Description
Technical Field
The present application relates to the field of complete machine server testing technologies, and in particular, to a backup method and a backup system for a diagnostic server.
Background
In a server manufacturing plant, after various parts of a server are assembled into a complete server, a series of tests including configuration inspection tests, function tests, aging tests and the like are required to be performed on the complete server so as to ensure that the configuration of the complete server meets requirements, the complete server has good functions and stable performance. The whole machine server which needs to be tested is called a testing machine, a series of tests performed by the testing machine is called diagnostic tests, and the machine which initiates the diagnostic tests is called a diagnostic server.
In the process of the diagnostic test, the diagnostic server is used for initiating the diagnostic test to the testing machine according to the performance parameter index of the testing machine and storing a diagnostic test program. Once the diagnostic server fails, the entire test network cannot operate, and therefore the diagnostic server plays a very important role in the diagnostic test of the tester.
The current diagnostic server usually includes two servers, namely a main diagnostic server and a standby diagnostic server, wherein the main diagnostic server is used for performing normal diagnostic tests, and when the main diagnostic server fails, the standby diagnostic server is started, and the standby diagnostic server takes over the work of the main diagnostic server. When the testing machine is normally diagnosed and tested, the main diagnosis server is used for receiving order messages transmitted by an upstream system and storing diagnosis and test programs and diagnosing and testing the testing machine, and the standby diagnosis server is used for backing up the order messages in the main diagnosis server and storing the diagnosis and test programs in time so as to facilitate the main diagnosis server to continue to diagnose and test when the main diagnosis server fails.
However, in the existing backup method of the diagnostic server, although the backup diagnostic server can backup the relevant information in the main diagnostic server in time, since the order message transmitted by the upstream system is received by the main diagnostic server, when the main diagnostic server fails, the backup diagnostic server cannot backup the order transmitted by the upstream system, and thus the diagnostic test cannot be continued. The backup diagnostic server can only be maintained to continuously perform diagnostic tests on the tester by manually inputting orders, so that the seamless switching between the main diagnostic server and the backup diagnostic server cannot be realized by adopting the backup method of the conventional diagnostic server, and the efficiency of the diagnostic tests is not high enough.

Detailed Description
In order to clearly explain the technical features of the present invention, the present application will be explained in detail by the following embodiments in combination with the accompanying drawings. The following disclosure provides many different embodiments, or examples, for implementing different features of the application. In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Further, the present application may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and processes are omitted so as to not unnecessarily limit the application.
For a better understanding of the present application, embodiments of the present application are explained in detail below with reference to the accompanying drawings.
Example one
Referring to fig. 1, fig. 1 is a schematic flowchart of a backup method of a diagnostic server according to an embodiment of the present application. As can be seen from fig. 1, the backup method for a diagnostic server provided in the embodiment of the present application includes the following steps:
s1: and building a diagnosis server. The diagnosis server comprises a main server and a standby server.
Two servers are selected to form a diagnosis server, and the two servers are defined firstly, wherein one server is defined as a main server, and the other server is defined as a standby server.
Specifically, the diagnostic server may be configured as a PXE (Preboot xcxecute Environment) server. The diagnostic server is configured as a PXE server, that is, after operating systems are installed on two servers, services such as tftpboot, dhcp, xinted, ntp and nfs are installed. The diagnostic program and diagnostic database are then stored in the primary server and the backup server.
In the embodiment of the application, because both the main server and the standby server need to have a complete diagnostic test function, when the diagnostic service is configured as the PXE server, the main server and the standby server are both provided with the DHCP service and the THTP service, instead of being respectively provided in the main server and the standby server.
After the diagnosis server is built, the process proceeds to step S2: and setting functions of the main server and the standby server.
In the embodiment of the application, the main server may be configured to allocate an IP to the tester, store a diagnostic test OS and a test program, guide the tester to perform testing, and perform instruction maintenance and component information maintenance, and the standby server is configured to receive order data transmitted by an upstream system. The function is set, so that the standby server is used as an external server for creating an order database; and the main server is used to construct the diagnostic environment. In a normal working state, the standby server is used for receiving order data transmitted by an upstream system, then the main server carries out diagnostic test on the tester according to the order data, and only when the main server breaks down, the standby server is used for carrying out the diagnostic test. The main server bears a large amount of diagnosis workload, so that the probability of the main server failing is much greater than that of the standby server, in the embodiment of the application, the standby server is adopted to receive the order data transmitted by the upstream system, and the main server is not adopted to receive the order data transmitted by the upstream system, so that the condition that the whole diagnosis system cannot continue to perform diagnosis tests due to the failure of the main server can be effectively avoided, and the efficiency of the diagnosis tests can be greatly improved.
S3: and performing real-time file backup and database backup between the main server and the standby server.
In the embodiment, the file backup and the data block backup performed between the main server and the standby server are real-time backups, and the files and the database in the main server can be backed up in the standby server in time, so that seamless switching between the standby server and the main server can be ensured when the main server fails.
