Node-Red on Unbuntu 20.04 (64 bit)

Mick W8BE

I am working on migrating my node red flows to unbuntu 20.04 server edition in order to take advantage of the 64 bit OS. I wanted to pass on info on what I had to do to get dot net and FRStack to load...

Here is what I had to load to get dotnet / FRStack up and running:

I downloaded the following file and ftp'd over to my Pi.

dotnet-sdk-3.1.109-linux-arm64.tar

Then follow Mark's directions:

sudo mkdir -p /opt/dotnet

sudo tar zxf dotnet-sdk-3.1.109-linux-arm64.tar.gz -C /opt/dotnet

sudo ln -s /opt/dotnet/dotnet /usr/bin

I just got it up and see the process:

/usr/bin/dotnet FRStackWebApi.dll --urls http://*:5025

I have to still enable the flows and test it out. Hoping that I am past the hard part.

Here is what I have noticed on 64 OS vs 32 bit OS. on the 32 bit OS, memory load is stingy. Using a 2Gb Pi I run about 25% of available ram. On the 64 bit it pretty much doubles the memory load. However the the cpu ticks are reduced. I never thought about that in those terms before. I guess it makes sense.

I will report back probably tomorrow to advise if the flows work as advertised.

Ok so I could not wait...Had to try it out....and...it works....

As you can see cpu ticks are low but ram usage is up...
