<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’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 rebuilding manpage files)</li>
|
|
<li><tt class="docutils literal"><span class="pre">python-sphinx</span></tt> (for rebuilding content for the ansible.github.com docs project only)</li>

<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>As the project is still pretty new, you will probably just want to clone
|
|
the git checkout instead, so you can keep up with all of the latest features,
|
|
and also contribute easily back to the project (if you want).
|
|
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/">Github project</a> if
|
|
you have a github account. This is also where we keep the issue tracker for sharing
|
|
bugs or feature ideas.</p>

|
<div class="section" id="make-install">
|
|
<h3>Make Install<a class="headerlink" href="#make-install" title="Permalink to this headline">¶</a></h3>
|
|
<p>You can install Ansible using “make install”. This is done through 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-*.noarch.rpm</pre>
|
|
</div>
|
|
<p>If you are tracking the upstream source (i.e. git), the RPM revision may 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.</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>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, but
|
|
you already have a working infrastructure!</p>
