Windows上编译可运行在Linux上的go二进制文件
1、前言
默认Windows上编译的go二进制为exe,只能运行在Windows上,而想要在Linux上运行,则需要到Linux的平台编译。有没有一种办法可以直接在Windows上编译,然后直接拿到Linux就可以运行呢?这几天就看到一个文章,就是做的这个事情,也比较简单,但很有用,记录一下。
实现功能:Windows上编译go,部署到Linux运行

2、步骤
打开cmd,运行以下命令(设置为Linux平台,应该是这么理解,然后是设置为amd64架构)
SET GOOS=linux
SET GOARCH=amd64
然后正常编译即可
go build -o xxx xxx.go
3、例子
go代码
package main
import (
"fmt"
"golang.org/x/crypto/ssh"
"net"
"os"
"os/exec"
"time"
)
func hostKeyCallback(hostname string, remote net.Addr, key ssh.PublicKey)error {
fmt.Println(fmt.Sprintf("hostname:%s",hostname))
fmt.Println(fmt.Sprintf("remote:%+v",remote))
fmt.Println(fmt.Sprintf("key:%+v",key))
return nil
}
func main(){
const DefaultPathPerm = 0744
path:="/etc/node-exporter"
err := os.MkdirAll(path, DefaultPathPerm)
if err != nil {
fmt.Println(fmt.Sprintf("创建目录失败, 目录:%s, err:%s",path,err.Error()))
return
}
cmsStr :="yum install -y wget tar"
cmd:=exec.Command("yum","install","-y","wget","tar")
combinedOutput, err := cmd.CombinedOutput()
if err != nil {
fmt.Println(fmt.Sprintf("执行命令失败, 命令:'%s', err:%s", cmsStr,err.Error()))
return
}
fmt.Println(fmt.Sprintf("执行命令成功,命令:'%s', 输出:%s", cmsStr,combinedOutput))
user:="root"
passwd:="123456"
addr:="192.168.108.216:22"
auth := make([]ssh.AuthMethod, 0)
auth = append(auth, ssh.Password(passwd))
clientConfig := ssh.ClientConfig{
Config: ssh.Config{},
User: user,
Auth: auth,
HostKeyCallback: hostKeyCallback,
BannerCallback: nil,
ClientVersion: "",
HostKeyAlgorithms: nil,
Timeout: 30*time.Second,
}
client, err := ssh.Dial("tcp",addr,&clientConfig)
if err != nil {
fmt.Println(fmt.Sprintf("SSH连接Linux失败, addr:%s, err:%s",addr,err))
return
}
fmt.Println(fmt.Sprintf("SSH连接Linux成功, addr:%s",addr))
defer func(client *ssh.Client) {
err := client.Close()
if err != nil {
fmt.Println(fmt.Sprintf("关闭SSH失败:%s, err:%s",addr,err))
}
fmt.Println(fmt.Sprintf("关闭SSH成功:%s, err:%s",addr,err))
}(client)
}
编译
拷贝到Linux运行
