Abstract

A host server electronically connects to one or more agent servers via one or more network ports. Each agent server includes a control module and an agent service that is available to one or more clients. The host server requests the control module and the agent service in an agent server to start each other and monitor running of each other. When the agent service in the agent server needs to be updated, the host server requests the control module to suspend the agent service and write updated data into the agent service to update the agent service. Furthermore, the host server requests the control module to restart the updated agent service.

Claims

1. A method being executed by a processor of a host server for updating an agent service in an agent server, the host server being electronically connected to one or more agent servers via one or more network ports, and each agent server comprising a control module and the agent service, the method comprising:

(a) requesting the control module and the agent service to start each other and monitor running of each other by sending a first command, via pre-assigned network ports, to the agent server by the host server;

(b) requesting the control module to suspend the agent service in the agent server by sending a second command to the agent server via the pre-assigned network ports by the host server; and

(c) requesting the control module to write updated data into the agent service in the agent server by sending a third command to the control module via the pre-assigned network ports by the host server.

2. The method of claim 1, further comprising:

(d) requesting the control module to restart the agent service in the agent server by sending a fourth command to the control module via the pre-assigned network ports by the host server.

3. The method of claim 1, wherein the updated data are received from a first storage device and stored in a second storage device of the host server.

4. The method of claim 1, after step (a) and before step (b) further comprising:

receiving reply information sent by the control module and/or the agent service, wherein the reply information is in relation to whether the control module or the agent service in the agent server runs normally and restart information of the control module and/or the agent service.

5. The method of claim 4, wherein the restart information comprises restart reasons, restart times, and time for beginning restart operations of the control module and/or the agent service.

6. A method being executed by a processor of an agent server for updating an agent service, the agent server being electronically connected to a host server via one or more network ports, and the agent server comprising a control module and the agent service, the method comprising:

(a) in response to receiving a first command, sent by the host server via pre-assigned network ports, the control module and the agent service start each other and monitor running of each other;

(b) in response to receiving a second command, sent by the host server via the pre-assigned network ports, suspending the agent service in the agent server by the control module; and

(c) in response to receiving a third command, sent by the host server via the pre-assigned network ports, writing updated data into the agent service by the control module.

7. The method of claim 6, further comprising:

(d) in response to receiving a fourth command, sent by the host server via the pre-assigned network ports, restarting the agent service in the agent server by the control module.

8. The method of claim 6, after step (a) and before step (b) further comprising:

sending a first reply to the host server by the agent server, wherein the first reply comprises information in relation to whether the control module or the agent service in the agent server runs normally and restart information of the control module and/or the agent service.

9. The method of claim 6, wherein the restart information comprises restart reasons, restart times, and time for beginning restart operations of the control module and/or the agent service.

10. The method of claim 6, after step (b) and before step (c) further comprising:

sending a second reply to notify the host server that the agent service has been suspended by the control module.

11. A non-transitory computer-readable medium having stored thereon instructions that, when executed by a processor of a host server, which is electronically connected to at least one agent server comprising a control module and an agent service, via one or more network ports, cause the host server to perform operations of:

(a) requesting the control module and the agent service in an agent server to start each other and monitor running of each other by sending a first command, via pre-assigned network ports, to the agent server by a management module of the host server;

(b) requesting the control module to suspend the agent service in the agent server by sending a second command to the agent server via the pre-assigned network ports by the management module; and

(c) requesting the control module to write updated data into the agent service in the agent server by sending a third command to the control module via the pre-assigned network ports by the management module.

12. The non-transitory medium of claim 11, wherein the operations further comprise:

(d) requesting the control module to restart the agent service in the agent server by sending a fourth command to the control module via the pre-assigned network ports by the management module.

13. The non-transitory medium of claim 11, wherein the updated data are received from a first storage device and stored in a second storage device of the host server.

14. The non-transitory medium of claim 11, after the operation (a) and before the operation (b) further comprising:

receiving reply information sent by the control module and/or the agent service, wherein the reply information is in relation to whether the control module or the agent service in the agent server runs normally and restart information of the control module and/or the agent service.

15. The non-transitory medium of claim 14, wherein the restart information comprises restart reasons, restart times, and time for beginning restart operations of the control module and/or the agent service.

16. A non-transitory computer-readable medium having stored thereon instructions that, when executed by a processor of an agent server, which comprises a control module and an agent service and electronically connects a host server via one or more network ports, cause the agent server to perform operations of:

(a) in response to receiving a first command, sent by the host server via pre-assigned network ports, the control module and the agent service start each other and monitor running of each other;

(b) in response to receiving a second command, sent by the host server via the pre-assigned network ports, suspending the agent service in the agent server by the control module; and

(c) in response to receiving a third command, sent by the host server via the pre-assigned network ports, writing updated data into the agent service by the control module.

17. The non-transitory medium of claim 16, wherein the operations further comprise:

(d) in response to receiving a fourth command, sent by the host server via the pre-assigned network ports, restarting the agent service in the agent server by the control module.

18. The non-transitory medium of claim 16, after the operation (a) and before the operation (b) further comprising:

sending a first reply to the host server by the agent server, wherein the first reply comprises information in relation to whether the control module or the agent service in the agent server runs normally and restart information of the control module and/or the agent service.

19. The non-transitory medium of claim 16, wherein the restart information comprises restart reasons, restart times, and time for beginning restart operations of the control module and/or the agent service.

20. The non-transitory medium of claim 16, after the operation (b) and before the operation (c) further comprising:

sending a second reply to notify the host server that the agent service has been suspended by the control module.
