The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It should be noted that the terms "first," "second," and the like are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, the present application provides a server 10, where the server 10 is deployed with a Web system, and may be used to provide Web services.
Web system: the Web application program or the system is provided through the Web service, a user accesses the Web service content through the terminal browser, and the user completes corresponding work or task through the interactive operation of the page in the terminal browser.
Web service: refers to a web service provided by the server 10 according to a transmission protocol for access by a terminal browser. The transport protocol may be hypertext transport protocol (Hypertext Transfer Protocol, HTTP) or hypertext transport security protocol (Hyper Text Transfer Protocol over SecureSocket Layer, HTTPs).
In this embodiment, the server 10 may include a processing module 11 and a storage module 12. The storage module 12 stores a computer program which, when executed by the processing module 11, enables the server 10 to perform the steps in the active-standby system switching method described below.
In this embodiment, the server 10 may further include other modules, for example, the server 10 may further include a communication module 13 for establishing a communication connection with other devices. For example, the server 10 may establish a communication connection with a user terminal or other server through the communication module 13. The user terminal may be, but is not limited to, a smart phone, a personal computer.
The processing module 11, the storage module 12 and the communication module 13 are electrically connected directly or indirectly to each other to realize data transmission or interaction. For example, the modules may be electrically connected to each other via one or more communication buses or signal lines.
Referring to fig. 2, the present application further provides a primary and backup system 20, which may include a primary server 30 and a backup server 40, where the primary server 30 and the backup server 40 may be configured as the server 10 shown in fig. 1. Both the primary server 30 and the backup server 40 are deployed with a Web system as a HA (high availability) dual-computer cluster system.
In the primary and backup systems 20, web services can be provided through the primary server 30 or the backup server 40. The operation modes of the primary and secondary systems 20 may include a primary mode and a secondary mode.
When operating in the primary mode, the Web system of the primary server is running, and the backup server is typically in a standby state, i.e., the Web system of the backup server is in a shutdown state. When operating in the standby mode, the Web system of the standby server operates, and the main server is usually in a standby state, i.e., the Web system of the main server is in a shutdown state.
When the switching between the main mode and the standby mode is needed, the main server and the standby server can be matched with each other, and each step in the main and standby system switching method can be realized.
Referring to fig. 3, the present application further provides a method for switching between a primary system and a secondary system, which may be applied to the primary system and the secondary system, and may be implemented by mutually cooperating a primary server and a secondary server in the primary system and the secondary system, where the method may include the following steps:
step S110, when a main server acquires a main-standby switching instruction, monitoring the working state of a Web system in a standby server according to a preset period;
and step S120, when the working state indicates that the Web system of the standby server completes the current start, switching the address for providing the Web service from the address of the main server to the address of the standby server so as to provide the Web service by the standby server.
In the above embodiment, the first Web service in the main server may periodically monitor the working state of the Web system of the standby server, and then perform the main-standby switching when the Web system of the standby server completes the startup, and then the standby server provides the Web service. In this way, in the primary-backup switching process, the primary server can timely detect whether the Web system of the backup server is started, so that the automatic switching of the primary-backup system can be timely realized, and a user does not need to manually detect whether the Web system of the backup server is started, thereby being beneficial to improving the efficiency of primary-backup switching and improving the user experience.
The steps of the method will be described in detail below, as follows:
in step S110, the master-slave switching instruction is used by the master-slave system to switch the master server to the slave server, so that the slave server replaces the master server to execute the corresponding service. The mode of the main server obtaining the main and standby switching instructions can be flexibly determined according to actual conditions.
For example, the primary server may receive a primary-standby switching instruction sent by the external device. For example, the user sends the active/standby switching instruction to the active/standby service area through the browser of the user terminal, and at this time, the active/standby switching instruction sent by the user terminal can be obtained by the active/standby server.
For another example, the primary server may automatically generate the primary-standby switching instruction when the switching condition is satisfied, and at this time, the primary server may acquire the primary-standby switching instruction. The switching conditions can be flexibly set according to actual conditions. For example, when the main server needs to perform a software upgrade, or when there is an abnormality, it is determined that the switching condition is satisfied.
In the main server, a preset function is prestored through a JavaScript program, and the preset function is used for acquiring the working state of the Web system in the standby server according to a preset period, instead of acquiring the working state of the Web system in the standby server through Ajax.
JavaScript is a lightweight, interpreted, or just-in-time programming language with functional preference, and its script program can run in a browser.
Ajax is a network messaging method applied to web pages and is well known to those skilled in the art.
When the master server acquires the master-slave switching instruction, the working state of the Web system in the slave server can be monitored through a preset function according to a preset period based on the JavaScript program, for example, the time stamp of the completion of starting of the Web system is monitored.
Understandably, the monitored operating state includes, but is not limited to, a timestamp of completion of start-up of the Web system in the backup server, a timestamp of shutdown or shutdown of the Web system. The preset period can be flexibly determined according to practical situations, and is not particularly limited herein.
