Welcome to the Ansible Installation Guide!
Ansible by default manages machines over the SSH protocol.
Once Ansible is installed, it will not 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.
Because it runs so easily from source and does not require any installation of software on remote machines, many users will actually track the development version.
Ansible’s release cycles are usually about four months long. Due to this short release cycle, minor bugs will generally be fixed in the next release versus maintaining backports on the stable branch. Major bugs will still have maintenance releases when needed, though these are infrequent.
If you are wishing to run the latest released version of Ansible and you are running Red Hat Enterprise Linux (TM), CentOS, Fedora, Debian, or Ubuntu, we recommend using the OS package manager.
For other installation options, we recommend installing via
pip, which is the Python package manager.
If you wish to track the development release to use and test the latest features, we will share information about running from source. It’s not necessary to install the program to run from source.
Currently Ansible can be run from any machine with Python 2 (version 2.7) or Python 3 (versions 3.5 and higher) installed. Windows isn’t supported for the control node.
This includes Red Hat, Debian, CentOS, macOS, any of the BSDs, and so on.
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
sudo launchctl limit maxfiles unlimited. This command can also fix any “Too many open files” error.
Please note that some modules and plugins have additional requirements. For modules these need to be satisfied on the ‘target’ machine and should be listed in the module specific docs.
On the managed nodes, you need a way to communicate, which is normally ssh. By
default this uses sftp. If that’s not available, you can switch to scp in
ansible.cfg. You also need Python 2 (version 2.6 or later) or Python 3 (version 3.5 or
If you have SELinux enabled on remote nodes, you will also want to install libselinux-python on them before using any copy/file/template related functions in Ansible. You can use the yum module or dnf module in Ansible to install this package on remote systems that do not have it.
By default, Ansible uses the python interpreter located at
/usr/bin/pythonto run its modules. However, some Linux distributions may only have a Python 3 interpreter installed to
/usr/bin/python3by default. On those systems, you may see an error like:
"module_stdout": "/bin/sh: /usr/bin/python: No such file or directory\r\n"
you can either set the ansible_python_interpreter inventory variable (see Working with Inventory) to point at your interpreter or you can install a Python 2 interpreter for modules to use. You will still need to set ansible_python_interpreter if the Python 2 interpreter is not installed to /usr/bin/python.
Ansible’s “raw” module (for executing commands in a quick and dirty way) and the script module don’t even need Python installed. So technically, you can use Ansible to install a compatible version 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 it via
$ ansible myhost --become -m raw -a "yum install -y python2"
$ sudo dnf install ansible
On RHEL and CentOS:
$ sudo yum install ansible
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:
$ sudo subscription-manager repos --enable ansible-2.8-for-rhel-8-x86_64-rpms
To enable the Ansible Engine repository for RHEL 7, run the following command:
$ sudo subscription-manager repos --enable rhel-7-server-ansible-2.8-rpms
Ansible version 2.4 and later can manage earlier operating systems that contain Python 2.6 or higher.
You can also build an RPM yourself. From the root of a checkout or tarball, use the
make rpm command to build an RPM you can distribute and install.
$ git clone https://github.com/ansible/ansible.git $ cd ./ansible $ make rpm $ sudo rpm -Uvh ./rpm-build/ansible-*.noarch.rpm
Ubuntu builds are available in a PPA here.
To configure the PPA on your machine and install ansible run these commands:
$ sudo apt update $ sudo apt install software-properties-common $ sudo apt-add-repository --yes --update ppa:ansible/ansible $ sudo apt install ansible
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 (i.e. 18.04, 18.10, etc.) have a
--update flag, so adjust your script accordingly.
Debian/Ubuntu packages can also be built from the source checkout, run:
$ make deb
You may also wish to run from source to get the latest, which is covered below.
Debian users may leverage the same source as the Ubuntu PPA.
Add the following line to /etc/apt/sources.list:
deb http://ppa.launchpad.net/ansible/ansible/ubuntu trusty main
Then run these commands:
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 93C4A3FD7BB9C367 $ sudo apt update $ sudo apt install ansible
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.
