Question

I used this railscast as a basis

# nginx_unicorn.erb
upstream unicorn-<%= application %> {
  server unix:/tmp/unicorn.<%= application %>.sock fail_timeout=0;
}

server {
  listen <%= subdomain ? subdomain : application %>.example.com:443 ssl;
  server_name <%= subdomain ? subdomain : application %>.example.com;
  root <%= current_path %>/public;
  ssl                  on;
  ssl_certificate      /opt/nginx/ssl/example.com.pem;
  ssl_certificate_key  /opt/nginx/ssl/example.com.key;
  ssl_protocols SSLv3 TLSv1;
  ssl_ciphers ALL:-ADH:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP;
  ssl_session_cache shared:SSL:10m;
  try_files $uri/index.html $uri @unicorn;

  location ^~ /assets/ {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }
  location @unicorn {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-Forwarded-Proto https;
    proxy_redirect off;
    proxy_pass http://unicorn-<%= application %>;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 4G;
  keepalive_timeout 10;
}

我在deploy.rb

中将变量设置为子域

# deploy.rb
...
role :web, "avps.example.com", "bvps.example.com", "cvps.example.com"
role :app, "avps.example.com", "bvps.example.com", "cvps.example.com"
role :db, "avps.example.com", "bvps.example.com", "cvps.example.com", :primary => true
set :subdomain, "atsp"
...

当我只部署到一台服务器时，这很有效，但我希望能够将它从它部署的当前服务器上取下来，所以如果它是avps.example.com，它会：

set :subdomain, "atsp"

或者如果是bvps.example.com，它会：

set :subdomain, "btsp"

有没有一种简单的方法可以实现这一目标？

Answer 1

我认为您正在寻找的是Capistrano多阶段部署。您可以找到维基页面here。你所要做的就是移动

set :subdomain, "atsp"

使用服务器信息进入文件（即config / deploy / atsp.rb），然后使用

部署到该服务器

cap atsp deploy

希望这有帮助。

capistrano部署到具有不同子域变量的多个服务器
