sia-rpi4
Here you can find instructions how to run siad and siac on a raspberry pi 4. This is a first version and will (hopefuly) be udpated. If there are problems or you want to contribute, just open an issue or a merge request.
Install and boot an official raspberian image (32bit) and follow the instructions of sakaki-/bcm2711-kernel-bis. You only have to run the wget and sync command and add some lines to the config.txt. This will install an 64 bit kernel on the 32 bit userspace. Be aware that this installation but yourself at a risk as mentionen on the bottom of sakaki-/bcm2711-kernel-bis readme file.
install golang
sudo apt-get install golang
set GOARCH to arm64 (cross compile since userspace is 32bit)
echo "export GOARCH=arm64
export GOOS=linux" >> ~/.bashrc
bash #to start new bash with the new variables
self compile siacoin binaries (siac siad via https://gitlab.com/NebulousLabs/Sia) with
git clone https://gitlab.com/NebulousLabs/Sia siasrc
cd siasrc && make
The new binaries can be found under "~/go/bin/linux_arm64/", but we just add them to the path as follows.
Add siad siac to PATH so we can run it anywhere in the console
echo 'PATH=~/go/bin/linux_arm64:$PATH' >> ~/.profile
sudo reboot
Update siac siad binaries
If there is a new version or you want to pull the latest changes of sia run
cd siasrc && git pull && make
With this command the new changes will be pulled from gitlab and compiled into the "~/go/bin/linux_arm64/" folder which is already included in the path and the new binaries should be used automatically, just restard siad.
Set bandwidth limits
We use trickle to limit the throughput only for the process
sudo apt-get install trickle
we let trickle start siad to do its limiting, units are in KB/s
mkdir sia
cd sia #first change the directory to the folder where sia will store its data
trickle -s -d 50000 -u 30000 siad -M gctwr
This will launch siad without the host and using only the renter.
Notes
You will have to set up some swap if you are going to download/upload larger files. This is out of the scope of this doc. See this doc as a proof of concept and do not use this in production enviroment.
