Create the Metadata Store User & Stores

A Composer user must be established for the Postgres metadata store.

To create the Composer user for the Postgres metadata store, complete the following steps:

1. For all Linux operating systems, create the Composer user in PostgreSQL. Run the following command:

   sudo -u postgres -H psql -c "CREATE USER <db_username> WITH PASSWORD '<db_password>'"

   Substitute the PostgreSQL user name and password for <db_username> and <db_password>.

2. Create the stores that will hold the Composer metadata, upload data, keyset, and query engine data. Run the following series of commands, substituting the user name for <db_username>:

   sudo -u postgres -H psql -c "CREATE DATABASE\"zoomdata\" WITH OWNER <db_username>"
   
   sudo -u postgres -H psql -c "CREATE DATABASE\"zoomdata-upload\" WITH OWNER <db_username>"
   sudo -u postgres -H psql -c "CREATE DATABASE\"zoomdata-keyset\" WITH OWNER <db_username>"
   sudo -u postgres -H psql -c "CREATE DATABASE\"zoomdata-qe\" WITH OWNER <db_username>"
