INTRODUCTION</h2></div></div></div><p>This tutorial is aimed at people learning cdist and shows
|
|||
|
|
typical approaches as well as gives an easy start into
|
|||
|
|
the world of configuration management.</p><p>This tutorial assumes you are configuring <span class="strong"><strong>localhost</strong></span>, because
|
|||
|
|
it is always available. Just replace <span class="strong"><strong>localhost</strong></span> with your target
|
|||
|
|
host for real life usage.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_quick_start_get_your_hands_dirty_now"></a>3. QUICK START - GET YOUR HANDS DIRTY NOW</h2></div></div></div><p>For those who just want to configure a system with the
|
|||
|
|
cdist configuration management and do not need (or want)
|
|||
|
|
to understand everything.</p><p>Cdist uses <span class="strong"><strong>ssh</strong></span> for communication and transportation
|
|||
|
|
and usually logs into the <span class="strong"><strong>target host</strong></span> as the
|
|||
|
|
<span class="strong"><strong>root</strong></span> user. So you need to configure the <span class="strong"><strong>ssh server</strong></span>
|
|||
|
|
of the target host to allow root logins: Edit
|
|||
|
|
the file <span class="strong"><strong>/etc/ssh/sshd_config</strong></span> and add one of the following
|
|||
|
|
lines:</p><pre class="screen"># Allow login only via public key
|
|||
|
|
PermitRootLogin without-password
|
|||
|
|
|
|||
|
|
# Allow login via password and public key
|
|||
|
|
PermitRootLogin yes</pre><p>As cdist uses ssh intensively, it is recommended to setup authentication
|
|||
|
|
with public keys:</p><pre class="screen"># Generate pubkey pair as a normal user
|
|||
|
|
ssh-keygen
|
|||
|
|
|
|||
|
|
# Copy pubkey over to target host
|
|||
|
|
ssh-copy-id root@localhost</pre><p>Have a look at ssh-agent(1) and ssh-add(1) on how to cache the password for
|
|||
|
|
your public key. Usually it looks like this:</p><pre class="screen"># Start agent and export variables
|
|||
|
|
eval `ssh-agent`
|
|||
|
|
|
|||
|
|
# Add keys (requires password for every identity file)
|
|||
|
|
ssh-add</pre><p>At this point you should be able to <span class="strong"><strong><span class="strong"><strong>ssh root@localhost</strong></span></strong></span> without
|
|||
|
|
re-entering the password. If something failed until here, ensure that
|
|||
|
|
all steps went successfully and you have read and understood the
|
|||
|
|
documentation.</p><p>As soon as you are able to login without password to localhost,
|
|||
|
|
we can use cdist to configure it. You can copy and paste the following
|
|||
|
|
code into your shell to get started and configure localhost:</p><pre class="screen"># Get cdist
|
|||
|
|
# Mirrors can be found on
|
|||
|
|
# http://www.nico.schottelius.org/software/cdist/install/#index2h4
|
|||
|
|
git clone git://git.schottelius.org/cdist
|
|||
|
|
|
|||
|
|
# Create manifest (maps configuration to host(s)
|
|||
|
|
cd cdist
|
|||
|
|
echo '__file /etc/cdist-configured' > cdist/conf/manifest/init
|
|||
|
|
|
|||
|
|
# Configure localhost in verbose mode
|
|||
|
|
./bin/cdist config -v localhost
|
|||
|
|
|
|||
|
|
# Find out that cdist created /etc/cdist-configured
|
|||
|
|
ls -l /etc/cdist-configured</pre><p>That’s it, you’ve successfully used cdist to configure your first host!
|
|||

|

|
|||
|
|
to create a more sophisticated configuration.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_see_also"></a>4.
