Check if the deployment and data directory permissions are correct.

The issue has been resolved.
Solution:
After changing the external IP to the internal IP in these two files:
/em-deploy/alertmanager-4112/scripts/run_alertmanager.sh
/em-deploy/kibana-4109/conf/kibana.yml
they were able to start normally.

Generally, when encountering this kind of problem, directly check the corresponding service startup logs, and you can find some clues.
