1,官网:
https://golang.google.cn/

2，下载页面:

https://golang.google.cn/dl/

我们选择linux版本下载，复制地址

3,用wget下载到本地:

​root@lhdpcg:~# mkdir /usr/local/source
root@lhdpcg:~# mkdir /usr/local/soft
root@lhdpcg:~# cd /usr/local/source
root@lhdpcg:/usr/local/source# mkdir go
root@lhdpcg:/usr/local/source# cd go
root@lhdpcg:/usr/local/source/go# wget https://go.dev/dl/go1.17.6.linux-amd64.tar.gz

1,解压:

root@lhdpcg:/usr/local/source/go# tar -zxvf go1.17.6.linux-amd64.tar.gz

2,移动到安装目录下

root@lhdpcg:/usr/local/source/go# mv go/ /usr/local/soft/

1，编辑profile

root@lhdpcg:/usr/local/source/go# vim /etc/profile

添加两行:

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

2,使profile生效

root@lhdpcg:/usr/local/source/go# source /etc/profile

3,查看go的版本

root@lhdpcg:/usr/local/source/go# go version
go version go1.17.6 linux/amd64

root@lhdpcg:~# mkdir /data/
root@lhdpcg:~# mkdir /data/goapp
root@lhdpcg:~# mkdir /data/goapp/hello
root@lhdpcg:~# cd /data/goapp/hello
root@lhdpcg:/data/goapp/hello# vim hello.go

代码:

package main

import "fmt"

func main() {
    fmt.Printf("hello, worldn")
}

运行:

root@lhdpcg:/data/goapp/hello# go mod init hello
go: creating new go.mod: module hello
go: to add module requirements and sums:
        go mod tidy
root@lhdpcg:/data/goapp/hello# go build
root@lhdpcg:/data/goapp/hello# ./hello
hello, world

​root@lhdpcg:/data/goapp/hello# more /etc/os-release
