Docker Service Status

Use an SSH tool such as Xshell to log in as the video stream cloud phone O&M user (for example, root) to the server where the cloud phone is deployed.
Query the Docker service status.
```
# systemctl status docker
```
If the value of Active is active, the Docker service state is normal. Otherwise, the service state is abnormal.
If the service status is abnormal, run the following command to check the cause of the Docker service startup failure:
```
# dockerd --debug
```
If the fault persists, restart the Docker service (for details, see 4) or contact Huawei technical support.
Restart the Docker service. After the restart, check whether the service status is active. If the restart fails or the service status is not active, contact Huawei technical support.
```
# systemctl daemon-reload
# systemctl restart docker
```
- systemctl daemon-reload: Start the Docker daemon process.
- systemctl restart docker: Restart the Docker service.
