Detailed Description
The core of the application is to provide a server cluster management method and related components thereof, which can effectively avoid the situation of data file loss, and a plurality of NFS servers specially used for the NFS function are not required to be arranged, so that the economic cost is reduced, and the waste of server resources is avoided.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a flowchart of a server cluster management method provided by the present application, which is applied to a target server in a server cluster, wherein the target server is any server in the server cluster, and the server cluster management method includes:
s1: acquiring working parameter information of the NFS server, wherein the working parameter information comprises one or two of network state parameters and hardware parameters;
when managing a server cluster, referring to fig. 2, fig. 2 is a schematic structural diagram of a server cluster provided by the present application, in general, a server management system is connected to NFS servers, where the NFS servers are connected to all other common servers in the server cluster, so as to achieve the purpose that the server management system manages all the common servers in the server cluster, specifically, the server management system may be built up from common servers, various executable files are stored in the server management system, and a user sends the executable files to the server management system, and then operates in the server management system to make the server management system send the executable files to the NFS servers and the common servers, so as to manage the common servers, and in addition, the server management system has a file transfer function, so that the purpose that the server cluster communicates with other external devices is achieved through the function; the NFS server may also be built by servers, and the main function of the NFS server is to ensure consistency of data in the server cluster, and after the server management system sends executable files to the NFS server and a common server, the result files generated by the servers are stored in the NFS server, so that when the NFS server fails, the server cluster will lose the medium for storing the result files, which may cause inconsistent data of the server cluster in subsequent use.
Based on this, a certain server in the server cluster may be defined as a target server in advance, where the server is a client server of the NFS server, and when the NFS server works normally, the target server may acquire the working parameter information of the NFS server in real time so that the target server determines whether the NFS server fails.
S2: judging whether the NFS server fails according to the working parameter information of the NFS server;
in order to detect whether the NFS server fails in real time, the target server acquires the working parameter information of the NFS server to determine, where the network state parameters include an IP address and a communication interface of the NFS server, and when the IP address or the interface changes, it may indicate that the connection between the NFS server and the server management system or between the NFS server and the server cluster is disconnected; the hardware parameters may include state information of hardware such as a CPU (Central Processing Unit ) inside the NFS server, a memory, a cache, and a hard disk, and whether hardware failure or damage exists in the hardware is determined by using the state information to determine whether the NFS server fails.
S3: if the NFS server fails, the target server is taken as a new current NFS server.
After the NFS server fails, the servers in the server cluster and the server management system are disconnected from the NFS server, so that the continuity of the NFS function is guaranteed, the target server serves as a new NFS server and is connected with the servers in the server cluster and the server management system, and when the NFS server fails, the target server replaces all the original functions of the NFS server, so that the continuity of the NFS function is realized, and the situation that data files are lost is avoided.
In summary, the target server acquires the working parameter information of the NFS server, where the working parameter information includes one or two of a network state parameter and a hardware parameter, and then determines whether the NFS server fails according to the working parameter information of the NFS server, and if the NFS server fails, the target server is used as a new current NFS server. When the NFS server fails, the target server is used for replacing the NFS server to work as the current NFS server, so that the situation that the data file is lost can be effectively avoided, a plurality of NFS servers specially used for the NFS function are not required to be arranged, the economic cost is reduced, and the waste of server resources is avoided.
Based on the above embodiments:
as a preferred embodiment, after the target server is the new current NFS server, the method further includes:
when an executable file is received, determining an execution mode of the executable file, wherein the execution mode comprises an out-of-band mode and an in-band mode;
when the execution mode of the executable file is an out-of-band mode, generating a first result file corresponding to the executable file;
when the execution mode of the executable file is in-band mode, the executable file is sent to N servers in the server cluster, so that N servers in the server cluster generate N second result files according to the executable file, and N is a positive integer.
In order to improve cluster management efficiency, in the present application, it is considered that network management modes are generally divided into an out-of-band mode and an in-band mode, where the two management modes are determined according to factors such as whether a corresponding executable file occupies network bandwidth and whether the corresponding executable file occupies a server interface when being executed by a certain server, and the execution modes of the executable file that occupies the network bandwidth and occupies the server interface are in-band modes, and the execution modes of the executable file that does not use the network bandwidth and occupies the server interface are out-of-band modes. Based on this, the in-band executable file occupies some resources, and it can be seen that when the amount of data contained in the executable file is large, the performance of the server executing the executable file may be affected, if the current NFS server is used to execute the in-band executable file, since the current NFS server needs to communicate with the server management system and each server, the performance of the current NFS server may be affected, and thus the performance of the entire server cluster may be affected. Based on this, when the executable file is in the out-of-band mode, the current NFS server executes the executable file itself, and when the executable file is in the in-band mode, the executable file is executed by other servers, which can sufficiently improve cluster management efficiency.
As a preferred embodiment, after generating the first result file corresponding to the executable file, the method further includes:
storing the first result file into a storage space of the target server;
after the N servers in the server cluster generate N second result files according to the executable files, the method further includes:
and acquiring N second result files, and storing the N second result files in the storage space of the target server.
