Meanwhile, the restart of the storage software can cause various states in the storage software to be changed, so that the time for establishing a new TCP connection with the client is longer, and particularly for a part of protocols which do not support reconnection, the service can be continued only by carrying out manual operation again. Software restarts cause service interruptions that affect user experience.
In summary, how to effectively solve the problem of service interruption caused by software restart is a technical problem that needs to be solved urgently by those skilled in the art.

Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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.
The first embodiment is as follows:
referring to fig. 1, fig. 1 is a flowchart of an access service recovery method according to an embodiment of the present invention, where the method includes the following steps:
and S101, monitoring the stored software.
The monitoring of the storage software can be performed by accessing the storage software or recording input and output data of the storage software. The monitoring content comprises the following steps: storing the running state of the software and storing the service provided by the software. The running state comprises an opening state and a closing state of the storage software. For example, if the storage software cannot be accessed, it is determined that the storage software is in the closed state, and if the storage software can be accessed, it is determined that the storage software is in the open state. Of course, other common software monitoring methods can be used to monitor the operating state of the stored software.
In the embodiment of the present invention, before the storage software is restarted, the TCP connection information corresponding to the target access service and the file state information corresponding to the TCP connection information may be stored in the nonvolatile memory. That is, monitoring the stored software may specifically include:
step one, acquiring the current running state of the storage software, and judging whether the storage software is restarted or not;
and step two, acquiring the TCP connection information and the file state information, and storing the TCP connection information and the file state information into a nonvolatile memory.
For convenience of description, the first step and the second step will be described in combination.
The step one and the step two are not required to be executed sequentially, that is, the step one may be executed first, the step two may be executed first, or the steps may be executed simultaneously. Preferably, an acquisition frequency may be set, and step one is performed continuously, so that the restart of the stored software is detected in time. That is, the execution of the step one can be repeated for a plurality of times, and the current operation state of the storage software can not be acquired after the storage software is determined to be restarted. And for the second step, the TCP connection state and the file state information corresponding to the target access service are obtained only after the second step is executed. The non-volatile memory is a non-volatile memory (NVM), which refers to a computer memory where stored data does not disappear after the current is turned off, and the NVM is classified into two major products, namely ROM and Flash memory, depending on whether the data in the NVM can be rewritten at any time when the computer is used. In the embodiment of the invention, both the ROM and the Flash memory can be used for storing TCP connection information and file state information.
Of course, in order to make the TCP connection information and the file status information in the non-volatile memory in the latest state, the step two may be continuously executed until the software is restarted and the TCP connection information and the file status information of the target access service cannot be obtained. Certainly, in the non-volatile memory, TCP connection information and state information in a file corresponding to a plurality of different periods of the target access service may also be stored, so that when the target access service is recovered, the state of the target access service meeting the current requirement may be selected to be recovered. For example, if a malicious attack or no operation occurs before the storage software is restarted, which causes an exception to the target access service, at this time, in order to enable the recovered target access service to be in a normal state, TCP connection information and file state information corresponding to a plurality of different periods of the target access service may be stored.
In order to obtain TCP connection information, the TCP connections described in the embodiment of the present invention may be all TCP connections established by using a DPDK (intel data plane Development Kit). Before acquiring TCP connection information and file state information, establishing a TCP connection of a target access service by using a DPDK; the TCP connection is a connection between the storage software and the client. The application program of the DPDK runs on a user space, and transmits and receives data packets by using a data plane library provided by the application program, so that the processing process of the data packets by a Linux kernel protocol stack is bypassed. The Linux kernel regards the DPDK application program as a common user mode process, and the compiling, connecting and loading modes of the DPDK application program are not different from those of the common program. TCP connection is established through DPDK, a Linux kernel can be bypassed, and TCP connection information can be obtained directly in a user space.
When the second step is executed, acquiring TCP connection information and file state information, specifically monitoring TCP data transmitted on a TCP connection, and recording TCP connection information; the TCP connection information comprises a TCP communication sequence number and a communication port; and monitoring the file opening operation of the storage software to obtain the file state information. That is, the TCP communication sequence number and the communication port can be obtained by monitoring the TCP data transmitted over the TCP connection, and how to obtain the TCP communication sequence number and the communication port from the TCP data may refer to the TCP communication protocol, which is not described herein again. And monitoring the file opening operation of the storage software to obtain the file state information.
Preferably, in order to reserve enough storage space to store the TCP connection information and the file state information of the access service to be recovered, after the TCP connection information and the file state information are stored in the non-volatile memory, a closing request of the TCP connection may be received, and the TCP connection information and the file state information in the non-volatile memory may be updated. The updating described herein may specifically be to organize a plurality of TCP connection information and file status information of the TCP connection, and only retain the TCP connection status and file status information before closing the TCP connection, so as to recover the access service corresponding to the TCP connection when the TCP close request is an error operation.
S102, after the storage software is monitored to be restarted, reading TCP connection information corresponding to the target access service stored in the nonvolatile memory and file state information corresponding to the TCP connection information.
After the storage software is monitored to be restarted, the TCP connection information corresponding to the target access service and the file state information corresponding to the TCP connection information can be read from the nonvolatile memory. The TCP connection information is information that is necessary to transmit data through a TCP connection, such as a TCP communication sequence number and a communication port. The target access service can be an access service provided by the storage software to any client, and the access service can be a common data storage service, data query, modification and other services. The file state information includes information of files that need to be opened to provide the target access service.
It should be noted that, in the embodiment of the present invention, the reason for restarting the storage software is not limited, that is, the storage software may be upgraded and restarted; or after the server is powered off, the storage software is restarted.
After the TCP connection information and the file state information are read, the operation of step S103 may be performed.
S103, determining a file to be adjusted by using the file state information, and performing state adjustment on the file to be adjusted so that the storage software recovers the target access service by using the TCP connection information.
After the file state information is read, the file state information can be utilized to determine the file to be adjusted, and then the state of the file to be adjusted is adjusted. The file state information includes files to be opened for providing the target access service. And performing state adjustment on the file to be adjusted, namely opening the file to be adjusted. Of course, in practical applications, it may also involve closing a file to provide a target access service. Determining a file to be adjusted and adjusting the file to be adjusted, specifically, acquiring the current state of a file corresponding to file state information in storage software, and determining the file to be adjusted which is not matched with the file state information; and performing state adjustment on the file to be adjusted so as to match the current file state with the file state information.
Preferably, if none of the files in the initial state is in the closed state after the storage software is restarted, the file corresponding to the open state in the file state information may be directly determined as the file to be adjusted, that is, the current state of the file does not need to be acquired.
After the adjustment of the file state is completed, the current file state can be matched with the file state information, namely, the state of the file is restored to the state before the storage software is restarted or the state corresponding to the target access service. At this point, the storage software can recover the target access service using the TCP connection information. Specifically, data interaction can be performed by connecting the TCP established before the restart to the client. Thus, the target access service can be quickly restored after the software is restarted.
The method provided by the embodiment of the invention is applied to monitor the stored software; after the storage software is monitored to be restarted, reading TCP connection information corresponding to a target access service stored in a nonvolatile memory and file state information corresponding to the TCP connection information; and determining a file to be adjusted by using the file state information, and performing state adjustment on the file to be adjusted so that the storage software recovers the target access service by using the TCP connection information.
And monitoring the storage software, and when detecting that the storage software is restarted, changing various states in the storage software. That is, the connection information of the TCP connection for externally providing the target access service and the file state information, which are stored in the kernel by the storage software before the restart, are lost. And the storage software can not provide the TCP connection established before any more to provide access service to the outside without TCP connection information and corresponding file state information. Since the nonvolatile memory has a characteristic that stored data does not disappear after the current is turned off. Therefore, even after the storage software is restarted, the storage data in the nonvolatile memory still exist. At this time, the TCP connection information corresponding to the target access stored in the non-volatile memory and the file state information corresponding to the TCP connection information may be read. The file state information is used for adjusting the state of the file in the storage software, so that the file state of the storage software can be adjusted to the state before the storage software is restarted. Based on the TCP connection information, the storage software can continue to use the TCP connection established before, and recover the target access service by using the file after the state adjustment, namely, the user access can be responded quickly. That is to say, before the software is restarted, the TCP connection information and the file state information corresponding to the target access service are stored in the nonvolatile memory, and after the software is restarted, the access service before the software is restarted can be quickly restored, so that the user connection is not interrupted, the service is continuously provided for the user, and the user experience is improved.
Example two:
in order to better understand the technical solution provided by the embodiment of the present invention, a specific application scenario of recovering the access service after upgrading the stored software will be taken as an example, and the technical solution provided by the embodiment of the present invention will be described in detail below.

