Wordpress 为什么我的AWS Lightsail实例；运行状况检查：失败"；何时连接到负载平衡器？

我在

AWS Lightsail

中创建了一个

AWS Lightsail实例和一个
负载平衡器。
当我将实例连接到负载平衡器时，我得到以下状态：
运行状况检查：失败
。我不知道为什么？我去我的WordPress，一切正常

更新：
正如我所知，LB只在端口80上检查我的实例运行状况，这是HTTP协议。我检查了它，它总是返回HTTP/1.1 301永久移动的
。我已经在httpd prefix.conf中添加了这些：

SetEnvIf x-forwarded-proto https HTTPS=on

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} =http
RewriteRule . https://%{HTTP:Host}%{REQUEST_URI} [L,R=permanent]

if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false)
    $_SERVER['HTTPS']='on';

RewriteEngine On
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP_HOST} !^localhost
  RewriteCond %{HTTP_HOST} !^[0-9]+.[0-9]+.[0-9]+.[0-9]+(:[0-9]+)?$
  RewriteCond %{REQUEST_URI} !^/\.well-known
  RewriteRule ^/(.*) https://%{SERVER_NAME}/$1 [R,L]

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{REQUEST_URI} !health.txt
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

在wp config.php中：

SetEnvIf x-forwarded-proto https HTTPS=on

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} =http
RewriteRule . https://%{HTTP:Host}%{REQUEST_URI} [L,R=permanent]

if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false)
    $_SERVER['HTTPS']='on';

RewriteEngine On
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP_HOST} !^localhost
  RewriteCond %{HTTP_HOST} !^[0-9]+.[0-9]+.[0-9]+.[0-9]+(:[0-9]+)?$
  RewriteCond %{REQUEST_URI} !^/\.well-known
  RewriteRule ^/(.*) https://%{SERVER_NAME}/$1 [R,L]

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{REQUEST_URI} !health.txt
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

而这些在bitnami.conf中：

SetEnvIf x-forwarded-proto https HTTPS=on

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} =http
RewriteRule . https://%{HTTP:Host}%{REQUEST_URI} [L,R=permanent]

if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false)
    $_SERVER['HTTPS']='on';

RewriteEngine On
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP_HOST} !^localhost
  RewriteCond %{HTTP_HOST} !^[0-9]+.[0-9]+.[0-9]+.[0-9]+(:[0-9]+)?$
  RewriteCond %{REQUEST_URI} !^/\.well-known
  RewriteRule ^/(.*) https://%{SERVER_NAME}/$1 [R,L]

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{REQUEST_URI} !health.txt
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

然后重新启动我的apache，但它仍然无法工作。
因此我找到了一个关于主题的解决方案：

接下来，我需要创建一个文件
health.txt
自定义此文件的健康检查路径：
http://{my_IP_INSTANCE}/health.txt

并将这些添加到我的bitnami.conf：

SetEnvIf x-forwarded-proto https HTTPS=on

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} =http
RewriteRule . https://%{HTTP:Host}%{REQUEST_URI} [L,R=permanent]

if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false)
    $_SERVER['HTTPS']='on';

RewriteEngine On
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP_HOST} !^localhost
  RewriteCond %{HTTP_HOST} !^[0-9]+.[0-9]+.[0-9]+.[0-9]+(:[0-9]+)?$
  RewriteCond %{REQUEST_URI} !^/\.well-known
  RewriteRule ^/(.*) https://%{SERVER_NAME}/$1 [R,L]

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{REQUEST_URI} !health.txt
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

然后重新启动我的apache服务器。
您是如何定义健康检查的？请检查HCs中的预期状态代码。默认值为200，但wordpress可能会返回302或303进行自动重定向。@petern在文档中，他们说，
Lightsail在web应用程序的根目录（“/”）上对实例执行运行状况检查。我的网站正在运行@Marcin我如何检查您的HCs中的预期状态代码。先生
