用户手动重启 Apache 后，systemctl 报告服务失败。无需重启进程，systemd 和 reality 可以同步吗？

我有一个以 systemd 单元启动的 Apache 实例。用户手动停止并重新启动了该实例。现在 systemctl 报告该服务“失败”。除了停止并重新启动 Apache 之外，还有其他方法可以让 systemd 识别出该服务正在运行吗？

这是状态。（我试图隐藏公司信息，所以如果httpd-apache和INT-1没有意义，那是因为我删除了一部分字符串。）

$ systemctl status httpd-apache-int-1.service

这是我的单位文件。
