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. For Windows,
just install PsUtil from the binary installation file.
You can also install the following libraries in order to use optional
features (like the Web interface, exports modules, sensors...):
.. code-block:: console
pip install bottle requests batinfo https://bitbucket.org/gleb_zhulik/py3sensors/get/tip.tar.gz zeroconf netifaces pymdstat influxdb elasticsearch potsdb statsd pystache docker-py pysnmp pika py-cpuinfo bernhard cassandra-driver scandir pyzmq
To upgrade Glances to the latest version:
.. code-block:: console
pip install --upgrade glances
pip install --upgrade bottle requests batinfo https://bitbucket.org/gleb_zhulik/py3sensors/get/tip.tar.gz zeroconf netifaces pymdstat influxdb elasticsearch potsdb statsd pystache docker-py pysnmp pika py-cpuinfo bernhard cassandra-driver scandir pyzmq
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
Additionally, If you want to use your own glances.conf file, you can create your
own Dockerfile:
.. code-block:: console
FROM nicolargo/glances
COPY glances.conf /glances/conf/glances.conf
CMD python -m glances -C /glances/conf/glances.conf $GLANCES_OPT
Alternatively, you can specify something along the same lines with docker run options:
.. code-block:: console
docker run -v ./glances.conf:/glances/conf/glances.conf -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host -it docker.io/nicolargo/glances
Where ./glances.conf is a local directory containing your glances.conf file.
Run the container in *Web server mode* (notice the GLANCES_OPT environment variable setting parameters for the glances startup command) :
.. code-block:: console
docker run -d --restart="always" -p 61208-61209:61208-61209 -e GLANCES_OPT="-w" -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host docker.io/nicolargo/glances

---------
At the moment, packages exist for the following GNU/Linux distributions:
- Arch Linux
- Debian
- Fedora/CentOS/RHEL
- Gentoo
- Slackware (SlackBuild)
- Ubuntu
- Void Linux
So you should be able to install it using your favorite package manager.
Be aware that the Glances version can not be the latest one using this method.

.. code-block:: console
# pkg install py27-glances
To install Glances from ports:
.. code-block:: console
# cd /usr/ports/sysutils/py-glances/
# make install clean
OS X
----

Homebrew
````````
.. code-block:: console
$ brew install python
$ pip install glances

$ sudo port install glances
Windows
-------
Install `Python`_ for Windows (Python 2.7.9+ and 3.4+ ship with pip) and
then just:
.. code-block:: console
$ pip install glances
You can also install the following libraries in order to use optional
features (like the Web interface, exports modules, sensors...):
.. code-block:: console
pip install bottle requests zeroconf netifaces influxdb elasticsearch potsdb statsd pystache pysnmp pika py-cpuinfo bernhard cassandra scandir
Source
------
To install Glances from source:
.. code-block:: console

$ glances -s
on the server side and run:
.. code-block:: console
$ glances -c <ip>
