+[/list]

+

+

+[h2]Install Apache Webserver[/h2]

+

+Open a terminal and make yourself root

+[code]su -l[/code]

+

+Create the standard group for the Apache webserver

+[code]groupadd www-data[/code]

+

+[b]Enable rewrite[/b]

+

+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

+

+[code]

+root@debian /var/www $ nano /etc/apache2/mods-available/rewrite.load

+[/code]

+

+ (You should find the content: 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

+

+[code]

+cd /var/www

+root@debian /var/www $ a2enmod rewrite

+[/code]

+

+Then open up the following file, and replace every occurrence of "AllowOverride None" with "AllowOverride all".

+

+[code]

+root@debian /var/www $nano /etc/apache2/apache2.conf

+[/code]

+or

+[code]

+root@debian:/var# gedit /etc/apache2/sites-enabled/000-default 

+[/code]

+

+Finally, restart Apache2.

+

+[code]

+root@debian /var/www $service apache2 restart

+[/code]

+

+[b]Test installation[/b]

+

+[code]cd /var/www[/code]

+

+create a php file to test the php installation[code]nano phpinfo.php[/code]

+

+Insert into the file:

+[code]

+<?php

+  phpinfo();

+?>

+[/code]

+(save CTRL+0, ENTER, CTRL+X)

+

+open webbrowser on PC and try #^[url=http://localhost/phpinfo.php]http://localhost/phpinfo.php[/url] (page shows infos on php)

+

+connect phpMyAdmin with MySQL database [code]nano /etc/apache2/apache2.conf

+[/code]

+- CTRL+V... to the end of the file

+- Insert at the end of the file:  (save CTRL+0, ENTER, CTRL+X)[code]Include /etc/phpmyadmin/apache.conf[/code]

+

+restart apache

+[code]/etc/init.d/apache2 restart

+apt-get update

+apt-get upgrade

+reboot[/code]

+

+[b]phpMyAdmin[/b]

+

+open webbrowser on PC and try #^[url=http://localhost/phpmyadmin]http://localhost/phpmyadmin[/url]

+

+(Source #^[url=http://www.manfred-steger.de/tuts/20-der-eigene-webserver-mit-dem-raspberry-pi#]http://www.manfred-steger.de/tuts/20-der-eigene-webserver-mit-dem-raspberry-pi#[/url])

+

+

+[b]Create an empty database... that is later used by RED[/b]

+

+open webbrowser on PC and try #^[url=http://localhost/phpmyadmin]http://localhost/phpmyadmin[/url]

+

+Create an empty database, for example named "red".

+Create a database user, for example "red".

+Grant all rights for the user "red" to the database "red".

+

+Note the access details (hostname, username, password, database name).

+

+

+[h2]Fork the project on github to be able contribute[/h2]

+

+Please follow the instruction in offiical [url=http://git-scm.com/book/en/v2/GitHub-Contributing-to-a-Project] documentation[/url] of git.

+It is a good idea to read the whole manual! Git is different to other version control systems in many ways.

+

+You should

+[list]

+[*] create an account at github.com

+[*] fork https://github.com/friendica/red

+[*] fork https://github.com/friendica/red-addons

+[/list]

+

+

+[h2]Install RED and its Addons[/h2]

+

+You should have created an account on github and forked the projects befor you procced.

+

+Delete the directory www

+[code]root@debian /var/www/html $ cd ..

+rm -R www/

+[/code]

+

+Install git (and optionally git-gui a client gui)

+[code]apt-get install git git-gui[/code]

+

+Download the main project red and red-addons

+[code]

+root@debian:/var# git clone https://github.com/einervonvielen/red www

+root@debian:/var# cd www/

+root@debian:/var/www# git clone https://github.com/einervonvielen/red-addons addon

+[/code]

+

+Make this extra folder

+[code]

+root@debian:/var/www# mkdir -p "store/[data]/smarty3"

+[/code]

+

+Create .htconfig.php and make it writable by the webserver

+[code]

+root@debian:/var# cd www/

+root@debian:/var/www# chmod ou+w .htconfig.php

+[/code]

+

+Make user www-data (webserver) is the owner all the project files

+[code]

+root@debian:/var/www# cd ..

+root@debian:/var# chown -R www-data:www-data www/

+[/code]

+

+Add yourself ("surfer" in this example) to the group www-data. Why? Later you want to modify files in eclipse or in another editor.

+Then make all files writable by the group www-date you are now a member of.

+[code]

+root@debian:/var/www# usermod -G www-data surfer

+root@debian:/var# chmod -R  g+w www/

+[/code]

+

+Restart the computer (or vm)

+If you are still not able to modify the project files you can check the members of the group www-data with

+[code]

+cat /etc/group

+[/code]

+

+Open http://localhost and init the matrix

+

+Befor you register a first user switch off the registration mails.

