Around this time last year I blogged about Upgrading my servers to CentOS 7, the post contained a link to a script which I wrote to deploy a Puppet Master & Agent and some updated instructions for installing on RHEL / CentOS 7.
As those instructions no longer work, and I needed to install a Puppet Master to have a play with I decided to update the installation script.
After a little reading it looks like installing a Puppet Master with Apache and Passenger is a little old fashioned since the release of Puppet Server.
The release of Puppet Server made it a lot easier to install a Puppet Master and also it allowed me merge the two scripts (one each for EL6 and EL7) into a single script.
The updated scripts can be found in my GitHub account or to install Puppet Server you can run the following on either clean RHEL / CentOS 6 or 7 installation;
and to install an agent;
curl -fsS https://raw.githubusercontent.com/russmckendrick/puppet-install/master/agent | bash -s puppet.master.com
making sure to replace puppet.master.com with your freshly installed Puppet Server URL.
