Go

We use Go for Lightning LND implementation and for monitoring services.

Build Go

1. Fetch bootstrap go (as root)

sudo apt install -y golang git

--- after this commands should be run under the unix account where Go related services will be running. ---

for example login as Lighting user like this:

sudo su -l lightning

2. Set bootstrap path and gopath. Run:

echo 'export GOROOT_BOOTSTRAP="$(ls -1d /usr/lib/go-* | tail -n1)"' >> ~/.profile
echo 'export GOROOT=~/src/go' >> ~/.profile
echo 'export GOPATH=~/gocode' >> ~/.profile
echo 'export PATH=$GOROOT/bin:$GOPATH/bin:$PATH' >> ~/.profile

Load ~/.profile

. ~/.profile

4. Fetch new go

git clone https://go.googlesource.com/go ~/src/go
cd ~/src/go
git fetch

git checkout $(git tag | grep go1.19.[0-9]*$ | sort -V | tail -n1) # checkout latest minor version

5. Build new go

. ~/.profile
cd $GOROOT/src
./make.bash

At the end it should say "Installed commands in $GOROOT/bin"
