#Post Install Guide:

Configure a Puppet Master Server



After installing Puppet on a node that will act as a puppet master server, 

you need to:



    Get the master’s names and certificates set up

    Configure any necessary settings

    Put your Puppet modules and manifests in place

    Configure a production-ready web server

    Configure load balancing and CA service routing if you’re using multiple masters

    Start the puppet master service



#Setup Certificate:



Decide on a main name for Puppet services at your site, and make sure 

your DNS resolves it to the puppet master (or its load balancer). Unconfigured agents 
will try to find a master at puppet, so if you use this name it can reduce setup time.



In the [main] section of the master’s puppet.conf file, set the dns_alt_names setting to 
a comma-separated list of each hostname the master should be allowed to use:



dns_alt_names = puppet,puppet.example.com,scientificlinux.example.com



192.168.56.107  scientificlinux.example.com     scientificlinux puppet

192.168.56.107  puppet.example.com      puppet



#Setup CA





If this is the only puppet master in your deployment, or if it will be acting as the CA server for a multi-master site, you should now run:



$ sudo puppet master --verbose --no-daemonize



#[root@scientificlinux, load: 0.01] (Fri Oct 10 - 20:27:45)
