I don't know if I mentioned that I go on vacation to Girona (near Barcelona) soon and probably do not have WiFi wherever I go. I need a server with the following features:
Media Center to connect to the TV via HDMI/RGB.
Hotspot to connect remotely to the Pi from my iDevices (iPad, iPhone).
DLNA if I want to watch from my iPad some video through streaming.
Samba to download books or share from a HD.
To develop: Git, web server, MySQL and some other Framework.
I tell you my experience of how I've prepared a Raspberry Pi 2 using all the necessary software using as operating system DietPi. Everything in the next post.
Speaking of hardware, the least I'll need this holiday to mount my own decentralized server is:
Raspberry Pi 2 Model B
HD 1TB + USB powered HUB
Wireless USB device (rt3750)
What operating system can I use to install and configure all the software with little effort?. As I said, DietPi is the right choice because it consumes very little resources and just install what you need.
I have many stacked boards in my house. I opted for the Raspberry Pi 2 because I need maximum compatibility with the operating system.
Now the software I'll need (The full list of packages you can install it can be found at fuzon.co.uk):
LEMP: Nginx/(MySql)/PHP + Phpmyadmin
I'll skip the part of the image burned on a microSD and run the software installation because it's quite easy. Let's look at the possible incidents that I have found in each case when using different programs.
Well, this is a previous configuration more than anything to not have to authenticate in the system at each restart.
We create the file /firstname.lastname@example.org/autologin.conf and add:
[Service] ExecStart= ExecStart=-/sbin/agetty --autologin root --noclear %I 38400 linux
Now run systemctl enable email@example.com and when restart, you don't have to type any user and password. Cool!
When I want to see some multimedia content, simply write Kodi and, although it is the 15.2 version, it works perfectly. You can make boot directly from options dietpi-config > Autostart Options.
When you choose Exit from Kodi, the screen stays black. You must return to the first terminal typing ctrl+alt+F1
With Samba we'll not be able to play multimedia content with large size. To remotely view my tutorials/movies/tv shows I need DLNA support. MiniDLNA is the right choice and I have already used before, so it's just what I need.
We must copy the content we want to play in the folder that DietPi created in /mnt/dietpi_userdata (Videos, Pictures and Music). You can modify it in the file /etc/minidlna.conf. If the content you see on your device is outdated, you need to refresh the database server. Simply run the following:
minidlnad -R service minidlna restart
Nothing special. the user is root and password dietpi (is the same in almost all installed software). To access from my iDevices, I use the app File Hub or in the case of Android ES File Explorer. For multimedia files, my choice is VLC.
As bonus, I added at the end of the configuration file in Samba, which is located in /etc/samba/smb.conf, the following to access the folder where I store web developments:
[www] comment = www Share path = /var/www browseable = yes read only = no create mask = 0775 directory mask = 0775 valid users = root guest ok = yes writeable = yes public = yes
To activate the changes: systemctl stop samba-ad-dc.service && systemctl start samba-ad-dc.service
I've installed LEMP (Nginx, MySQL, PHP). If you go to the url of your RPI, you will see that you get a very basic version of a html document sited in /var/www/html.
To edit databases, I use phpmyadmin.

Well, with all this ready, I can go on vacation and maybe I have time to enjoy the beach, the sun, the pool and tapas like the rest of mortals... See you soon!.
