Assuming you’ve logged in as root in Debian 5.0, to install the Go programming language by Google,

1. Add these environmental variables for Go in .bash_profile:

   export GOROOT=$HOME/go
   export GOARCH=386  # for 32 bit architectures. Use GOARCH=amd64 for 64 bit architectures
   export GOOS=linux
   export GOBIN=$HOME/bin
   PATH=$PATH:$GOBIN
   

2. Install the Mercurial ‘hg’ command:

   aptitude install mercurial

3. Fetch the sources of Go and put them at $GOROOT:

   hg clone -r release https://go.googlecode.com/hg/ $GOROOT

4. Fetch compilers and related utilities:

   aptitude install bison gcc libc6-dev ed make

5. Create the directory $HOME/bin by:

   mkdir $HOME/bin

   and compile Go:

   cd $GOROOT/src
   make all

Done. You can now go about writing your first hello world program. If you haven’t got a server yet, I recommend Linode VPS and Rackspace Cloud.
