Here is a brief guide to show you how to install and upgrade to PHP 7.2 on Ubuntu 18.04 LTS with Nginx on Google Cloud


  • Comfortable using LINUX command line interface
  • Your Compute Engine Instance running.

  • Domain name is pointed to your virtual machine.

Install PHP 7.3

sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php7.3-fpm php7.3-common php7.3-mysql php7.3-xml php7.3-xmlrpc php7.3-curl php7.3-gd php7.3-imagick php7.3-cli php7.3-dev php7.3-imap php7.3-mbstring php7.3-opcache php7.3-soap php7.3-zip unzip -y

After the installation has completed, confirm that PHP has installed correctly with this command

php-fpm7.3 -v

Now that PHP 7.3.* has installed and you need to configure the user and group that the service will run under.

sudo nano /etc/php/7.3/fpm/pool.d/www.conf

Change the following lines by replacing the www-data with your username.

user = www-data
group = www-data
listen.owner = www-data = www-data

Now we configure PHP for WordPress by changing some values in php.ini.

sudo nano /etc/php/7.3/fpm/php.ini

Hit F6 for search inside the editor and update the following values

upload_max_filesize = 32M
post_max_size = 48M
memory_limit = 256M
max_execution_time = 600
max_input_vars = 1000
max_input_time = 400

Hit CTRL+X and Y to save the configuration and check if the configuration is correct and restart PHP

sudo php-fpm7.3 -t
sudo service php7.3-fpm restart

Now we have installed PHP 7.3 in Ubuntu 18.04 LTS.

Upgrade to PHP 7.3 – Nginx

Once you have installed and configured PHP 7.3 you can update the Nginx configuration to use PHP 7.3 for your website.

SSH your VM Instance and edit the Nginx configuration file for your website with the following command

sudo nano /etc/nginx/sites-availabale/

Find the line with fastcgi_pass unix:/run/php/php7.2-fpm.sock;

Update the php7.2-fpm.sock to php7.3-fpm.sock

So the output will be

fastcgi_pass unix:/run/php/php7.3-fpm.sock;

Check your configuration and restart Nginx for the changes to take effect

sudo nginx -t
sudo service nginx restart
