源码安装Golang

• 下载Golang 源码
  wget https://studygolang.com/dl/golang/go1.14.1.linux-amd64.tar.gz

• 解压源码到/usr/local目录
  tar -C /usr/local -xzf go1.14.1.linux-amd64.tar.gz

• 配置Golang环境变量
  在配置文件/etc/profile最后加入

• 设置Golang下载代理
  go env -w GOPROXY=https://goproxy.cn,direct

export GOROOT=/usr/local/go # 设置为go安装的路径
export GOPATH=/root/code/go # go get下载的东西都会放到这里
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

是配置文件生效source /etc/profile

• 查看go env环境变量
