Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
At present, when a main machine and a standby machine are synchronously configured in a hot standby scene of the two machines, the quantity of files needing to be sent is large, so that the communication flow between the main machine and the standby machine is large, and the heartbeat stability between the main machine and the standby machine is influenced; in addition, the host and the standby need to perform a large amount of file processing, which occupies a high CPU resource, so that the synchronization efficiency is low, and the stability and performance of the device are also reduced. Therefore, the configuration synchronization scheme is provided, and the configuration synchronization efficiency and the equipment performance in the dual-computer hot standby scene can be improved.
Referring to fig. 1, an embodiment of the present application discloses a first configuration synchronization method, which is applied to a master control device, and includes:
s101, if the configuration synchronization condition is met, comparing the local file identification set with the backup file identification set received recently to determine the configuration file to be synchronized, which is stored in the main control device but not stored in the backup control device.
The local file identification set comprises file identifications corresponding to at least one configuration file stored in the main control equipment; the backup file identification set comprises file identifications corresponding to at least one configuration file stored in the backup control device. The configuration file may be a file regarding network configuration or a file regarding security policy.
In one embodiment, configuring the synchronization condition includes: receiving a backup file identification set sent by the backup control device, or receiving an operation instruction for modifying the configuration file.
When receiving a backup file identifier set sent by a standby control device, a master control device may perform a comparison between a local file identifier set and a recently received backup file identifier set to determine a to-be-synchronized configuration file stored in the master control device but not stored in the standby control device; and sending the configuration file to be synchronized to the standby control equipment so that the standby control equipment can execute the synchronization operation of the configuration file to be synchronized, thereby realizing configuration synchronization.
When receiving an operation instruction for modifying the configuration file, the main control device may compare the local file identifier set with the most recently received backup file identifier set to determine a configuration file to be synchronized, which is stored in the main control device but not stored in the backup control device; and sending the configuration file to be synchronized to the standby control equipment so that the standby control equipment can execute the synchronization operation of the configuration file to be synchronized, thereby realizing configuration synchronization. Therefore, when the configuration file on the main control equipment is modified, the synchronous operation is triggered, and the synchronization is finished in real time.
It should be noted that the two configuration synchronization conditions, that is, "receiving the backup file identifier set sent by the standby control device" and "receiving the operation instruction for modifying the configuration file" may exist at the same time, so that the synchronization process performed by the backup control device is equivalent to the checking operation, and the configuration files that are not synchronized in time may be checked in time.
In a specific embodiment, before comparing the local file identification set with the recently received backup file identification set, the method further includes: calculating the MD5 value corresponding to each configuration file stored in the local synchronization list of the main control equipment; and arranging the obtained MD5 values into a list to obtain a local file identification set. The MD5 values in the local file identification set and the backup file identification set are arranged in a fixed order, so each MD5 value has a fixed MD5 value sequence number. Where the MD5 value is the file identification of a certain file. Of course, other characteristic information of the file can also be used as the file identifier of the file, such as: the CRC32 value of the file, etc.
It should be noted that the configurations in the standby control device and the main control device are not exactly the same, but are mostly the same, and these same configurations only need to ensure that the standby control device and the main control device can be replaced with each other to execute the same service. Therefore, some configuration files which do not need to be synchronized to the standby control device may exist in the main control device, so that a local synchronization list is stored in the main control device, and the local synchronization list includes files which need to be synchronized. The files to be synchronized correspond to the MD5 values in the local file identification set one by one. Generally, the number of the configuration files to be synchronized currently is less than or equal to the number of the files in the local synchronization list.
In a specific embodiment, if the local file identifier set and the backup file identifier set include a comparison identifier, comparing the local file identifier set with the most recently received backup file identifier set to determine a to-be-synchronized configuration file that is stored in the master control device but not stored in the slave control device, includes: determining a target file with the same comparison identification in the local file identification set and the backup file identification set; and if the MD5 values of the target file in the local file identification set and the backup file identification set are not consistent, determining the target file as the configuration file to be synchronized. The comparison marks correspond to the files one by one.
Specifically, the object file is a configuration file (the configuration file is synchronized, but modified in the master control device) that is stored in the master control device and the slave control device at the same time but has a different MD5 value, so that the object file stored in the master control device needs to be transmitted to the slave control device based on the configuration file stored in the master control device, so that the slave control device replaces the object file stored in itself.
