This page describes how to install Ansible on different platforms.Ansible is an agentless automation tool that by default manages machines over the SSH protocol. Once installed, Ansible doesnot add a database, and there will be no daemons to start or keep running. You only need to install it on one machine (which could easily be a laptop) and it can manage an entire fleet of remote machines from that central point. When Ansible manages remote machines, it does not leave software installed or running on them, so there’s no real question about how to upgrade Ansible when moving to a new version.
The latest stable release of FEniCS is version 2019.1.0, which was released on April 19th 2019. FEniCS on Docker To use our prebuilt, high-performance Docker images, first install Docker CE for your platform (Windows, Mac or Linux) and then run the following command: crayon-5f7f92e3a936/ To run the FEniCS Docker image, use the command fenicsproject run. The recommended way to install the components of the mac platform is using ghcup to install ghc and cabal-install, and following the instructions at haskellstack.org to install stack. $ sudo apt-get install haskell-platform.
You install Ansible on a control node, which then uses SSH (by default) to communicate with your managed nodes (those end devices you want to automate).
Sudo apt-get install handbrake-cli handbrake-gtk Run HandBrakeCLI to use HandBrake on the command line. Run ghb to launch HandBrake’s graphical user interface. You may wish to right-click on the icon and select “Lock to Launcher” for easy access in the future. Flatpak bundles. Flatpak bundles of HandBrake for Linux are available on the.
Currently Ansible can be run from any machine with Python 2 (version 2.7) or Python 3 (versions 3.5 and higher) installed.This includes Red Hat, Debian, CentOS, macOS, any of the BSDs, and so on.Windows is not supported for the control node, read more about this in Matt Davis’s blog post.
When choosing a control node, bear in mind that any management system benefits from being run near the machines being managed. If you are running Ansible in a cloud, consider running it from a machine inside that cloud. In most cases this will work better than on the open Internet.
Note
macOS by default is configured for a small number of file handles, so if you want to use 15 or more forks you’ll need to raise the ulimit with
sudolaunchctllimitmaxfilesunlimited
. This command can also fix any “Too many open files” error.Warning
Please note that some modules and plugins have additional requirements. For modules these need to be satisfied on the ‘target’ machine (the managed node) and should be listed in the module specific docs.
On the managed nodes, you need a way to communicate, which is normally SSH. Bydefault this uses SFTP. If that’s not available, you can switch to SCP inansible.cfg. You also need Python 2 (version 2.6 or later) or Python 3 (version 3.5 orlater).
Note
- If you have SELinux enabled on remote nodes, you will also want to installlibselinux-python on them before using any copy/file/template related functions in Ansible. Youcan use the yum module or dnf module in Ansible to install this package on remote systemsthat do not have it.
- By default, before the first Python module in a playbook runs on a host, Ansible attempts to discover a suitable Python interpreter on that host. You can override the discovery behavior by setting the ansible_python_interpreter inventory variable to a specific interpreter, and in other ways. See Interpreter Discovery for details.
- Ansible’s raw module, and the script module, do not dependon a client side install of Python to run. Technically, you can use Ansible to install a compatibleversion of Python using the raw module, which then allows you to use everything else.For example, if you need to bootstrap Python 2 onto a RHEL-based system, you can install itas follows:
Which Ansible version to install is based on your particular needs. You can choose any of the following ways to install Ansible:
- Install the latest release with your OS package manager (for Red Hat Enterprise Linux (TM), CentOS, Fedora, Debian, or Ubuntu).
- Install with
pip
(the Python package manager). - Install
ansible-base
from source to access the development (devel
) version to develop or test the latest features.
Note
You should only run
ansible-base
from devel
if you are modifying ansible-base
, or trying out features under development. This is a rapidly changing source of code and can become unstable at any point.Ansible creates new releases two to three times a year. Due to this short release cycle,minor bugs will generally be fixed in the next release rather than maintaining backports on the stable branch.Major bugs will still have maintenance releases when needed, though these are infrequent.
