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 -xvf 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

5.生效环境变量

source /etc/profile

然后执行go