After the main server obtains the working state of the Web system from the standby server, the working state can be analyzed to determine whether the Web system of the standby server is started currently. The current start refers to the start of the Web system after the master server acquires the master-slave switching instruction.
In step S120, if the Web system completes the current startup, it means that the Web system in the backup server completes the startup after the primary server obtains the primary-backup switching instruction, and at this time, the address for providing the Web service is switched from the address of the primary server to the address of the backup server, so that the primary-backup switching can be implemented. The Web service is then provided by the backup server. The address of the standby server may be stored in the main server in advance.
In the present embodiment, in the main server, a first Web service based on the HTTP protocol is created in advance; and a second Web service based on the HTTP protocol is pre-created in the standby server, and the access address of the second Web service is used for returning the starting time of the Web system of the standby server when the second Web service is accessed. When the access address of the first Web service is accessed, page information may be returned. The page information may be a static page.
Understandably, the backup server can store time information of the Web system in the backup server when the start-up or stop operation is completed. For example, the backup server may store time information when the Web system completes startup in a designated file of the backup server, which may be flexibly determined or created, which is not particularly limited herein. The second Web service provided by the standby server may read the content in the specified file, so that when the access address of the second Web service is accessed, a timestamp of the time when the start-up of the Web system is completed may be returned to the accessing party (such as the main server).
Based on the first Web service and the second Web service, step S110 may include:
and creating a preset tag according to the preset period through the preset function in the main server to acquire the content in the access address of the second Web service, wherein the content comprises the starting time stored by the Web system of the standby server when the starting is completed.
Wherein creating, by the preset function in the main server, a preset tag at the preset period to obtain content in an access address of the second Web service, includes:
creating a preset tag with the preset period through the preset function in the main server, wherein the preset attribute of the preset tag is the access address of the second Web service;
and loading the preset tag into the Web page of the main service to acquire the content in the access address corresponding to the preset attribute.
In this embodiment, the preset tag may be a Script tag, and the preset attribute may be a Src attribute of the tag. Where the Script tag is one of HTML (HyperText Markup Language ) tags, it can be used to embed a scripting language (e.g., javaScript) or to import an external scripting file (e.g., javaScript file). The Src attribute is one attribute in the Script tag, and can be used to import an external Script file (e.g., javaScript Script file). The Src attribute may be used to set an address of an external script, such as an access address to add the second Web service in the present embodiment.
Because the access address of the second Web service is accessed, the timestamp stored by the Web system in the standby server when the start is completed can be returned, and therefore, the timestamp stored by the Web system when the start is completed can be accessed in the mode of HTTP request by loading the preset label on the Web page of the main server. In the access process, if the Web system is not started, the time stamp in the designated file is not read. At this time, the steps of creating the preset tag and loading the preset tag into the Web page of the main service to obtain the content in the access address corresponding to the preset attribute are repeatedly performed in a preset period until the Web system is started, and the timestamp recorded in the specified file when the Web system is started can be read.
As an alternative embodiment, before step S110, the method may further include:
and receiving the active/standby switching instruction generated by clicking a virtual button.
Understandably, in the Web service provided by the main server, the manager may create a virtual button in advance. The virtual button acts as a "push-to-switch" button as shown in fig. 2. When the active/standby mode is required to be switched, an administrator can access the Web service provided by the active server through the user terminal, and a one-button switching button as shown in fig. 2 can be presented on a display interface of a browser of the user terminal. The user may click the virtual button of "one-click switch" on the display interface of the user terminal, thereby generating a primary-standby switch instruction, and then the user terminal sends the primary-standby switch instruction to the primary server, so that the primary server responds to the primary-standby switch instruction, thereby executing the corresponding operations of step S110 and step S120.
In the embodiment, the virtual button is convenient for a user to perform operation of switching the active mode and the standby mode, so that the user experience is improved.
In this embodiment, before step S110, the method may further include:
and when the main and standby switching instruction is acquired, sending a starting instruction to the standby server to trigger the Web system of the standby server to start starting.
It is understood that in the primary and standby systems, when operating in the primary mode, the standby server is in a standby state, and the Web system of the standby server is not started. When the main server receives the main-standby switching instruction, a starting instruction is sent to the standby server. After receiving the start instruction, the standby server automatically triggers the Web system to start starting, which is not described herein.
As an alternative embodiment, after step S110, and before step S120, the method may further include:
a first Web service based on HTTP protocol is provided to a user terminal for displaying page information indicating that a mode switch is being performed on the user terminal.
Understandably, during the mode switching, the main server may provide the first Web service in order to facilitate the user's visual understanding that the mode switching is currently being performed. During the mode switching, when the user transmits a request for performing a Web service to the primary and secondary systems, feedback is performed by the primary server at this time. That is, the main server may return, based on the first Web service, a prompt message indicating that mode switching is being performed to the user. The prompt information can be flexibly set according to actual conditions, so that a user can conveniently know whether the mode switching is completed or not. Illustratively, the hint information may be "hint" as shown in FIG. 2: is being switched.
