If you start XORG it WON'T WORK since the system is in READ-ONLY mode. To solve this problem, move .Xauthority to a READ-WRITE DIRECTORY.

# mkdir /media/data/root
# touch /media/data/root/.Xauthority
# chmod 600 /media/data/root/.Xauthority

Add this to your /etc/rc.local file

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

# Sets .xauthority location file
export XAUTHORITY=/media/data/root/.Xauthority
/usr/bin/startx &
 
sudo modprobe bcm2835-v4l2

If you reboot your raspberry pi you may see that it displays the following errors:

This happens because raspbian Stretch uses libinput as it's mouse drivers instead of the evdev. To solve this, uninstall linunput and replace it by evdev drivers.

# apt install --no-install-recommends xserver-xorg-input-evdev
# apt remove xserver-xorg-input-libinput

# apt install --no-install-recommends lighttpd

Once you have installed the web server, start it and test if there is any error.

# systemctl start lighttpd.service

Get the raspberry pi ip address and access the web server from a different machine (it could be macOS, windows, linux, etc…).

~ ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

First, you need to install PHP-FPM, which is a process manager for PHP.

# apt install --no-install-recommends php7.0-fpm

Then, enable it the typing the following:

# lighttpd-enable-mod fastcgi
# lighttpd-enable-mod fastcgi-php

Now before we can go reloading Lighttpd, we will have to make changes to its configuration. By default, it is configured to work with PHP-CGI and not PHP-FPM, luckily it is easy to make these changes.

Change the content of fastcgi config file to this:

# vi /etc/lighttpd/conf-available/15-fastcgi-php.conf

# -*- depends: fastcgi -*-
# /usr/share/doc/lighttpd/fastcgi.txt.gz
# http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:ConfigurationOptions#mod_fastcgi-fastcgi

## Start an FastCGI server for php (needs the php5-cgi package)
fastcgi.server += ( ".php" =>
        ((
                "socket" => "/var/run/php/php7.0-fpm.sock",
                "broken-scriptfilename" => "enable"
        ))
)

Restart lighttpd to apply the modifications.

# systemctl restart httpd.service

To test the PHP installation, create an index.php file in /var/www/html.

# vi /var/www/html/index.php

<?php
  phpinfo();
?>

And again, test it from a local machine.

Now that PHP is setup, it's time to create a virtual host. In lighttpd, all you need to do is to create a file in /etc/lighttpd/conf-available, in our case it will be easydoor.conf.

# vi /etc/lighttpd/conf-available/easydoor.conf

$HTTP["host"] == "easydoor" { #FDQN
	server.document-root = "/home/acdsn/git/easydoor-scripts/minicentral/intercom/www/html"
}

Don't forget to add easydoor to your hosts file.

# vi /etc/hosts

127.0.0.1	easydoor

Since /var/log is mounted in tmpfs and apache stores its log in /var/log/apache2, apache won't start. Solve this by telling to systemd that it must create that directory at startup.

# vi /etc/tmpfiles.d/apache2.conf
d /var/log/apache2 0750 root root
