Introductory

Debian 9 (Stretch) is official in the trunk a PHP 7.0.x version is availablewhich is already over time went by a bitand you will no longer receive updates. Therefore, we may need newer versions if we run live websites, but we can even expand our test environment. We’ve dealt with compiling PHP from source before Debian to 8 and Debian to 9 also, now the deb.sury.org using our external repository, we will conveniently install several PHP versions, including PHP-FPM can be used side by side on Debian 9 (Stretch), Debian 8 (Jessie) or even Debian 10 (Buster) with the server API.

The deb.sury.org repository is unofficial Debian package store, but its maintainer (Ondřej Surý) has been building PHP packages into Debian 's official repository since PHP 5, so we can safely use the latest versions of PHP and other add - ons on his Debian or Ubuntu server. An additional benefit of using the repo is that newer packages are added to our system from time to time APT it is easy to update with the package manager.

 

 

basic Conditions

You need at least one to make this recipe Apache web server to retrieve php output from the server (PHP will be installed in this tutorial, of course).

If we start with a minimal server, such as one of the following:

then install Apache (as root) using the following command:

apt-get -y install apache2

Or we can start one With the LAMP system which also include Apache in addition to Apache MySQL / MariaDB database server and basic PHP:

You can install the PHP versions shown below on the perfect servers, but in this case you need to configure them in the ISPConfig control panel to use them for our web pages. You can read about it here: How to configure custom PHP versions on our ISPConfig server

As the title of the description suggests, I will do this task on the Debian 9 (Stretch) LAMP server, so we will be able to build more on this server later.

 

Deploying the deb.sury.org repository

First, install some required packages:

apt-get install -y apt-transport-https ca-certificates

Az apt-transport-https package allows us to use it in our APT source list HTTPS available libraries. THE ca-certificates and contains a list of trusted certificate authorities that SSL applications can verify the authenticity of SSL connections.

Once you're done, log in to your luggage GPG keys storage directory:

cd /etc/apt/trusted.gpg.d/

Then download the GPG key of sury.org into this directory, named by some name (with the -O switch) so that we can later know whose GPG key it is:

wget https://packages.sury.org/php/apt.gpg -O sury-org-php.gpg

Then open our APT source file for editing:

nano /etc/apt/sources.list

Then add the line corresponding to our main Debian version:

deb https://packages.sury.org/php/ <Debian kódnevünk> main

Where to replace our Debian code name as follows (in lower case):

  • For Debian 8: "Jessie"
  • For Debian 9: "Stretch"
  • For Debian 10: "buster"
  • For Debian 11: "bull's eye"

(Make sure there are spaces before and after the code name.)

Save the file and update our libraries:

apt-get update
apt-get -y upgrade

At the beginning of the update, it announces that some packages will be withheld. For example:

Az alábbi csomagok vissza lesznek tartva:
  libapache2-mod-php7.0 libxml2 linux-image-amd64 php-bz2 php-mbstring php-mysql php-xml php7.0-bz2
  php7.0-cli php7.0-common php7.0-curl php7.0-gd php7.0-imap php7.0-intl php7.0-json php7.0-mbstring
  php7.0-mcrypt php7.0-mysql php7.0-opcache php7.0-pspell php7.0-readline php7.0-recode php7.0-sqlite3
  php7.0-tidy php7.0-xml php7.0-xmlrpc php7.0-zip
This is because the packages for the default PHP version of our system are installed, but the Sury.org package also has packages with the same name. These can be upgraded to newer ones later (if there are newer ones above, e.g. from a branch newer than 7.0), but we can also leave "factory" packages from this PHP branch. Of course, the PHP packages for the appropriate version of Debian are listed here.
If you would like to upgrade any of these withheld packages, please see the following link for implementation:
How to update our hold packages using the APT package manager

As our goal is to add newer versions of PHP7.0, so we are not dealing with 7.0, but we are starting to install newer versions of PHP.

 

 

Install PHP versions

You can install several versions of PHP from the sury.org repository, currently 5.6, 7.0, 7.1, 7.2, 7.3 and 7.4. Suppose these are the ones we need, but we can even assume all of them.

basic Packages

Before installing the different versions of PHP, it is a good idea to install some basic packages that provide the necessary additional features for each version of PHP.

