Install
Just do a basic install using ubuntu-18.04.3-live-server-amd64.iso
Prevent Floppy Errors
If your server does not have a floppy, Ubuntu will report errors. This can be prevented by preventing the loading of a floppy driver on the clients:
echo "blacklist floppy" | sudo tee /etc/modprobe.d/blacklist-floppy.conf sudo rmmod floppy sudo update-initramfs -u
Enable Netowrking
The first time I built my VM, networking didn't install correctly. If this happens, create a netplan in /etc/netplans (note that because it's YAML, indentation is important)
network:
version: 2
renderer: networkd
ethernets:
ens160:
dhcp4: true
Apply the netplan
sudo netplan apply
Verify that it worked
ifconfig
Host Name Setup
Ensure the Hostname is Set Correctly
sudo hostnamectl set-hostname puppet.bpopp.net
Modify the /etc/hosts file:
127.0.0.1 localhost 192.168.1.42 puppet.bpopp.net # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters
Install Foreman
Install Puppet
sudo apt-get -y install ca-certificates cd /tmp && wget https://apt.puppet.com/puppet6-release-bionic.deb sudo dpkg -i /tmp/puppet6-release-bionic.deb
There appear to be issues with puppet 6 and newer versions of foreman. Puppet 5 may work better:
wget https://apt.puppetlabs.com/puppet5-release-xenial.deb sudo dpkg -i puppet5-release-xenial.deb sudo apt update
Enable Foreman
echo "deb http://deb.theforeman.org/ bionic 1.22" | sudo tee /etc/apt/sources.list.d/foreman.list echo "deb http://deb.theforeman.org/ plugins 1.22" | sudo tee -a /etc/apt/sources.list.d/foreman.list sudo apt-get -y install ca-certificates wget -q https://deb.theforeman.org/pubkey.gpg -O- | sudo apt-key add -
Install
sudo apt-get update && sudo apt-get -y install foreman-installer
Run
sudo foreman-installer \ --enable-foreman-proxy \ --foreman-proxy-tftp=true \ --foreman-proxy-tftp-servername=192.168.1.42 \ --foreman-proxy-dhcp=true \ --foreman-proxy-dhcp-gateway=192.168.1.1 \ --foreman-proxy-dhcp-nameservers="192.168.1.1" \ --foreman-proxy-dhcp-range="192.168.1.150 192.168.1.175" \
Add the Puppetmaster as Host
Seems to be helpful to restart the puppetmaster after installing. To add the puppetmaster as a host, run this from the master:
sudo /opt/puppetlabs/bin/puppet agent --test
Now add our first module:
sudo /opt/puppetlabs/bin/puppet module install puppetlabs/ntp
Import the module from foreman:
- Click Configure > Classes
- Select "Any Organization" and "Any Location" from the menus in the menubar at the top
- Click the "Import environments from puppet" button
- Check the box next the module and click the "Update" button
Configure Foreman
- Click Infrastructure > Subnets > Create Subnet
- Use the following settings:
- Name: bpopp.net
- Network address: 192.168.1.0
- Network Prefix: 24
- Network Mask: 255.255.255.0
- Gateway Address: 192.168.1.1
- Primary DNS: 192.168.1.1
- Boot Mode : DHCP
- In the tabs:
- Under Domain tab, select bpopp.net
- Under Proxies tab, select the puppet.bpopp.net proxies for DHCP, TFTP, and HTTPBoot
- From Locations and Organizations, select Default Location/Organization
Configure Provisioning
For a CentOS box:
- Click Hosts > Operating Systems > Create Operating System
- Use the following settings:
- Name: CentOS
- Major Version: 7
- Family: RedHat
- Architecture: x86_64
- From the tabs
- In the partition table, select 'Kickstart default'
- In the installation Media, select 'CentOS Mirror'
Create a Host Group
Host groups are used to quickly provision/configure servers of a specific type. For example, you can define a host group for Apache webservers that have all the correct modules installed for that specific type of server.
