Detailed explanation of the methods of upgrading the version of software package under linux

In the Linux environment, you want to see if a certain software (package) is installed.

Installed in rpm package mode, use rpm-qa | grep "software or package name".

Installed in yum mode, yum list installed | grep "name of the software or package".

Upgrade the package version.

We often encounter situations where we rely on other versions of the package (usually a newer version), when we need to upgrade the package.

1. Install the new package after uninstalling.

First of all, you should check whether you have installed the software according to the way mentioned at the beginning of the article to see if the package is installed. if not, find the path and use the wget command to download the package and install it directly.

If installed, the version of the software you installed will be displayed. You can simply copy the package name when you write the uninstall command later.

Use

Rpm-e software.rpm (uninstall)

Rpm-e-nodeps package name (force uninstall)

Rpm-U software.rpm (installation in upgraded form)

After uninstalling, you can install it using the rpm-ivh package name.
