# Description-en: server-side, HTML-embedded scripting language (default)
# PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used
# open source general-purpose scripting language that is especially suited
# for web development and can be embedded into HTML.
# .
# This package is a dependency package, which depends on Ubuntu's default
# PHP version (currently 7.2).
# Description-md5: 778bb04d56a141a57b6ce7e9e2bd3d76
# Supported: 5y
# If you do not get php 7.2 then add below ppa which gives us the latest php version 7.2 then check again
sudo add-apt-repository ppa:ondrej/php
# Lets now install php7.2 and some important modules which we will need.
sudo apt-get install php7.2-cli php7.2-fpm php7.2-curl php7.2-gd php7.2-mysql php7.2-mbstring zip unzip
# Once done all basic modules will be installed now, lets check the version now
php -v
# Lets also check if the PHP7.2-FPM is running, if not started it
sudo service php7.2-fpm status
# If php-fpm is not running
sudo service php7.2-fpm start
# Now we need to configure the Gateway so that PHP-FPM uses the UNIX socket for executing PHP files.
# For this we need to check where is the PHP7.2-fpm service running from and where are their configurations stored
sudo ps aux | grep php # (this will list php process)
# You will see the output something like below depending on how many processes are running
# root 25121 0.0 0.1 427436 25088 ? Ss 11:42 0:00 php-fpm: master process (/etc/php/7.2/fpm/php-fpm.conf)
# www-data 25133 0.0 0.0 429736 12276 ? S 11:42 0:00 php-fpm: pool www
# www-data 25134 0.0 0.0 429736 12276 ? S 11:42 0:00 php-fpm: pool www
# You will see the php-fpm master process is its location as /etc/php/7.2/fpm/php-fpm.conf. We now need to check the socket details
# from the PHP7.2-fpm by view this file.
vim /etc/php/7.2/fpm/php-fpm.conf
# You will see at the end of the file something like 'include=/etc/php/7.2/fpm/pool.d/*.conf' which means this process manager is using configurations from
# the pool.d directory. When viewing the /etc/php/7.2/fpm/pool.d/www.conf you will see that the PHP7.2-fpm (process manager) is
# listening to the socket at 'listen = /run/php/php7.2-fpm.sock'
# Copy the socket location i.e. /run/php/php7.2-fpm.sock and we will use this socket to tell nginx to use this socket
sudo vim /etc/nginx/site-available/default
# You will need to tell NGINX to process the index.php files as well so replace the following line
# index index.html index.htm index.nginx-debian.html;
# to
# index index.html index.htm index.php;
# Also you will see something like the following block for 'location'
#location ~ \.php$ {
# include snippets/fastcgi-php.conf;
#
# # With php-fpm (or other unix sockets):
# fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
# # With php-cgi (or other tcp sockets):
# fastcgi_pass 127.0.0.1:9000;
#}
# Make changes so to the above block so you have the following one:
location ~ \.php$ {
include snippets/fastcgi-php.conf;
#
# # With php-fpm (or other unix sockets):
fastcgi_pass unix:/run/php/php7.2-fpm.sock;
# # With php-cgi (or other tcp sockets):
# fastcgi_pass 127.0.0.1:9000;
}
# Note we have uncommented the location, and fastcgi_pass lines and also pasted the correct socket that
# is used by our php7.2-fpm (process manager)
# lets now login as root and restart both nginx and php7.2-fpm
sudo su
sudo service nginx reload
sudo service php7.2-fpm restart
# Now lets create a index.php file within the document root i.e. root /var/www/html;
touch /var/www/html/index.php
# and put phpinfo() and save it.
# now open http://localhost and you should see the screen with all php informaiton
# You may run into permission issue while creatiing index.php file in /var/www/html/ so inorder to fix then add your current user in www-data group
sudo gpasswd -a "$USER" www-data
# Now whenever you will write a new file then it will have proper permission. In order to change previously created files run -
sudo chown -R "$USER":www-data /var/www
find /var/www -type f -exec chmod 0660 {} \;
sudo find /var/www -type d -exec chmod 2770 {} \;All your project goes inside the /var/www/html directory. BUT it is good practice (and reduce lot of headache of permission) by creating symlink of your project in the html directory.