$ emerge -av app-admin/ansible
To install the newest version, you may need to unmask the ansible package prior to emerging:
$ echo 'app-admin/ansible' >> /etc/portage/package.accept_keywords
Though Ansible works with both Python 2 and 3 versions, FreeBSD has different packages for each Python version. So to install you can use:
$ sudo pkg install py27-ansible
$ sudo pkg install py36-ansible
You may also wish to install from ports, run:
$ sudo make -C /usr/ports/sysutils/ansible install
You can also choose a specific version, i.e
Older versions of FreeBSD worked with something like this (substitute for your choice of package manager):
$ sudo pkg install ansible
The preferred way to install Ansible on a Mac is via
The instructions can be found in Latest Releases via Pip section. 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.
Ansible is available for Solaris as SysV package from OpenCSW.
# pkgadd -d http://get.opencsw.org/now # /opt/csw/bin/pkgutil -i ansible
Ansible is available in the Community repository:
$ pacman -S ansible
The AUR has a PKGBUILD for pulling directly from GitHub called ansible-git.
Also see the Ansible page on the ArchWiki.
Create queue with Ansible and all dependencies:
# sqg -p ansible
Build and install packages from created queuefile (answer Q for question if sbopkg should use queue or package):
# sbopkg -k -i ansible
Ansible and its dependencies are available as part of the sysadmin host management bundle:
$ sudo swupd bundle-add sysadmin-hostmgmt
Update of the software will be managed by the swupd tool:
$ sudo swupd update
Ansible can be installed via
pip, the Python package manager. If
pip isn’t already available on your system of Python, run the following commands to install it:
$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py $ python get-pip.py --user
Then install Ansible :
$ pip install --user ansible
Or if you are looking for the latest development version:
$ pip install --user git+https://github.com/ansible/[email protected]
If you are installing on macOS Mavericks (10.9), you may encounter some noise from your compiler. A workaround is to do the following:
$ CFLAGS=-Qunused-arguments CPPFLAGS=-Qunused-arguments pip install --user ansible
In order to use the
paramiko connection plugin or modules that require
paramiko, install the required module :
$ pip install --user paramiko
Ansble can also be installed inside a new or existing
$ python -m virtualenv ansible # Create a virtualenv if one does not already exist $ source ansible/bin/activate # Activate the virtual environment $ pip install ansible
If you wish to install Ansible globally, run the following commands:
$ sudo python get-pip.py $ sudo pip install ansible
sudo will make global changes to the system. Since
pip does not coordinate with system package managers, it could make changes to you system that leave it in an inconsistent on 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.
Packaging Ansible or wanting to build a local package yourself, but don’t want to do a git checkout? Tarballs of releases are available on the Ansible downloads page.
These releases are also tagged in the git repository with the release version.
Ansible is easy to run from source. You do not need
to use it and there is no software to actually install. No daemons
or database setup are required. Because of this, many users in our community use the
development version of Ansible all of the time so they can take advantage of new features
when they are implemented and easily contribute to the project. Because there is
nothing to install, following the development version is significantly easier than most
open source projects.
If you are want to use Ansible Tower as the Control Node, do not use a source installation of Ansible. Please use an OS package manager (like
pip to install a stable version.
To install from source, clone the Ansible git repository:
$ git clone https://github.com/ansible/ansible.git $ cd ./ansible
git has cloned the Ansible repository, setup the Ansible environment:
$ source ./hacking/env-setup
$ source ./hacking/env-setup.fish
If you want to suppress spurious warnings/errors, use:
$ source ./hacking/env-setup -q
If you don’t have
pip installed in your version of Python, install it:
$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py $ python get-pip.py --user
Ansible also uses the following Python modules that need to be installed :
$ pip install --user -r ./requirements.txt
To update ansible checkouts, use pull-with-rebase so any local changes are replayed.
$ git pull --rebase
$ git pull --rebase #same as above $ git submodule update --init --recursive
Once running the env-setup script you’ll be running from checkout and the default inventory file
/etc/ansible/hosts. You can optionally specify an inventory file (see Working with Inventory)
$ echo "127.0.0.1" > ~/ansible_hosts $ export ANSIBLE_INVENTORY=~/ansible_hosts
You can read more about the inventory file in later parts of the manual.
Now let’s test things with a ping command:
$ ansible all -m ping --ask-pass
You can also use “sudo make install”.
