serviço solr não inicia através do systemctl

Estou instalando o Solr 9.6.1 no Unix seguindo este link e consigo iniciar o serviço por meio do comando abaixo

service solr start

Mas não consigo iniciar o serviço através de systemctl. Ao executar systemctl start solraparece a mensagem abaixo

Job for solr.service failed because the control process exited with error code.
See "systemctl status solr.service" and "journalctl -xeu solr.service" for details.

A execução systemctl status solrfornece a mensagem abaixo