The command includes the installation of several packages, so I display them in separate lines, which can be run copied at once

apt-get -y install \
    mcrypt \
    imagemagick \
    memcached \
    php-apcu \
    php-gettext \
    php-imagick \
    php-memcache \
    php-pear \
    php-yaml

Then you can install different versions of PHP.

PHP 5.6

Although this is an older version, but if you already have it in the new repository and need it, eg. to run an old website, install it with the following command:

apt-get -y install \
    php5.6 \
    php5.6-bcmath \
    php5.6-bz2 \
    php5.6-cgi \
    php5.6-cli \
    php5.6-common \
    php5.6-curl \
    php5.6-fpm \
    php5.6-gd \
    php5.6-imap \
    php5.6-intl \
    php5.6-json \
    php5.6-mbstring \
    php5.6-mcrypt \
    php5.6-mysql \
    php5.6-opcache \
    php5.6-pspell \
    php5.6-recode \
    php5.6-soap \
    php5.6-sqlite3 \
    php5.6-tidy \
    php5.6-xml \
    php5.6-xmlrpc \
    php5.6-xsl \
    php5.6-zip
When copying the command to an editor for modification, make sure that there are no characters (no spaces) after the \ characters at the end of the lines. The use of indents is optional, I just insert it for the sake of formality to make it obvious that this is a single command. If you use indentation, you can only do this with spaces, because tabs would trigger the command to parse. Bash command line supplement, which stops the entire command from running.

At the end of the command, it writes a few lines of comment:

NOTICE: Not enabling PHP 5.6 FPM by default.
NOTICE: To enable PHP 5.6 FPM in Apache2 do:
NOTICE: a2enmod proxy_fcgi setenvif
NOTICE: a2enconf php5.6-fpm
NOTICE: You are seeing this message because you have apache2 package installed.

In short, PHP-FPM is not enabled by default in Apache, you need to enable the appropriate modules to use it. These will be set later.

This compilation includes the components of a general-purpose PHP system, but if you need more packages, here are the ones apt-cache command to search for all PHP 5.6 packages:

apt-cache search php5.6

From the list you can still make raisins if you need other accessories.

We can check this version with the CLI:

php5.6 --version
PHP 5.6.40-12+0~20190902.20+debian9~1.gbpc72558 (cli) 
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
    with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies

So if you need the command line mode of PHP 5.6, eg. to perform a cron task, etc, then a php5.6 command can be used for this version.

The php.ini files are located in the following locations:

  • CLI: /etc/php/5.6/cli/php.ini
  • PHP-FPM offer: /etc/php/5.6/fpm/php.ini

apt-get -y install \
    php7.0 \
    php7.0-bcmath \
    php7.0-bz2 \
    php7.0-cgi \
    php7.0-cli \

PHP 7.2

To install 7.2 PHP, run the following:

apt-get -y install \
    php7.2 \
    php7.2-bcmath \
    php7.2-bz2 \

It is no longer up from this version php7.x-mcrypt package, so don't look for it. For more details see When creating an Ubuntu LAMP server I have written. I only mention this because there may be websites that CMS systems, who still need this PHP plugin, so these systems do not currently support 7.2 or later PHP.

And finally, to install the current latest PHP version:

apt-get -y install \
    php7.4 \
    php7.4-bcmath \
    php7.4-bz2 \
    php7.4-cgi \

    with Zend OPcache v7.4.0beta4, Copyright (c), by Zend Technologies

As you can see, PHP 7.4 - at the time of writing (2019-09-27) - is still in beta, so don’t use it in a live environment yet. On this change a PHP official site get information.

Update (2020-01-27):
Rounding out the 4 months since writing this description, PHP 7.4 mentioned above is currently: 
PHP 7.4.2 (cli) (built: Jan 23 2020 14:09:40) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.2, Copyright (c), by Zend Technologies

Based on this, you can see that PHP 7.4 has undergone a major development, so now you can use it for live use.

The php.ini files are:

  • CLI: /etc/php/7.4/cli/php.ini
  • PHP-FPM offer: /etc/php/7.4/fpm/php.ini

An independent Based on PHP test the performance of the 7.4 branch looks promising, so we are waiting for the stable release as soon as possible.

 

As you can see, the FPM pools of the different PHP versions have been started, with the default process of 1 + 2 per head waiting for incoming connections. However, our task is not over here, the next page we continue with the parallel use of PHP on a server.
