Note: this post call also be used to install
php7.3, just change every reference to
It should also work for php 8.0 but I will test that when php 8 is officially released.
Check if you can install php 7.4
To check if php 7.4 is available run:
sudo apt install --dry-run php7.4
If you get an error continue, if you don’t get an error continue to actual install php
As the php version is not available
We are going to create a new source for php. We do this with the following 3 commands.
sudo wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg echo "deb https://packages.sury.org/php/ buster main" | sudo tee /etc/apt/sources.list.d/php.list sudo apt update
Actual install php
Now we are ready to install
php7.4 with all modules we need:
sudo apt install -y php7.4-common php7.4-fpm php7.4-cli php7.4-curl php7.4-json php7.4-mysql php7.4-opcache php7.4-gd php7.4-sqlite3 php7.4-mbstring php7.4-zip php7.4-readline php-pear
When done check it with
php -v it should show a php 7.4.0 or higher.
Now we need to add a few fpm things for nginx to work properly.
Create a extra config file
sudo nano /etc/php/7.4/fpm/conf.d/90-pi-custom.ini.
cgi.fix_pathinfo=0 upload_max_filesize=64m post_max_size=64m max_execution_time=600
Finally reload php
sudo service php7.4-fpm reload
Now PHP is ready to use