In order to ensure the data consistency of the server cluster, in the application, considering that two servers can communicate in practical application, when the servers communicate, the servers can communicate by utilizing the executable file, the instruction file or the task and the like, and also can communicate by utilizing a certain generated result file, so that the result file used when the servers communicate and the certain generated result file are required to be the same file. Based on the method, when the current NFS server receives an executable file in an out-of-band mode, the current NFS server generates a first result file of the executable file and returns the first result file to a server management system, and meanwhile, the current NFS server also stores the first result file generated by the current NFS server; when other servers in the server cluster generate second result files corresponding to executable files in an in-band mode, the current NFS server returns the second result files sent by the servers to the server management system, and meanwhile, the current NFS server also stores the second result files. By storing the first result file and the second result file, the subsequent other servers can be called through the current NFS server when the first result file and the second result file are called, and the data consistency of the server cluster can be ensured.
As a preferred embodiment, after the target server is the new current NFS server, the method further includes:
when the NFS server is detected to resume normal operation, the NFS server is used as a new current NFS server;
and all the first result files and all the second result files stored by the target server are sent to the NFS server.
In order to ensure the synchronism of data, in the present application, considering that the NFS server is a server specially used for implementing the NFS function, and the target server can be regarded as a client of the NFS server or as a replacement of the NFS server, in the case that the NFS server is normal, the NFS server needs to be a server implemented by taking the NFS server as the primary NFS function, so when the failure of the NFS server is repaired, the NFS server is used as a new server for implementing the NFS function, that is, the original work of the NFS server is restored, and the target server originally implementing the NFS function is returned to the client of the NFS server or the location of the replacement. Because the NFS server needs to be maintained after the failure occurs, the NFS server cannot communicate with other servers in the maintenance process of the NFS server, that is, the NFS server cannot acquire data files such as executable files and result files; meanwhile, the original function of the NFS server is realized by the target server, namely, the target server can receive and store the result files, so that after the NFS server is recovered from faults, the target server sends the result files stored by the target server to the NFS server, the result files which cannot be received by the NFS server because of faults are complemented, and the data synchronism between the NFS server and the target server is ensured.
As a preferred embodiment, sending all the first result files and all the second result files stored by the target server itself to the NFS server includes:
determining a fault starting time when the NFS server fails;
determining the fault end time when the NFS server is detected to recover normal operation;
and all the first result files and all the second result files acquired by the target server in the time period from the fault starting time to the fault ending time are sent to the NFS server.
In order to improve efficiency, in the present application, when the result file stored in the target server is sent to the NFS server, considering that the result file stored before the current failure may exist in the result file stored in the target server, for example, the result file stored when the last failure occurs or the result file stored when the user performs file backup, etc., the result file stored before the failure is also typically stored in the NFS server, and it is obvious that if the result file stored before the current failure in the target server is also sent to the NFS server, more sending time is required, and there is a risk of covering the same name file stored in the NFS server by mistake. Based on this, when the target server sends the result file to the NFS server, the target server may record the fault start time and the fault end time of the present fault of the NFS server, so as to determine the fault time period of the NFS server, and the target server only sends all the first result files and all the second result files stored in this time period to the NFS server, which can also complement the result files that the NFS server cannot receive due to the fault, and further shorten the sending time, improve the efficiency, and avoid covering the same name files in the NFS.
As a preferred embodiment, before acquiring the operating parameter information of the NFS server, the method further includes:
judging whether the target server and the NFS server are in the same network segment;
if the network is in the same network segment, the step of acquiring the working parameter information of the NFS server is entered.
In order to ensure communication efficiency, in the application, considering that all servers are usually communicated through a network, and the servers can communicate through a wide area network and a local area network when communicating, when the servers communicate through the wide area network, the communication efficiency, the communication quality and the like among the servers can be influenced by factors such as network fluctuation, network speed and the like, and when the network fluctuation is large or the network speed is low, the communication efficiency and the communication quality among the servers can be reduced, so that the management efficiency of a server management system to a server cluster is reduced; when the server communicates through the local area network, the server is less influenced by external factors, and higher communication efficiency and communication quality can be ensured. Based on this, it can be determined whether the target server and the NFS server are in the same network segment, and if so, it is indicated that the NFS server and the target server are in the same local area network, and when the NFS server fails and the target server replaces the NFS server, it is equivalent to using the NFS server in the same local area network. In addition, if the target server and the NFS server are not in the same network segment, it may be determined that the local area network corresponding to the server management system is based on the IP address of the server management system, and then the idle IP address in the local area network corresponding to the server management system is allocated to the NFS server and the server cluster, so that the NFS server, the server cluster, and the server management system are set in the same network segment. Based on this, by judging whether the target server and the NFS server are in the same network segment, communication efficiency can be ensured.
As a preferred embodiment, if the NFS server does not fail, further comprising:
when the NFS server sends or receives the data file, acquiring the data file;
the data file is stored to the storage space of the target server itself.
In order to ensure data synchronism, in the present application, considering that the NFS server is a server dedicated to implementing the NFS function, and the target server may be regarded as a client of the NFS server or as a replacement of the NFS server, in the case where the NFS server is normal, although the NFS server is a server implemented with the NFS server as the primary NFS function, when the NFS server fails, the target server is required to replace the NFS server. The NFS server stores executable files sent by the server management system to the server cluster and result files sent by the server cluster or the NFS server to the server management system, and the NFS server achieves the purpose of data consistency in the server cluster by storing the executable files and the result files. Based on this, the synchronism of the data can be ensured.
