keycloak和本地微服务前的Nginx

use*_*473 5 nginx keycloak netflix-zuul nginx-reverse-proxy

我正在尝试设置 nginx + keycloak 来保护我的 Spring Boot 微服务。

我希望配置以下结构

   internet ---https---> nginx --http--> keycloak and other protected microservices

                   keycloak <----http----> zuul and other microservices

我不知道如何设置 nginx 以正确地将原始 https 请求传递给 http 后端服务器

这是我的配置:NGINX

server {

    listen        443 ssl default_server;
    server_name   localhost; 

    ssl_certificate           /etc/nginx/localhost.crt;
    ssl_certificate_key       /etc/nginx/localhost.key;

    ssl_session_cache  builtin:1000  shared:SSL:10m;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    ssl_prefer_server_ciphers on;

    access_log            /var/log/nginx/ledgerrun.access.log;

    proxy_set_header        Host $host:443;
    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;

    # keycloak redirect 
    location /auth {
        proxy_pass       https://keycloak:8443;
    }

    location / {
        proxy_pass        http://192.168.1.15:15700;
    }

    # all /lr-servies redirect to 15700
    #location ~* ^/lr-(.*) {
    #    proxy_pass        https://192.168.1.15:15700;
    #}
}

Keycloak 实例为 https 打开 8443,为 http 打开 8080。

Spring Cloud Zuul 配置如下

server:
  port: "15700"

keycloak:
   auth-server-url: "https://my.external.ip:8443/auth"
   realm: "LedgerRunCTP"
   public-client: true
   resource: gateway-service
   security-constraints[0]:
     authRoles[0]: "user"
     securityCollections[0]:
       name: "internal services"

  1. 我必须将“auth-server-url”配置为 https,因为客户端需要先使用 keycloak 登录,并且需要 https 进行非本地连接。有没有办法只将http用于keycloak?
  2. 使用上述配置,一旦 keycloak 对用户进行身份验证,就会收到以下错误:

    纯 HTTP 请求已发送到 HTTPS 端口

设置它以实现的正确配置是什么

  1. 只有 https 到 nginx
  2. nginx 背后的所有 http
