Opensearch didn't print any log on RHEL

@darkCruel The issue is in the system entropy. RHEL 8 has low entropy, and the OpenSearch 3.x service won’t start.

Docker Image 3.1.1 doesn't seem to work

@yeonghyeonKo Thanks for sharing. My findings were very similar. Low entropy was causing the OS to get stuck. I was testing with docker and binary. In both cases on a single AlamaLinux8 node. Running rngd service increased entropy on the Linux OS. Just sharing the other GitHub issue where you made those comments for traceability.

You can try the following as a workaround

yum install rng-tools
service rngd start
