export GOROOT
export GOPATH

PATH=$PATH:/opt/go/bin

Who is doing this un professional things on our production server….
>type go
go is aliased to `git checkout'
>unalias go

Unzip and place that in working directory

Prepare the directory
>sudo ln -s /home/carl/work /opt/work
>mkdir /opt/work/go/bin

Add these in the PATH
PATH="/opt/go/bin:$PATH"
export GOROOT="/opt/go"
export GOPATH="/opt/work/go"

Check go version
