New MID Server service on linux fails to start if another MID server is already installed on the same host and agent log files are not created.
As documented in the Install a MID Server on Linux, only one MID Server can be installed per host:
However, it is possible to run (not install) more than one MID Server if no MID Servers are installed. The drawback of running MID servers without installing them is that the service will not be started on host restart.
Note: Installation of linux MID server is performed by running:
Confirm linux MID server is installed:
systemctl | grep "mid.service"
Remove references to service:
systemctl stop mid.service
systemctl disable mid.service
Start MID server services
Note: Do not run "./mid.sh install" on this host
