Le but de cette étape est d'avoir un environnement permettant l'utilisation de plusieurs versions de PHP en parallèle (le tout avec Apache). The goal here is to be able to run Apache/PHP with multiple PHP installed on the machine, letting you a way to choose which version you want to run.
To be do that, we need to compile our own PHP.
First, be sure to grab all the dependencies
apt-get install build-essential libxml2-dev autoconf2.13 libpng12-* zlib1g gawk bison flex ^libxml2-* mcrypt libmcrypt-dev perl libcurl4-gnutls-dev libicu-dev libxslt1-dev
We also need the JPEG lib
apt-get install libjpeg62-dev
And the OpenSSL lib.
apt-get install libcurl4-openssl-dev
Then, we need Apache and Apache MPM Worker
apt-get install apache2 apache2-mpm-worker
We also need Apache's mod_fastcgi If you try to run
apt-get install libapache2-mod-fastcgi
You'll get an error
E: Package 'libapache2-mod-fastcgi' has no installation candidate
This is perfectly normal since the fastcgi package is in the "non-free" repository of debian.
We need to add those one
vim /etc/apt/sources.list
Add those 2 lines :
deb http://ftp.fr.debian.org/debian/ wheezy non-free
deb-src http://ftp.fr.debian.org/debian/ wheezy non-free
Save, quit
Don't forget to update !
apt-get update
Now, you can try again :
apt-get install libapache2-mod-fastcgi
Then you'll need also those libs
apt-get install libreadline-dev libfreetype6-dev
It should now be good for Apache, at least for now.
Next, PHP ! As said before, we'll need to compile our PHP. So, grab the sources : http://php.net/downloads.php We'll start with version 5.5 (5.5.4 right now)
cd /opt
mkdir src
cd src
wget http://fr2.php.net/get/php-5.5.4.tar.gz/from/this/mirror
mv mirror php-5.5.4.tar.gz
tar xvfz mirror php-5.5.4.tar.gz
cd php-5.5.4
Next, configure !
./configure \
--prefix=/opt/php5.5.4 \
--with-readline \
--enable-cli \
--with-mysql=mysqlnd \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-gd \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib-dir \
--enable-gd-native-ttf \
--with-curl \
--enable-bcmath \
--enable-mbstring \
--enable-exif \
--enable-pcntl \
--enable-soap \
--with-xsl \
--enable-zip \
--with-config-file-path=/opt/php5.5.4/conf \
--with-config-file-scan-dir=/opt/php5.5.4/conf.d \
--with-iconv-dir=/opt/local \
--enable-fpm \
--with-fpm-user=www-data \
--with-fpm-group=www-data
You need to be carfeful with the paths (/opt/php5.5.4/xxx) right here. It is used to be able to say PHP when it should be installed and where the configuration files are looked for.
(here, you can grab a little coffee)
Then, the make !
make
(Here, you can grab a big coffee)
Then, install it !
make install
Just check that everything is there. Just go :
cd /opt/php5.5.4/
You should find :
ls /opt/php5.5.4
bin etc include lib php sbin var
Now, we need to make some changes in the php-fpm configuration file.
Thankfully, PHP have an example file we could use :
cp /opt/php5.5.4//etc/php-fpm.conf.default /opt/php5.5.4/etc/php-fpm.conf
Edit this file :
vim /opt/php5.5.4/etc/php-fpm.conf
Here are the changes you need to do : In [global], uncomment
pid = run/php-fpm.pid
And in the "Pool Definitions", you'll find the line :
listen = 127.0.0.1:9000
Change this one to :
listen = /var/run/php-fpm-5.5.4.sock
This will allow us not to "plug" PHP to an IP:PORT, but to an unix socket. Save and quit.
We'll also need a basic php.ini file. Once again, PHP have one (in the souces) :
cd /opt/php5.5.4
mkdir conf
cp /opt/src/php-5.5.4/php.ini-development /opt/php5.5.4/conf/
We'll also need a startup script.
cp /opt/src/php-5.5.4/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm5.5.4
Be sure the script is executable
chmod +x /etc/init.d/php-fpm5.5.4
Next, we'll go back to Apache configuration
Be sure that the "actions" and "fastcgi" extensions are enable
a2enmod actions fastcgi
Now, we need to change the mod_fastcgi configuration to fits our needs
cd /etc/apache2/mods-enabled/
vim fastcgi.conf
This file needs to be changes to that :
<IfModule mod_fastcgi.c>
AddHandler fastcgi-script .fcgi
FastCgiIpcDir /var/lib/apache2/fastcgi
FastCgiConfig -autoUpdate -singleThreshold 100 -killInterval 300 -maxProcesses 10 -maxClassProcesses 1
AddHandler php5-fcgi .php
AddType application/x-httpd-php .php
ScriptAlias /fastcgi/ /var/www/fastcgi/
<Directory "/var/www/fastcgi">
Options +ExecCGI
SetHandler fastcgi-script
Order Deny,Allow
Allow from env=REDIRECT_STATUS
</Directory>
<Location "/fastcgi/php5.fpm">
Order Deny,Allow
Deny from all
Allow from env=REDIRECT_STATUS
</Location>
FastCgiExternalServer /var/www/fastcgi/php5.fpm -socket /var/run/php-fpm-5.5.4.sock
Action php5-fcgi /fastcgi/php5.fpm
</IfModule>
The important part here is FastCgiExternalServer /var/www/fastcgi/php5.fpm -socket /var/run/php-fpm-5.5.4.sock
The last part (-socket /var/run/php-fpm-5.5.4.sock) is the same that we have changed before in the "/opt/php5.5.4/etc/php-fpm.conf" file.
