Detailed ways

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. 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 obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

To solve the prior art problem, the embodiment of the present application provides a software processing method, device, electronic device, and computer readable storage medium, which are described in detail below.

It should be noted that the execution body of a software processing method provided by the embodiment of the present application may be a software processing device. In practical applications, the software processing device can be run in the terminal device, so that the administrator can use the terminal device to perform software online, which is reasonable.

FIG. 1 is a schematic flowchart of a software processing method according to an embodiment of the present disclosure, where the method includes the following steps:

S101. Obtain a processing instruction for the software.

It should be noted that, in an implementation manner, obtaining the processing instruction of the software may include: obtaining a processing instruction for the software from a preset integrated tool. The preset integrated tool is set in the terminal device, and the integrated tool can provide a human-computer interaction interface. Exemplarily, in the human-computer interaction interface, for each software, icons of various different functions may be respectively set correspondingly, so that the administrator implements the clicked icon on the software by clicking an icon corresponding to a certain software. Corresponding function. For example, the “online” icon corresponds to the software online function, the “rollback” icon corresponds to the software rollback function, the “software uninstall” icon corresponds to the software download function, and so on. Of course, in the human-computer interaction interface, an icon of a different function can be set for all software, and a function corresponding to the clicked icon can be realized by the manager clicking an icon.

In one implementation, the preset integrated tool can be jenkins. Jenkins is an open source software project designed to provide an open, easy-to-use software platform that is a continuous integration tool developed in Java to monitor continuous repetitive work. Specific functions can include: continuous software release/testing of projects, monitoring of external call execution. Jenkins can provide a human-computer interaction interface for obtaining software processing instructions, which the terminal device then obtains from Jenkins. Exemplarily, the human-computer interaction interface provided by Jenkins has icons of various functions, one or more icons for the user to issue processing instructions to the software, such as an "online" button, a "rollback" button, and the like.

In another implementation manner, the software processing method in the embodiment of the present application may be implemented by using a script. The script has a function of realizing a human-computer interaction interface, that is, the software processing device as an execution subject can be a script program. In this way, the management personnel can issue processing instructions for the software through the human-computer interaction interface provided by the software processing device, so that the software processing device obtains the processing instruction. The form of the human-computer interaction interface provided by the software processing device may refer to the human-computer interaction interface provided by the preset integrated tool, and details are not described herein.

Specifically, the processing instruction obtained in S101 carries the target identifier of the target software to be processed. It can be understood that there may be multiple kinds of software to be processed. When obtaining the processing instruction of the software to be processed, it is also necessary to know which software operation the processing instruction is for; therefore, in order to obtain the specific software for which the processing instruction is directed, The target identifier of the target software to be processed is also carried in the processing instruction.

It can be understood that the target identifier has a one-to-one correspondence with the target software. As an example, as shown in Table 1, Table 1 includes the correspondence between the target software and the target identifier. For example, when the processing instruction includes the target identifier A00, because the identifier A00 is the target identifier of the chat software A, it indicates that the pending instruction is made for the chat software A; when the processing instruction includes the target identifier B02, because the identifier B02 is the target identifier of the shopping software B, so that the pending instruction is made for the shopping software B; when the processing instruction includes the target identifier C01, because the identifier C01 is the target identifier of the payment software C, it indicates that the pending The instructions are made for payment software C.

S102, when it is determined that the processing instruction is an online operation instruction, determining a target software package to be updated from the pre-stored software package to be updated, and the target software package to be updated is: the software package to be updated with the target identifier.

It should be noted that after receiving the processing instruction, the terminal device can determine what type of instruction the processing instruction is. When it is determined that the online operation instruction is an online operation instruction, the target software package to be updated is determined from the pre-stored software package to be updated.

It is to be understood that a storage area for storing the software package to be updated is preset in the terminal device, and the software package to be updated in the storage area is a pre-stored software package to be updated, and the software package to be updated may include multiple Software package to be updated.

It should be noted that when the processing instruction is an online operation instruction, the software package to be updated with the target identifier may be obtained according to the target identifier included in the processing instruction in step S101, and the obtained software package to be updated is determined as the target software to be updated. package. Specifically, the software package identified by the software in the software package as the target identifier may be determined as the target software package to be updated.

Exemplarily, the pre-stored software package to be updated includes: the software package X to be updated, the software package Y to be updated, and the software package Z to be updated, and the software identifiers are: A00, B02, and C01; When the target identifier of the package is A00, the software identifier A00 of the software package to be updated is the same as the target identifier A00, so that the software package X to be updated is the target software package to be updated; when the target identifier carried in the processing instruction is B02 Since the software identifier B02 of the software package to be updated Y is the same as the target identifier B02, it is determined that the software package Y to be updated is the target software package to be updated; when the target identifier carried in the processing instruction is C01, the software package Z to be updated The software identifier C01 is the same as the target identifier C01, so it is determined that the software package Z to be updated is the target software package to be updated.

