我在 Linode 上運行 Ubuntu 22.04 服務器并嘗試使用 Apache 和 Puma 部署一個簡單的 Sinatra 應用程式，但目前，我只能顯示索引頁面，所以我相信我錯過了一個簡單的步驟。我不確定如何將 Puma 連接到 Apache，所以可能有一些與我遺漏的相關內容。以下是關鍵檔案：
/var/www/example.com/web.rb
require 'sinatra'
get '/' do
"Hello World"
end
/var/www/example.com/config/puma.rb
workers 2
threads 5, 5
preload_app!
port 5000
environment 'development'
/etc/apache2/sites-available/example.conf
<VirtualHost *:80>
ServerAdmin info@example.com
ServerName sinatra.example.com
DocumentRoot /var/www/example.com
<Directory /var/www/example.com>
DirectoryIndex web.rb
Allow from all
</Directory>
ErrorLog /var/www/example.com/logs/errors.log
CustomLog /var/www/example.com/logs/access.log combined
RewriteEngine on
RewriteCond %{SERVER_NAME} =sinatra.example.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>
然后我運行這些命令沒有問題：
bundle install
a2ensite
systemctl reload apache2
uj5u.com熱心網友回復：
您需要設定一個反向代理（如@konstantin-strukov 所述）。這是我設定的檔案的完整串列和我運行的命令（不包括安裝 apache 和 ruby??），這樣就不會有歧義了。
/var/www/example/web.rb
require 'sinatra'
get '/' do
"Hello World"
end
/var/www/example/Procfile
web: bundle exec puma -C config/puma.rb
/var/www/example/GEMFILE
source 'http://rubygems.org'
ruby '3.0.4'
gem 'sinatra', '~>2'
gem 'puma', '~>5'
注意：最近 Sinatra 發布了 3.0.0 版本，Puma 發布了 6.0.0，這導致與 Rack 沖突，所以我需要使用以前的版本才能使其作業。
