Dependency Installation
-----------------------

ZeroMQ and swig need to be installed first.

For installs using `python installed via homebrew`_, sudo should be unnecessary:

.. _`python installed via homebrew`: https://github.com/mxcl/homebrew/wiki/Homebrew-and-Python

Using homebrew with
  `XCode Command Line Tool (XCode: Preferences: Downloads: Command Line Tools: Install)`_ pre-installed:

.. _`XCode Command Line Tool (XCode: Preferences: Downloads: Command Line Tools: Install)`: https://developer.apple.com/xcode/

.. code-block:: bash

    brew install python
    brew install swig
    brew install zmq
    pip install salt

This should pip install salt and its dependencies, such as:
  Jinja2 M2Crypto msgpack-python pycrypto PyYAML pyzmq markupsafe

Whereas when using macports, zmq, swig, and pip may need to be installed this way:

.. code-block:: bash

    sudo port install py-zmq
    sudo port install py27-m2crypto
    sudo port install py27-crypto
    sudo port install py27-msgpack
    sudo port install swig-python
    sudo port install py-pip

For installs using the OS X system python, pip install needs to use 'sudo':

.. code-block:: bash

    sudo pip install salt

Salt-Master Customizations
--------------------------

To run salt-master on OS X, the root user maxfiles limit must be increased:

.. code-block:: bash

    sudo launchctl limit maxfiles 4096 8192

And sudo add this configuration option to the /etc/salt/master file:

.. code-block:: bash

    max_open_files: 8192

Now the salt-master should run without errors:

.. code-block:: bash

    sudo /usr/local/share/python/salt-master --log-level=all

Post-installation tasks