In one embodiment, the comparison identifier includes an MD5 value sequence number or an MD5 value corresponding path. That is, when comparing the local file identification set with the newly received backup file identification set, the master device substantially compares the MD5 value serial number or MD5 value corresponding path in the local file identification set and the backup file identification set.
It should be noted that the storage paths of the same configuration file in the master device and the backup device are the same, so that the corresponding MD5 values have the same path, and therefore, when the MD5 values representing the same file are the same in the corresponding paths in the local file identifier set and the backup file identifier set, it indicates that the related files are also the same. Because the MD5 values in the local file id set and the backup file id set are arranged in a fixed order, the MD5 value sequence numbers correspond to one another in the local file id set and the backup file id set, and therefore when the MD5 values representing the same file are the same in the local file id set and the backup file id set, it indicates that the related files are also the same.
S102, sending the configuration file to be synchronized to the standby control equipment so that the standby control equipment can execute the synchronization operation of the configuration file to be synchronized.
In a specific embodiment, sending the configuration file to be synchronized to the standby control device, so that the standby control device performs a synchronization operation of the configuration file to be synchronized, includes: packing the configuration files to be synchronized to obtain a file package; and sending the file packet to the standby control equipment so that the standby control equipment decompresses the file packet and then executes the synchronization operation of the configuration file to be synchronized. And the files are sent after being packed, so that the data transmission quantity can be reduced, and the transmission efficiency is improved.
The standby control equipment and the main control equipment communicate by using a VRRP protocol, and the master and standby machines are switched by using the VRRP protocol. The method for switching the main machine and the standby machine by utilizing the VRRP protocol specifically comprises the following steps: and determining the host and the standby according to the weight value configured by the VRRP protocol or the IP address of the two devices. Such as: the host with a large weight or IP address and the standby with a small weight or IP address. When the host fails or is manually triggered to switch, the host sends a message to the standby machine by using a VRRP protocol, the standby machine switches the host into the host after receiving the message, and the host switches the standby machine into the standby machine. The host is the main control device, and the standby device is the standby control device.
In a specific embodiment, the method further comprises the following steps: receiving a viewing instruction input by a user or a modification instruction aiming at a target configuration file; and displaying the configuration information included in the corresponding configuration file according to the viewing instruction, or updating the target configuration file according to the modification instruction. The user can add, delete, change, check and the like to the configuration file in the main control device, but the configuration file in the standby control device can only be checked, namely can only be read and cannot be modified.
As can be seen, after receiving the backup file identifier set sent by the standby control device, the main control device in the embodiment of the present application compares the local file identifier set with the backup file identifier set, thereby determining the to-be-synchronized configuration file that is stored in the main control device but not stored in the standby control device; the master control device only sends the part of the configuration file to be synchronized to the standby control device so that the standby control device executes the synchronization operation. According to the method and the device, the file transmission quantity and the communication flow between the master control device and the standby control device are reduced, and the heartbeat stability between the master control device and the standby control device is guaranteed. In addition, in the synchronization process, the master control device and the standby control device process the file identifiers, so that the file processing amount in the synchronization process can be reduced, the occupation amount of CPU resources of the master control device and the standby control device can be reduced, and the synchronization efficiency and the device performance can be improved.
Referring to fig. 2, an embodiment of the present application discloses a second configuration synchronization method, which is applied to a standby control device, and includes:
s201, if the sending condition is met, sending the backup file identification set to the main control device, so that the main control device compares the local file identification set with the recently received backup file identification set to determine the configuration file to be synchronized, which is stored in the main control device but not stored in the backup control device.
The local file identification set comprises file identifications corresponding to at least one configuration file stored in the main control equipment; the backup file identification set comprises file identifications corresponding to at least one configuration file stored in the backup control device. The configuration file may be a file regarding network configuration or a file regarding security policy.
S202, receiving the configuration file to be synchronized sent by the main control equipment, and executing the synchronization operation of the configuration file to be synchronized.
In one embodiment, the transmission condition includes every preset time or after completion of the synchronization operation. That is, after every preset time period, the backup control device sends a backup file identifier set to the main control device; or after the backup control device completes the synchronous operation, the backup file identification set is sent to the master control device.
The preset time may be in milliseconds, such as 1 millisecond, 3 milliseconds, etc. Specifically, a timing task may be set, and each time the timing time is reached, the backup control device sends a backup file identifier set to the main control device.
In a specific embodiment, before sending the backup MD5 value list to the master device, the method further includes: calculating an MD5 value corresponding to each configuration file stored in a local synchronization list of the standby control equipment; and arranging the obtained MD5 values into a list to obtain a local file identification set.
