服务器系统中领导者服务器的确定方法和服务器系统
Abstract:
本发明公开了一种服务器系统中领导者服务器的确定方法和服务器系统，其中，该确定方法包括：通过至少一轮提名在多个服务器中确定领导者服务器，其中，在每一轮提名中，一服务器向服务器系统中的其他服务器发送提名消息，提名消息用于供其他服务器判断是否同意发送该提名消息的服务器成为领导者服务器；如果在一轮提名中，发送提名消息的服务器未被确定为领导者服务器，则由不同意该服务器成为领导者服务器的一服务器在下一轮提名中向其他服务器发送提名消息；其中，在一服务器发送提名消息后，如果系统中的其他全部服务器、或超过预定数量的服务器均同意该发送提名消息的服务器成为领导者服务器，则将该发送提名消息的服务器确定为领导者服务器。
Abstract(English):

The invention discloses a method for determining a leader server in a server system and the server system. The method for determining the leader server includes the steps that the leader server is determined in multiple servers through at least one round of nomination, in each round of nomination, one server sends a nomination message to other servers in the server system, and the nomination message is used for other servers to judge whether the server sending the nomination message becomes the leader server or not; if the server sending the nomination message in the round of nomination is not determined to be the leader server, the server not agreeing that the server becomes the leader server sends a nomination message to other servers in the next round; after the server sends the nomination message, if all other servers or the servers exceeding a preset number in the system agree that the server sending the nomination message becomes the leader server, the server sending the nomination message is determined to be the leader server.
