In this tutorial, we are going to provide you with step by step instructions on how to install PHP 7 on an Ubuntu 16.04 VPS and on a CentOS 7 VPS<\/strong>. PHP 7 is the latest version of the PHP processing engine and it is faster than any other previous version of PHP. Also, PHP 7 consumes less memory.
\n<\/p>\n

Install PHP 7 on Ubuntu<\/h2>\n

Make sure your server OS packages are fully up to date by running the following commands:<\/p>\n

sudo apt-get update \r\nsudo apt-get upgrade<\/pre>\n
Install PHP and commonly used PHP packages:<\/p>\n
sudo apt-get install php7.0-cli php7.0-common php7.0-json php7.0-readline php7.0-xml php7.0-mysql php7.0-mcrypt php7.0-gd<\/pre>\n
To make sure that PHP 7 is installed on your server, run the following command:<\/p>\n
sudo php -v<\/pre>\n
You should get an output like this:<\/p>\n
PHP 7.0.13-0ubuntu0.16.04.1 (cli) ( NTS )\r\nCopyright (c) 1997-2016 The PHP Group\r\nZend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies\r\nwith Zend OPcache v7.0.13-0ubuntu0.16.04.1, Copyright (c) 1999-2016, by Zend Technologies<\/pre>\n
If you’d like to install additional PHP 7 modules, like OPCache for example, you can use the command below:<\/p>\n
sudo apt-get install php7.0-opcache<\/pre>\n
In order to search for available PHP 7 modules, run:<\/p>\n
sudo apt-cache search php7<\/pre>\n
To see which files are used by PHP in CLI mode, run:<\/p>\n
# php --ini\r\nConfiguration File (php.ini) Path: \/etc\/php\/7.0\/cli\r\nLoaded Configuration File:         \/etc\/php\/7.0\/cli\/php.ini\r\nScan for additional .ini files in: \/etc\/php\/7.0\/cli\/conf.d\r\nAdditional .ini files parsed:      \/etc\/php\/7.0\/cli\/conf.d\/10-mysqlnd.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/10-opcache.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/10-pdo.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/15-xml.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-calendar.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-ctype.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-dom.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-exif.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-fileinfo.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-ftp.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-gd.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-gettext.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-iconv.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-json.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-mcrypt.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-mysqli.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-pdo_mysql.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-phar.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-posix.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-readline.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-shmop.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-simplexml.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-sockets.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-sysvmsg.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-sysvsem.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-sysvshm.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-tokenizer.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-wddx.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-xmlreader.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-xmlwriter.ini,\r\n\/etc\/php\/7.0\/cli\/conf.d\/20-xsl.ini<\/pre>\n
If you only want to locate your php.ini configuration file, use:<\/p>\n
# php -i | grep -i php.ini\r\nConfiguration File (php.ini) Path => \/etc\/php\/7.0\/cli\r\nLoaded Configuration File => \/etc\/php\/7.0\/cli\/php.ini<\/pre>\n
The PHP Opcache extension can boost PHP performance by a large amount, so edit the PHP configuration file:<\/p>\n
vi \/etc\/php\/7.0\/cli<\/pre>\n
Add the following lines in the ‘[opcache]’ section:<\/p>\n
opcache.enable=1;\r\nopcache.memory_consumption=256;\r\nopcache.max_accelerated_files=20000;\r\nopcache.max_wasted_percentage=10;\r\nopcache.revalidate_freq=360;\r\nopcache.fast_shutdown=0;\r\nopcache.enable_cli=0;\r\nopcache.revalidate_path=0;\r\nopcache.validate_timestamps=0;\r\nopcache.interned_strings_buffer=32;\r\nopcache.fast_shutdown=1;<\/pre>\n
Do not forget to restart the web server for the changes to take effect:<\/p>\n
service apache2 restart<\/pre>\n
Install PHP 7 on CentOS<\/h2>\n
Make sure that all OS packages are up to date:<\/p>\n
yum clean all\r\nyum update<\/pre>\n
Check if there are any installed PHP packages, e.g:<\/p>\n
rpm -qa | grep php<\/pre>\n
php-cli-5.4.16-42.el7.x86_64\r\nphp-pdo-5.4.16-42.el7.x86_64\r\nphp-common-5.4.16-42.el7.x86_64\r\nphp-5.4.16-42.el7.x86_64\r\nphp-mysql-5.4.16-42.el7.x86_64<\/pre>\n
Remove PHP 5.4 packages prior installing PHP 7:<\/p>\n
yum remove php-cli php-pdo php-common php php-mysql<\/pre>\n
Add the required repositories:<\/p>\n
cd \/opt\r\nwget https:\/\/dl.fedoraproject.org\/pub\/epel\/epel-release-latest-7.noarch.rpm\r\nwget https:\/\/mirror.webtatic.com\/yum\/el7\/webtatic-release.rpm\r\nrpm -Uvh epel-release-latest-7.noarch.rpm\r\nrpm -Uvh webtatic-release.rpm<\/pre>\n
Install PHP 7 and PHP 7 packages:<\/p>\n
yum install php70w  php70w-cli php70w-mysql php70w-pdo php70w-common<\/pre>\n
To search for available PHP7 modules, run:<\/p>\n
yum search php70w<\/pre>\n
You may install additional PHP extensions, like mycrypt, mbstring, OPCache etc.:<\/p>\n
yum install php70w-opcache php70w-mcrypt php70w-mbstring<\/pre>\n
Check the PHP 7 version installed on your server:<\/p>\n
#php -v\r\nPHP 7.0.15 (cli) (built: Jan 19 2017 21:35:05) ( NTS )\r\nCopyright (c) 1997-2017 The PHP Group\r\nZend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies\r\n    with Zend OPcache v7.0.15, Copyright (c) 1999-2017, by Zend Technologies<\/pre>\n
To optimize PHP 7, locate the PHP configuration file and edit it:<\/p>\n
#php -i | grep -i php.ini\r\nConfiguration File (php.ini) Path => \/etc\r\nLoaded Configuration File => \/etc\/php.ini<\/pre>\n
vi \/etc\/php.ini<\/pre>\n
Add the following lines:<\/p>\n
max_execution_time: 600\r\nmax_input_time: 600\r\nmax_input_vars: 5000\r\nupload_max_filesize: 64M<\/pre>\n
Also, enable OPCache and configure it by adding the same settings in the ‘[opcache]’ section as on the Ubuntu 16.04 VPS.
\nRestart the Apache web server for the changes to take effect:<\/p>\n
systemctl restart httpd<\/pre>\n
Of course, you don’t have to do any of this if you use one of our Software Installation services<\/a>, in which case you can simply ask our expert Linux admins to install PHP 7<\/strong> for you. They are available 24×7 and will take care of your request immediately.<\/p>\n
