After that, we use the “reposdir” command to output the repository’s directories and files.

Then, we set a print command of logFile using the “yb” variable to fetch the logfile path of YUM. First, we have a print statement that displays the path of the YUM configuration file. The print statements are given to check the configuration of YUM. We use this line of code in each of our example scripts because YumBase is the root class that contains the methods and objects that are needed to carry out all of the package management operations using YUM. After that, we create the “yb” variable where the yumBase() base class of the “yum” module is deployed. The previous source code is imported with the “yum” module along with the other required modules. YUM is used to examine the YUM configuration in this case. Now, the “yum” Python package must be imported to begin using YUM in programming which is preinstalled in the CentOS operating system. The previous approach is to update the YUM package using the Python script by interacting with CentOS. The output prints the statement which states that “no packages marked for update” because YUM is already updated in CentOS.Įxample 2: Check for the YUM Configuration Using Python in CentOS When we execute this Python file, it starts to update YUM. The script is saved in the file “script.py” here. Then, we use “cmd” to interpret the statement that is assigned to it. We import the “os” module to interact with the CentOS operating system. The Python script is given where YUM is used to update. Here, we update YUM with the Python file to check whether the YUM module is updated within the system or it requires an update. We will learn more about YUM using Python on the CentOS system in this article.Įxample 1: Update the YUM Module Using Python in CentOSĪs we know, YUM is a command-line tool that enables the users to automatically install and download the updated RPM packages after checking for updates. YUM can determine, fetch, and install all available dependents packages automatically as it automatically resolves the dependency while updating, adding, or removing the packages. YUM simplifies the software installations on a CVM instance and makes it simple to download and install the programs which saves time and effort.

YUM is a utility for handling software packages that are used by several well-known operating systems such as Fedora and CentOS.
