How to Install Go 1.9 on Ubuntu

👇

Step 1 – Install Go Language

Login to your Ubuntu system using ssh and upgrade to apply latest security updates there.

$ sudo apt-get update

$ sudo apt-get -y upgrade 

Now download the Go language binary archive file using following link.

$ wget https://dl.google.com/go/go1.9.4.linux-amd64.tar.gz

Now extract the downloaded archive and install it to the desired location on the system. 

Then I am installing it under /usr/local directory. You can also put this under the home directory (for shared hosting) or other location.

$ sudo tar -xvf go1.9.4.linux-amd64.tar.gz

$ sudo mv go /usr/local

Step 2 – Setup Go Environment

Now you need to setup Go language environment variables for your project. Commonly you need to set 3 environment variables as GOROOT, GOPATH and PATH.

GOROOT is the location where Go package is installed on your system.

$ export GOROOT=/usr/local/go

GOPATH is the location of your work directory. For example my project directory is ~/go_project/.

$ export GOPATH=$HOME/go_project/

Now set the PATH variable to access go binary system wide.

$ export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

All above environment will be set for your current session only. To make it permanent add above commands in ~/.profile file.

Step 3 – Verify Installation

At this step, you have successfully installed and configured go language on your system. First, use the following command to check Go version.

$ go version

Output : go version go1.9.4 linux/amd64

Now also verify all configured environment variables using following command.

$ go env

Output : 


GOARCH="amd64"

GOBIN=""

GOEXE=""

GOHOSTARCH="amd64"

GOHOSTOS="linux"

GOOS="linux"

GOPATH="/root/Projects/Proj1"

GORACE=""

GOROOT="/usr/local/go"

GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64"

GCCGO="gccgo"

CC="gcc"

GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build764105058=/tmp/go-build -gno-record-gcc-switches"

CXX="g++"

CGO_ENABLED="1"

CGO_CFLAGS="-g -O2"

CGO_CPPFLAGS=""

CGO_CXXFLAGS="-g -O2"

CGO_FFLAGS="-g -O2"

CGO_LDFLAGS="-g -O2"

PKG_CONFIG="pkg-config"

Step 4 – Config Source Path Set 

Now you set go env path in source file.

 

$ sudo vi ~/.profile

Inside that file, you will Set the Go variable path. Inside of line

# ~/.profile: executed by the command interpreter for login shells.

# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login

# exists.

# see /usr/share/doc/bash/examples/startup-files for examples.

# the files are located in the bash-doc package.



# the default umask is set in /etc/profile; for setting the umask

# for ssh logins, install and configure the libpam-umask package.

#umask 022



# if running bash

if [ -n "$BASH_VERSION" ]; then

    # include .bashrc if it exists

    if [ -f "$HOME/.bashrc" ]; then

 . "$HOME/.bashrc"

    fi

fi



# set PATH so it includes user's private bin if it exists

if [ -d "$HOME/bin" ] ; then

    PATH="$HOME/bin:$PATH"

fi



export GOPATH="$HOME/go_project"

export GOBIN="$GOPATH/bin"

export PATH="$PATH:/usr/local/go/bin"

export GOROOT="/usr/local/go"
