The following example describes the most common upgrade situation in which a single Airlock IAM has been installed and can be upgraded with a newer IAM version. We assume, that an instance name auth exists:
copy
# As "root": Stop "auth" instance service systemctl stop airlock-iam-auth # Install new version, e.g. 8.3 ./airlock-iam-installer-8.3.sh su - airlock # Upgrade "auth" instance iam upgrade -i "auth" # Upgrade systemd service for instance "auth" iam systemd -i "auth" # As "root" (ctrl-d): Enable new systemd service pointing to the new IAM version cp '/home/airlock/iam/instances/auth/airlock-iam-auth.service' '/etc/systemd/system/airlock-iam-auth.service' chown root:root '/etc/systemd/system/airlock-iam-auth.service' && chmod 644 '/etc/systemd/system/airlock-iam-auth.service' systemctl enable -f airlock-iam-auth systemctl daemon-reload systemctl start airlock-iam-auth
