Server

In order to run the server, we are using a CentOS7 box.

First the official repo needs to be enabled.

yum install https://yum.puppet.com/puppet6-release-el-7.noarch.rpm -y

Then the server itself installed.

yum install puppetserver -y

Now we want to make sure the service is automatically starting at boot and start it for now.

systemctl start puppetserver
systemctl enable puppetserver

By default the server is set to 2GB of RAM, if you want you can go as low as 512MB. All that is needed is to edit the /etc/sysconfig/puppetserver config file and modify this line.

JAVA_ARGS="-Xms512m -Xmx512m

Let’s add a nice and popular front end called Foreman

yum install https://yum.theforeman.org/releases/2.0/el7/x86_64/foreman-release.rpm  -y
yum install epel-release -y

Now we can install the packages.

yum -y install foreman-release-scl
yum -y install foreman-installer

Finally execute the installer, which will fail unless the output of facter fqdn and hostname -f match.

foreman-installer

You can use the hostnamectl set-hostname <newname> to adjust your hostname!

You should see the following output if everything is successfull!

Preparing installation Done

Now if we login to the specified url the followin scenery welcomes us!
