1.下载golang安装包

wget https://dl.google.com/go/go1.12.5.linux-amd64.tar.gz

2.解压至/usr/local文件夹

tar -C /usr/local -xzf go1.12.5.linux-amd64.tar.gz

2.配置环境变量vim /etc/profile

export GOROOT=/usr/local/go #设置为go安装的路径
export GOPATH=$HOME/go #默认安装包的路径
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

source /etc/profile使修改生效.

3.测试结果
