Nginx 配置 SSL 负载均衡器

Question

我有一个 Docker 服务器，我从 sameersbn/docker-gitlab

安装了 GitLab

我有一个监听 443:433 和 80:80 的 nginx 容器，我将使用这个来负载平衡 HTTP 和 HTTPs（带有签名证书）请求

nginx.conf

worker_processes auto;

events { worker_connections 1024; }

http {

    ##
    # Logging Settings
    ##

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;


    upstream gitlab {
        server gitlab:10080;
    }

    server {
        listen 80;
        listen 443 ssl;
        server_name www.domain.tld;

        ssl on;
        ssl_certificate         /usr/local/share/ca-certificates/domain.crt;
        ssl_certificate_key     /usr/local/share/ca-certificates/domain.key;
        ssl_trusted_certificate /usr/local/share/ca-certificates/GandiStandardSSLCA2.pem;

        ssl_session_timeout 5m;

        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers "HIGH:!aNULL:!MD5 or HIGH:!aNULL:!MD5:!3DES";
        ssl_prefer_server_ciphers on;

        root /usr/share/nginx/html;

        location /git/ {
            proxy_pass http://gitlab;
            proxy_set_header X-Forwarded-Ssl on;
            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;
        }
    }

没有 SSL，工作 url 访问 gitlab 是 http://www.domain.tld:10080/git

使用 SSL，我希望 url 为 https://www.domain.tld/git

使用此 nginx 负载均衡器配置

当我继续http://www.domain.tld/git

400 Bad Request

The plain HTTP request was sent to HTTPS port

当我继续https://www.domain.tld/git

ERR_CONNECTION_REFUSED

这是我的第一个签名证书，它应该如何工作？

Answer 1

解决这个问题需要两个步骤：

使 Nginx 将 HTTP 重定向到 HTTPS
让Gitlab监听端口 80 通过 HTTP

为什么要让Gitlab监听80端口？这种称为 SSL 卸载的技术可防止在上游和 Web 服务器之间发生冗余 HTTPS encryption/decryption。它很少需要，只有在具有复杂安全要求的不同主机的情况下才有意义。

Nginx

server {
   listen         80;
   server_name    www.domain.tld;
   return         301 https://$server_name$request_uri;
}

server {
   listen         443 ssl;
   server_name    www.domain.tld;

}

Gitlab

vi ./gitlab/config.yml
gitlab_url: "http://server1.example.com" # http rather than https