On Fedora:
On RHEL and CentOS:
RPMs for RHEL 7 and RHEL 8 are available from the Ansible Engine repository.
To enable the Ansible Engine repository for RHEL 8, run the following command:
To enable the Ansible Engine repository for RHEL 7, run the following command:
RPMs for currently supported versions of RHEL and CentOS are also available from EPEL.
Note
Since Ansible 2.10 for RHEL is not available at this time, continue to use Ansible 2.9.
Ansible can manage older operating systems that contain Python 2.6 or higher.
Ubuntu builds are available in a PPA here.
To configure the PPA on your machine and install Ansible run these commands:
Note
On older Ubuntu distributions, “software-properties-common” is called “python-software-properties”. You may want to use
apt-get
instead of apt
in older versions. Also, be aware that only newer distributions (in other words, 18.04, 18.10, and so on) have a -u
or --update
flag, so adjust your script accordingly.Debian/Ubuntu packages can also be built from the source checkout, run:
You may also wish to run from source to get the development branch, which is covered below.
Debian users may leverage the same source as the Ubuntu PPA.
Add the following line to /etc/apt/sources.list:
Then run these commands:
Note
This method has been verified with the Trusty sources in Debian Jessie and Stretch but may not be supported in earlier versions. You may want to use
apt-get
instead of apt
in older versions.To install the newest version, you may need to unmask the Ansible package prior to emerging:
Though Ansible works with both Python 2 and 3 versions, FreeBSD has different packages for each Python version.So to install you can use:
or:
You may also wish to install from ports, run:
Sudo Apt Get Install For Macos
You can also choose a specific version, for example
ansible25
.Older versions of FreeBSD worked with something like this (substitute for your choice of package manager):

The preferred way to install Ansible on a Mac is with
pip
.The instructions can be found in Installing Ansible with pip. If you are running macOS version 10.12 or older, then you should upgrade to the latest
pip
to connect to the Python Package Index securely. It should be noted that pip must be run as a module on macOS, and the linked pip
instructions will show you how to do that.Note
If you have Ansible 2.9 or older installed, you need to use
pipuninstallansible
first to remove older versions of Ansible before re-installing it.If you are installing on macOS Mavericks (10.9), you may encounter some noise from your compiler. A workaround is to do the following:
Ansible is available for Solaris as SysV package from OpenCSW.
Ansible is available in the Community repository:
The AUR has a PKGBUILD for pulling directly from GitHub called ansible-git.
Also see the Ansible page on the ArchWiki.
Ansible build script is available in the SlackBuilds.org repository.Can be built and installed using sbopkg.
Create queue with Ansible and all dependencies:
Build and install packages from a created queuefile (answer Q for question if sbopkg should use queue or package):
Ansible and its dependencies are available as part of the sysadmin host management bundle:
Update of the software will be managed by the swupd tool:
Ansible can be installed with
pip
, the Python package manager. If pip
isn’t already available on your system of Python, run the following commands to install it:Note
If you have Ansible 2.9 or older installed, you need to use
pipuninstallansible
first to remove older versions of Ansible before re-installing it.Then install Ansible 1:
In order to use the
paramiko
connection plugin or modules that require paramiko
, install the required module 2:If you wish to install Ansible globally, run the following commands:
Note
Running
pip
with sudo
will make global changes to the system. Since pip
does not coordinate with system package managers, it could make changes to your system that leaves it in an inconsistent or non-functioning state. This is particularly true for macOS. Installing with --user
is recommended unless you understand fully the implications of modifying global files on the system.Note
Older versions of
pip
default to http://pypi.python.org/simple, which no longer works.Please make sure you have the latest version of pip
before installing Ansible.If you have an older version of pip
installed, you can upgrade by following pip’s upgrade instructions .Starting in version 2.10, Ansible is made of two packages. You need to first uninstall the old Ansible version (2.9 or earlier) before upgrading.If you do not uninstall the older version of Ansible, you will see the following message, and no change will be performed:
As explained by the message, to upgrade you must first remove the version of Ansible installed and then install itto the latest version.
