Running Multiple versions of PHP 5.6 and 7.2 on Nginx (Ubuntu)
After the launch of PHP 7, Every one wanted to move, to the latest version due to its performance and features.However its not easy to move all old legacy code in PHP 5 to PHP 7 easily. So often we have to run two servers one with PHP 5 and another with PHP 7 and move the sites one by one. This requires extra time and money.
However now with Ubuntu 16.04 and above and also other latest linux distro, you can run both PHP version simultaneously.
Here, I will setup both PHP 7 and PHP 5.6 on nginx.
Step 1 : Update the Package
sudo apt update
Step 2 : Install software-properties-common
sudo apt install software-properties-common
Step 3: Add Ondřej’s PHP repository to download multiple versions of PHP 5.6 and PHP 7.x, and update again
sudo add-apt-repository ppa:ondrej/php
sudo apt update
Step 4: Now install the version of PHP you require. Ondřej’s repository provides PHP 5.6 and PHP 7.x. In this example we will install PHP 5.6 and PHP 7.2.
sudo apt install php5.6 php5.6-fpm
sudo apt install php7.2 php7.2-fpm
Step 5: You can check the installation by droping down the folder.
ls /var/run/php/
output:
total 8
-rw-r--r-- 1 root root 4 Feb 17 16:50 php5.6-fpm.pid
srw-rw---- 1 www-data www-data 0 Feb 17 16:50 php5.6-fpm.sock
-rw-r--r-- 1 root root 5 Feb 17 16:51 php7.2-fpm.pid
srw-rw---- 1 www-data www-data 0 Feb 17 16:51 php7.2-fpm.sock
Step 6: Now you can install all the PHP extension required for, like MYSQL, Curl, XML etc required.
ls /var/run/php/
output:
sudo apt install php-mysql
sudo apt install php5.6-mysql
sudo apt install php5.6-curl
sudo apt install php7.2-curl
sudo apt install php7.2-xml
sudo apt install php5.6-xml
Step 7: Now open your nginx virtualhost conf file and edit
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
}
Step 8: create two php info page in the location and you can check that both PHP are running simultaneously.