When the mode switching is completed, a request for providing the Web service may be directly transmitted from the backup server in response to the user terminal. Or the user terminal initiates the request again, and the standby server responds after receiving the request to provide the Web service.
As an alternative embodiment, before step S120, the method may further include:
comparing a first time stamp with a second time stamp, wherein the first time stamp is a time stamp when the main and standby switching instructions are acquired, and the second time stamp is a time stamp when the Web system acquired from the standby server is started;
and when the second time stamp is after the first time stamp, determining that the Web system of the standby server completes the current startup.
Understandably, after the main server obtains the working state of the Web system of the standby server, when analyzing the working state, the main server needs to ensure that the starting time in the working state has the following meaning: the Web system of the backup server is started after the primary server acquires the primary-backup switching instruction, and is not started before the primary server acquires the primary-backup switching instruction.
If the starting time indicates: the Web system of the backup server is started before the primary server obtains the primary-backup switching instruction, which means that the designated file of the backup server records the time stamp of the last start of the Web system, and the Web system may not be started in fact during the primary-backup switching.
When the start-up time indicates: the Web system of the standby server is started after the main server acquires the main-standby switching instruction, which means that the Web system is actually started during the main-standby switching period, and at this time, the address for providing the Web service can be switched from the address of the main server to the address of the standby server.
For ease of understanding, the implementation flow of the method will be illustrated below in conjunction with fig. 2:
assume that in the primary/backup system 20, the access address of the primary server 30 is A1 (Https:// 1.1.1.1), and the access address of the backup server 40 is B1 (Https:// 2.2.2.2).
The administrator adds a Web service (i.e., a first Web service) based on HTTP protocol to the main server 30 in advance, and the access address of the service is A2 (HTTP:// 1.1.1/webming). During a mode switch, when the address of the service is accessed, an HTTP static page may be returned to alert that a reminder in the static page is being switched, illustratively as shown in fig. 2.
In addition, the administrator adds a Web service based on HTTP protocol (i.e., a second Web service) to the backup server 40 in advance, where the access address of the service is assumed to be B2 (HTTP:// 2.2.2.2/checkHealth), and the B2 address of the Web service may be used to obtain a timestamp (hereinafter referred to as a timestamp T2) when the Web system of the backup server 40 completes startup. The time stamp is generated after the Web system of the backup server 40 completes the startup, and is stored in a designated file of the backup server 40. That is, the Web service provided by the backup server 40 can read the content in the specified file and return the time stamp.
The addresses A1, A2, B1, and B2 are exemplary addresses, and may be different from the addresses of A1, A2, B1, and B2 in practical applications. That is, the addresses of the main/standby server and the Web service providing server may be flexibly set according to the actual situation, and are not particularly limited herein.
When the primary server 30 receives the primary/secondary switch command, the time is recorded as T1 (i.e. the first timestamp). In the page of the A2 address, the operation state of the Web system in the backup server 40 needs to be acquired through the B2 address. The B2 address cannot be queried directly through Ajax due to browser homology policies. In this embodiment, the query is performed by creating a Script tag to obtain the contents in the B2 address. The specific method is as follows:
and presetting a function in the page of A2 through the JavaScript program, then circularly creating a Script tag through the JavaScript program, and setting the Src attribute of the Script tag as the B2 address. Then, the Script tag is loaded into the Web page, the Script tag can automatically acquire the resource in the Src attribute (including the starting time stamp T2 of the Web system, namely, the second time stamp) after being loaded, and the acquired resource is operated as JavaScript code, and the functions are called when the code is operated. The start-up timestamp T2 of the Web system of the backup server 40 can be obtained when the function is running.
In this embodiment, the preset function may also be used to compare the time sequence relationship between T2 and T1, and the implementation manner may be:
if T2 is later than T1, the standby server 40 is started after receiving the switching instruction, and then the standby server 40 automatically jumps to the B1 address of the standby server 40 through JavaScript. After the primary-backup switching is completed, the backup server 40 may delete the timestamp T2 stored in the specified file. During the operation of the Web system of the standby server, if a mode switching instruction is received, the identity of the standby server 40 is replaced with the identity of the main server 30 described above, so as to execute steps S110 to S120 until the mode switching is completed.
If T1 does not exist, this indicates that the backup server 40 has not been started. If T2 is earlier than T1, it indicates that the backup server 40 is the timestamp generated when the previous active-backup switch was performed, and it cannot indicate that the backup server 40 has been started in the current active-backup switch.
Based on the design, the problem of limitation of the browser homology strategy can be solved by creating the Script label; by adding HTTP protocol services to the main server 30 and the backup server 40, respectively, the problem of security restriction of the HTTPs protocol can be solved, so that the Web system start-up state of the backup server 40 can be obtained from the page provided by the main server 30.
