# Install Flight

Install flight on a node.

1. Install the OpenFlight release RPM:

   dnf install -y https://repo.openflighthpc.org/openflight/centos/8/x86_64/openflighthpc-release-3-1.noarch.rpm

2. Add the Power Tools repository:

   dnf config-manager --set-enabled powertools

3. Rebuild the dnf cache:

   dnf makecache

4. Install the flight packages:

    dnf install -y flight-user-suite flight-plugin-system-systemd-service

5. Start and enable flight:

    systemctl start flight-service
    systemctl enable flight-service

6. Log out and log back in for the environment to load.

7. Start flight, and enable it on start up:

    flight start
    flight set always on

8. Change the name of the cluster:

    flight config set cluster.name mycluster1

9. Log out and log back in for the environment to reload.

Flight has been installed on this node. Follow the instructions on each node until they all have Flight.

# Testing

If all was successful, then the following should be the case on all nodes:

1. The command dnf repolist should display the openflight and powertools packages. E.g. on head node:

    [root@chead1 ~]# dnf repolist
    repo id            repo name
    appstream          CentOS Stream 8 - AppStream
    baseos             CentOS Stream 8 - BaseOS
    epel               Extra Packages for Enterprise Linux 8 - x86_64
    epel-modular       Extra Packages for Enterprise Linux Modular 8 - x86_64
    extras             CentOS Stream 8 - Extras
    openflight         OpenFlight - Base
    powertools         CentOS Stream 8 - PowerTools

2. The command systemctl status flight-service shows the service as active with no errors.

3. The flight environment should be started (flight start).

4. The command prompt should display the cluster name. E.g.

   [root@chead1 (mycluster1) ~]#
