PHP 7 was officially launched, if you want to install PHP 7 to experience the speed of it, so I wrote this article guide you to upgrade to PHP 7 for CentOS and Ubuntu operating system and configuration for Apache web server and nginx.

Note that in PHP 7 has many functions have been removed so that if your codes were so old, when upgraded to php7, your website can fail to run, hence you should consider before upgrading it. If the CMS like WordPress, Magento then it is not worry, for WordPress, it should be version 4.3 and Magento is 1.9.2 or higher.

Install PHP 7 on CentOS

CentOS 6.x:

Code:
rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm
yum install yum-plugin-replace
yum replace php-common --replace-with=php70w-common
yum install php70w php70w-opcache php70w-mysql
CentOS 7.x:

Code:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yum install yum-plugin-replace
yum replace php-common --replace-with=php70w-common
yum install php70w php70w-opcache php70w-mysql
After that, check with php-v, if the output is:

PHP 7.0.0 (cli) (built: Jul 2 2015 18:38:21) ( NTS )

Install PHP 7 on Ubuntu

Code:
sudo add-apt-repository ppa:ondrej/php-7.0
sudo apt-get update
If you are using Apache:

sudo apt-get install php7.0
sudo apt-get install php7.0-mysql
If you are using NGINX

Code:

Type php-v to check php version and if it is showing these

Apply for both CentOS and Ubuntu, when Upgrading to PHP 7, if you use NGINX then you need to edit NGINX config file then your websites run, see path location

        fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
