Found this article very helpful for setting up DHCP (https://learn.adafruit.com/setting-up-a-raspberry-pi-as-a-wifi-access-point/install-software)

Requirements

A raspberry pi with raspbian running on it. You will need to ssh into it to set this up.

The Packages required for the WebGUI are:

• lighttpd
• php5-cgi
• isc-dhcp-server
• git

Steps

1. Install required packages

sudo apt-get install lighttpd php5-cgi git isc-dhcp-server 2. Enable php in lighttpd

sudo lighty-enable-mod fastcgi-php
sudo service lighttpd restart

3. Edit /etc/sudoers to allow the www-data user to call the necessary commands. Add the following line to the end of the file.

www-data ALL=(ALL) NOPASSWD:/sbin/ifdown wlan0,/sbin/ifup wlan0,/bin/cat /etc/wpa_supplicant/wpa_supplicant.conf,/bin/cp /tmp/wifidata /etc/wpa_supplicant/wpa_supplicant.conf,/sbin/wpa_cli scan_results,/sbin/wpa_cli scan,/bin/cp /tmp/hostapddata /etc/hostapd/hostapd.conf,/etc/init.d/hostapd start,/etc/init.d/hostapd stop,/etc/init.d/dnsmasq start,/etc/init.d/dnsmasq stop,/bin/cp /tmp/dhcpddata /etc/dnsmasq.conf

4. Once those modifications are done, git clone the files to /var/www. Make sure that there are no files in the /var/www directory. There was a default lighttpd index file that I had to delete.

sudo git clone https://github.com/rjpcomputing/raspap-webgui.git /var/www 5. Set the files ownership to www-data user.

sudo chown -R www-data:www-data /var/www 6. Configure a static IP for the Pi

• Edit /etc/network/interfaces

sudo nano /etc/network/interfaces

• Find and remove dhcp entry iface eth0 inet dhcp
• Append new network settings

auto eth0
allow-hotplug eth0
iface eth0 inet static
address 10.0.0.1
netmask 255.255.255.0
dns-nameservers 8.8.8.8 8.8.4.4

• Find and change iface wlan0 inet manual to iface wlan0 inet dhcp. This is under the wlan0 setup.
• Comment out iface default inet dhcp and allow-hotplug wlan0 using the '#' character at the beginning of the line(s).
• Example of /etc/network/interfaces after all changes are made:

auto lo
iface lo inet loopback

#iface eth0 inet dhcp
auto eth0
allow-hotplug eth0
iface eth0 inet static
address 10.0.0.1
netmask 255.255.255.0
dns-nameservers 8.8.8.8 8.8.4.4

auto wlan0
#allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
#iface default inet dhcp

7. Configure dhcpd by editing /etc/dhcp/dhcpd.conf

• sudo nano /etc/dhcp/dhcpd.conf
• Add the following to the end of the file

subnet 10.0.0.0 netmask 255.255.255.0 
{
  range 10.0.0.50 10.0.0.99;
  option routers 10.0.0.254;
  option domain-name "local";
  option domain-name-servers 8.8.8.8, 8.8.4.4;
}

8. Open /etc/default/isc-dhcp-server and change the INTERFACES="" to INTERFACES="eth0"

sudo nano /etc/default/isc-dhcp-server 9. Install and configure the auto-reconnect WiFi script (wifi-check).

• Copy 'wifi-check' to /usr/local/bin/wifi-check

  • sudo cp /var/www/wifi-check /usr/local/bin/wifi-check
  • sudo chmod +x /usr/local/bin/wifi-check

• Add it to cron so it runs every 5 minutes

  • sudo crontab -e
  • Append the line */5 * * * * /usr/local/bin/wifi-check > /tmp/wificheck.log 2>&1 to the end of the file
  • Save the file

• Reboot and it should be up and running!

  sudo reboot