S103. Determine a target version number of the target software package to be updated.

It can be understood that the software package can include the version number of the software. After determining the target software package to be updated, the terminal device can determine whether it is necessary to update the target software package to be updated to the server. The processing idea can first determine the target version number of the target software package to be updated.

In one implementation, the target version number of the target software package to be updated may be determined from the name of the target software package to be updated. Exemplarily, the name of the target package to be updated is: liaotian.V2.0.exe, then it can be determined that the version number of the target to be updated package is V2.0.

In another implementation manner, the terminal device may obtain the target version number in the attribute by viewing the attribute of the target software package to be updated. Exemplarily, the target to be updated software package is the software package X to be updated, and the terminal device can obtain the target version number directly from the attribute of the software package X to be updated: V2.5. The target version number of the target software package to be updated in the embodiment of the present application is only exemplary, and the target version number may also be obtained through other preset information fields of the target software package to be updated, which is not specifically limited in this embodiment of the present application. .

S104. Determine, according to the target version number and the pre-recorded historical version number corresponding to the target identifier, whether the target software meets the update condition, and if yes, execute S105.

It can be understood that the version number of all historically installed software packages of the target software is pre-recorded in the terminal device, and the version numbers of all installed software packages form a historical version number. Since the target software has a target identifier, all historical version numbers of the target software correspond to the target identifier of the target software. Exemplarily, the target software is chat software A, the target identifier is A00, and the historical version numbers corresponding to A00 are: V1.3, V1.5, V1.8, V1.9, V2.0, V2.1 , V2.2, V2.3, V2.4.

In the embodiment of the present application, whether the target software meets the updated condition can be determined according to the target version number and the historical version number of the target software. Specifically, the embodiment of the present application provides a specific implementation manner. Referring to FIG. 2, FIG. 2 is a second schematic flowchart of a software processing method according to an embodiment of the present disclosure, which may include steps: S201, S202, S203, and S204. among them,

S201. Determine a highest historical version number in a historical version number corresponding to the target identifier recorded in advance.

It should be noted that the historical version number is: the version number of the software package corresponding to the target identifier and installed in the server. For example, the version number V1.3 corresponding to the target identifier A00 indicates that the chat software A in the server has installed the software package with the version number V1.3, and the software includes the target identifier A00.

Exemplarily, the historical version number corresponding to the target identifier A00 is pre-recorded in the terminal device: V1.3, V1.5, V1.8, V1.9, V2.0, V2.1, V2.2, V2. 3, V2.4, according to the software naming rules: the V2.x series version is higher than the V1.x series version, so the highest V2.4 in the V2.x series version is the highest historical version number.

It should be noted that the version number of the software will have different naming rules, and the highest version number can be found by naming rules. For example, the software version is: V02.00.01. Assume that the large version number is 02.00 and the 01 is a small version number. When the large version number is the same, the larger version number is the same, the larger the smaller version number is, the higher the version is. The version number of V02.00.03 among the three version numbers V02.00.01, V02.00.02, and V02.00.03 is the highest.

In practical applications, the version number can also be named by time. If it is named by time, the version number closest to the current time is the highest version number. Exemplarily, the historical version number corresponding to the target identifier A00 is pre-recorded in the terminal device: V2016.03.20, V2016.08.01, V2017.02.01; V2016.03.20 indicates the software package for updating the target software on March 20, 2016. ;V2016.08.01 represents the software package for updating the target software on August 1, 2016; V2017.02.01 represents the software package for updating the target software on February 1, 2017; the closest to the current date is: 2017.02.01, Therefore, V2017.02.01 is the highest historical version number. Therefore, the highest version number can be obtained as long as the naming rule is set, and the embodiment of the present application does not specifically limit it.

S202. Determine whether the target version number is higher than the highest historical version number; if yes, execute S203; if no, execute S204.

In the embodiment of the present application, the obtained target version number is compared with the highest historical version number obtained in S201, and it is determined whether the target version number is higher than the highest historical version number. Exemplarily, the highest historical version number of the chat software A is V2.4, and the target version number of the software package to be updated is V2.5. According to the comparison rule of the foregoing software version, the target version number is determined to be higher than the highest historical version number. S203 is executed; the highest historical version number of the chat software A is V2.6, and the target version number of the software package to be updated is V2.5. According to the comparison rule of the foregoing software version, the target version number is determined not to be higher than the highest history. Version number, execute S204.

