NGINX / JENKINS：您的反向代理设置似乎已损坏

Question

我已经尝试了至少六个例子，说明如何使NGINX与Jenkins一起工作。我最近的NGINX配置基于以下示例：

https://wiki.jenkins.io/display/JENKINS/Running+Jenkins+behind+Nginx

詹金斯一直在说It appears that your reverse proxy set up is broken.我希望自己能做的事，希望我能有人发现问题出在哪里，因为我花了数小时试图解决这个问题，但无济于事。

谢谢！

Answer 1

这不是NGINX问题。

在Jenkins内部，您需要配置Jenkins URL。如果未正确设置，则会收到您观察到的错误。
检查Jenkins->管理Jenkins->配置系统=> Jenkins URL。

Answer 2

对我来说，URL 配置正确。我必须更改 Nginx 配置以包含一些额外的标头：

server {
    listen 443 ssl;
    
    server_name  my-subdomain.main-domain.com; # this is the url domain of the proxy (Load balancer in front of Jenkins)
    
    ssl_certificate /etc/nginx/certs/ssl_certificate.crt;
    ssl_certificate_key /etc/nginx/certs/ssl_key.pem;
    
    location / {

        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-Host my-subdomain.main-domain.com; # this is the url domain of the proxy (Load balancer in front of Jenkins)

        proxy_pass http://${JENKINS_PRIVATE_IP}:${JENKINS_PORT};
    }
}
