INTRODUCTION
|
||||
------------
|
||||
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.
|
||||
|
||||
This tutorial assumes you are configuring **localhost**, because
|
||||
it is always available. Just replace **localhost** with your target
|
||||
host for real life usage.
|
||||
|
||||
|

|
||||
QUICK START - GET YOUR HANDS DIRTY NOW
|
||||
--------------------------------------
|
||||
For those who just want to configure a system with the
|
||||
cdist configuration management and do not need (or want)
|
||||
to understand everything.
|
||||
|
||||
Cdist uses **ssh** for communication and transportation
|
||||
and usually logs into the **target host** as the
|
||||
**root** user. So you need to configure the **ssh server**
|
||||
of the target host to allow root logins: Edit
|
||||
the file **/etc/ssh/sshd_config** and add one of the following
|
||||
lines:
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
# Allow login only via public key
|
||||
PermitRootLogin without-password
|
||||
|
||||
# Allow login via password and public key
|
||||
PermitRootLogin yes
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
As cdist uses ssh intensively, it is recommended to setup authentication
|
||||
with public keys:
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
# Generate pubkey pair as a normal user
|
||||
ssh-keygen
|
||||
|
||||
# Copy pubkey over to target host
|
||||
ssh-copy-id root@localhost
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
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:
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
# Start agent and export variables
|
||||
eval `ssh-agent`
|
||||
|
||||
# Add keys (requires password for every identity file)
|
||||
ssh-add
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
At this point you should be able to ***ssh root@localhost*** without
|
||||
re-entering the password. If something failed until here, ensure that
|
||||
all steps went successfully and you have read and understood the
|
||||
documentation.
|
||||
|
||||
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:
|
||||
--------------------------------------------------------------------------------
|
||||
# Get cdist
|
||||
git clone git://git.schottelius.org/cdist
|
||||
|
||||
# Create manifest (maps configuration to host(s)
|
||||
cd cdist
|
||||
echo '__file /etc/cdist-configured' > 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
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
That's it, you've successfully used cdist to configure your first host!
|
||||
Continue reading the next sections, to understand what you did and how
|
||||
to create a more sophisticated configuration.
