1. Use rpm command to delete all PHP packages in 3 seconds
When installing all frameworks and packages, the first thing you must look at is the environment you need for your project. You can see that Larave requires PHP version 7.2.5 or above.
Go to the virtual machine to see the PHP version, you can check the version with php -v.
Click here is not used, PHP has been deleted by click, this command can not be executed, embarrassing...
So, click, click,| The grep php command displays information to show you the version before click
This version is installed by rmp, so it also needs to be uninstalled by rpm. All PHP packages have been removed.
How did that click get deleted?
Still using rpm -e php70w... That would be a waste of time. Good time could not be spent deleting files.
And some packages have dependencies, which you must have encountered when deleting them.
This error means that the installation package you need to uninstall is being used by another package.
Kaka teaches you to use a command to solve these problems. rpm -e --nodeps rpm -qa | grep php
At this time, it takes about 3 seconds to remove all PHP installation packages. Is it very nice?
II. Common parameters of rpm command
The main function of rpm is to install, uninstall and upgrade.
Here are a few common rpm parameters for everyone to use.
-e uninstall rpm package-i install rpm package-u upgrade rpm package--nodeps do not verify package dependencies
These parameters are frequently used by Kaka.
3, yum install PHP 7.2
installation source
rpm -Uvh https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
Or you can use this.
yum install epel-release -y
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
Install required extensions
yum -y install php72w php72w-cli php72w-fpm php72w-common php72w-devel php72w-embedded php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml
After the completion of the implementation to see the version number is 7.2 in the browser inside can be normal access, nginx is a click before the installation has been good.
