Centos7 安装go语言开发环境

1.安装

yum install  golang

2.配置环境变量

新建 go 目录作为项目目录

mkdir -p $HOME/go

用cat的方法在尾部增加配置配置golang的 GOROOT GOPATH

cat >>$HOME/.bash_profile<<EOF
export GOROOT=/usr/lib/golang
export GOPATH=\$HOME/golang
export PATH=\$PATH:\$GOROOT/bin
EOF

让配置生效

source $HOME/.bash_profile

3.检查下go的env环境变量

go env

输出

GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/root/golang"