About the /var/www/fastcgi/php5.fpm<, the directory "fastcgi" needs to exist. It can be empty, but it really need to exist. So, let's create it :
mkdir /var/www/fastcgi/
Et voilà, let's test it now !
Add a php file in /var/www
vim /var/www/index.php
With just a simple phpinfo() in it
<?php phpinfo();
Start Apache and php-fpm
/etc/init.d/apache2 restart
/etc/init.d/php-fpm5.5.4 restart
Now, with your broswer, go check that everything works.
http:///index.php You should see "PHP Version 5.5.4"
We now have our Apache/PHP working. But what about adding a PHP 5.3 now ?
Compile it !
cd /opt/src/
wget http://fr2.php.net/get/php-5.3.27.tar.gz/from/this/mirror
mv mirror php-5.3.27.tar.gz
tar xvfz php-5.3.27.tar.gz
cd php-5.3.27
Don't forget to change the paths
./configure \
--prefix=/opt/php5.3.27 \
--with-readline \
--enable-cli \
--with-mysql=mysqlnd \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-gd \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib-dir \
--enable-gd-native-ttf \
--with-curl \
--enable-bcmath \
--enable-mbstring \
--enable-exif \
--enable-pcntl \
--enable-soap \
--with-xsl \
--enable-zip \
--with-config-file-path=/opt/php5.3.27/conf \
--with-config-file-scan-dir=/opt/php5.3.27/conf.d \
--with-iconv-dir=/opt/local \
--enable-fpm \
--with-fpm-user=www-data \
--with-fpm-group=www-data
make
(coffee)
make install
cd /opt/php5.3.27/
cp /opt/php5.3.27/etc/php-fpm.conf.default /opt/php5.3.27/etc/php-fpm.conf
vim /opt/php5.3.27/etc/php-fpm.conf
As before, change the values :
pid = run/php-fpm.pid
And of course, change the socket (use an other one)
listen = /var/run/php-fpm-5.3.27.sock
php.ini and startup script :
cd /opt/php5.3.27
mkdir conf
cp /opt/src/php-5.3.27/php.ini-development /opt/php5.3.27/conf/
cp /opt/src/php-5.3.27/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm5.3.27
chmod +x /etc/init.d/php-fpm5.3.27
We also need to make an other change in the fastcgi.conf file :
vim /etc/apache2/mods-enabled/fastcgi.conf
See the line
FastCgiExternalServer /var/www/fastcgi/php5.fpm -socket /var/run/php-fpm-5.5.4.sock
Add an other one, just below
FastCgiExternalServer /var/www/fastcgi/php5.3.fpm -socket /var/run/php-fpm-5.3.27.sock
We should have :
<IfModule mod_fastcgi.c>
AddHandler fastcgi-script .fcgi
FastCgiIpcDir /var/lib/apache2/fastcgi
FastCgiConfig -autoUpdate -singleThreshold 100 -killInterval 300 -maxProcesses 10 -maxClassProcesses 1
AddHandler php5-fcgi .php
AddType application/x-httpd-php .php
ScriptAlias /fastcgi/ /var/www/fastcgi/
<Directory "/var/www/fastcgi">
Options +ExecCGI
SetHandler fastcgi-script
Order Deny,Allow
Allow from env=REDIRECT_STATUS
</Directory>
<Location "/fastcgi/php5.fpm">
Order Deny,Allow
Deny from all
Allow from env=REDIRECT_STATUS
</Location>
FastCgiExternalServer /var/www/fastcgi/php5.fpm -socket /var/run/php-fpm-5.5.4.sock
FastCgiExternalServer /var/www/fastcgi/php5.3.fpm -socket /var/run/php-fpm-5.3.27.sock
Action php5-fcgi /fastcgi/php5.fpm
</IfModule>
That it ! How to choose which PHP version you want to use ? Easy, just go in your Apache Virtualhost, and change the "Action php5-fcgi /fastcgi/php5.fpm" to the right fastcgi server. Example with the basic virtualhost
vim /etc/apache2/sites-enabled/000-default
Before , add
Action php5-fcgi /fastcgi/php5.3.fpm
So we have :
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
Action php5-fcgi /fastcgi/php5.3.fpm
</VirtualHost>
Save and quit.
Launch all you php-fpm and Apache
/etc/init.d/php-fpm5.5.4 restart
/etc/init.d/php-fpm5.3.27 restart
/etc/init.d/apache2 restart
Now, if you go on http:///index.php, you should see "PHP Version 5.3.27"
Et voilà !
