Installation Using pip
======================
Since Salt is on `PyPI`_, it can be installed using pip, though most users
prefer to install using RPMs (which can be installed from `EPEL`_).
Installation from pip is easy:
.. _`PyPI`: https://pypi.python.org/pypi/salt
.. code-block:: bash
pip install salt
.. warning::
If installing from pip (or from source using ``setup.py install``), be
advised that the ``yum-utils`` package is needed for Salt to manage
packages. Also, if the Python dependencies are not already installed, then
you will need additional libraries/tools installed to build some of them.
More information on this can be found :ref:`here
<installing-for-development>`.
Installation from EPEL
======================
Beginning with version 0.9.4, Salt has been available in `EPEL`_. It is
installable using yum. Salt should work properly with all mainstream
derivatives of RHEL, including CentOS, Scientific Linux, Oracle Linux and
Amazon Linux. Report any bugs or issues on the `issue tracker`__.
.. __: https://github.com/saltstack/salt/issues
On RHEL6, the proper Jinja package 'python-jinja2' was moved from EPEL to the
"RHEL Server Optional Channel". Verify this repository is enabled before
installing salt on RHEL6.
.. _`EPEL`: http://fedoraproject.org/wiki/EPEL
Enabling EPEL on RHEL
---------------------
If EPEL is not enabled on your system, you can use the following commands to
enable it.
For RHEL 5:
.. code-block:: bash
rpm -Uvh http://mirror.pnl.gov/epel/5/i386/epel-release-5-4.noarch.rpm
For RHEL 6:
.. code-block:: bash
rpm -Uvh http://ftp.linux.ncsu.edu/pub/epel/6/i386/epel-release-6-8.noarch.rpm
Installing Stable Release
-------------------------
Salt is packaged separately for the minion and the master. It is necessary only
to install the appropriate package for the role the machine will play.
Typically, there will be one master and multiple minions.
On the salt-master, run this:
.. code-block:: bash
yum install salt-master
On each salt-minion, run this:
.. code-block:: bash
yum install salt-minion
Installing from ``epel-testing``
--------------------------------
When a new Salt release is packaged, it is first admitted into the
``epel-testing`` repository, before being moved to the stable repo.
To install from ``epel-testing``, use the ``enablerepo`` argument for yum:
.. code-block:: bash
yum --enablerepo=epel-testing install salt-minion
Post-installation tasks
=======================
**Master**
To have the Master start automatically at boot time:
.. code-block:: bash
chkconfig salt-master on
To start the Master:
.. code-block:: bash
service salt-master start
**Minion**
To have the Minion start automatically at boot time:
.. code-block:: bash
chkconfig salt-minion on
To start the Minion:
.. code-block:: bash
service salt-minion start
