Warewulf Initialization

System Services

Once Warewulf has been installed and configured, it is ready to be initialized and have the associated system services started. To do this, start by configuring the system services that Warewulf depends on for operation. To do that, run the following command:

# wwctl configure --all

This command will configure the system for Warewulf to run properly. Here are the things it will do:

  • dhcp: (re)Write the DHCP configuration and restart the service from the host template under /etc/dhcpd.conf.ww and enable the system service.

  • hostfile: Update the system’s /etc/hosts file based on the host template /etc/hosts.ww.

  • nfs: Configure the NFS server on the control node as well as the /etc/fstab in the system overlay based on the configuration in /etc/warewulf/warewulf.conf and enable the system service. Also the file /etc/exports.ww from the host template is installed.

  • ssh: Create the appropriate host keys (stored in /etc/warewulf/keys/) and user keys for passwordless ssh into the nodes. Addionally the shell profiles /etc/profile.d/ssh_setup.csh and /etc/profile.d/ssh_setup.sh are installed.

  • tftp: Write the appropriate binary PXE/iPXE blobs to the TFTP root directory and enable the system service.

This command will quickly setup the system services per the Warewulf configuration. Watch this output carefully for errors and resolve them in the configuration portion of this manual.

Warewulf Service

The Warewulf installation attempts to register the Warewulf service with systemd, so it should be as easy to start/stop/check as any other systemd service:

# systemctl enable --now warewulfd

You can also check and control the Warewulf service using the wwctl command line program as follows:

# wwctl server status

Note

If the Warewulf service is running via systemd, restarting stopping, and starting it from the wwctl command may result in unexpected results.

Logs

The Warewulf server logs are by default written to /var/log/warewulfd.log.
