First, the working principle of the invention
The invention provides a mode of adding a client side to a server side, wherein the server side is deployed in a server using a domestic operating system and is used for managing various application software versions and initiating software online upgrading operation; the client is deployed on various terminals and servers using the domestic operating system and is responsible for upgrading various application software on the equipment.
The domestic operating system based on Linux supports the rpm format installation package generated by the rpmbuild tool, so that the software upgrading method uses the rpm format installation package, and the service end and the client end cooperate to jointly complete the online upgrading management and control work of third-party application software.
The main work flow of the online upgrading of the application software is as follows:
(1) after an application software manufacturer submits a software version description information file and an installation package to a software publisher, the software publisher uploads a software version to a server;
(2) in the software uploading process, the server signs the software installation package and the version information by using a signature algorithm;
(3) after the signature is successful, integrating the signature information, the version information and the software installation package into a new software package and storing the new software package into a software version library;

(12) and starting the software in the new process according to the operation authority in the operation strategy, and feeding back an upgrading result to the server software.
Second, implementation mode
According to the problems of domestic operating system architecture difference, software data falsified between service interactions, difficult software upgrading and restarting and the like faced by software online upgrading management and control, detailed description is carried out according to software platform adaptation, software signature verification and software upgrading and restarting as follows:
1. software platform adaptation
There are differences in system architectures used by homemade operating systems installed on computers of different hardware platforms, for example: i386, amd64, ia64, mips64el and the like, and the application software installed on the software needs to be adapted to the architecture to normally run. Therefore, when software is upgraded on line, the upgrade success can be achieved by identifying the type of the national operating system architecture and analyzing the type of the software version. In order to solve the problem of automatic identification of software versions, the patent proposes the following idea.
(1) Multi-platform software version warehousing
Before releasing a new version of software, an application software manufacturer requires to make a software installation package suitable for each system architecture, and fills a software version description information document according to format requirements, wherein the contents comprise: package name, software version number, software type, applicable platform (e.g., ia64, i386, i686, amd64, mips64el, etc.), manufacturer, release time, software size, description information. The software version description information document is an excel file with a fixed format, and is provided for various manufacturers by an application software manager to fill in when a new software version is released so as to standardize the software version description. And after completing filling by each manufacturer according to the format requirement in the file, submitting the excel file and the corresponding software installation package to an application software manager for issuing at a server. The Excel file content solidification format is as follows:
table 1 software version illustrates excel file content format
According to the actual installation verification of the multi-platform software, a software installation package manufactured on one platform can be compatible with the situations of a plurality of platforms, such as: the rpm install package fabricated on the i386 system architecture computer can run on the homemade operating systems of the i386, ia64, amd64 system architectures. Therefore, after the software installation package is manufactured on one platform, if the software installation package can normally run on a plurality of platforms, multi-platform selection can be performed on the applicable platform in the software version description excel file.
And after receiving the software installation package and the software version description excel file submitted by each manufacturer, the application software manager submits the software installation package and the software version description excel file to a software version library of the server.
(2) Automatic analysis of software upgrade versions
In the process that the server side initiates the software online upgrade to the client side, the client side obtains the system architecture and the software information installed in the system and feeds the software information back to the server side for version analysis, and the software upgrade version corresponding to the software upgrade version is found out.
The client software adopts an API interface provided by a cross-platform JAVA design language to acquire system architecture information, so that a platform compatibility effect is achieved, and the implementation method comprises the following steps:
Properties p＝System.getProperties()；
String osArch＝p.getProperty("os.arch")；
the method for operating the 'rpm-qai' command on the domestic operating system by using the API provided by the JAVA design language can completely acquire the software information installed in the system, and comprises the following steps:
the method comprises the steps that after a client side collects system architecture and software version information, the system architecture and the software version information are fed back to a server side, the server side extracts a software name (sName), a version number (sVersion) and a system architecture (sArch), then the software name (dName), the version number (sVersion) and the system architecture (sArch) are completely matched with a software name (dName) and a version number (dVersion) in a version library, the system architecture and a software application platform (dArch) in the version library are subjected to attribution matching, and after the system architecture and the software application platform (dArch) are successfully matched, the software version information is extracted from the version library and used for software upgrading. The matching rules are described generally as:
sName＝＝dName&&sVersion＝＝dVersion&&(sArch In dArch)。
2. software signature verification label
In order to prevent the software installation package and the version information from being tampered in the storage and transmission processes, reduce the interaction times among services and improve the software upgrading efficiency and safety, the software installation package and the version information are integrated and signed into a file before being put in storage, and the storage and transmission in the future are integrated files. And when the software is upgraded, checking the label of the integrated file, taking out the software installation package after the label passes the check, and upgrading the software.