The purpose is to directly recover TCP connection when the next startup and ensure that data transmission and reception are continued according to the last state.
Upgrading the control assembly: and the process control is carried out on the system upgrading, so that the consistency of the upgrading state is ensured.
The file real-time information management component: the file opening and operation states are written into the nonvolatile memory in real time, so that the file opening state can be recovered in real time when software is started next time after being upgraded, the file states are consistent, and the system response is timely.
Before software upgrading, when operations such as TCP connection access, file operation tasks, TCP receiving and sending and the like exist, the real-time state is updated to the nonvolatile memory, and the real-time performance and consistency of data updating are guaranteed.
And after the software is upgraded and restarted, recovering the state from the nonvolatile memory, particularly recovering the TCP connection state, the serial number and the file opening state. After the TCP and the file are respectively recovered, the service can be continuously provided for the client, and the service of the client is ensured not to be interrupted.
Specifically, the TCP connection can be realized by using the DPDK in the storage software, and the connection information of the network communication is stored in the nonvolatile memory, and the state of the file is stored in the nonvolatile memory in the file operation process; after the upgrade of the storage software is completed, the TCP connection state and the file state need to be recovered from the nonvolatile memory.
The method adopts a nonvolatile memory to store the TCP connection state and the file state, and the implementation process comprises the following steps:
the method comprises the following steps: receiving TCP connection, and storing connection information to a nonvolatile memory;
step two: receiving TCP data, and storing a TCP communication sequence number to a nonvolatile memory;
step three: receiving file opening operation, storing file information to a nonvolatile memory, and continuously receiving TCP data;
step four: and receiving a TCP closing request, and updating the TCP state information in the nonvolatile memory.
After the software is upgraded successfully, recovering the TCP connection state and the file state from the nonvolatile memory, wherein the implementation process comprises the following steps:
the method comprises the following steps: reading TCP information from the nonvolatile memory and reconstructing TCP connection information;
step two: and reading the file opening information in the nonvolatile memory, and rebuilding the file opening information.
After the TCP connection and the file state are recovered, the client can wait for the service access of the client and provide the access service.

That is, the connection information of the TCP connection for externally providing the target access service and the file state information, which are stored in the kernel by the storage software before the restart, are lost. And the storage software can not provide the TCP connection established before any more to provide access service to the outside without TCP connection information and corresponding file state information.
