How To Install MySQL 5.6 On Ubuntu 12.10 (Including memcached Plugin) - Page 2
On this page
4 Enabling The memcached Plugin
MySQL 5.6 now provides a NoSQL interface via memcached (see What's New in MySQL 5.6; this page explains how you can make use of it: http://schlueters.de/blog/archives/152-Not-only-SQL-memcache-and-MySQL-5.6.html). To use this feature, we must enable the memcached plugin - this will then automatically start a memcached daemon on port 11211, which means you don't have to install memcached separately because it's all included in the MySQL package.
First log into MySQL...
mysql -u root -p
... to find out about your MySQL version and all installed plugins:
mysql> select version();
mysql> select version();

mysql> show plugins;
If daemon_memcached is not listed, this means we must activate the memcached plugin:
mysql> show plugins;

If there's no test database, create it as follows:
mysql> CREATE DATABASE test;
Leave the MySQL shell:
mysql> quit;
Make sure you are still in the /usr/local/mysql directory and run:
mysql -u root -p < share/innodb_memcached_config.sql
Then log into MySQL again...
mysql -u root -p
... and enable the memcached plugin as follows:
mysql> INSTALL PLUGIN daemon_memcached SONAME 'libmemcached.so';
Verify that is has been activated:
mysql> show plugins;
You should now see daemon_memcached listed:
mysql> show plugins;
