Introduction: DLNA Media Server
Keep all your media in one place and easily accessible.
4K streaming works just fine ( disk io: ~10MB/s, network: ~3MB/s)
Step 1: What You Need
1. A orange pi one board (but you can use any other)
2. Micro SD card (>=4GB)
3. An external HDD
4. A box - an old hp power source
5. Hobby-color plate that resists to at least 75 C
6. An usb port recovered from an old computer
7. Banana connectors, cables, bolts recovered from old computer's serial or vga port
Step 2: The Fun Part
- Cut the hobby-color plate for the bottom, make some holes for the pi to fit in.
- Cut the front to match the power supply face and the pi lan and usb port(s) - there were 2 fans on that side separated by a small iron sheet (which I've cut) and reuse the fan holes to assemble it.
- For this specific board (orange pi one) there are 2 additional data ports (https://forum.armbian.com/topic/755-orange-pi-one-adding-usb-analog-audio-out-tv-out-mic-and-ir-receiver/).
- I've been very lucky to soldier two cables on pins 3 and 4 (first easily scratch the pins); to be sure that those cables do not come off, use a glue gun to fix it on the boar - obviously after testing. For the other pi's I would solder the cables on the back of the plate directly on the usb port's pins.
- Solder 2 cables on each banana plug (I used an old cd-rom audio cable).
- Connect the power cables to the pi, this model supports it on the gpio pins 4 (+5V) and 6 (ground) - the pins are on the internal row on the opposite side of the lan port.
- Connect the other power cables to the usb port, and the data cables to pins 3 and 4 of the usb port.
- Add the hard drive and mount the screws.
Step 3: The Soft Part
- I use armbian (https://www.armbian.com/download/) as it is much easier to install minidlna afterwards.
- Setup the network - static ip:
allow-hotplug eth0 no-auto-down eth0 iface eth0 inet static address <your desired ip> netmask <your netmask> (usually 255.255.255.0) gateway <your gateway> dns-nameservers <your dns server>
- Setup the drive - I would format it as EXT4 (beware of the existing data !!!):
fdisk /dev/sda (p - to see partition layout, d - delete all if it's the case, n - create a new one, w - write changes) you may want to reboot so the kernel sees it (or if partprobe does not work) mkfs.ext4 -L dlna-disk /dev/sda1
- Use automount instead of fstab - to avoid un-bootable system in case mount fails
apt-get install autofs in /etc/auto.master append /- /etc/auto.ext-usb in /etc/auto.ext-usb /srv -fstype=ext4 :/dev/disk/by-label/dlna-disk service autofs start && systemctl enable autofs.service
- Install and configure minidlna
apt-get install minidlna /etc/minidlna.conf media_dir=/srv service minidlna start && systemctl enable minidlna.service
- Increase the number of inotify watchers
/etc/sysctl.conf fs.inotify.max_user_watches=1048576 sysctl -p
- Punch a hole in your firewall
apt-get install firewalld service firewalld start && systemctl enable firewalld.service firewall-cmd --permanent --add-port 8200/tcp firewall-cmd --permanent --add-port 1900/udp firewall-cmd --reload
- Decrease RAM frequency to keep it cool and save power
h3consumption -d 408 reboot
Step 4: Add Some Data
- Use filezilla to connect to the sftp service and copy your data under /srv
- Install samba to access it
apt-get install samba # add this to the end of /etc/samba/smb.conf [dlna-media] comment = My Media path = /srv browseable = yes writable = yes valid users = minidlna # make a samba user smbpasswd -a minidlna # activate the service service smbd start && systemctl enable smbd.service # let it through the firewall firewall-cmd --permanent --add-service samba firewall-cmd --reload # grant full access for the minidlna user apt-get install acl setfacl -R -m u:minidlna:rwx -m d:u:minidlna:rwx /srv
We have a be nice policy.
Please be positive and constructive.
