1、下载源码包：go1.4.linux-amd64.tar.gz。
2、将下载的源码包解压至 /usr/local目录。
tar -C /usr/local -xzf go1.4.linux-amd64.tar.gz
3、配置GOPATH、GOROOT环境变量：
vi /etc/profile添加以下几行在文件末尾
export GOROOT=/usr/local/go
export GOPATH=/home/www/go
export PATH=$PATH:$GOROOT/bin
保存退出
source /etc/profile立即生效
这个时候输入以下命令就能看到安装配置完成
[root@10-23-67-69 bin]# go version
go version go1.11 linux/amd64
[root@10-23-67-69 bin]# go help
