From a5766534fef52da92ddedc8e04008b6b4107c209 Mon Sep 17 00:00:00 2001 From: Einer von Vielen Date: Tue, 6 Jan 2015 16:22:30 +0100 Subject: Mainly it shows how to debug the red matrix (php) in a virtual machine and contribute changes via git. It will guide to the following steps: - Install a Virtual Machine - Install Apache Web Server - Install PHP, MySQL, phpMyAdmin - Fork the project on github to be able contribute - Install the RED Matrix - Debug the server via eclipse - Contribute your changes via github --- doc/dev_beginner.bb | 393 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 393 insertions(+) create mode 100644 doc/dev_beginner.bb diff --git a/doc/dev_beginner.bb b/doc/dev_beginner.bb new file mode 100644 index 000000000..83c9dbb39 --- /dev/null +++ b/doc/dev_beginner.bb @@ -0,0 +1,393 @@ +[h2]You want to contribute to the Red Matrix?[/h2] +[b]...and don't know really how to start? +Then this is for you...[/b] + +You want to lean how to: +[list] +[*] debug the Red Matrix, +[*] contribute code to the project, +[*] optionally - do it all from inside a virtual machine? +[/list] + +This manual was tested for +[list] +[*] Lubuntu Linux as host OS +[*] Debian as guest OS running in a VM +[/list] + +[h2]Content[/h2] + +In this manual you will +[list=1] +[*] Install a Virtual Machine (optional) +[*] Install Apache Web Server +[*] Install PHP, MySQL, phpMyAdmin +[*] Fork the project on github to be able contribute +[*] Install the RED Matrix +[*] Debug the server via eclipse +[*] Contribute your changes via github +[/list] + +[h2]Install a Virtual Machine (optional)[/h2] + +[h3]Install KVM - Kernel-based Virtual Machine[/h3] + +[url=https://wiki.debian.org/KVM]Hier[/url] die Anleitung für Linux Debian. +Zusammenfassung der Anleitung (Schritt-für-Schritt für Linux): +[list=1] +[*] KVM installieren +[code]# sudo apt-get install qemu-kvm libvirt-bin[/code] +[*] Sich selbst zur Gruppe libvirt hinzufügen [code]# sudo adduser libvirt[/code] +[*] Grafische Oberfläche zur Verwaltung (Installation, Konfiguration,...) von virtuellen Maschinen installieren [code]# sudo apt-get install virt-manager[/code] +[*] Betriebssystem der Wahl herunterladen, das man halt später in der virtuelle Machine laufen lassen will zum Beispiel Linux Mint Debian oder debian ([url=http://ftp.nl.debian.org/debian/dists/wheezy/main/installer-amd64/current/images/netboot/mini.iso]mini.iso[/url]) +[*] Den Virt-Manager starten +- Neue virtuelle Maschine anlegen (Klick auf Icon) +- Als Installations-Medium das ISO-Image wählen, dass im Schritt vorher herunter geladen wurde, in unserem Fall Linux Mint Debian oder Lubuntu für ältere Rechner +- Optional: Virtuelle Maschine konfigurieren, genauer: Wieviel Hauptspeicher darf sie benutzen, wieviele CPUs,... +- Virtuelle Maschine starten.
