Installing Percona Toolkit
==========================

Percona provides packages for most popular 64-bit Linux distributions:

* Debian 7 ("wheezy")
* Debian 8 ("jessie")
* Ubuntu 14.04 LTS (Trusty Tahr)
* Ubuntu 16.04 LTS (Xenial Xerus)
* Ubuntu 16.10 (Yakkety Yak)
* Ubuntu 17.04 (Zesty Zapus)
* Red Hat Enterprise Linux or CentOS 6 (Santiago)
* Red Hat Enterprise Linux or CentOS 7 (Maipo)

.. note:: Percona Toolkit should work on other DEB-based and RPM-based systems
   (for example, Oracle Linux and Amazon Linux AMI),
   but it is tested only on those listed above.

It is recommended to install Percona software from official repositories:

1. Configure Percona repositories as described in
   `Percona Software Repositories Documentation
   <https://www.percona.com/doc/percona-repo-config/index.html>`_.

#. Install Percona Toolkit using the corresponding package manager:

   * For Debian or Ubuntu::

      sudo apt-get install percona-toolkit

   * For RHEL or CentOS::

      sudo yum install percona-toolkit

.. rubric:: Generating an instance UUID for statistics
	    
During the installating process, the percona-toolkit installer records a unique
identifier specific to the given percona-toolkit instance. This ID is a the
product UUID stored in |product-uud|. The installer copies the product_uuid to
|toolkit-uuid|.

This unique identifier is used when collecting statistics about the usage of
percona-toolkit. Note that no other information is gathered for this purpose.

In cases when the installer is not able to read the contents of
|product-uuid|, a random UUID is generated. A random UUID is
also generated if percona-toolkit is run from the binary in the *tar.gz* file.
