下载

wget https://dl.google.com/go/go1.13.linux-amd64.tar.gz

解压压缩包到/usr/local目录

tar -C /usr/local -xzf go1.13.linux-amd64.tar.gz

将/usr/local/go/bin 目录添加至PATH环境变量

export PATH=$PATH:/usr/local/go/bin

重新读取环境变量

source /etc/profile

查看版本

go version

设置GOPATH

1. 全局设置

2. 用户级别设置

 vi ~/.bash_profile

在文件的结尾加上

export GOPATH=/usr/local/src/go_path

使配置马上生效

source /etc/profile

3. 临时生效
   直接在命令行添加

 export GOPATH=/usr/local/src/go_path