In a specific embodiment, if the local file identifier set and the backup file identifier set include a comparison identifier, executing a synchronization operation of the configuration file to be synchronized includes: and determining the file to be updated according to the comparison identifier, and updating the file to be updated into the received configuration file to be synchronized. The configuration file to be synchronized sent by the master control device is the latest file of the file to be updated in the master control device, so that the synchronization can be completed by replacing the file to be updated with the configuration file to be synchronized.
Specifically, determining the file to be updated according to the comparison identifier includes: and determining files with the same comparison identification as the configuration files to be synchronized in the standby control equipment, wherein the files are the files to be updated.
In a specific embodiment, the method further comprises the following steps: receiving a viewing instruction input by a user; and displaying the configuration information included in the corresponding configuration file according to the viewing instruction. The user can only search the configuration file in the standby control equipment, namely, the configuration file can only be read and cannot be modified.
It should be noted that the implementation steps in this embodiment are the same as or similar to those in the above embodiments, and therefore, the description of this embodiment is omitted here.
As can be seen from the above, after the backup control device in this embodiment sends the backup file identifier set to the master control device, the master control device may compare the local file identifier set with the most recently received backup file identifier set to determine the to-be-synchronized configuration file that is stored in the master control device but not stored in the backup control device; and the standby control equipment receives the configuration file to be synchronized sent by the main control equipment and executes the synchronization operation of the configuration file to be synchronized, so that the file transmission quantity and the communication flow between the main control equipment and the standby control equipment are reduced, and the heartbeat stability between the main control equipment and the standby control equipment is ensured. In addition, in the synchronization process, the master control device and the standby control device process the file identifiers, so that the file processing amount in the synchronization process can be reduced, the occupation amount of CPU resources of the master control device and the standby control device can be reduced, and the synchronization efficiency and the device performance can be improved.
Referring to fig. 3, the embodiment of the present application discloses a third configuration synchronization method, which mainly includes: the host and the standby machine compare whether the files are different by exchanging the MD5 values of the files, so that the incremental synchronization of the files is realized.
It should be noted that dual-server hot-standby refers to a solution, and for important services, two servers are used to backup each other and execute the same service together. When one server fails, the other server can undertake the service task, so that the system can be automatically ensured to continuously provide the service without manual intervention.
MD5 is known as Message-Digest Algorithm 5, a widely used cryptographic hash function that generates a 128-bit (16-byte) hash value to ensure the integrity of the Message transmission. The value of MD5 is equivalent to the ID of the file, its value is unique. If the file has been modified (e.g., an embedded virus, Trojan horse, etc.), its MD5 value will change. Of course, modification of the normal contents of the file may also result in a change in the value of MD 5.
The third configuration synchronization method disclosed in this embodiment includes the following specific steps:
(1) initializing a configuration synchronization process of a host machine and a standby machine, and negotiating main control and standby control;
(2) the negotiation is a main control device, and the user can modify the configuration of the device; the negotiation is controlled equipment, and the user can only check the configuration of the equipment and cannot modify the configuration;
(3) the standby control equipment starts a cycle timing task, calculates MD5 values of all files needing to be synchronized, and sends an MD5 value list to the main control equipment;
(4) the master control equipment receives the MD5 list of the slave control equipment and calculates the MD5 values of all files needing to be synchronized; and compare out the different files of MD 5;
(5) the master control equipment packages and sends files with different MD5 values to the standby control equipment;
(6) and the standby control equipment receives the file sent by the main control equipment and executes configuration synchronization operation.
If the user makes any configuration modification on the main control device, the MD5 values of the main and standby files will be different, and the above process can implement the configuration synchronization of the main and standby devices.
It should be noted that the implementation steps in this embodiment are the same as or similar to those in the above embodiments, and therefore, the description of this embodiment is omitted here.
As can be seen, in this embodiment, the primary and secondary machines in the dual-machine hot-standby scenario perform detection of configuration file modification by comparing MD5 values of files, thereby implementing incremental synchronization of configuration files and reducing performance loss of the dual-machine device in configuration synchronization.
In the following, a configuration synchronization apparatus provided by an embodiment of the present application is introduced, and a configuration synchronization apparatus described below and a configuration synchronization method described above may be referred to with each other.
Referring to fig. 4, an embodiment of the present application discloses a configuration synchronization apparatus, which is applied to a master control device, and includes:
