Puppet Installation and Configuration

Manual Installation of Puppet Puppet is a client / server based application Puppet clients are often referred to as nodes, clients, or hosts The Puppet server is often referred to as the puppetmaster Not:

Manual Installation of Puppet Currently Reductive Labs offers support for the following operating systems: Linux : CentOS, Debian, Fedora, Gentoo, Mandriva, RHEL, Oracle Linux, SUSE, and Ubuntu BSD : FreeBSD, and OpenBSD Other Unix : Mac OS-X, and Sun Solaris Windows : None currently Source: http://docs.puppetlabs.com/guides/platforms.html

Manual Installation of Puppet ,[object Object],[object Object],[object Object],[object Object],[object Object]

Installing Puppet on CentOS / RHEL Ensure that your package manager (yum) is configured to communicate with the EPEL repo. # rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-3.noarch.rpm # yum repolist Should list epel in the left hand column

Installing Puppet on CentOS / RHEL # yum install -y puppet (installs the client) # yum install -y puppet-server (installs the server) # yum install -y facter # yum install -y ruby-doc (optional if you want –help to work with ruby commands) These installs will also process other dependencies such as ruby and ruby-libs
