Impact on the System

The microservice cannot receive and process requests. As a result, the overall system performance may deteriorate.

Possible Causes

The MicroService Fails To Be Registered


  1. Possible cause 1: Failed to register the microservice.

    1. Use PuTTY to log in to the server where the microservice fails to be registered as user hcp using the IP address reported by the alarm.

      Default account: hcp. Default password: PXU9@ctuNov17!.

    2. Run the su root command. Enter the password of user root to switch to user root.

      The default password of user root is Cloud12#$.

    3. Run the ps -ef | grep microservice name command to check whether the microservice process exists.
    4. Run the netstat -lp | grep microservice port command to check whether the microservice port is occupied.
      • If yes, stop the process that occupies the port. Then go to 1.e.
      • If no, 1.e.
    5. Run the cd /opt/huawei-data-protection/ebackup/microservice/ebk_xxx/script command to go to the microservice script directory. In the command, ebk_xxx indicates the microservice name.
    6. Run the source command to import environmental variables.
    7. Run the stop command to stop the microservice. Wait for 1 minute and the microservice will start automatically.
      • If yes, 1.h.
      • If no, contact technical support engineers.
    8. Wait for a while and check whether the microservice is successfully registered.
      • If yes, no further action is required.
      • If no, 1.i.
    9. Run the service hcp status command to check whether the ebk_governance and ebk_iam microservices are running.
      • If yes, 1.j.
      • If no, refer to 1.e to 1.g to restart ebk_governance or ebk_iam that is not running, and then go to 1.h.
    10. Run the ps -ef | grep ebk_lb command to check whether the nginx process of ebk_lb is running properly.
      • If yes, 1.k.
      • If no, restart ebk_lb by referring to 1.e to 1.g. Then go to 1.h.
    11. Run the cat /opt/huawei-data-protection/ebackup/microservice/ebk_xxx/conf/hcpconf.ini | grep Loadbalance command to obtain the floating IP address.
    12. If the IP address is an IPv4 address, run the ping Floating IP address command. If the IP address is an IPv6 address, run the ping6 Floating IP address command to check whether the network communication of the server where the microservice resides is normal.
      • If yes, contact technical support engineers.
      • If no, rectify the network. Then go to 1.h.
