I am configuring Elasticsearch 2.3.3 (yes, outdated) on CentOS 7.7. We were running it on CentOS 6 with InitV script. I followed this specification to create systemd script and get inspired with the current Elastic sources.
vi /etc/systemd/system/elastic.service
[Unit]
Description=Elasticsearch
Wants=network-online.target
After=network-online.target
[Service]
Type=notify
RuntimeDirectory=elastics
WorkingDirectory=/opt/app/elastic/default/
ExecStart=/opt/app/elastic/default/bin/systemd-entrypoint -d -p ${PID_DIR}/elasticsearch.pid
StandardOutput=journal
StandardError=inherit
TimeoutStopSec=0
KillSignal=SIGTERM
KillMode=process
SendSIGKILL=no
SuccessExitStatus=143
When I start the service, it says that it failed but the process is started and running in fact:
-- Subject: Unit elastic.service has begun start-up
-- Defined-By: systemd
-- Unit elastic.service has begun starting up.
May 20 14:14:31 SE1 systemd[1]: Failed to start Elasticsearch.
-- Subject: Unit elastic.service has failed
-- Defined-By: systemd
-- Unit elastic.service has failed.
-- The result is failed.
May 20 14:14:31 SE1 systemd[1]: Unit elastic.service entered failed state.

How can I fix this issue? The stop does not work either. Thanks
