Percona Toolkits

Percona Toolkits is a suite of tools for MySQL and MariaDB. They are very useful in many situations and well documented (the main website is http://www.percona.com/software/percona-toolkit). To install them, you can add the repository:

> aptitude install python-software-properties
> apt-key adv --keyserver keys.gnupg.net --recv-keys 1C4CBDCDCD2EFD2A
> add-apt-repository 'deb http://repo.percona.com/apt wheezy main'

Then, configure APT-Pining to avoid the Percona repository overriding MariaDB's repository and conflict some packages. So, create this file at /etc/apt/preferences.d/00percona.pref and add the following content to it:

Package: *
Pin: release o=Percona Development Team
Pin-Priority: 100

You're now ready for the installation of the package:

> aptitude update
> aptitude install percona-toolkit

That's it! Several binaries starting with pt- are now available on your system.
