[0007] 2) Determine the dependency packages required for software installation and install the dependency packages required for the software;

[0008] 3) Determine the installation type of the dependent package;

[0009] Record the dependency packages that need to be installed online and download the recorded dependency packages;

[0010] 4) Package the downloaded dependency packages into the installation package, package all dependency packages into the software installation package, and package all downloaded component installation packages into one installation file to achieve offline installation of the software package.

[0011] Furthermore, in the above-mentioned method for making a software offline installation package based on the Linux system, in step 1), the simulation target production installation environment is:

[0012] In the virtual machine environment, install the CentOS7.6 minimal Linux system to ensure its public network access environment.

[0013] Furthermore, in the above-mentioned method for making an offline software installation package based on the Linux system, in step 2), the software is installed and dependent packages that need to be installed online are recorded;

[0014] When installing the software, the system searches for dependent packages based on the dependent container environment and database. If the dependent package does not exist locally, it is automatically installed online.

[0015] Furthermore, in the above-mentioned method for making a software offline installation package based on the Linux system, the container environment is a tomcat environment.

[0018] S300: Obtain the installation status of the dependent package according to the log information. If the log contains the words "http" or "https" network address when the dependent package is installed, it means that the dependent package needs to be installed online, and then record the name of the dependent package;

[0019] S310: Download the recorded dependency packages, and use the yuminstall-y{dependency package name}--download-only--download-dir. / packtmp command to download the dependency packages to a temporary path respectively.

[0020] Furthermore, in the above-mentioned method for making a software offline installation package based on the Linux system, in step 4), the downloaded dependency package is packaged into the installation package;

[0021] Use the tar command to compress the downloaded dependency packages into an independent file. Before installing the software, use the yum -y localinstall {dependency package path} command to install the dependency packages offline.

[0032] 1) Prepare the target installation environment and simulate the target production installation environment;

[0033] In the virtual machine environment, install the CentOS7.6 minimal Linux system to ensure its public network access environment;

[0034] 2) Determine the dependency packages required for software installation and install the dependency packages required for the software;

[0035] When installing the software, the system searches for dependent packages based on the dependent container environment and database. If the dependent package does not exist locally, it is automatically installed online. The container environment is Tomcat and the database is MySQL.

[0036] 3) Determine the installation type of the dependent package;

[0037] Record the dependency packages that need to be installed online and download the recorded dependency packages;

[0038] S300: Obtain the installation status of the dependent package according to the log information. If the log contains the words "http" or "https" network address when the dependent package is installed, it means that the dependent package needs to be installed online, and then record the name of the dependent package;

[0039] S310: Download the recorded dependency packages, and use the yuminstall-y{dependency package name}--download-only--download-dir. / packtmp command to download the dependency packages to a temporary path respectively;

[0040] 4) Package the downloaded dependency packages into the installation package, package all dependency packages into the software installation package, and package all downloaded component installation packages into one installation file to achieve offline installation of the software package;

[0041] Use the tar command to compress the downloaded dependency packages into an independent file. Before installing the software, use the yum -y localinstall {dependency package path} command to install the dependency packages offline.

[0042] Example:

[0043] Step S100, installing the CentOS7.6 minimized system in the virtual machine environment;

[0044] Step S200, execute the yum command to install dependent packages such as jdk, mysql-server, tomcat, nginx, etc.;

[0045] Step S300: If the log shows that a dependency has started downloading, execute:

[0046] Step S310, execute the command yuminstall-y --download-only

[0047] --download-dir. / packtmp{dependency package name}, download the installation package of the dependency package to the / packtmp path;

[0048] Repeat steps S300 and S310 until all dependent packages are installed;

[0049] Step S400, pack all dependent packages under the / packtmp path, command: tar cvfz deps.tar.gz / packtmp / *; install all dependent packages in the new CentOS7.6 minimized system, yum localinstall-y / packtmp / *.

[0050] In summary, the present invention realizes offline installation of the entire software package based on offline installation of the RPM software package; pre-downloads the dependent installation package corresponding to the system environment, accurately matches the target environment, reduces compatibility issues, meets the needs of offline installation, integrates the installation package into a single file, and simplifies the installation process.

[0051] Download and package all the dependencies required by the software together, and generate an independent installation file. The installation does not rely on the public network environment, saving time and effort.

[0052] Only one online environment preparation and software installation process is required to create an offline installation package, which simplifies the installation process and saves operation and maintenance workload.
