Use the rpm instruction to delete all PHP packets in 3 seconds

Laravel is a concise and elegant PHP Web development framework (PHP Web Framework). It frees you from the noodle-like clutter of code; it helps you build a perfect web APP, and every line of code can be concise and expressive.

When installing all the frameworks and packages, the first thing you must look at is the environment required by the project. You can see that Laravel requires more than 7.2.5 for PHP. Go to the virtual machine to see the version of PHP, you can check the version through php-v.

Click here is not used, PHP has been deleted, this instruction can not be executed, awkward

So Kaka uses the previous rpm-qa | grep php instruction to show you the previous version.

This version is installed with rmp, so it also needs to be uninstalled using rpm. At this time, all the packages of PHP have been deleted.

So how did Kaka be deleted?

Still using rpm-e php70w.... That's really a waste of time. Good time can't be spent on deleting files.

And some packages have dependencies, which must have happened to you when you deleted them.

This error is that the installation package you need to uninstall is being used by other packages, isn't it? Kaka teaches you to use a command to solve these problems. Rpm-e-nodeps rpm-qa | grep php

At this time, you can delete all the installation packages of PHP in about 3 seconds. Is it very nice?

2. Common parameters of rpm instruction

RPM is the abbreviation of RPM Package Manager (RPM package Manager). Although the file format name is marked with the logo of RedHat, its original design concept is open, which now includes OpenLinux, S.u.S.E. And Linux distributions such as Turbo Linux have been adopted, which can be regarded as a recognized industry standard.

The main function of rpm is to install, uninstall and upgrade.

Here are some commonly used rpm parameters for everyone to use.

-e Uninstall rpm package-I install rpm package-u upgrade rpm package-nodeps does not verify package dependencies

These parameters are frequently used by Kaka.
