linux下搭建go环境很easy

        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。 我是从CSDN上下载的, 然后传到linux机器上: 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 {MOD}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。
