Installing the Lightwave Client on a Photon Image and Joining the Client to a Domain

After you have set up a Lightwave domain controller, you can join Photon clients to that domain. You install the Lightwave client first. After the client is installed, you join the client to the domain.

Prerequisites

• Prepare a Photon OS client for the Lightwave client installation.
• Verify that the hostname of the client can be resolved.
• Verify that you have 184 MB free for the Lightwave client installation.

Procedure

1. Log in to your Photon OS client over SSH.

2. Install the Lightwave client by running the following command.

   # tdnf install lightwave-client -y

3. Edit the iptables firewall rules configuration file to allow connections on port 2020 as a default setting.

   The default Photon OS 3.0 firewall settings block all incoming, outgoing, and forwards so that you must configure the rules.

   1. Open the iptables settings file.

      # vi /etc/systemd/scripts/iptables

   2. Add allow information over tcp for port 2020 in the end of the file, save, and close the file.

      iptables -A INPUT -p tcp -m tcp --dport 2020 -j ACCEPT

   3. Run the following command to allow the required connections without restarting the client.

      # iptables -A INPUT -p tcp -m tcp --dport 2020 -j ACCEPT

4. Join the client to the domain by running the domainjoin.sh script and configuring the domain controller FQDN, domain, and the password for the administrator user.

   # domainjoin.sh --domain-controller <lightwave-server-FQDN> --domain <your-domain> --password '<administrator-user-password>

5. In a browser, go to https://*Lightwave-Server-FQDN* to verify that the client appears under the tenants list for the domain.
