Foreman

Foreman is a host management system for Linux systems.

Installation

Foreman can be installed on most Linux distributions as well as in Docker. This section will go over the steps needed to get Foreman running on one server. However, individual foreman components could be installed on separate machines if desired.

To quickly get started with Foreman, get a clean install of CentOS and install the foreman-installer:

# yum -y install https://yum.puppetlabs.com/puppetlabs-release-pc1-el-7.noarch.rpm && \
yum -y install http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm && \
yum -y install https://yum.theforeman.org/releases/1.15/el7/x86_64/foreman-release.rpm && \
yum -y install foreman-installer

Ensure that the server has the proper hostname. For example, if this server is to be called 'foreman.lab.cpsc.ucalgary.ca', add the following to the hosts file:

192.168.154.129    foreman.lab.cpsc.ucalgary.ca foreman

The foreman-installer will bootstrap the installation process using the puppet classes that are bundled with it with the features that are desired as arguments. To get just foreman installed:

# /usr/sbin/foreman-installer \
                --foreman-servername foreman.lab.cpsc.ucalgary.ca \
                --foreman-serveraliases foreman \
                --foreman-db-type postgresql \
                --foreman-db-username foreman \
                --foreman-db-database foreman \
                --foreman-db-password a4jbdsftsdfrsdfhdfdfPjk7zb \
                --foreman-db-manage   true \
                --enable-foreman \
                --enable-puppet \
                --enable-foreman-plugin-salt \
                --enable-foreman-plugin-discovery \
                --enable-foreman-proxy-plugin-discovery \

# /usr/sbin/foreman-rake db:migrate
# /usr/sbin/foreman-rake db:seed
# /usr/sbin/foreman-rake permissions:reset

The initial setup will take a while. Once this step is complete, you should be able to access the Foreman web interface at https://foreman.lab.cpsc.ucalgary.ca.

The Smart Proxy can be installed using foreman-installer as well. This can be done either on the same foreman server, or on a separate server. The oauth tokens are obtained from the web interface under 'settings' (or probably from foreman-rake somehow?).

# /usr/sbin/foreman-installer \
          --enable-foreman-proxy \
          --foreman-proxy-tftp=true \
          --foreman-proxy-tftp-servername=192.168.154.129 \
          --foreman-plugin-discovery-install-images true \
          --foreman-proxy-dhcp=true \
          --foreman-proxy-dhcp-interface=ens33 \
          --foreman-proxy-dhcp-gateway=192.168.154.2 \
          --foreman-proxy-dhcp-range="192.168.154.10 192.168.154.99" \
          --foreman-proxy-dhcp-nameservers="192.168.154.129" \
          --foreman-proxy-dns=true \
          --foreman-proxy-dns-interface=ens33 \
