centos7下安装Go环境

cd /home
mkdir app
cd app
wget https://studygolang.com/dl/golang/go1.10.1.linux-amd64.tar.gz
wget https://dl.google.com/go/go1.14.2.linux-amd64.tar.gz
tar -xvf go1.10.1.linux-amd64.tar.gz

新建GOPATH目录

mkdir /home/work

配置环境变量

vim /etc/profile

export GOROOT=/home/app/go
export GOPATH=/home/work
export PATH=$PATH:$GOROOT/bin

使配置文件生效

source /etc/profile

查看配置是否生效

go version
go env

测试

cd /home/work
vi hello.go

package main
import "fmt"
func main() {
    fmt.Println("Hello, 世界")
}

go run hello.go
