无法在 cenotos7 上将 qpidd 作为守护进程运行

我想在启动时在 centos7 上运行 apache qpidd 作为守护进程，但由于无法锁定文件而失败

如果我使用“service qpidd start”运行它，然后使用“service qpidd status”检查状态，它会返回：

    [root@localhost ~]# service qpidd status
Redirecting to /bin/systemctl status  qpidd.service

在机器启动时也存在同样的问题

来自 /var/log/messages 的日志

文件夹的权限如下，我也尝试将权限设置为 qpidd 用户，但出现同样的问题：

[root@localhost ~]# cd /data/qpid/persistent/
[root@localhost persistent]# ll
