Golang安装和环境配置 Golang安装和环境配置

安装golang：下载安装包，国内地址：https://golang.google.cn/dl/

$ sudo tar -C /usr/local -xzf go1.12.5.linux-amd64.tar.gz//解压

添加环境变量，修改/etc/profile 或$HOME/.profile或/etc/profile.d/目录的文件

$ sudo vi /etc/profile.d/brianconfig.sh//添加以下内容 export GOROOT=/usr/local/go //定义GOROOT export PATH=$PATH:/usr/local/go/bin // 添加go/bin到系统环境变量PATH中 export GOPATH=/work/wks_golang //添加GOPATH变量

查看golang版本：

$ go version go version go1.12.5 linux/amd64

查看GOROOT

$ go env GOROOT /usr/local/go

查看GOPATH

$ echo $GOPATH / /work/wks_golang

demo测试在/work/wks_golang目录内，新建 src/hello, 创建hello.go:

package main import "fmt" func main() { fmt.Printf("hello, world\n") }

使用go tool构建:

$ cd ./src/hello $ go build

The command above will build an executable named hello in the directory alongside your source code. Execute it to see the greeting:
$ ./hello
hello, world
