cdist-tutorial(7) ================= Nico Schottelius NAME ---- cdist-tutorial - a guided introduction into cdist 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 repace **localhost** with your target host for real life usage. QUICK START ----------- 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 -------------------------------------------------------------------------------- As soon as you are able to login without passwort to the target host, 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 chmod 0700 conf/manifest/init # Configure localhost ./bin/cdist config localhost # Find out that cdist created /etc/cdist-configured ls -l /etc/cdist-configured -------------------------------------------------------------------------------- The file 'conf/manifest/init' is usually the entry point for cdist, to find out what to configure on which host. All manifests are essentially shell scripts. Every manifest can use the types known to cdist, which are usually underline prefixed (__). SEE ALSO -------- cdist(1), cdist-type(7), cdist-stages(7)
