[size=large]3. Selfhost[/size] 

(Source: #^[url=http://www.techjawab.com/2013/06/setup-dynamic-dns-dyndns-for-free-on.html]http://www.techjawab.com/2013/06/setup-dynamic-dns-dyndns-for-free-on.html[/url])

[url=http://freedns.afraid.org/signup/]http://freedns.afraid.org/signup/[/url]

[b]Step 1[/b]
Register for a Free domain at #^[url=http://freedns.afraid.org/signup/]http://freedns.afraid.org/signup/[/url]
(We will take techhome.homenet.org in this guide)

[b]Step 2[/b]

Logon to FreeDNS (where you just registered) and goto #^[url=http://freedns.afraid.org/dynamic/]http://freedns.afraid.org/dynamic/[/url]
Right click on "Direct Link" and copy the URL and paste it somewhere.
You should notice a large and unique alpha-numeric key in the URL, make a note of it as shown below:
[code]http://freedns.afraid.org/dynamic/update.php?alphanumeric-key[/code]


[b]Step 3[/b]
Install inadyn using the following command:[code]sudo apt-get install inadyn[/code]

[b]Step 4[/b]
Configure inadyn using the below steps:[code]sudo nano /etc/inadyn.conf[/code]
And add the following contains in it replacing the actual values:
[code]
--username [color=red]techhome[/color]
--password [color=red]mypassword[/color]
--update_period 3600
--forced_update_period 14400
--alias [color=red]techhome.homenet.org</b>,[color=red]alphanumeric key[/color]
--background
--dyndns_system default@freedns.afraid.org
--syslog
 [/code]


[b]Step 5[/b]

Now, we need to ensure that the DNS updater (Inadyn) runs automatically after every re-boot[code]export EDITOR=gedit && sudo crontab -e[/code]
Add the following line:[code]@reboot /usr/sbin/inadyn[/code]


[b]Step 6[/b]

Reboot system and then run the following command to ensure inadyn is running:[code]
sudo reboot
ps -A | grep inadyn
[/code]
Now your host is ready and up for accessing from internet...
You can trying ssh-ing from another computer over the internet
[code]ssh username@techhome.homenet.org[/code]
Or, if any web server is running, then simply browse to  #^[url=http://techhome.homenet.org]http://techhome.homenet.org[/url]
Or, you can just ping it to test ping techhome.homenet.org
To check the logs you can use this:
[code]more /var/log/messages |grep INADYN[/code]


[size=large]4. Install $Projectname[/size] 

(Source: [zrl=[baseurl]/help/Install][baseurl]/help/Install[/zrl])

Linux Appache document root is /var/www/
Two files exist there (created by the steps above): index.html, phpinfo.php


[b]Install $Projectname and its Addons[/b]

Cleanup: Remove the directory www/ (Git will not create files and folders in directories that are not empty.) Make sure you are in directory var[code]pi@pi /var $ cd /var[/code]
 
Remove directory[code]pi@pi /var $ sudo rm -rf www/[/code]

Download the sources of $Projectname from GIT
[code]pi@pi /var $ sudo git clone https://github.com/redmatrix/redmatrix.git www[/code]

Download the sources of the addons from GIT
[code]pi@pi /var/www $ sudo git clone https://github.com/redmatrix/redmatrix-addons.git addon[/code]

Make user www-data the owner of the whole web directory (including subdirectories and files)
(TODO: This step has to be proofed by the next installation.)
[code]pi@pi /var $ chown -R www-data:www-data /var/www/[/code]

Check if you can update the sources from git[code]
pi@pi /var $ cd www
pi@pi /var/www $ git pull
[/code]

Check if you can update the addons
[code]pi@pi /var/www $ cd addon/
pi@pi /var/www/addon $ sudo git pull[/code]

Make sure folder store/[data]/smarty3 exists and is writable by the webserver
[code]pi@pi /var/www $ sudo chmod ou+w "store/\[data\]/smarty3"[/code]

Create .htconfig.php and is writable by the webserver
[code]pi@pi /var/www $ sudo touch .htconfig.php
pi@pi /var/www $ sudo chmod ou+w .htconfig.php[/code]

[b]First start and initial configuration of your RED Matrix hub[/b]

In browser open #^[zrl=http://einervonvielen.mooo.com/]http://einervonvielen.mooo.com/[/zrl]
(Replace einervonvielen.mooo.com by your domain, see chapter selfhost. Be patient. It takes time.)
(#^[zrl=http://einervonvielen.mooo.com/index.php?q=setup]http://einervonvielen.mooo.com/index.php?q=setup[/zrl])

There might be errors like the following.

Error: libCURL PHP module required but not installed.
Solution:
apt-get install php5-curl

Error: Apache webserver mod-rewrite module is required but not installed.
Solution
(Source: [url=http://xmodulo.com/2013/01/how-to-enable-mod_rewrite-in-apache2-on-debian-ubuntu.html]http://xmodulo.com/2013/01/how-to-enable-mod_rewrite-in-apache2-on-debian-ubuntu.html[/url])
The default installation of Apache2 comes with mod_rewrite installed. To check whether this is the case, verify the existence of /etc/apache2/mods-available/rewrite.load
- pi@pi /var/www $ nano /etc/apache2/mods-available/rewrite.load
 (You should find the contendt: LoadModule rewrite_module /usr/lib/apache2/modules/mod_rewrite.so)
To enable and load mod_rewrite, do the rest of steps.
Create a symbolic link in /etc/apache2/mods-enabled
- pi@pi /var/www $ sudo a2enmod rewrite
Then open up the following file, and replace every occurrence of "AllowOverride None" with "AllowOverride all".
- pi@pi /var/www $ sudo nano /etc/apache2/sites-available/default
Finally, restart Apache2.
- pi@pi /var/www $ sudo service apache2 restart

Error store is writable (not checked)
Solution:
(TODO: Make writeable to group www-data only?)
pi@pi /var/www $ sudo mkdir store
pi@pi /var/www $ chown -R www-data:www-data /var/www/red/
pi@pi /var/www $ sudo chmod ou+w view

[b]More[/b]

Set up a cron job to run the poller once every 15 minutes in order to perform background processing.
- pi@pi /var/www $ which php
Make sure you are in the document root directory of the webserver
- pi@pi /var/www $ cd /var/www/
Try to execute the poller in order to make sure it works
- pi@pi /var/www $ /usr/bin/php include/poller.php
Create the cronjob
- pi@pi /var/www $ crontab -e
Enter
- */15 * * * * cd /var/www/; /usr/bin/php include/poller.php
- Save and exit.

Prevent search engines from indexing your search pages. Why?  This can cause heavy resource use.

[code]
php util/config system block_public_search 1
[/code]



[size=large]5. Keep your Raspberry Pi and your $Projectname up-to-date[/size] 

Git update every day at 4 am and addons at 5 am every day
Try if the command is working
- pi@pi /var/www $ sudo git pull
Create the cronjob
- pi@pi /var/www $ crontab -e
Enter the following to update at 4:01 am every day
- 01 04 * * * cd /var/www/; sudo git pull
Enter the following to update the addons at 5:01 am every day
- 01 05 * * * cd /var/www/addon/; sudo git pull
Enter the following to update the Raspberry Pi (Raspbian OS = Debian) at 6:01 am every day
