ApacheMongrel

Configuration of Apache with Mongrel

Configure the MarkUs application in <MarkUs-APP-Root>/config/environments/production.rb (see our MarkUs [configuration documentation](wiki:InstallProd#Configure) below). Note: Please change the "secret" in the cookies related configuration section in config/environment.rb of your MarkUs instance (see <http://api.rubyonrails.org/classes/ActionController/Session/CookieStore.html>)

Configure the mongrel cluster (see config/mongrel_cluster.yml) and start the mongrel servers:

mongrel_rails cluster::start   # uses config settings defined in config/mongrel_cluster.yml

The mongrel_cluster gem isn't really necessary. It is a nice utility for starting/stopping mongrels for your MarkUs app, though. For more information concerning mongrel clusters see: [http://mongrel.rubyforge.org/wiki/MongrelCluster](http://mongrel.rubyforge.org/wiki/MongrelCluster).

Configure an httpd VirtualHost similar to the following (Reverse-Proxy-Setup):

RewriteEngine On

# define proxy balancer
<Proxy balancer://mongrel_cluster>
    BalancerMember http://127.0.0.1:8000 retry=10
    BalancerMember http://127.0.0.1:8001 retry=10
    BalancerMember http://127.0.0.1:8002 retry=10
</Proxy>
