Quick start guide for Foreman on Enterprise Linux

The Foreman installer is a collection of Puppet modules that installs everything required for a full working Foreman setup. It uses native operating system packaging (.rpm or .deb packages) and adds necessary configuration for the complete installation.

Components include the Foreman web UI, Smart Proxy, a Puppet server, TFTP, DNS and DHCP servers. It is configurable and the Puppet modules can be read or run in "no-op" mode to see what changes it will make.

1. Supported operating systems

The following operating systems are supported by the installer, have packages, and are tested for deploying Foreman:

Table 1. Operating systems supported by foreman-installer
Operating System	Architecture	Notes
Enterprise Linux 9	x86_64 only	EPEL is not supported.
Enterprise Linux 8	x86_64 only	EPEL is not supported.

Foreman community advises against using an existing system because the Foreman installer will affect the configuration of several components.

The installation requires 4 GB of memory. For more information, see System Requirements.

The Foreman installer uses Puppet to install Foreman. This guide assumes that you have a newly installed operating system, on which the installer will setup Foreman, a Puppet server, and the Smart Proxy by default.

2. Configuring repositories

Procedure

Enterprise Linux 9
Enterprise Linux 8

Clear any metadata:
```
# dnf clean all
```

Install the foreman-release.rpm package:

# dnf install https://yum.theforeman.org/releases/3.13/el9/x86_64/foreman-release.rpm

Install the puppet-release package.

For Puppet 8:

# dnf install https://yum.puppet.com/puppet8-release-el-9.noarch.rpm

For Puppet 7:

# dnf install https://yum.puppet.com/puppet7-release-el-9.noarch.rpm

Clear any metadata:
```
# dnf clean all
```

Install the foreman-release.rpm package:

# dnf install https://yum.theforeman.org/releases/3.13/el8/x86_64/foreman-release.rpm

Install the puppet-release package.

For Puppet 8:

# dnf install https://yum.puppet.com/puppet8-release-el-8.noarch.rpm

For Puppet 7:

# dnf install https://yum.puppet.com/puppet7-release-el-8.noarch.rpm

Enable the DNF modules:

# dnf module enable foreman:el8

Note

If there is any warning about conflicts with Ruby or PostgreSQL while enabling foreman:el8 module, see Troubleshooting DNF modules in Installing Foreman Server 3.13 on Enterprise Linux. For more information about modules and lifecycle streams on Red Hat Enterprise Linux 8, see Red Hat Enterprise Linux Application Streams Lifecycle.

Verification

Verify that the required repositories are enabled:
```
# dnf repolist enabled
```

3. Installing Foreman server packages

Procedure

Update all packages:
```
# dnf upgrade
```
Install foreman-installer:
```
# dnf install foreman-installer
```

4. Running the Foreman installer

The installation run is non-interactive, but the configuration can be customized by supplying any of the options listed in foreman-installer --help, or by running foreman-installer -i for interactive mode. More examples are described in the Installation Options section. The -v option disables the progress bar and displays all changes.

Procedure

Run the following command:
```
# foreman-installer
```

The script displays its progress and writes logs to /var/log/foreman-installer/foreman.log.
