<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 on the <strong>overlord</strong> machine (the machine that you&#8217;ll be talking to the other 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 running less than Python 2.6, you will also need:</p>
<ul class="simple">
<li>The Python 2.4 or 2.5 backport of the <tt class="docutils literal"><span class="pre">multiprocessing</span></tt> module<ul>
<li><a class="reference external" href="http://code.google.com/p/python-multiprocessing/wiki/Install">Installation and Testing Instructions</a></li>
</ul>
</li>
<li><tt class="docutils literal"><span class="pre">simplejson</span></tt></li>
</ul>
<p>On the managed nodes, to use templating, you will need:</p>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">python-jinja2</span></tt> (you can install this with ansible)</li>
</ul>
</div>
<div class="section" id="developer-requirements">
<h2>Developer Requirements<a class="headerlink" href="#developer-requirements" title="Permalink to this headline"></a></h2>
<p>For developers, you may wish to have:</p>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">asciidoc</span></tt> (for building manpage documentation)</li>
<li><tt class="docutils literal"><span class="pre">python-sphinx</span></tt> (for building content for the ansible.github.com project only)</li>
</ul>
</div>
<div class="section" id="getting-ansible">
<h2>Getting Ansible<a class="headerlink" href="#getting-ansible" title="Permalink to this headline"></a></h2>
<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>You can also clone the git repository yourself and install Ansible in
one of two ways:</p>
<div class="section" id="python-distutils">
<h3>Python Distutils<a class="headerlink" href="#python-distutils" title="Permalink to this headline"></a></h3>
<p>You can also install Ansible using Python Distutils:</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 RPMs 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:</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-1.0-1.noarch.rpm</pre>
</div>
</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>Edit /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 /bin/echo hello</pre>
</div>
<p>Congratulations. You&#8217;ve just contacted your nodes with Ansible. It&#8217;s now time to read some
of the more real-world examples, and explore what you can do with different modules, as well
as the Ansible playbooks language. Ansible is not just about running commands, but you already
have a working infrastructure!</p>
