Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

So there's this installation on a virtual server, administered by Plesk, running CentOS. The OS has been automatically updated recently - this broke a custom ruby installation. I haven't set up the original thing and am not familiar with ruby, therefore I am somewhat at a loss as to what exactly broke.

Via the package manager I made sure that ruby, and gems that were specified, are installed. I copied the original ruby folder back into the /var/www/vhost/ folder where it used to be. In there, the httpdocs folder has a soft link to the rails/servername/public folder.

So technically the website content should be as before. But the ruby/mongrel logs don't even update.

When I visit the site, Apache throws a 503 - Service Temporarily Unavailable error. The error_log is the only thing that's updating, and this is what it contains after a restart:

When I try to start mongrel_rails, I see this:

This question came from our site for computer enthusiasts and power users.

    
To you have gems installed? Can you do a 'bundle install' in your rails dir? –  m1ke Apr 23 '13 at 11:56
