Initialize the cluster
----------------------
1. Install Greenplum on all the nodes you will include in your cluster as described in : https://gpdb.docs.pivotal.io/latest/install_guide/prep_os_install_gpdb.html
2. On all nodes, create unix user "gpadmin" as described at https://gpdb.docs.pivotal.io/latest/admin_guide/roles_privs.html . A convenient script for this is in Greenplum source at https://raw.githubusercontent.com/greenplum-db/gpdb/master/concourse/scripts/setup_gpadmin_user.bash
3. Change ownership of gpdb installed files to that gpadmin user, and do all the following initialization as that gpadmin user:
chmod -R gpadmin:gpadmin /opt/gpdb
su - gpadmin
source /opt/gpdb/greenplum_path.sh
4. Follow instructions to initialize cluster at https://gpdb.docs.pivotal.io/latest/install_guide/init_gpdb.html
