## move binary and add to path
mv go /usr/local

## create the goApps directory, set GOPATH, and put it on PATH
mkdir goApps
echo "export GOPATH=/root/goApps" >> ~/.profile

source ~/.profile

## get the code and move into repo
REPO=github.com/cosmos/cosmos-sdk
go get $REPO
cd $GOPATH/src/$REPO

## build
git checkout master
make get_tools

make install

You can squash line 11 and 14 into one command:

tar -xvf go1.10.linux-amd64.tar.gz -C /usr/local

Same as line 31,32,33:

make get_tools get_vendor_deps install
