solr 服务无法通过 systemctl 启动

我正在通过此链接在 Unix 上安装 Solr 9.6.1 ，并且我能够通过以下命令启动该服务

service solr start

但我无法通过以下方式启动服务systemctl。执行时systemctl start solr出现以下消息

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.

执行后systemctl status solr会显示以下信息

× solr.service - Apache SOLR
