

我的用例是我正在尝试设置Seafile，该文件使用Web GUI的端口8000和文件服务器的端口8082。现在，我可以访问Web GUI，但不能上传，下载或共享文件。

我的配置：

我能够在Reddit上一位出色的用户的帮助下解决问题。

第一个问题是我没有正确配置前端，因此有3个default_backends。这就是每个服务都指向同一虚拟机的原因。为了解决这个问题，我只需要添加与我的ACL名称相对应的if条件。

第二个问题是我的Service2在HAProxy统计信息页面上显示为DOWN。我不得不将运行状况检查方法从HTTP更改为Basic，最终解决了所有问题。

这是有效的配置：

TLDR：我没有正确配置操作表，并进行了错误的健康检查。
