Lets set up our map server with local cached image files
 
  
== Installing required software ==
 
 
Install nginx (server), hostapd (wifi AP host), dnsmasq (light dns server)
 
[http://elinux.org/RPi_Nginx_Webserver install Nginx]
 
<nowiki>
 
sudo apt-get update
 
sudo apt-get install nginx
 
sudo apt-get install hostapd
 
sudo apt-get install dnsmasq
 
</nowiki>
 
 
== Web Server ==
 
 
Set up web server to forward 404's to root directory (needed for captive portal behaviour) and start
 
edit /etc/nginx/sites-available/default
 
 
and modify line in "location / {" section:
 
<nowiki>
 
try_files $uri $uri/ = 404;
 
</nowiki>
 
becomes
 
<nowiki>
 
try_files $uri $uri/ /index.html;
 
</nowiki>
 
 
Now start the server
 
<nowiki>
 
sudo service nginx start
 
</nowiki>
 
 
== Set up hostapd ==
 
 
Set up AP with hostap (instructions from [http://elinux.org/RPI-Wireless-Hotspot set up AP with udhcpd])
 
edit the file /etc/hostapd/hostapd.conf
 
<nowiki>
 
interface=wlan0
 
ssid=TacticalSpaceLab
 
hw_mode=g
 
channel=6
 
auth_algs=1
 
wmm_enabled=0
 
</nowiki>
 
Edit the file /etc/default/hostapd and change the line:
 
<nowiki>
 
#DAEMON_CONF=""
 
</nowiki>
 
to
 
<nowiki>
 
DAEMON_CONF="/etc/hostapd/hostapd.conf"
 
</nowiki>
 
Start it up, and add it to start at boot
 
<nowiki>
 
sudo service hostapd start
 
sudo update-rc.d hostapd enable
 
</nowiki>
 
 
=== Note for EDIMAX adaptors ===
 
 
[http://www.daveconroy.com/turn-your-raspberry-pi-into-a-wifi-hotspot-with-edimax-nano-usb-ew-7811un-rtl8188cus-chipset/ edimax version of hostapd if using an edimax wifi usb]
 
 
 
== DHCP and DNS for access point and captive portal ==
 
 
Set up /etc/network/interfaces for serving DHCP and DNS
 
<nowiki>
 
auto lo
 
iface lo inet loopback
 
 
auto wlan0
 
iface wlan0 inet static
 
  address 10.1.2.1
 
  netmask 255.255.255.0
 
  network 10.1.2.0
 
 
</nowiki>
 
# configure dnsmasq /etc/dnsmasq.conf
 
<nowiki>
 
# captive portal to this
 
no-resolv
 
server=/localnet/10.1.2.1
 
server=/tacticalspace/10.1.2.1
 
address=/#/10.1.2.1
 
interface=wlan0
 
dhcp-range=10.1.2.5,10.1.2.200,12h
 
</nowiki>
 
# restart dnsmasq
 
<nowiki>
 
sudo /etc/init.d/dnsmasq restart
 
</nowiki>
 
 
# if you want dnsmarsq script logging...
 
Create /var/log/dhcp_leases file with write
 
create /usr/bin/logdhcp, make executable
 
add it to dnsmasq config
 
<nowiki>
 
#!/bin/bash
 
destfile=/var/log/dhcp_leases
 
#if [ "$1" == "add" ]
 
#then
 
  if [ -f "$destfile" ]
 
  then
 
    echo "$1 $2" >> "$destfile"
 
  fi
 
#fi
 
</nowiki>

ended up using dnsmasq for DNS and DHCP.  Setting DNS forward IP to local for captive portal setup
 
 
== Map framework ==
 
 
Copy the server framework files across
 
 
[http://www.raspberrypi.org/forums/viewtopic.php?f=36&t=39225 some popup mehods]
 
 
place javascript files and map tiles into /var/www/html
 
 
[http://maps.tacticalspace.org/var-MQ-Feb2015.zip MQ var directory archive]
 
 
Remember to make all /var/www/html folders readable with:
 
<nowiki>
 
sudo find /var/www/html -type d -exec chmod a+x {} +
 
sudo find /var/www/html -type d -exec chown root:root {} +
 
sudo find /var/www/html -type f -exec chmod a+r {} +
 
sudo find /var/www/html -type f -exec chown root:root {} +
 
</nowiki>
