Let’s say you’re running nginx, with PHP 5 (fpm, that is) – and want to upgrade to the all-new PHP 7 (which was released on about the 4th December, 2015 – today, incidentally). Here’s how you do it – on Ubuntu, at least:
Right. To keep up with updates, let’s first add the PPA:
sudo apt-get install python-software-properties
then
sudo add-apt-repository ppa:ondrej/php-7.0
Next, let’s remove PHP 5 from our system, and install PHP 7:
sudo apt-get update && sudo apt-get purge php5-fpm
sudo apt-get --purge autoremove
sudo apt-get install php7.0-fpm php7.0-mysql
Now, PHP 5 should be removed and PHP 7 running. However, because the socket used with the new PHP 7 has changed, we’ll need to modify where we send the requests to with nginx.
The old statement for passing it to the socket was
fastcgi_pass unix:/var/run/php5-fpm.sock;
Find this line in your nginx config, and change it to:
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
Okay, now our config is all set. Let’s now restart nginx with
sudo service nginx restart
— and then we’re done! It should be all up and running!
