Upgrading to Phusion Passenger 2.2.11
When under high load, Apache was freezing and stop responding to requests in 2.2.10 & 2.2.9 version of Passenger.
More information about the problem can be found at the following discussion thread:
http://groups.google.com/group/phusion-passenger/t/d5bb2f17c8446ea0
Its worth while to upgrade to the latest version of Phusion Passenger 2.2.11
How to upgrade to 2.2.11?
Via a gem
Install it with the following command:
gem install passenger
Next, run:
passenger-install-apache2-module
Or, if you’re an Nginx user:
passenger-install-nginx-module
On successful installation – you will see something like – for Apache:
The Apache 2 module was successfully installed.
Please edit your Apache configuration file, and add these lines:
LoadModule passenger_module /opt/ruby-enterprise-1.8.7-2010.01/lib/ruby/gems/1.8/gems/passenger-2.2.11/ext/apache2/mod_passenger.so
PassengerRoot /opt/ruby-enterprise-1.8.7-2010.01/lib/ruby/gems/1.8/gems/passenger-2.2.11
PassengerRuby /opt/ruby-enterprise-1.8.7-2010.01/bin/ruby
After you restart Apache, you are ready to deploy any number of Ruby on Rails
applications on Apache, without any further Ruby on Rails-specific
configuration!
Copy & paste the above three lines into Apache config /etc/apache2/conf.d/passenger and restart the Apache /etc/init.d/apache2 restart server..
