下载和解压 Golang

先去获取 Golang 的下载链接

https://go.dev/dl/
因为我是 64 位的系统，所以选 linux amd64，目前（2022.03.12）最新版链接如下
https://go.dev/dl/go1.17.8.linux-amd64.tar.gz

安装 aria2c

# apt install aria2c

下载 Golang

# aria2c -x 8 https://go.dev/dl/go1.17.8.linux-amd64.tar.gz

解压安装包

# tar -zxvf go1.17.8.linux-amd64.tar.gz -C /usr/local/

配置环境变量

现在要配置环境变量让PATH包含 Golang 的路径（/usr/local/go/bin）。
如果你想给所有用户配置，使用这个

# echo "export PATH=/usr/local/go/bin:\${PATH}" | sudo tee /etc/profile.d/go.sh

# source /etc/profile.d/go.sh

如果仅仅想给当前用户配置，选这个

# echo "export PATH=/usr/local/go/bin:\${PATH}" | sudo tee -a $HOME/.profile

# source $HOME/.profile

验证 Go 安装

运行 Go 版本获取

# go version
go version go1.17.8 linux/amd64
