如何在 HTTPS 服务器后面设置 Keycloak

我已按照此处的步骤操作 https://www.keycloak.org/docs/3.4/server_installation/index.html#enable-https-ssl-with-a-reverse-proxy 但当我尝试打开时，却发现缺少了一些东西https://auth.solidsense.tk/auth/realms/master/.well-known/openid-configuration 端点没有正确的方案（http 而不是 https），我无法进入管理控制台

        listen 80;
        listen [::]:80;


        server_name auth.solidsense.tk;
        root /var/www/auth.solidsense.tk/html;
        index index.html index.htm index.nginx-debian.html;


        location /{ 
              proxy_set_header Host $host; 
              proxy_set_header X-Real-IP  $remote_addr; 
              proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
              proxy_set_header X-Forwarded-Proto $scheme;
              proxy_set_header   Cookie $http_cookie;                 
              proxy_pass http://localhost:9080;

    }


    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/auth.solidsense.tk/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/auth.solidsense.tk/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}

我知道这个问题已经很久了，但仍然没有答案，而且从浏览量来看，这个问题一次又一次地出现。我猜很多人最终都会自己找到答案，但没有发帖，所以我会发帖对我有用的。

典型场景 Internet -> HTTPS -> ModSecNginx -> HTTP -> Keycloak

Keycloak 4.4.0 ModSecurity-nginx v1.0.0（内联/本地/远程加载规则：0/903/0）

在完成“所有操作”之后，我遇到了同样的问题，keycloak 代理转发为真，nginx 建议......等等。

curl https://modsec.redacted.com/auth/realms/master/.well-known/openid-configuration
{"issuer":"http://modsec.redacted.com/auth/realms/master","authorization_endpoint":"http://modsec.redacted.com/auth/realms/master/protocol/openid-connect/auth"....

配置

    server
    {
      listen 80;
      listen [::]:80;
      location /
        {

          modsecurity on;
          modsecurity_rules '
            SecRuleEngine On
            SecDebugLog /tmp/modsec_debug.log
            # Debug Levels are 3,4,5,9
            SecDebugLogLevel 3
            # The below rules are disabled, else keycloak does not work at paranoia level 5
            SecRuleRemoveById 942432 920273 942421 942420
          ';
          proxy_set_header    Host               $http_host;
          proxy_set_header    X-Real-IP          $remote_addr;
          proxy_set_header    X-Forwarded-For    $proxy_add_x_forwarded_for;
          proxy_set_header    Cookie              $http_cookie;
          proxy_set_header    X-Forwarded-Host   $host;
          proxy_set_header    X-Forwarded-Server $host;
          proxy_set_header    X-Forwarded-Port   $server_port;
          proxy_set_header    X-Forwarded-Proto  $scheme;
          proxy_pass http://keycloak:8080;
        }
    }

这就是我必须做的

改变：

          proxy_set_header    X-Forwarded-Proto  $scheme;

到：

          proxy_set_header    X-Forwarded-Proto  https;

结果

curl https://modsec.redacted.com/auth/realms/master/.well-known/openid-configuration
{"issuer":"https://modsec.redacted.com:80/auth/realms/master","authorization_endpoint":"https://modsec.redacted.com:80/auth/realms/master/protocol/openid-connect/auth"

你知道发生什么事了吗？

然后改变：

          proxy_set_header    X-Forwarded-Port   $server_port;

到：

          proxy_set_header    X-Forwarded-Proto  443;

或者，将其完全取出。

结果

curl https://modsec.redacted.com/auth/realms/master/.well-known/openid-configuration
{"issuer":"https://modsec.redacted.com/auth/realms/master","authorization_endpoint":"https://modsec.redacted.com/auth/realms/master/protocol/openid-connect/auth",

您的管理控制台也将开始工作。我确信 Nginx 有适合此的变量（$request_scheme，或者 $client_scheme 可能？）。

这就对了！
