MainError:
Caused by: java.security.AccessControlException: access denied ("java.io.FilePermission" "/usr/lib64/libsystemd.so.0" "read")
I cannot find file: /usr/lib64/libsystemd.so.0
Installed elasticsearch v7.9.3 in RedHat 7.1. Followed the steps mentioned at https://www.elastic.co/guide/en/elasticsearch/reference/7.9/rpm.html. Installed using rpm manually and run elasticsearch using systemd command in CLI
