Description
Technical Field
The invention relates to a method for recovering a server downtime state, in particular to a method for recovering a state of a server after the downtime state through a BMC (baseboard management controller), and belongs to the technical field of server control.
Background
The BMC is software which runs when the server AC is powered on and starts, and runs on a separate chip on the server. The BMC is mainly used for detecting the health states of various components (such as a CPU, a memory, a hard disk, a fan, a machine frame and the like) of the server, the running state of the BMC is independent of a server main system, and the BMC is an out-of-band management mode.
The out-of-band network management means that the management of the network is realized through a special network management channel, network management data and service data are separated, and an independent channel is established for the network management data. In the channel, only management data, statistical information, charging information and the like are transmitted, and the network management data is separated from the service data, so that the efficiency and the reliability of network management can be improved, and the security of the network management data can be improved. In-band management means that management control information of a network and bearer service information of a user network are transmitted through the same logical channel; a network management system must manage devices through a service network. If the managed object can not be accessed through the service network, the in-band network management system is invalid. The existing BMC out-of-band management software in the industry has various solutions, and in-band and out-of-band communication can be realized in the forms of LPC or network, so that the BMC can acquire information related in a main system.
At present, the server installation state before downtime is not considered in the restarting control of the BMC on the server, and under the condition that hardware is not abnormal, a server system is simply restarted, and then the service of the server is started in an in-band management mode.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a method for realizing the state recovery of the server after the downtime through a BMC (baseboard management controller), and realize a method for automatically recovering the server to the state before the downtime after the restart.
In order to solve the problems, the invention adopts the technical scheme that: 1. a method for realizing state recovery after server downtime through BMC comprises the following steps:
s01), establishing communication between the BMC and the server system;
s02), the BMC monitors the running state of each service under the server system in real time, and stores the running state of each service under the server system into the BMC for storage;
s03), the BMC performs restart control on the server after monitoring that the server system is down, and starts the services which are started before the down or closes the services which are not started before the down according to the service information before the down stored by the BMC, so that the server system is consistent with the server system before the down.
Further, the BMC monitors and restarts the server system through an Agent program, and the function of the program includes: the method comprises the steps of acquiring service information under a server system in real time, sending the service information of the server system to the BMC, receiving a server control instruction sent by the BMC, and controlling and managing the opening and closing of the service of the server system according to the instruction.
Furthermore, the Agent program runs on the server system and is set to be started up, and the start sequence is put behind all other programs.
Further, in the normal operation process of the system, the Agent program acquires the service information of the main system in real time, and sends the server information to the BMC, and the BMC stores and updates the service information of the system in real time.
Further, if the Agent program finds that the system is in a downtime state, the Agent program is restarted through the BMC, the Agent program starts to operate at the last restart, at the moment, the BMC acquires the service operation state after the system is restarted through the Agent, compares the current server operation state with the service state recorded before the downtime, sends a service starting instruction to the Agent if the fact that the service is not operated after the restart is found, sends a service closing instruction to the Agent if the server system has the service which is being operated and is not in the service operation list before the downtime, until the system service operation state is consistent with the service operation state before the downtime, at the moment, the BMC sends a confirmation instruction that the service state is consistent to the Agent, and then the BMC does not control the main system.
Further, after the running state of the server system is consistent with that before the downtime, the Agent continuously runs, the state is switched to a service detection state, if the Agent finds that the service running state changes, the Agent informs the BMC to update the service running state list, and the BMC updates the service running state list through the acquired information.
The invention has the advantages that: the invention realizes that the server automatically restores the state before downtime after restarting in the mode of the out-of-band network management, and the out-of-band network management separates the network management data from the service data and establishes an independent channel for the network management data, thereby improving the efficiency and the reliability of the network management and being beneficial to improving the safety of the network management data. The method monitors the running state of each service under the server system in real time through the Agent program, realizes restart control through the Agent program after the server is down, can realize state recovery of the server, does not influence the normal work of the server system, and ensures the working efficiency of the server system.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
The embodiment discloses a method for realizing state recovery after the downtime of a server through a BMC (baseboard management controller). And the BMC performs restart control on the server after monitoring the system downtime, and starts or closes the service of the main system through an Agent according to the service information before the system downtime, which is stored by the BMC, so that the service state of the main system is consistent with that before the system downtime.
Specifically, the method comprises the following steps:
s01), establishing a communication protocol between the BMC and the server system, so that at least one communication mode exists between the server main system and the BMC;
s02), the BMC monitors the running state of each service under the server system in real time, and stores the running state of each service under the server system into the BMC for storage;
s03), the BMC performs restart control on the server after monitoring that the server system is down, and starts the services which are started before the down or closes the services which are not started before the down according to the service information before the down stored by the BMC, so that the server system is consistent with the server system before the down.
The application mode of the method is as shown in fig. 1, on the premise of ensuring that the BMC and the server system have a communication mode, firstly, an Agent program is written, that is, the BMC monitors and restarts the server system through the Agent program, and the function of the Agent program includes: the method comprises the steps of acquiring service information under a server system in real time, sending the service information of the server system to the BMC, receiving a server control instruction sent by the BMC, and controlling and managing the opening and closing of the service of the server system according to the instruction.
