Linux(centos redhat ) 安装
1.访问官方地址：
https://golang.org/dl/ ##由于相关ZC你懂的，最好能翻墙下
2.下载64位绿色包：
https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz
3.下载完毕后：
假定你想要安装Go的目录为 $GO_INSTALL_DIR，后面替换为相应的目录路径。
解压缩tar.gz包到安装目录下：tar zxvf go1.8.3.linux-amd64.tar.gz -C $GO_INSTALL_DIR。
4.添加环境变量vim /etc/profile,加入如下几行
export PATH=$PATH:$GO_INSTALL_DIR/go/bin
export GOROOT= $GO_INSTALL_DIR/go
export GOBIN=$GOROOT/bin
export GOPATH= $GO_INSTALL_DIR/go/data ##注意 $GO_INSTALL_DIR 为你的go的安装或者解压目录
然后执行go
