memcached Cookbook

Installs memcached and provides a define to set up an instance of memcache via runit.

Requirements

A runit service can be set up for instances using the memcache_instance definition.

Platforms

• Ubuntu 10.04, 12.04
• CentOS 5.8, 6.3
• openSUSE 12.3
• SLES 12 SP2
• SmartOS base64 1.8.1 - Note that SMF directly configures memcached with no opportunity to alter settings. If you need custom parameters, use the memcached_instance provider instead.

May work on other systems with or without modification.

Cookbooks

• runit

Attributes

The following are node attributes passed to the template for the runit service.

• memcached['memory'] - maximum memory for memcached instances.
• memcached['user'] - user to run memcached as.
• memcached['port'] - TCP port for memcached to listen on.
• memcached['udp_port'] - UDP port for memcached to listen on.
• memcached['listen'] - IP address for memcache to listen on, defaults to 0.0.0.0 (world accessible).
• memcached['maxconn'] - maximum number of connections to accept (defaults to 1024)
• memcached['max_object_size'] - maximum size of an object to cache (defaults to 1MB)
• memcached['logfilename'] - logfile to which memcached output will be redirected in /var/log/$logfilename.

Usage

Simply set the attributes and it will configure the /etc/memcached.conf file. If you want to use multiple memcached instances, you'll need to modify the recipe to disable the startup script and the template in the default recipe.

Use the definition, memcached_instance, to set up a runit service for the named memcached instance.

memcached_instance 'myproj'

The recipe also reads in whether to start up memcached from a /etc/default/memcached "ENABLE_MEMCACHED" setting, which is "yes" by default.
