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:

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

or

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:

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...):

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 scandir

To upgrade Glances to the latest version:

pip install --upgrade glances

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

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:

docker pull nicolargo/glances

Run the container in console mode:

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

Run the container in Web server mode (notice the GLANCES_OPT environment variable setting parameters for the glances startup command) :

docker run -d -p 61208:61208 -e GLANCES_OPT="-w" -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host docker.io/nicolargo/glances

Additionally, If you want to use your own glances.conf file, you can create your own Dockerfile:

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:

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.

GNU/Linux

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.

FreeBSD

To install the binary package:

# pkg install py27-glances

To install Glances from ports:

# cd /usr/ports/sysutils/py-glances/
# make install clean

OS X

OS X users can install Glances using Homebrew or MacPorts.

Homebrew

$ brew install python
$ pip install glances

MacPorts

$ sudo port install glances

Windows

Install Python for Windows (Python 2.7.9+ and 3.4+ ship with pip) and then just:

$ pip install glances

You can also install the following libraries in order to use optional features (like the Web interface, exports modules, sensors...):

pip install bottle requests zeroconf netifaces influxdb elasticsearch potsdb statsd pystache pysnmp pika py-cpuinfo bernhard cassandra scandir

Source

To install Glances from source:

$ wget https://github.com/nicolargo/glances/archive/vX.Y.tar.gz -O - | tar xz
$ cd glances-*
# python setup.py install

Note: Python headers are required to install psutil. For example, on Debian/Ubuntu you need to install first the python-dev package.
