The procedure to install MongoDB driver, on a PLESK server for PHP version 7.1
For the PLESK environment under UBUNTU, you must first install the development packages for our latest version of PHP. Number 71 corresponds to PHP version 7.1.
apt-get install plesk-php71-dev build-essential
Now, we can install the module mongodb PHP 7.1 with its version PECL.
/opt/plesk/php/7.1/bin/pecl config-set php_prefix /opt/plesk/php/7.1/bin/ /opt/plesk/php/7.1/bin/pecl install mongodb
More information about the procedure with the official documentation of mongodb with PECL.
The successful installation, we must now add in the configuration of php.ini. You have to create a file ** mongodb.ini ** in the php.d folder of your PHP version.
echo "extension=mongodb.so" > /opt/plesk/php/7.1/etc/php.d/mongodb.ini
You need to run the php_settings command from PLESK to update the php.ini configuration of your domains.
plesk bin php_settings -u
