整理了一下，网上关于golang的安装有三种方式（注明一下，我的环境为CentOS-6.x, 64bit）

方式一：yum安装（最简单）

rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpmyum install golang

方式二：源码安装：

wget http://go.googlecode.com/files/go1.2.linux-amd64.tar.gztar -xvf go1.2.linux-amd64.tar.gzsudo cp -r go /usr/local/govi /etc/profileexport GOROOT=/usr/local/goexport PATH=$PATH:$GOROOT/binsource /etc/profile

方式三：类似源码安装

$ sudo yum install mercurial$ hg clone -u release https://go.googlecode.com/hg/ golangTo build the Go distribution, runcd go/src./all.bashIf all goes well, it will finish by printing output like:ALL TESTS PASSED---Installed Go for linux/amd64 in /home/you/go.Installed commands in /home/you/go/bin.*** You need to add /home/you/go/bin to your $PATH. ***

安装完毕之后看看状态：

$go versiongo version go1.2 linux/amd64

测试文件

vim hello.go

package mainimport "fmt"func main() {        fmt.Printf("hello go\n")}

运行：

go run hello.gohello go
