< p > Requirements for Ansible are extremely minimal.< / p >
< p > Ansible is written for Python 2.6. If you are running Python 2.5 on an “ Enterprise Linux” variant,
your distribution can easily install 2.6 (see instructions in the next section). Newer versions
of Linux and OS X should already have 2.6.< / p >
< p > In additon to Python 2.6, you will want the following packages:< / p >
< ul class = "simple" >
< li > < tt class = "docutils literal" > < span class = "pre" > paramiko< / span > < / tt > < / li >
< li > < tt class = "docutils literal" > < span class = "pre" > PyYAML< / span > < / tt > < / li >
< li > < tt class = "docutils literal" > < span class = "pre" > python-jinja2< / span > < / tt > < / li >
< / ul >
< p > On the managed nodes, you only need Python 2.4 or later, but if you are are running less than Python 2.6 on them, you will
also need:< / p >
< ul class = "simple" >
< li > < tt class = "docutils literal" > < span class = "pre" > python-simplejson< / span > < / tt > < / li >
< / ul >
< p > NOTE: Ansible 0.4 will have ways to remote bootstrap this, using Ansible itself. Stay tuned.< / p >

< p > As the project is still pretty new, you will probably want to clone
the git checkout, so you can keep up with all of the latest features,
and also easily contribute back to the project (if you want).< / p >
< p > Instructions for installing from source are below.< / p >
< p > You may also wish to follow the < a class = "reference external" href = "https://github.com/ansible/ansible" > Github project< / a > if
you have a github account. This is also where we keep the issue tracker for sharing
bugs and feature ideas.< / p >
< div class = "section" id = "running-from-checkout" >
< h3 > Running From Checkout< a class = "headerlink" href = "#running-from-checkout" title = "Permalink to this headline" > ¶< / a > < / h3 >
< p > Ansible is trivially easy to run from a checkout, root permissions are not required
to use it:< / p >
< div class = "highlight-python" > < pre > $ git clone git://github.com/ansible/ansible.git
$ cd ./ansible
$ source ./hacking/env-setup< / pre >
< / div >
< p > You can optionally specify an inventory file (see doc:< cite > patterns< / cite > ) other than /etc/ansible/hosts:< / p >
< div class = "highlight-python" > < pre > $ echo "127.0.0.1" > ~/ansible_hosts
$ export ANSIBLE_HOSTS=~/ansible_hosts< / pre >
< / div >
< p > Now let’ s test things:< / p >
< div class = "highlight-python" > < pre > $ ansible all -m ping --ask-pass< / pre >
< / div >
< / div >
< div class = "section" id = "make-install" >
< h3 > Make Install< a class = "headerlink" href = "#make-install" title = "Permalink to this headline" > ¶< / a > < / h3 >
< p > If you are not working from a distribution where Ansible is packaged yet, you can install Ansible
using “ make install” . This is done through < cite > python-distutils< / cite > :< / p >
< div class = "highlight-python" > < pre > $ git clone git://github.com/ansible/ansible.git
$ cd ./ansible
$ sudo make install< / pre >
< / div >
< / div >
< div class = "section" id = "via-rpm" >
< h3 > Via RPM< a class = "headerlink" href = "#via-rpm" title = "Permalink to this headline" > ¶< / a > < / h3 >
< p > In the near future, pre-built packages will be available through your
distribution. Until that time, you can use the < tt class = "docutils literal" > < span class = "pre" > make< / span > < span class = "pre" > rpm< / span > < / tt > command to
build an RPM you can distribute and install:< / p >
< div class = "highlight-python" > < pre > $ git clone git://github.com/ansible/ansible.git
$ cd ./ansible
$ make rpm
$ sudo rpm -Uvh ~/rpmbuild/RPMS/noarch/ansible-*.noarch.rpm< / pre >
< / div >
< p > Note that if you are tracking the upstream source (i.e. git), the RPM revision will not be
bumped with every source code change. To get around this, you can use
< tt class = "docutils literal" > < span class = "pre" > rpm< / span > < span class = "pre" > -Uvh< / span > < / tt > with < tt class = "docutils literal" > < span class = "pre" > --force< / span > < / tt > when RPM tells you the package is still at the
same version. This is perfectly safe to do.< / p >

< p > An Arch PKGBUILD is available on < a class = "reference external" href = "https://aur.archlinux.org/packages.php?ID=58621" > AUR< / a >
If you have python3 installed on Arch, you probably want to symlink python to python2.:< / p >

project page:< / p >
< ul class = "simple" >
< li > < a class = "reference external" href = "https://github.com/ansible/ansible/downloads" > Ansible/downloads< / a > < / li >

< p > Now that you’ ve installed Ansible, it’ s time to test it.< / p >
< p > Edit (or create) /etc/ansible/hosts and put one or more remote systems in it, for
which you have your SSH key in < tt class = "docutils literal" > < span class = "pre" > authorized_keys< / span > < / tt > :< / p >

< p > Set up SSH agent to avoid retyping passwords:< / p >

< / div >
< p > Now ping all your nodes:< / p >
< div class = "highlight-python" > < pre > ansible all -m ping< / pre >
< / div >
< p > Now run a live command on all of your nodes:< / p >
< div class = "highlight-python" > < pre > ansible all -a "/bin/echo hello"< / pre >
< / div >
< p > Congratulations. You’ ve just contacted your nodes with Ansible. It’ s
now time to read some of the more real-world < a class = "reference internal" href = "examples.html" > < em > Command Line Examples< / em > < / a > , and explore
what you can do with different modules, as well as the Ansible
< a class = "reference internal" href = "playbooks.html" > < em > Playbooks< / em > < / a > language. Ansible is not just about running commands, it
also has powerful configuration management and deployment features. There’ s more to
explore, but you already have a fully working infrastructure!< / p >
