Configuring OTRS 5 with Memcached Support

Caching in OTRS allows you to reuse objects that have been used recently. By default, OTRS has a disk cache. However, this could not be enough if you are planning to do a cluster or you just want to speed things up. Fortunately for us, someone coded the Memcached support. So I will talk about how I did this.

In my very specific case, the VPS where I have installed my OTRS is very slow on I/O operations, so putting a Memcached configuration helped a lot!

Disclaimer: I am not the author of this patch. I just did the .patch file more friendly.

Follow these steps:

1. Install the Perl-Cache-Memcached-Fast package, if you are using my RPM's I have already package as an RPM. Just type the command yum install perl-Cache-Memcached-Fast
2. Download the Memcached Patch I have done

3. Apply the patch using your otrs/ directory as a base
4. Edit the Kernel/Config.pm file and put the following line:
   $Self->{Memcached} = {'Servers' => ['127.0.0.1:11211'], 'Parameters' => {'compress_threshold' => 10_000, 'utf8'=>1}};
5. Edit the OTRS Core::Cache Settings, enable Memcached and review the parameters
6. Restart Apache
7. Restart the OTRS daemon

Enjoy!
