通过一个 nginx 服务器为两个 rails 应用程序提供服务

通过一个 nginx 服务器为两个 rails 应用程序提供服务

我尝试按照本文中的一些教程进行操作: 在一个 nginx 中配置两个不同的应用程序服务器?

但我无法实现从 qa_server 提供 qa.example.com 和从 staging_server 提供 staging2.example.com 的目标。这是我的 nginx 站点启用文件:

(staging_server) 的内容:

upstream puma_staging {
  server unix:/home/jenkins/apps/staging_app/shared/tmp/sockets/staging-app-puma.sock fail_timeout=0;
}

server {
  server_name staging2.example.com;
  listen 80;
  return 301 https://$host$request_uri;
}

server {
  server_name staging2.example.com;
  listen 443 default_server;
  root /home/jenkins/apps/staging_app/current/public;

  try_files $uri/index.html $uri @puma_staging;

  location @puma_staging {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header   X-Forwarded-Proto https;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://puma_staging;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
  keepalive_timeout 10;
  ssl on;
  ssl_certificate "some cert";
  ssl_certificate_key "some key;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers 'something here';
}

(qa_server) 的内容:

upstream puma_qa {
  server unix:/home/jenkins/apps/qa_app/shared/tmp/sockets/qa-app-puma.sock fail_timeout=0;
}

server {
  server_name qa.example.com;
  listen 80;
  return 301 https://$host$request_uri;
}

### QA START ###

server {
  server_name qa.example.com;
  listen 443;

  root /home/jenkins/apps/qa_app/current/public;

  try_files $uri/index.html $uri @puma_qa;

  location / {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header   X-Forwarded-Proto https;
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_redirect off;
    proxy_read_timeout 150s;
    proxy_pass http://puma_qa;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
  keepalive_timeout 10;
  ssl on;
  ssl_certificate "some cert";
  ssl_certificate_key "some key;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers 'something here';
}

看起来我的暂存服务器运行良好,我可以跟踪日志并看到日志文件像这样移动tail -f /home/jenkins/apps/staging_app/current/log/staging.log

我的 qa 应用程序(在临时环境中运行)没有写入正确的日志文件,当我对其进行跟踪时,什么也tail -f /home/jenkins/apps/qa_app/current/log/staging.log没有发生。也就是说,qa.example.com 应用程序可以运行,但不知道它从哪里提供服务。

尝试使用 验证 nginx 配置nginx -t,一切看起来都很好。尝试在调试模式下运行 nginx,以便找出请求究竟从哪里路由/提供服务,就像这样service nginx stop && service nginx-debug start

正在跟踪访问(/var/log/nginx/access.log)和错误日志(/var/log/nginx/error.log),但我甚至不知道调试日志应该是什么样子。

另一个信息是,我的主机名 staging2.example.com 是指向我服务器 IP 的 A 记录,而我的 qa.example.com 是指向 staging2.example.com 的 CNAME

我在这里犯了什么明显的错误吗?或者我下一步应该尝试什么?

根据评论更新(添加 nginx -T 的输出):
