Installation
============

Several method to test/install Glances on your system. Choose your weapon !

Glances Auto Install script: the total way
------------------------------------------

To install both dependencies and latest Glances production ready version
(aka *master* branch), just enter the following command line:

.. code-block:: console

    curl -L https://bit.ly/glances | /bin/bash

or

.. code-block:: console

    wget -O- https://bit.ly/glances | /bin/bash

*Note*: Only supported on some GNU/Linux distributions. If you want to
support other distributions, please contribute to `glancesautoinstall`_.

PyPI: The simple way
--------------------

Glances is on ``PyPI``. By using PyPI, you are sure to have the latest
stable version.

To install, simply use ``pip``:

.. code-block:: console

    pip install glances

*Note*: Python headers are required to install `psutil`_. For example,
on Debian/Ubuntu you need to install first the *python-dev* package.
For Fedora/CentOS/RHEL install first *python-devel* package.

You can also install the following libraries in order to use optional
features (like the Web interface):

.. code-block:: console

    pip install bottle batinfo https://bitbucket.org/gleb_zhulik/py3sensors/get/tip.tar.gz zeroconf netifaces pymdstat influxdb potsdb statsd pystache docker-py pysnmp pika py-cpuinfo scandir

Install or upgrade Glances from the Git ``develop`` repository:

.. code-block:: console

    git clone -b develop https://github.com/nicolargo/glances.git


To upgrade Glances to the latest version:

.. code-block:: console

    pip install --upgrade glances

If you need to install Glances in a specific user location, use:

.. code-block:: console

    export PYTHONUSERBASE=~/mylocalpath
    pip install --user glances

Docker: the funny way
---------------------

A Glances container is available. It will include the latest development HEAD version. You can use it to monitor your server and all your others containers !

Get the Glances container:

.. code-block:: console

    docker pull nicolargo/glances

Run the container in console mode:

.. code-block:: console

    docker run -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host -it docker.io/nicolargo/glances
