Não é possível preparar scripts initd no Centos 7. Eu instalei o JBOSS EAP7 que vem com scripts initd embutidos para iniciar o serviço. Eu começo / paro / reinicio os serviços como o seguinte, que funciona bem. No entanto, quando eu garfo os mesmos scripts initd via systemd não funciona. Qualquer ajuda seria apreciada.
# /opt/jboss/bin/init.d/jboss-eap-rhel.sh start
Starting jboss-eap: /root
[ OK ]
# /opt/jboss/bin/init.d/jboss-eap-rhel.sh status
jboss-eap is running (pid 3024)
# /opt/jboss/bin/init.d/jboss-eap-rhel.sh stop
Stopping jboss-eap: [ OK ]
# /opt/jboss/bin/init.d/jboss-eap-rhel.sh status
jboss-eap is not running
# /opt/jboss/bin/init.d/jboss-eap-rhel.sh start
Starting jboss-eap: /root
[ OK ]
# /opt/jboss/bin/init.d/jboss-eap-rhel.sh status
jboss-eap is running (pid 3314)
Bifurcando os mesmos scripts initd via systemd, dá um erro.

Observação: até tentei especificar o limite de tempo limite na unidade [SERVICE], mas isso ainda não funciona. Sem especificar o limite de tempo, ainda demora muito tempo (1 minuto e 27 segundos). O que poderia estar errado aqui?
Comentários adicionais:
Às vezes começa e às vezes não começa. Como podemos pegar o que falhou?

Nos logs do daemon systemctl, é óbvio que ele está tentando ler o arquivo pid do jboss.
Portanto, primeiro remova seu arquivo pid:
rm /var/run/jboss-eap/jboss-eap-standalone.pid
Agora, comente a linha abaixo e recarregue o daemon:
#PIDFile=/var/run/jboss-eap/jboss-eap-standalone.pid
systemctl daemon-reload
Em seguida, inicie o serviço jboss.
systemctl start jbosseap7
