How to Install Go on Ubuntu

What is Go?

Go is a compiled, statically typed programming language developed by Google. Many modern applications, including Docker, Kubernetes, and Caddy, are written in Go.

Install Go

  1. Use curl or wget to download the current binary for Go from the official download page. As of this writing, the current version is 1.9.3. Check the download page for updates, and replace 1.9.3 with the most recent stable version if necessary.

    curl -O https://storage.googleapis.com/golang/go1.9.3.linux-amd64.tar.gz
    
  2. Verify the .tar file using sha256sum:

    sha256sum go1.9.3.linux-amd64.tar.gz
    
      
    a4da5f4c07dfda8194c4621611aeb7ceaab98af0b38bfb29e1be2ebb04c3556c  go1.9.3.linux-amd64.tar.gz
    
    
  3. Extract the tarball:

    tar -xvf go1.9.3.linux-amd64.tar.gz
    
  4. Adjust the permissions and move the go directory to /usr/local:

    sudo chown -R root:root ./go
    sudo mv go /usr/local
    

Adjust the Path Variable

  1. Using a text editor, open the ~/.profile file and add the following two lines to the bottom of the file:

    ~/.profile
    1
    2
    
    export GOPATH=$HOME/go
    export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin
  2. Save the file, and load the commands into the current shell instance:

    source ~/.profile
    

Test the Installation

According to the official documentation, the following steps are the recommended way to test the success of the installation:

  1. In your home directory create a folder named go, this will be your workspace:

    mkdir go
    
  2. Within that directory create /src/hello and within that directory copy and paste the contents of the file below:

    mkdir -p go/src/hello && cd go/src/hello
    touch hello.go
    
    hello.go
    1
    2
    3
    4
    5
    6
    7
    
    package main
    
    import "fmt"
    
    func main() {
        fmt.Printf("hello, world\n")
    }
  3. Build the hello.go file:

    go build
    
  4. Run the script:

    ./hello
    
      
    hello, world
