<h2>Requirements<a class="headerlink" href="#requirements" title="Permalink to this headline">¶</a></h2>
|
|
<p>Requirements for Ansible are extremely minimal.</p>
|
|
<p>If you are running python 2.6 or later on the <strong>overlord</strong> machine (the machine
|
|
that you’ll be talking to the remote machines from), you will need:</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> (for playbooks)</li>
|
|
</ul>
|
|
<p>If you are only running Python 2.5, you will also need:</p>
|
|
<ul class="simple">
|
|
<li>The Python 2.5 backport of the <tt class="docutils literal"><span class="pre">multiprocessing</span></tt> module (<a class="reference external" href="http://code.google.com/p/python-multiprocessing/wiki/Install">see here</a>)</li>
|
|
<li><tt class="docutils literal"><span class="pre">python-simplejson</span></tt></li>
|
|
</ul>
|
|
<p>If you have any managed-nodes with python older than 2.6, you will also need:</p>
|
|
<ul class="simple">
|
|
<li><tt class="docutils literal"><span class="pre">python-simplejson</span></tt></li>
|
|
</ul>
|
|
<p>On the managed nodes, to use templates, you will also need:</p>
|
|
<ul class="simple">
|
|
<li><tt class="docutils literal"><span class="pre">python-jinja2</span></tt> (you can easily install this using ansible, and this will not be required in version 0.3 as templates will be evaluated locally)</li>

<h2>Getting Ansible<a class="headerlink" href="#getting-ansible" title="Permalink to this headline">¶</a></h2>
|
|
<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
|
|
rpm <cite>-Uvh</cite> with <cite>–force</cite> when RPM tells you the package is still at the
|
|
same version. This is perfectly safe to do.</p>
|
|
</div>
|
|
<div class="section" id="other-package-distributions">
|
|
<h3>Other Package Distributions<a class="headerlink" href="#other-package-distributions" title="Permalink to this headline">¶</a></h3>
|
|
<p><a class="reference external" href="https://github.com/uu/ubuilds">Gentoo eBuilds are here</a></p>
|
|
<p>Debian packages are in progress.</p>
|
|
<p>If you would like to package Ansible for Homebrew, BSD, or others,
|
|
please stop by the mailing list and say hi.</p>
|
|
</div>
|
|
<div class="section" id="tagged-releases">
|
|
<h3>Tagged Releases<a class="headerlink" href="#tagged-releases" title="Permalink to this headline">¶</a></h3>
|
|
<p>Tagged releases are available as tar.gz files from the Ansible github
|
|
project page:</p>
|
|
<ul class="simple">
|
|
<li><a class="reference external" href="https://github.com/ansible/ansible/downloads">Ansible/downloads</a></li>
|
|
</ul>
|
|
<p>At this point in Ansible’s development, running or building from checkout is preferred
|
|
if you want access to all of the latest modules and improvements.</p>
|
|
</div>
|
|
</div>
|
|
<div class="section" id="your-first-commands">
|
|
<h2>Your first commands<a class="headerlink" href="#your-first-commands" title="Permalink to this headline">¶</a></h2>
|
|
<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>
|
|
<div class="highlight-python"><pre>192.168.1.50
|
|
aserver.example.org
|
|
bserver.example.org</pre>
|
|
</div>
|
|
<p>Set up SSH agent to avoid retyping passwords:</p>
|
|
<div class="highlight-python"><pre>ssh-agent bash
|
|
ssh-add ~/.ssh/id_rsa</pre>
|
|
</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>
