Development and put on production of Drupal 8 sites is moving really fast, and demanding sites are always going to require strong search engines to quickly process thousands  of search requests to their sites. On this tutorial I'm going to show you how to install an Apache Solr server to index any Drupal 8 data for fast search queries and results. Drupal 7 sites will also benefit of this since we are taking advantage of the Search API and Search API Solr modules integration.

Drupal 8 requires a minimum version of Solr 4.x so for this tutorial we'll be using 4.5.1, we'll be also configuring our installation using Jetty 9 (a servlet…

On this post I'll show you how to run Drupal 8 or any PHP application using Apache HTTP Server with mod_event enabled and PHP 7-FPM

First we need to get the required PHP and Apache packages from the Ubuntu repository:

$sudo apt-get install php7.0-fpm apache2 libapache2-mod-fastcgi

then we need to disable the worker that's enabled by default and switch to mpm_event:

$sudo a2dismod mpm_worker
$sudo a2enmod mpm_event

Now that we have enabled the event module, let's activate some required extra apache modules needed to run our apps like Drupal:

$sudo a2enmod alias rewrite fastcgi expires headers remoteip ssl actions

We need to create a config file for PHP-FPM so apache is aware of how to treat it:

$sudo nano /etc/apache2/conf-available/php-fpm.conf
