2. Server Script (PHP 7.2)
To install PHP7.2, execute following command
apt install php7.2 -y
I am installing following commonly used extensions
apt install php7.2-common php7.2-mbstring php7.2-soap php7.2-gd php7.2-xml php7.2-intl php7.2-mysql php7.2-zip php7.2-curl php7.2-fpm -y
To install php7.2-mcrypt, follow this tutorial from lukasmestan.com and below is summary of commands:
apt -y install gcc make autoconf libc-dev pkg-config
apt -y install libmcrypt-dev
pecl install mcrypt-1.0.1
Note: If you notice message such as E: Unable to locate package php7.2 then add ondrej PPA repository by executing add-apt-repository -y ppa:ondrej/php
To install php7.3-mcrypt, follow same steps as explained above for php7.2-mcrypt but change mcrypt version:
apt -y install gcc make autoconf libc-dev pkg-config
apt -y install libmcrypt-dev
pecl install mcrypt-1.0.2
If you get issue such as mentioned below:
sh: 1: phpize: not found
ERROR: 'phpize' failed`
then install respective dev extension. For php7.2, execute command - apt install php7.2-dev -y and for php7.3, execute command - apt install php7.3-dev -y and then continue installing mcrypt.
You should activate it once installation is completed. After installation, you'll be given path such as /usr/lib/php/20180731/mcrypt.so or /usr/lib/php/20170718/mcrypt.so depending upon your PHP API. Note down it as we'll use it later.
Now, go to your installed PHP directory i.e. /etc/php/7.3/mods-available or /etc/php/7.2/mods-available and then copy any existing .ini file (I'll choose mbstring - cp mbstring.ini mcrypt.ini) and paste /usr/lib/php/<version>/mcrypt.so path as extension i.e. extension=/usr/lib/php/20180731/mcrypt.so.
Then execute following commands (Replace x with your PHP version):
cd /etc/php/7.x/fpm/conf.d && ln -s /etc/php/7.x/mods-available/mcrypt.ini 20-mcrypt.ini
cd /etc/php/7.x/cli/conf.d && ln -s /etc/php/7.x/mods-available/mcrypt.ini 20-mcrypt.ini
service php7.x-fpm restart
Useful commands:
php -i | grep "mcrypt"
php -v # To get PHP cli version
php --ini # To get loaded ini file location
