This section describes how to install greenplum plugin onto ambari-server.

If your Ambari cluster is a single node cluster, there are some extra steps you'd have to follow

1. Stop ambari-server

2. Make sure you execute setup_repo.sh for both GPDB and gpdb-plugin

   # cd to where GPDB.tar and greenplum-plugin.tar files are extracted
   ./setup_repo.sh
   

3. Install the plugin:

   sudo yum install -y greenplum-plugin
   

4. Single node cluster only Before starting ambari-server, remove GPDBSTANDBY component from metainfo.xml. See Appendix 1

5. Start ambari-server

6. Single node cluster only During Cluster Install Wizard, make sure greenplum.master.port in greenplum-site is changed through Ambari Wizard to 10432 (or anything other than 5432) to avoid a port conflict.

e.g /var/lib/ambari-server/resources/stacks/PHD/3.0/services/GPDB/metainfo.xml