Before the software version information is put in storage, the server signs the software version information and the software installation package by using a signature algorithm (which can be determined and replaced according to actual use requirements, and the invention is not specifically described), and fuses a signature value, the software version information and the software installation package into a new software installation package according to rules, thereby facilitating service use and reducing interaction steps among services; when the software is upgraded, the client extracts the signature value and brings the signature value into a signature verification algorithm to verify the signature of the software version information and the software installation package data. And extracting complete software installation package and software version information after the verification of the signature. The content field of the new software package after the software signature integration is shown in fig. 1, and includes the following contents:
1) signature length: 4 bytes, storing signature value byte length;
2) signature value: the method comprises the steps of obtaining version information length, version information, software length and a signature value of software content;
3) version information length: 4 bytes, storing the length of the version description information byte;
4) version information: JSON format version description information;
5) software length: 4 bytes, software content length field;
6) software content: software installation package data.
The specific steps of the signature and signature verification process of the integrated software package are described as follows:
(1) assembling attributes such as a software package name, a software type, an applicable platform and the like in the software version information by sequentially using a JSON format to generate a byte array (sv);
(2) calculating the length (svl) of the JSON format software version information byte array, and storing by using 4 byte space;
(3) calculating the length (sil) of the software installation package data (si), and storing the length (sil) in a 4-byte space;
(4) assembling the svl, the sv, the sil and the si into a new byte array (namely svl + sv + sil + si) in an overlapping mode in sequence, calculating a signature value (v) of the new array by using a signature algorithm, and storing the signature value v by using a 4-byte space (vl);
(5) finally, the byte arrays of vl, v, svl, sv, sil and si are sequentially stored into a new file in an rpm format and expressed as a signed software package;
(6) before software upgrading, the signed software package extracts contents according to the sequence of vl, v, svl, sv, sil and si;
(7) and substituting v into a signature checking algorithm, checking the svl + sv + sil + si content, extracting the si content to generate a new rpm format installation package, and extracting sv to analyze the software version information according to the JSON format.
3. Software upgrade restart
After the version information and the software installation package are extracted, the software operation stopping, software upgrading and software restarting processes are executed according to the flow, and the difficulties and the solving means in the three processes are respectively described in detail below.
(1) Software shutdown
Since the stop script is not necessary for every software, the stop script path in the software version information may not be configured. If a software stop script path (stopsoft path) is configured, the running software to be upgraded can be stopped by directly running the stop script path through the JAVA language, and the implementation method is as follows:
String stopSoft＝"sh"+stopSoftPath；
Process p＝Runtime.getRuntime().exec(stopSoft)；
if the software stop script path is not configured, a combined command needs to be written to stop the running software to be upgraded (softName). In order to make the stop command compatible with various domestic operating systems and efficiently and accurately stop the software, a ps command is designed to acquire a process ID number of a specified software name and is used as a combined command of kill command parameters to end the process, and the stop work can be completed by calling the command through a JAVA language, and the realization method is as follows:
String stopSoft＝"ps–ef|grep"+softName+"|awk'{print$2}'|xargs kill-9"；
Process p＝Runtime.getRuntime().exec(stopSoft)；
(2) software upgrade
And extracting a new software installation package (cache path softPath), and upgrading the software installation package by calling an rpm command through a JAVA language. Because some dependencies exist in some software installation packages during upgrading, which may result in unsuccessful software upgrading, it is necessary to cooperate with multiple parameters in the rpm command to ignore the software dependencies and enforce the upgrading
String rpmCmd＝"rpm-U--force--nodeps"+softPath；
Process p＝Runtime.getRuntime().exec(rpmCmd)；
(3) Software restart
After the software is successfully upgraded, the upgraded software (softName) needs to be started in a new process mode according to the operation authority (isRootRun) and the startup script path (startSoftPath) configured in the software version information, and finally, the software upgrading and restarting results are fed back to the server.
In the process of restarting the software, if the operation authority is configured to require the ROOT user authority to operate, the ROOT authority is appointed when the program is started, otherwise, the current login user authority is used for starting the software. In order to prevent the software from being hosted in the client side of the present invention after being started, a genome-terminal command is required to be used to newly build a terminal window, and a user authority is specified to execute a software start script, and the implementation method is as follows:
