centos - SonarQube 无法在 CentOS 上启动 : systemd returns (code=exited, status=203/EXEC)

Question

关注 https://www.vultr.com/docs/how-to-install-sonarqube-on-centos-7在我的 CentOS 上安装 SonarQube。
当我尝试通过 sudo systemctl start sonar 启动 SonarQube 时它给出以下错误:

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

systemctl status sonar.service 的输出:

status=203/EXEC表示 systemd无法执行 ExecStart脚本。最“流行”的原因是:

脚本路径不正确

脚本具有无效权限:

服务用户无权读取脚本

脚本未标记为可执行

希望 /opt/sonarqube/bin/linux-x86-64/sonar.sh存在，因此请验证该脚本是否标记为可执行。
