Ubuntu Install Go language Run environment _golang

On the Ubuntu forum, I saw a post that grabbed the image data in the Web page, so I tried it with the go language. So let's install a running environment first. The following installation methods are installed successfully on 32-bit and 64-bit ubuntu12.04, and all commands, programs I have actually run, if there is a problem, please leave a message to me.

1. Installation Mercurial

Mercurial is a version control system that will use this tool to download the Go language source. In Ubuntu under the Apt-get installed on the OK, very convenient.

Copy Code code as follows:

sudo apt-get install mercurial

2, download the Go language source

This step creates a new Go folder at the command line's current directory and downloads the code file to the went folder, so make sure there is no Go folder under the current directory. For example, I am operating directly in the/home directory.

Copy Code code as follows:

HG Clone-u Release Https://code.google.com/p/go

3. Start Installation

Copy Code code as follows:

CD GO/SRC
./all.bash

This process takes some time, one-click installation, very powerful. When installed, you will be prompted with information similar to the following.

Copy Code code as follows:

Installed go to linux/386 in/home/go
Installed Commands In/home/go/bin
You are need to Add/home/go/bin to your PATH.

Probably say to go to the bin directory set to $path, this variable is to run the command search path, temporarily do not set it does not matter, you can use the full path to deal with. Since I previously chose the/home directory, the Go Bin directory is/home/go/bin after the installation is complete

4, international practice, the first program Hello world!

Copy Code code as follows:

Package Main
Import "FMT"
Func Main () {
Fmt. Printf ("Hello, world\n")
}

Save as a hello.go file, and then execute

Copy Code code as follows:

/home/go/bin/go Run Hello.go

See Output Hello World Description The environment was installed successfully.