S203. Determine that the target software meets the update condition.

It can be understood that the highest historical version number of the chat software A is V2.4, and the target version number of the software package to be updated is V2.5, because the target version number is higher than the highest historical version number, indicating the target corresponding to the target version number. The version of the package to be updated is higher than the version of the package that was installed before, so it is determined that the target software meets the updated conditions.

S204. Determine that the target software does not meet the update condition.

It can be understood that the highest historical version number of the chat software A is V2.6, and the target version number of the software package to be updated is V2.5. Because the target version number is not higher than the highest historical version number, it indicates that the target version number corresponds to The target to be updated package is the same as the one installed in history. Therefore, for the target software, the update is the same version of the replacement or even the version of the rewind. It does not have the meaning of the software update, so the target software is not determined. Meet the updated conditions.

Applying the embodiment shown in FIG. 2 of the present application, by determining that the target version number is higher than the historical version number, it is determined that the target software meets the update condition; otherwise, the update condition is not met. It can be simple and quick to determine whether the target to be updated software package can be used to update the target software, and can prevent personnel from mistakenly using the lower version of the software package to be updated to update the operation error caused by the target software.

S105: Send the target to be updated software package to the automatic operation and maintenance component, so that after receiving the target to be updated software, the automated operation and maintenance component determines at least one target server of the installed target software according to the pre-stated installation relationship between the software and the server. And updating the target software in the at least one target server when detecting that the predetermined update condition is met.

In the embodiment of the present application, in the case that the target software meets the update condition, the terminal device sends the target software package to be updated to the automatic operation and maintenance component. Specifically, the automated operation and maintenance component can be any one of a saltstack component, an ansible component, or a puppet component.

It should be noted that the automated operation and maintenance component can be a general term for an automated operation and maintenance tool that can connect and control multiple servers. It has the characteristics of easy deployment, operation in a few minutes, scalability, and easy Manage tens of thousands of servers, fast enough, and seconds of communication between servers.

It can be understood that the specific information of the server and the software installed therein is pre-stated in the automatic operation and maintenance component, so according to the information, the target software can be installed in those servers. Exemplarily, the target software is chat software A, and the target server is obtained according to the information: server 1 to server 10. The number of the target servers in the embodiments of the present application is merely exemplary and does not specifically limit the embodiments of the present application.

In addition, it can be understood that software updates need to consume not only the broadband resources between the automated operation and maintenance components and the server, but also their own hardware and software resources. Based on this, an update condition can be set, and when it is detected that the predetermined update condition is met, the target software in the at least one target server is updated, otherwise it is not updated.

In an embodiment of the present application, the predetermined update condition may be that a data transmission rate between the automated operation and maintenance component and the at least one target server reaches a predetermined rate threshold. It can be understood that when the data transmission rate between the automatic operation and maintenance component and any one of the target servers is too low, the target software to be updated and the transmission of the update command are affected, so the update effect is affected. Specifically, the rate threshold may be set. If the set rate threshold is 1 M/s, when the real-time data transmission rate is less than 1 M/s, the update operation is not performed to avoid the transmission failure due to the transmission rate being too low, thereby causing the transmission to fail. This software update failed.

In another implementation manner of the present application, when the load of a certain target server is too large, a process may occur during the processing of the update, thereby causing an interruption of the update operation. To avoid this situation, it may be set. The current running load of at least one target server is determined to be lower than a predetermined load value. Specifically, the load value may be set to 60%. When the load value of the server is greater than 60%, the update action is not performed; otherwise, the update action is performed; to further improve the success rate of the target software update.

It should be noted that the saltstack component adopts a brand-new infrastructure management method, which runs faster and generally runs in a few minutes. It has good scalability and is easy to manage tens of thousands of servers; and it is fast enough to achieve Second level communication with the server. Ansible is an emerging automation operation and maintenance component. Based on Python development, it combines the advantages of many operation and maintenance tools, and can realize functions such as batch system configuration, batch program deployment, and batch operation instructions. Puppet is a centralized configuration management system for Linux, Unix, and Windows platforms. It uses its own puppet description language to manage configuration files, software packages, system services, etc. Puppet uses a C/S star structure and can be combined with one or Several servers interact.

From the characteristics of the above-mentioned automated operation and maintenance components, the saltstack component, the ansible component or the puppet component can be used as an automated operation and maintenance component. They can communicate with one server at the same time, or communicate with multiple servers at the same time. The dimension component can update the target software to multiple servers at the same time to achieve the purpose of concurrent processing. Exemplarily, if there are 20 servers communicating with the automated operation and maintenance component, the automated operation and maintenance component can send the received target to be updated package to the 20 servers to perform target software on the 20 servers. Update.
