Enable PHP-FPM
PHP-FPM is enabled by default. In case you find that it is not, follow these steps to re-enable it:
- 
Enable the PHP-FPM service: $ sudo systemctl enable bitnami.php-fpm
- 
Start PHP-FPM: $ sudo /opt/bitnami/ctlscript.sh start php-fpm
- 
Enable PHP-FPM configuration in Apache. Update the /opt/bitnami/apache/conf/httpd.conf file and disable the php7 module: #LoadModule php7_module modules/libphp7.so
- 
In the same file, disable the mpm_prefork module: #LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
- 
In the same file, enable the mpm_event module: LoadModule mpm_event_module modules/mod_mpm_event.so
- 
Restart Apache: $ sudo /opt/bitnami/ctlscript.sh restart apache
