Problems solved by technology

[0002] Today's big data operations have their own cluster processing modes, and the algorithms are not uniform
The company's self-developed system does not even have a cluster, which leads to the failure to work normally after the system crashes, affecting the normal execution of big data processing
Moreover, many existing old systems do not consider the high-availability cluster processing scheme, or only use the simple vrrp protocol for high-availability processing
When the control node or network node in the virtualization system stops serving due to various reasons, the system cannot control the computer network function of the virtualization system and can only wait for the service to resume
For the solution using vrrp, generally only two machines execute the hot standby mode, which is prone to split-brain and leads to ip conflicts and cannot serve normally.

Embodiment 1

[0042] Such as figure 1 Shown is a flow chart of a specific embodiment of a cluster election method in the present invention. see figure 1 , the specific steps of a cluster election method in this specific embodiment include:

[0043] S1. When the slave server cannot obtain the heartbeat of the master server, the status of all slave servers is changed to a candidate server, and a voting request is sent to the remaining servers to be selected as the master server.

[0044] Usually, when the system starts or the master server goes offline, the slave server cannot obtain the heartbeat of the master server. At this time, you can give the slave server time to wait for the heartbeat of the master server by presetting a certain time threshold or the number of times the heartbeat of the master server cannot be obtained. When the slave server still cannot obtain the heartbeat of the master server after exceeding a certain time threshold or exceeding a certain number of times (such as...

Embodiment 2

[0052] The invention also provides a cluster election system to realize the high availability scheme of the non-high availability system.

[0053] Such as figure 2 As shown, it is an architecture diagram of a cluster election system in this specific embodiment. see figure 2 In this specific embodiment, a cluster election system specifically includes a server. The server can determine the master server and the slave server through selection or election. When the master server stops the server, the system of the present invention can be used to flush and elect the master server. Provide services. Specifically, the server includes:

[0054] The state change module 110 is used to change the state to a candidate server when the server cannot obtain the heartbeat of the master server; the original state of the server is the state of the slave server, and when the system starts or the master server goes offline, the slave server cannot obtain the heartbeat of the master server ...

Abstract

The invention relates to the field of large data computing, and more specifically relates to a cluster election method and system for large data operations. The method comprises the following steps: when a slave server cannot obtain the heartbeat of a master server, changing the state of the slave server into a candidate server, and sending a voting request of sending the slave server as the master server to the rest servers; when the candidate server receives the votes of the server exceeding a preset threshold number, electing the candidate server as the master server, and changing the state of the candidate server into the master server; when the candidate server waits for the voting result, electing the other servers as the master server, and changing the state of the candidate server into the slave server; and when no candidate server is elected as the master server, sending the voting request again by the candidate server until a candidate server becomes the master server. According to the cluster election method and system, all kinds of application clusters are formed by a distributed voting protocol, so that the system without high availability has high availability.

Description

technical field [0001] The present invention relates to the field of big data computing, and more specifically, to a cluster election method and system for big data computing. Background technique [0002] Today's big data operations have their own cluster processing modes, and the algorithms are not uniform. The company's self-developed system does not even have a cluster, which causes it to fail to work normally when the system crashes, affecting the normal execution of big data processing. Moreover, many existing old systems do not consider the high-availability cluster processing solution, or only use the simple vrrp protocol for high-availability processing. When the control node or network node in the virtualization system stops serving due to various reasons, the system cannot control the computer network function of the virtualization system, and can only wait for the service to resume. For the solution using vrrp, generally only two machines are in hot standby mod...
