Problems solved by technology

Therefore, dual-machine hot backup is not seamless and uninterrupted, but it can guarantee that in the event of a system failure, the normal service can be restored quickly, and the business will not be affected. It will be greatly reduced, especially during the live broadcast of some important conferences. Once the main server fails, our system is required to restore the system to the normal state in the shortest possible time

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 In the described embodiment, a kind of heartbeat-based dual-computer hot backup method includes two directors and a live server, the director is connected to the live server, and the core of each director includes two parts, heartbeat monitoring Part and resource takeover part, specifically include the following steps:

[0027] (1) The heartbeat monitoring part is carried out through the wireless network card link. The main broadcaster sends messages regularly to tell the standby broadcaster its current status; specifically: when performing heartbeat detection through IP, the active and standby dual broadcasters will pass the heartbeat path (TCP / IP protocol) periodically sends out detection test packets. When the system is normal, the main broadcaster provides live broadcast services for the system, and the standby bro...

Abstract

The invention discloses a dual-computer hot standby method based on heartbeat. The system comprises two director machines and a live broadcast server, wherein the director machines are connected withthe live broadcast server. The core of each director machine comprises two parts, namely a heartbeat monitoring part and a resource takeover part. The method specifically comprises the steps that (1)the heartbeat monitoring part is carried out through a wireless network card link, and the main director machine sends a message at regular time to tell the standby director machine of the current state of the main director machine; and (2) if the heartbeat message sent by the main director machine is not received within the specified time, the fact that the opposite side has a fault is considered, and the resource takeover part on the standby director machine is started to take over the live broadcast service running on the main director machine and push the live broadcast service to a live broadcast server. The method has the beneficial effects that the normal live broadcast service can be recovered quickly; the main / standby switching time is short; the speed is high; automatic switchingis realized without manual intervention; uninterrupted real-time operation of the live broadcast service is ensured; and the safety and the real-time performance of the live broadcast are guaranteed.

Description

technical field [0001] The invention relates to the technical field related to data processing, in particular to a heartbeat-based dual-computer hot backup method. Background technique [0002] The dual-machine hot backup system is an important technology in the high-availability field. The high availability of data and the continuous operation capability of the system are extremely important. The server is an important device for enterprises and institutions to store data. If it fails to operate normally due to a server failure, It will cause the business to stop, and the failure of the server may be caused by various reasons, such as equipment failure, operating system failure, software system failure and so on. Generally speaking, when technicians are on site, it may take several minutes, hours or even days to restore the server to normal. From practical experience, unless the server is simply restarted (the hidden danger may still exist), it often takes several minutes. ...
