PHP - Script programming language, which is installed by default along with the other standard components of the CentOS 7 operating system. However, updates for this platform are quite rare, so users are forced to work with the old PHP version 5. New PHP 7 assembly will be available only after independent download Suitable repository and further installation of all libraries. As part of today's article, we will try to describe this process as much as possible.
Install PHP 7 in CentOS 7
As the preferential majority of software in CentOS, PHP 7 is installed by entering the corresponding commands in the classical console. The user does not require knowledge of the principles of all algorithms, since it will only be necessary to enter the specified lines in the Terminal. We broke the entire procedure for steps to simplify the task for inexperienced users. Let's start with the first action.Step 1: Adding Required Repository
All PHP 7 components are stored in two storage facilities, which are missing in the CENTOS 7 operating system. The user needs to add them yourself, making sure the availability of active Internet connection.
We want to draw the attention of those users who installed on their PHPMYAdmin. During this procedure, the repositories under consideration below are also added, so you can skip this step.

When requests for confirmation of adding new files, always agree to this, choosing an answer version Y. In addition, we advise you to read the text displayed in the console to the console: sometimes it indicates the occurrence of certain errors. Timely detection and correction will help avoid problems in the future.
Step 2: Activation PHP 7
The creators of the REMI repository argue that it is necessary to add packets based on RPM to the system. This includes the scripted PHP programming language. After completing the first step in CentOS 7, several PHP versions should be available, therefore, it will be necessary to switch to the latest:
- Browse the list of available Remi repository via the standard LS command by entering Ls /etc/yum.repos.d/remi*. With the rest of the properties of the utility used, we propose to get acquainted in a separate material further.

Step 3: Install PHP 7
Adding and activating all components is successfully completed, it remains only to compile directly the PHP 7 itself so that you can start working with this programming language. This is done in entering the console of the corresponding commands.
Checking the PHP version used is available at any time by entering the PHP00 -V or PHP00 -R command "phpinfo ();" | Grep "PHP Version", where 00 in both cases is a suitable version of PHP.
This installation procedure has been successfully completed. Note that switching to the new version is a mandatory process. Additionally, you need to restart the used web servers, if any, but this does not concern Apache. For NGINX, enter Sudo SystemCTL Restart PHP-FPM.
