linux下搭建go环境很简单：

1.下载go1.2.1.linux-386.tar.gz，网上到处有类似包，并放到linux目录下。

taogeqq@taogeqq-virtual-machine:~/myspace$ ls
a.out go1.2.1.linux-386.tar.gz test.cpp test.go
taogeqq@taogeqq-virtual-machine:~/myspace$ 

2.  切换到root用户，在root下解压，解压即安装，多么绿色的软件啊：

root@taogeqq-virtual-machine:/home/taogeqq/myspace# tar zxvf go1.2.1.linux-386.tar.gz -C /usr/local/

可以看到， 在目录下多了go目录：

root@taogeqq-virtual-machine:/home/taogeqq/myspace# ls /usr/local
bin etc games go include lib man sbin share src
root@taogeqq-virtual-machine:/home/taogeqq/myspace# 

此时，就安装了go环境，现在可以退出root用户了

3.  写一个test.go文件， 并测试：

taogeqq@taogeqq-virtual-machine:~/myspace$ ls
a.out go1.2.1.linux-386.tar.gz test.cpp test.go
taogeqq@taogeqq-virtual-machine:~/myspace$ 
taogeqq@taogeqq-virtual-machine:~/myspace$ cat test.go
package main
import "fmt"
func main(){
  fmt.Println("hello world")
  fmt.Println("This is my first Go code")
}
taogeqq@taogeqq-virtual-machine:~/myspace$ 
taogeqq@taogeqq-virtual-machine:~/myspace$ /usr/local/go/bin/go run test.go
hello world
This is my first Go code
taogeqq@taogeqq-virtual-machine:~/myspace$ 

获取到了预期的结果。

有个问题， 我们执行go run test.go试下：

taogeqq@taogeqq-virtual-machine:~/myspace$ go run test.go
程序“go”尚未安装。 您可以使用以下命令安装：
sudo apt-get install golang-go
taogeqq@taogeqq-virtual-machine:~/myspace$ 

可见， 可以用sudo apt-get install golang-go一件安装， 我们之前也说过apt-get的强大。

既然我们已经安装了， 那先可以忽略sudo apt-get install golang-go，  那要执行go run test.go， 怎么办呢？ 很简单， 把这个路径加到PATH中就OK了， 如下：

taogeqq@taogeqq-virtual-machine:~/myspace$ echo $PATH           
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
taogeqq@taogeqq-virtual-machine:~/myspace$ 
taogeqq@taogeqq-virtual-machine:~/myspace$ vim /home/taogeqq/.bash_profile
taogeqq@taogeqq-virtual-machine:~/myspace$ 
taogeqq@taogeqq-virtual-machine:~/myspace$ cat /home/taogeqq/.bash_profile
export PATH=$PATH:/usr/local/go/bin/
taogeqq@taogeqq-virtual-machine:~/myspace$ 
taogeqq@taogeqq-virtual-machine:~/myspace$ source /home/taogeqq/.bash_profile
taogeqq@taogeqq-virtual-machine:~/myspace$ 
taogeqq@taogeqq-virtual-machine:~/myspace$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/go/bin/
taogeqq@taogeqq-virtual-machine:~/myspace$ 
taogeqq@taogeqq-virtual-machine:~/myspace$ go run test.go
hello world
This is my first Go code
taogeqq@taogeqq-virtual-machine:~/myspace$ 

其中/home/taogeqq是taogeqq的主目录。

linux下玩东西就是爽，NM的Windows注册表，我真是烦透了。
