Post Install

❗️

Before You Start

Please make a full backup of the database before upgrading. If you run into issues, you can restore from the backup.

On Master Node

Step 1
Back up the current <install dir> by making a copy to <install dir>-copy

Step 2
Shut down dependencies and services:

./stopHyprDependencies.sh
./stopHyprServices.sh

Step 3
Switch to the <install dir> and remove the existing WAR files:

rm -f CC/CC-*.jar

Step 4
Un-tar the new <install pkg> (ServerInstaller-*.tar.gz) in the current <install dir>

# Un-tar install pkg, overlay on existing
# Do not overwrite the nginx certs (hyprServer.crt, hyprServer.key)
# HYPR_GROUP:HYPR_USER. The should match the values defined in env.sh 

tar -xvf <install pkg> -C /opt/hypr/<install dir> --group=<HYPR_GROUP> --owner=<HYPR_USER> --exclude="hyprServer*"

This will:

• replace the scripts in the <install dir> with the new versions
• replace the WAR/JAR files for relevant components
• leave the existing config in (mysql/mysql-8.0.18-linux-x86_64-minimal redis/redis-4.0.13 vault/vault-0.10.3) untouched

Step 5
Restore the envOverrides.sh file from the copy made in Step 1.

Step 6
Start dependencies as normal and start services with the reinit-vault flag:

./startHyprServices --[cluster|single] --rp --enc

You should see the following in the output:

✅  Java version 11 available
Generating /opt/hypr/CC/controlCenterConfigV68Plus.properties
...
✅ Finished writing to vault
...
**** Starting CC service. 
...
✅  Port 8009 is listening

Step 8
Reinstall the systemd services. Since UAF is gone, the systemd start order has to be modified:

cd <install folder>;

# Remove
systemdRemove.sh

# Re-install 
systemdInstall.sh

On Each Worker Node

Repeat Steps 1-4 from above.