The method for performing real-time file backup between the main server and the standby server in the embodiment comprises the following steps: and backing up the storage catalog of the diagnostic test OS, the storage catalog of the test program and the storage catalog of the test log in the main server to the standby server in real time. The method for backing up the real-time database between the main server and the standby server comprises the following steps: the order data received by the standby server is backed up to the main server in real time, and the instruction data and the component data maintained in the main server are backed up to the standby server in real time.
Specifically, the synchronous mirror backup tools sersync and rsync may be used in the primary server and the synchronous tool rsync may be used in the standby server. For example: the folders which the main server needs to synchronize to the standby server are tftpboost/folder for storing the test OS directory and diagshare/folder for storing the test program and the test log, so that the main server can automatically backup the tftpboost/folder and/diagshare/folder to the standby server by writing the sersync configuration files tftpboost.
Further, the file backup and database backup operations in the embodiment of the application adopt a real-time incremental backup mode. That is, after a full backup or a last incremental backup, each backup only needs to backup files that are added or modified compared with the previous backup. The incremental backup method ensures that the main server cannot be synchronized into the standby server when misoperation such as file deletion occurs on the main server, and the backup method is favorable for ensuring the safety of backed-up data and improving the fault tolerance of backup operation.
In addition, in the file backup and database backup operations in the embodiment of the application, the temporary file is not synchronized to the standby server. This is beneficial to improving backup efficiency and saving service resources.
In file backup and data block backup operations, the following backup rules may be employed: backing up operations of creating a folder, finishing creating a file, moving the file, modifying file attributes and modifying file contents; these operations are not backed up for the start of deleting and creating files, and are not backed up for temporary files.
Example two
Referring to fig. 2 based on the embodiment shown in fig. 1, fig. 2 is a schematic flowchart of another backup method for a diagnostic server according to an embodiment of the present disclosure. As can be seen from fig. 2, the backup method according to the embodiment of the present application further includes step S4: and monitoring the real-time file backup operation and the database backup operation between the main server and the standby server.
Specifically, the method for monitoring file backup and database backup operations comprises the following steps:
setting a fixed time, and judging whether the file backup and the database backup are normally carried out between the main server and the standby server by inquiring the process of the operating system at intervals of the fixed time; if yes, continuing to judge every other fixed time; if not, restarting the file backup operation and the database backup operation.
In this embodiment, whether file backup and database backup are normally performed between the main server and the standby server is determined by querying the process of the operating system, which means that whether file backup and database backup are normally performed is determined by querying whether a backup process exists in the process of the operating system.
The setting of the fixed time can be determined according to the use condition of the diagnosis server in practical application. The starting time of the fixed time is usually set when the frequency of the server is not high, for example, the starting time is set to judge whether the real-time file backup operation and the database backup operation between the main server and the standby server are normally performed every morning, and if the real-time file backup operation and the database backup operation are stopped, the backup is started. The fixed monitoring time is set, so that the backup operation can be monitored, the condition of backup interruption can be found in time, the situation that a large amount of system resources are occupied by monitoring can be avoided, and the system resources can be saved.
The method for monitoring the real-time file backup operation and the database backup operation between the main server and the standby server can ensure the effectiveness of real-time backup between the main server and the standby server and avoid the standby server from taking over to perform diagnostic test when the main server fails due to the stop of the backup operation between the main server and the standby server. It is advantageous to further ensure seamless switching between the primary server and the standby server.
Whether the backup operation is normally performed can be periodically monitored by writing a script. For example: and judging whether the file backup and the database backup are normally carried out between the main server and the standby server by adopting a/usr/local/check script, and restarting the backup operation if the file backup and the database backup are not normally carried out, for example, running a sersync background after 5 seconds.
If the monitoring frequency needs to be set, namely fixed time and fixed time interval are set for monitoring, editing can be carried out in the/etc/crontab file of the Linux system in the main server. The/etc/crontab file is a mechanism for the Linux system to specify a fixed time to run a specified script. For example: the fixed time interval is set to be 24 hours, the judgment is carried out once every 6:30, and whether the real-time file backup operation and the database backup operation between the main server and the standby server are normally carried out or not is judged. One line can be added below the/etc/crontab file
306 root/usr/local/check.sh, indicating that the script is executed once/usr/local/check.sh every 6:30 minutes.
The parts of the embodiment not described in detail can refer to the first embodiment shown in fig. 1, and the two embodiments can be referred to each other, and will not be described in detail herein.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a backup system of a diagnostic server according to an embodiment of the present disclosure. As can be seen from fig. 3, the backup system of the diagnostic server in this embodiment mainly includes three parts: the diagnostic server building module, the function setting module and the backup module. The diagnosis server building module is used for building a diagnosis server, and the diagnosis server comprises a main server and a standby server; the function setting module is used for setting functions of the main server and the standby server; the backup module is used for performing real-time file backup and database backup between the main server and the standby server.
In this embodiment, the function setting module includes a main server function setting unit and a standby server function setting unit, where the main server function setting unit is used to set a main server to allocate an IP to a tester, store a diagnostic test OS and a test program, guide the tester to perform a test, and perform instruction maintenance and component information maintenance; the standby server function setting unit is used for setting the standby server to receive order data transmitted by the upstream system.
