<h2>Requirements<a class="headerlink" href="#requirements" title="Permalink to this headline">¶</a></h2>
|
|
<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>These distributions don’t have Python 2.6 by default, but it is easily installable.</p>

<h2>Getting Ansible<a class="headerlink" href="#getting-ansible" title="Permalink to this headline">¶</a></h2>
|
|
<p>If you are interested in using all the latest features, you may wish to keep up to date
|
|
with the development branch of the git checkout. This also makes it easiest to contribute
|
|
back to the project.</p>
|
|
<p>Instructions for installing from source are below.</p>
|
|
<p>Ansible’s release cycles are about one month long. Due to this
|
|
short release cycle, any bugs will generally be fixed in the next release versus maintaining
|
|
backports on the stable branch.</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 <a class="reference internal" href="patterns.html"><em>Inventory & Patterns</em></a>) 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>RPMs for the last Ansible release are available for <a class="reference external" href="http://fedoraproject.org/wiki/EPEL">EPEL</a> 6 and currently supported
|
|
Fedora distributions.</p>
|
|
<blockquote>
|
|
<div># install the epel-release RPM if needed on CentOS, RHEL, or Scientific Linux
|
|
$ sudo yum install ansible</div></blockquote>
|
|
<p>You can also 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>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 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</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>
