GO Lang Installation

This is a creation in Article, where the information may have evolved or changed.

Installation

To build Go 1.x (x≥5), you need to first install Go 1.4 $GOROOT_BOOTSTRAP . The default $GOROOT_BOOTSTRAP is $HOME/go1.4 . We use Go 1.4 as the base version of the boot to compile the toolchain.
Install go1.4 First, then install go1.6.2 or other versions.

Preset go1.4

Download go1.4.linux-amd64.tar.gz or other correspondence package, this is already compiled well, larger, directly there is a bin file available
Unzip the package, modify the directory name go->go1.4
Move to $HOME/ next, there will be a path after the installation is complete /root/go1.4/bin

Install new version

Add the environment variable, ~/.BASHRC, and add the following variable:

export GOROOT=$HOME/goexport PATH=$GOROOT/bin:$PATH

Run environment variables:

source ~/.bashrc

$HOMEPath is /root
Installing the Go tool chain

sudo apt-get install bison ed gawk gcc libc6-dev make git

Installing mercurial

sudo apt-get install mercurial

Download go source extract to the $GOROOT directory
I downloaded it from here, and I can get it from other places.
