安装GO工具

[root@devlop package]# wget https://studygolang.com/dl/golang/go1.12.7.linux-amd64.tar.gz

[root@devlop package]# tar -zxvf go1.12.7.linux-amd64.tar.gz -C /usr/local/

[root@devlop package]# cd /usr/local/go/

[root@devlop go]# ls

api  AUTHORS  bin  CONTRIBUTING.md  CONTRIBUTORS  doc  favicon.ico  lib  LICENSE  misc  PATENTS  pkg  README.md  robots.txt  src  test  VERSION

为GO设置全局环境变量。

[root@devlop go]# vim /etc/profile

export PATH=$PATH:/usr/local/go/bin

[root@devlop go]# source /etc/profile

[root@devlop ~]# go version

go version go1.12.7 linux/amd64

新建test项目测试

[root@devlop ~]# mkdir test

[root@devlop ~]# vim test/test.go

package main

import "fmt"
func main() {
    fmt.Println("Welcome  Golang")
}

保存退出并编译test.go文件

[root@devlop ~]# cd test/
[root@devlop test]# go build test.go

编译后会在项目文件夹下生成test可执行文件，并运行该文件

两种方式任选其一：

好了到这里我们我安装结束了。欢迎一起学习Golang ! ! !
