linux - 如何使用 GCP 负载均衡器将 HTTP 重定向到 HTTPS

Question

我正在 GCP 中使用 2 个节点 (Apache httpd) 设置负载均衡器，域为 lblb.tonegroup.net。

目前我的负载均衡器工作正常，流量正在两个节点之间切换，但我如何配置重定向 http://lblb.tonegroup.net至 https://lblb.tonegroup.net ？

是否可以在负载均衡器级别配置它，或者我需要在 apache 级别配置它？我已安装 Google 托管 SSL 证书(仅供引用)。

Answer 1

现在，可以通过负载均衡器的流量管理从 http 重定向到 https。

下面是如何在其文档中进行设置的示例: https://cloud.google.com/load-balancing/docs/https/setting-up-traffic-management#console

基本上，您将创建两个“转发规则”:targetproxy 和 urlmap。

2 个 URLMap

• 在第一个 URL 映射中，您只需设置重定向。定义重定向规则如下，这里不需要定义后端服务
  • httpsRedirect: true
  • redirectResponseCode:找到
• 在第二张 map 中，您必须在那里定义后端服务

2条转发规则

• 第一个转发规则是服务 http 请求，所以基本上是端口 80
• 第二条转发规则是为 http 请求提供服务，因此端口 443

2 个目标代理

• 第一个目标代理是 targetHttpProxy，这将是第一个转发规则转发到的位置并映射到第一个 URLMap
• 第二个目标代理是 targetHttpsProxy，其中第二个转发规则转发到并映射到第二个 URLMap