+Open /var/www/.htconfig.php

+and make sure "0" is set in this line

+[code]

+$a->config['system']['verify_email'] = 0;

+[/code]

+You should be able to change the file as "yourself" (instead of using root or www-data).

+

+Important!

+Run the poller  to pick up the recent "public" postings of your friends

+Set up a cron job or scheduled task to run the poller once every 5-10

+minutes to pick up the recent "public" postings of your friends

+

+[code]

+crontab -e

+[/code]

+

+Add

+[code]

+*/10 * * * * cd /var/www/; /usr/bin/php include/poller.php

+[/code]

+

+If you don't know the path to PHP type

+[code]

+whereis php

+[/code]

+

+

+[h2]Debug the server via eclipse[/h2]

+

+[h3]Check the configuration of xdebug[/h3]

+

+You shoud already have installed xdebug in the steps befor

+[code]

+apt-get install php5-xdebug

+[/code]

+

+Configuring Xdebug

+

+Open your terminal and type as root (su -l)

+[code]

+gedit /etc/php5/mods-available/xdebug.ini

+[/code]

+

+if the file is empty try this location

+[code]

+gedit /etc/php5/conf.d/xdebug.ini

+[/code]

+

+That command should open the text editor gedit with the Xdebug configuration file

+At the end of the file content append the following text

+

+xdebug.remote_enable=on

+xdebug.remote_handler=dbgp

+xdebug.remote_host=localhost

+xdebug.remote_port=9000

+

+Save changes and close the editor.

+In you terminal type to restart the web server.

+[code]

+service apache2 restart

+[/code]

+

+

+[h3]Install Eclipse and start debugging[/h3]

+

+Install eclipse.

+Start eclipse with default worspace (or as you like)

+

+Install the PHP plugin

+Menu > Help > Install new software...

+Install "PHP Developnent Tools ..."

+

+Configure the PHP plugin

+Menu > Window > Preferences...

+> General > Webbrowser > Change to "Use external web browser"

+> PHP > Debug > Debug Settings > PHP Debugger > Change to "XDebug"

+

+Create a new PHP project

+Menu > File > New Project > Choose PHP > "PHP Project"

+> Choose Create project at existing location and "/var/www"

+

+Start debugging

+Open index.php and "Debug as..."

+Choose as Launch URL: "http://localhost/"

+

+Expected:

+[list]

+[*] The web browser starts

+[*] The debugger will stop at the first php line

+[/list]

+

+

+[h2]Contribute your changes via github[/h2]

+

+(There is a related page in this docs: [zrl=[baseurl]/help/git_for_non_developers]Git for Non-Developers[/zrl])

+As stated befor it is recommended to read the official documentation [url=http://git-scm.com/book/en/v2/GitHub-Contributing-to-a-Project]GitHub-Contributing-to-a-Project[/url] of git.

+

+Make sure you have set your data

+[code]

+surfer@debian:/var/www$ git config --global user.name "Your Name"

+surfer@debian:/var/www$ git config --global user.email "your@mail.com"

+[/code]

+

+Create a descriptive topic branch

+[code]

+surfer@debian:/var/www$ git checkout -b dev_beginning

+[/code]

+

+Make sure your local repository is up-to-date with the main project.

+Add the original repository as a remote named “upstream” if not done yet

+[code]

+surfer@debian:/var/www$ git remote add upstream https://github.com/friendica/red

+[/code]

+

+Fetch the newest work from that remote

+[code]

+surfer@debian:/var/www$ git fetch upstream

+surfer@debian:/var/www$ git merge upstream/master

+[/code]

+

+Hint: You can list the branches

+[code]

+surfer@debian:/var/www$ git branch -v

+[/code]

+

+Make your changes. In this example it is a new doc file.

+

+Check your modifications

+[code]

+surfer@debian:/var/www$ git status

+[/code]

+

+Add (stage) the new file

+[code]

+surfer@debian:/var/www$ git add doc/dev_beginner.bb

+[/code]

+

+Commit the changes to your local branch. This will open an editor to provide a message.

+[code]

+surfer@debian:/var/www$ git commit -a

+[/code]

+

+Push back up to the same topic branch online

+[code]

+surfer@debian:/var/www$ git push

+[/code]

+

+Now you can go to your (online) account at github and create the pull request.

+

+In case the main devolpers want you to change something.

+Make the changes, check them, commit (to local repository), push (to online repository)

+[code]

+surfer@debian:/var/www$ git status

+surfer@debian:/var/www$ git commit -a -m "added modification of branch"

+surfer@debian:/var/www$ git push origin dev_beginning

+[/code]
