In the Minion installation section of the Meridian Installation document, it tells you to install the incorrect Minion repository and package. Here is the link to the installation guide that the customer was using:
In "Step 1", the incorrect repository is given. The customer should be using the same repository that they would use for their Meridian installation.
The following line should be updated to the customer's Meridian repository:
The yum/dnf commands for the package installation are also incorrect. Instead of the following:
dnf -y install opennms-minion
yum -y install opennms-minion
They should be:
dnf -y install meridian-minion
yum -y install meridian-minion
This matters because the ActiveMQ topic names are different between Horizon and Meridian.
Let me know if I can give anymore information.
