# Install Flight

On every node:

1. Add the flight package:

    sudo yum install -y https://repo.openflighthpc.org/pub/centos/7/openflighthpc-release-latest.noarch.rpm

2. Rebuild the yum cache:

    sudo yum makecache

3. Install the flight packages:

    sudo yum install -y flight-user-suite flight-plugin-systemd-service

4. Start and enable flight:

    systemctl start flight-service
    systemctl enable flight-service

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

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

    flight start
    flight set always on

7. Change the name of the cluster:

    flight config set cluster.name mycluster1

8. 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 yum repolist should display the openflight package. E.g. on head node:

   [root@chead1 ~]# yum repolist
   Loaded plugins: fastestmirror
   Loading mirror speeds from cached hostfile
    * base: mirror.freethought-internet.co.uk
    * epel: epel.mirror.wearetriple.com
    * extras: repo.uk.bigstepcloud.com
    * updates: mirror.mhd.uk.as44574.net
   repo id             repo name                            status
   base/7/x86_64       CentOS-7 - Base                      10,072
   epel/x86_64         Extra Packages for Enterprise Linux  13,750
   extras/7/x86_64     CentOS-7 - Extras                       516
   openflight/7/x86_64 OpenFlight - Base                        81
   updates/7/x86_64    CentOS-7 - Updates                    4,160
   repolist: 28,579

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) ~]#
