CentOS7安装Golang

打开https://golang.google.cn/dl/

解压下载好的包

tar -zxvf go1.13.3.linux-amd64.tar.gz

移动解压好的目录到/usr/local/下

mv go /usr/local/go

新建GOPATH目录

mkdir /opt/go

设置环境变量

vim /etc/profile

在末尾添加

export GOROOT=/usr/local/go
export GOBIN=$GOPATH/bin   //一般设置GOPATH下的bin,意思为第三方包编译的可执行文件路径
export PATH=$PATH:/usr/local/go/bin
export PATH=$PATH:/opt/go/bin
export GOPATH=/opt/go
export GO111MODULE=on
export GOPROXY=https://goproxy.cn

保存并退出:wq
使其生效

source /etc/profile

验证安装是否成功
