jenkins系列-05-jenkins构建golang程序

下载go1.20.2.linux-arm64.tar.gz 并存放到jenkins home目录：

写一个golang demo程序：静态文件服务器：https://gitee.com/jelex/jenkins_golang

package main

import (
	"encoding/base64"
	"flag"
	"fmt"
	"log"
	"net/http"
	"strings"
)

const (
	uw = "username用户名:你想要设置的密码"
)

type authFileSrvHandler struct {
	http.Handler
}

func (f *authFileSrvHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {

	auth := r.Header.Get("Authorization")
	log.Println("got req:auth", auth)
	if auth == "" {
		w.Header().Set("WWW-Authenticate", `Basic realm="您必须输入用户名和密码"`)
		w.WriteHeader(http.StatusUnauthorized)
		return
	}
	log.Println("auth->", auth)
	split := strings.Split(auth, " ")
	if len(split) == 2 && split[0] == "Basic" {
		bytes, err := base64.StdEncoding.DecodeString(split[1])
		if err == nil && string(bytes) == uw {
			f.Handler.ServeHTTP(w, r)
			return
		}
	}
	w.Write([]byte("请联系相关人员获取用户名和密码！"))
}

/*

	通过这种方式修改文件服务器的根路径及端口

jelex@jelexxudeMacBook-Pro static-file-server % go run .\main.go -p 8888

	8888

exit status 2
jelex@jelexxudeMacBook-Pro static-file-server % go run .\main.go -r <absolute path>
jelex@jelexxudeMacBook-Pro static-file-server % go run main.go -r ~
*/
func main() {

	var rootPath, port string

	flag.StringVar(&rootPath, "r", "", "文件根目录")
	flag.StringVar(&port, "p", "6000", "文件服务器端口")

	flag.Parse()

	mux := http.NewServeMux()

	fs := http.FileServer(http.Dir(rootPath))

	mux.Handle("/", &authFileSrvHandler{fs})

	fmt.Println(rootPath, port)

	http.ListenAndServe(":"+port, mux)
}

bin/build.sh

#局部变量(执行文件名称), 根据自己项目写
project_name="file-srv"
#杀掉之前正在运行的程序
go_id=`ps -ef|grep "./${project_name}" |grep -v "grep" | awk '{print $2}'`
if [ -z "$go_id" ];
then
    echo "[go pid not found]"
else
	#杀掉进程
    kill -9 $go_id
    echo "killed $go_id"
fi

echo "clean old file"
rm -rf ${project_name}
#执行日志，根据自己项目情况可选
rm -rf ${project_name}.log

if [ -f main ]; then
    echo "start new process"
    mv main ${project_name}
    chmod -R 777 ${project_name}
    #这里要防止nohup不执行，添加了一个BUILD_ID, -r ~ 表示程序运行的参数（根目录为~ home目录）
    BUILD_ID=DONTKILLME nohup ./${project_name} -r ~ >${project_name}.log 2>&1 &
else
echo "executable file not found,quit"
fi

新配置一个服务器：事先在服务器上创建好目录 /root/golang

构建步骤：

#source /etc/profile  #写了这个才会报错！所以注释掉
echo $WORKSPACE
cd $WORKSPACE
export GOPROXY=https://goproxy.cn,direct
#go mod tidy
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 /var/jenkins_home/go/bin/go build -o bin/main static-file-server/main.go  #如果要部署到amd架构的服务器，如此处理。。。
