This article details how to enable Passenger on your domain within the DreamHost panel.
- Navigate to the (Panel > 'Domains' > 'Manage Domains') page.
- Click the Edit button to the right of your domain under the 'Web Hosting' column.
- The 'Manage Domains' settings page opens:
- Scroll down to the 'Web Options' section and check the 'Passenger (Ruby/NodeJS/Python apps only):' check box.
- A WARNING dialog box then appears:
- Click the OK button. The panel adds the /public subdirectory for you.
- Click the Change settings button to save your changes.
- Whenever the code or configuration files for your application are modified, you must create or update the modification date of the file "tmp/restart.txt" in the application's root directory tree in order to trigger Passenger to reinitialize the application. Passenger caches many resources so changes are not recognized unless the modification date of "tmp/restart.txt" is changed.
- The most common method to make this change is to run the following command via SSH.
[server]$ "touch tmp/restart.txt" .
The "public" subdirectory
- Passenger maps the directory named "public" to be the document root for your domain/subdomain.
- If a static HTML file named "public/index.html" exists, it's then used as the response for requests for the root document (i.e., "/").
- If you want your application to handle requests for the root document, then you must first remove "public/index.html" (if it exists).
- By default, Ruby on Rails creates a static "public/index.html" file.
Likewise, a file inside the "public" subdirectory that is named with one of the suffixes recognized by Apache (e.g., "public/foo.cgi" or "public/foo.pl") will be treated as an executable CGI script in the usual Apache fashion. (See CGI for more information.)
