Install PHP 7 on Debian/Ubuntu

These are a set of bash scripts for building and running PHP 7 (CLI and FPM) on Debian based Linux distributions:

build.sh installs the necessary build dependencies and the latest development version of PHP with CLI and FPM server APIs (SAPI) from the PHP-7.0.0 branch of https://github.com/php/php-src
install.sh sets up PHP-FPM by moving configuration files into their correct locations in /usr/local/php7 and enables the php7-fpm service and adds it to the startup sequence.

Please note that these are very simple scripts that don't implement error checking or process validation.

Usage

$ git clone https://github.com/kasparsd/php-7-debian.git
$ cd php-7-debian
$ ./build.sh
$ ./install.sh

The PHP-FPM can be operated using the php7-fpm init script:

Usage: /etc/init.d/php7-fpm {start|stop|status|restart|reload|force-reload}

while the FPM socket is available at

127.0.0.1:9007

and PHP CLI:

$ /usr/local/php7/bin/php -v
PHP 7.0.0-dev (cli) (built: Apr 23 2015 18:14:01)

Configuration files

All PHP configuration files are stored under /usr/local/php7:

/usr/local/php7/lib/php.ini
/usr/local/php7/etc/php-fpm.conf
/usr/local/php7/etc/php-fpm.d/www.conf
/usr/local/php7/etc/conf.d/modules.ini

while the Debian init script is added to:

/etc/init.d/php7-fpm

Extensions

Note that most of the third-party PHP extensions are not yet compatible with PHP 7 and GoPHP7-ext (also on GitHub) is a project to help do that. Here is a list of PHP modules that are enabled by default in this build:

$ /usr/local/php7/bin/php -m

Installing Memcached Extension

Memcached extension for PHP already supports PHP 7. First you install the dependencies:

$ sudo apt-get install libmemcached-dev libmemcached11

and then build and install the extension:

$ git clone https://github.com/php-memcached-dev/php-memcached
$ cd php-memcached
$ git checkout -b php7 origin/php7

$ /usr/local/php7/bin/phpize
$ ./configure --with-php-config=/usr/local/php7/bin/php-config
$ make
$ sudo make install

and then append extension=memcached.so to /usr/local/php7/etc/conf.d/modules.ini:

# Zend OPcache
zend_extension=opcache.so

# Memcached
extension=memcached.so
