Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. Go supports the following systems:

• Linux
• FreeBSD
• Mac OS X (also known as Darwin)
• Windows

Download installation package is: https://golang.org/dl/.

Each system corresponding to the package name:

UNIX / Linux / Mac OS X, and FreeBSD installation

The following describes the use of the source code in the UNIX / Linux / Mac OS X, and FreeBSD system installation method:

1. Download Source Package: go1.4.linux-amd64.tar.gz.

2, unzip the downloaded source package to /usr/ local directory.

tar -C /usr/ local -xzf go1.4.linux-amd64.tar.gz

3, add /usr/ local / go / bin directory to the PATH environment variable:

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

Note: You can use the MAC system .pkg the end of the installation package by double-clicking to complete the installation, the installation directory /usr/local/go/down.

Windows system installation

Under Windows you can use .msi suffix (download list can be found in the file, such as go1.4.2.windows-amd64.msi) installation package to install.

By default, the .msi files will be installed in the c: \ directory Go. You can c: \ Go \ bin directory to the PATH environment variable. After adding a command window you need to restart to take effect.

installation testing

Create a working directory C: > Go_WorkSpace.

File name: test.go, code is as follows:

    package main
    
    import "fmt"
    
    func main () {
       fmt.Println ( "Hello, World!")
    }

Using the go command code above output results are as follows:

    C:\Go_WorkSpace> go run test.go
    
    Hello, World!
