Setup and run standard installation for RHEL 8/9

After creating your new RHEL 8/9 systems and backing up your files, you can perform a standard installation for RHEL 8/9.

Follow the Installing Tanzu Salt instructions for Postgresql, Redis, RaaS, and Salt-Master on your RHEL 8/9 systems.

Follow these steps for editing your pillar and state file for RHEL 8/9, and applying highstates to your RHEL 8/9 node.

Important:
These installation steps must be performed on the RHEL 7 Salt Master that your new RHEL 8/9 nodes report to.

1. Open the sse_settings.yaml file in the /srv/pillar/sse/ directory and update the following settings with the appropriate values from your environment:

   Update …	To…
   Pg_server	rhel9-postgres
   Redis_Server	rhel9-redis
   Eapi_servers	rhel9-raas (passed in as a list)
   Salt_masters	rhel9-master (passed in as a list)
   pg_endpoint	IP address or DNS name
   pg_port	5432 (this is the default port)
   pg_username	salteapi
   pg_password	abc123
   redis_endpoint	IP address or DNS name
   redis_port	6379 (this is the default port)
   redis_username	saltredis
   redis_password	def456
   eapi_username	root
   eapi_password	salt
   eapi_endpoint	IP address or DNS name
   Customer_id	This is automatically generated. You can generate it with the cat /proc/sys/kernel/random/uuid" command.
   cluster_id	saltmaster_cluster_1 Note: This setting only needs to be updated if you are using a multi-master setup.

2. Save and close the updated sse_settings.yaml file.

3. Edit the Pillar /srv/pillar/top.sls file to add the appropriate minionIDs in these sections:

   • {# Pillar Top File #}
   • {# Define SSE Servers #}
   • {% load_yaml as sse_servers %}
   • -rhel9-raas
   • -rhel9-postgres
   • -rhel9-redis
   • -redis9-master
   • {% endload %}

4. Run the salt \* saltutil.refresh_pillar command to refresh the pillar on all nodes. You can verify that the pillar data is correc by running salt \* pillar.items.

5. From the RHEL 7 Salt Master, apply these states in order:

   1. Postgresql node - salt rhel9-postgres state.sls sse.eapi_database
   2. Redis node - salt rhel9-redis state.sls sse.eapi_cache
   3. RaaS node - salt rhel9-raas state.sls sse.eapi_service
   4. Salt-master node - salt rhel9-master state.sls sse.eapi_plugin

6. Install the RaaS license on the rhel9-raas system. The license file is stored in the /etc/raas/ directory.

   1. Restart the raas service to read the new license using the systemctl restart raas command.

   2. Open a browser and enter the URL for your RaaS Server: https://ip_address_of_raas_server. Log in with username: root and password: salt.

At this point, no minions or masters are shown. The next step is to configure the master plugin for the new RHEL 9 master during migration.