In Ansible 2.10 and later, The ansible/ansible repository contains the code for basic features and functions, such as copying module code to managed nodes. This code is also known as
ansible-base
.Note
You should only run
ansible-base
from devel
if you are modifying ansible-base
or trying out features under development. This is a rapidly changing source of code and can become unstable at any point.Note
If you have Ansible 2.9 or older installed, you need to use
pipuninstallansible
first to remove older versions of Ansible before re-installing it.You can install the development version of
ansible-base
directly from GitHub with pip.Replace
devel
in the URL mentioned above, with any other branch or tag on GitHub to install older versions of Ansible (prior to ansible-base
2.10.) This installs all of Ansible.See Running ansible-base from source (devel) for instructions on how to run
ansible-base
directly from source, without the requirement of installation.Note
If you have Ansible 2.9 or older installed, you need to use
pipuninstallansible
first to remove older versions of Ansible before re-installing it.Ansible can also be installed inside a new or existing
virtualenv

In Ansible 2.10 and later, The ansible/ansible repository contains the code for basic features and functions, such as copying module code to managed nodes. This code is also known as
ansible-base
.Note
You should only run
ansible-base
from devel
if you are modifying ansible-base
or trying out features under development. This is a rapidly changing source of code and can become unstable at any point.ansible-base
is easy to run from source. You do not need root
permissionsto use it and there is no software to actually install. No daemonsor database setup are required.Note
If you want to use Ansible Tower as the control node, do not use a source installation of Ansible. Please use an OS package manager (like
apt
or yum
) or pip
to install a stable version.To install from source, clone the
ansible-base
git repository:Once
git
has cloned the ansible-base
repository, setup the Ansible environment:Using Bash:

If you want to suppress spurious warnings/errors, use:
If you don’t have
pip
installed in your version of Python, install it:Ansible also uses the following Python modules that need to be installed 1:
To update
ansible-base
checkouts, use pull-with-rebase so any local changes are replayed.Once running the env-setup script you’ll be running from checkout and the default inventory filewill be
/etc/ansible/hosts
. You can optionally specify an inventory file (see How to build your inventory)other than /etc/ansible/hosts
:You can read more about the inventory file at How to build your inventory.
Now let’s test things with a ping command:
You can also use “sudo make install”.
Packaging Ansible or wanting to build a local package yourself, but don’t want to do a git checkout? Tarballs of releases are available from
pypi
as https://pypi.python.org/packages/source/a/ansible/ansible-{{VERSION}}.tar.gz. You can make VERSION a variable in your package managing system that you update in one place whenever you package a new version. Alternately, you can download https://pypi.python.org/project/ansible to get the latest stable release.Note
If you are creating your own Ansible package, you must also download or package
ansible-base
as part of your Ansible package. You can download it as https://pypi.python.org/packages/source/a/ansible-base/ansible-base-{{VERSION}}.tar.gz.These releases are also tagged in the git repository with the release version.
As of Ansible 2.9, shell completion of the Ansible command line utilities is available and provided through an optional dependencycalled
argcomplete
. argcomplete
supports bash, and has limited support for zsh and tcsh.You can install
python-argcomplete
from EPEL on Red Hat Enterprise based distributions, and or from the standard OS repositories for many other distributions.For more information about installing and configuration see the argcomplete documentation.
On Fedora:
On RHEL and CentOS:
There are 2 ways to configure
argcomplete
to allow shell completion of the Ansible command line utilities: globally or per command.Global completion requires bash 4.2.
This will write a bash completion file to a global location. Use
--dest
to change the location.If you do not have bash 4.2, you must register each script independently.
You should place the above commands into your shells profile file such as
~/.profile
or ~/.bash_profile
.See the argcomplete documentation.
You may also wish to follow the GitHub project ifyou have a GitHub account. This is also where we keep the issue tracker for sharingbugs and feature ideas.
