golang ssh 遠程執行命令(有一些命令會報command not found)

func sshSession(user, password, host string, port int) (sshSession *ssh.Session, err error) { //參數: 遠程服務器用戶名, 密碼, ip, 端口
   sshClient, err := connector(user, password, host, port) //鏈接ssh
   if err != nil {
      fmt.Println("鏈接ssh失敗", err)
      return
   }

   if sshSession, err = sshClient.NewSession(); err != nil { //建立客戶端
      fmt.Println("建立客戶端失敗", err)
      return
   }

   return
}

func connector(user, password, host string, port int) (sshClient *ssh.Client, err error) {
   auth := make([]ssh.AuthMethod, 0)
   auth = append(auth, ssh.Password(password))

   clientConfig := &ssh.ClientConfig{
      User:    user,
      Auth:    auth,
      Timeout: 30 * time.Second,
      HostKeyCallback: func(hostname string, remote net.Addr, key ssh.PublicKey) error {
         return nil
      },
   }

   addr := host + ":" + strconv.Itoa(port)
   sshClient, err = ssh.Dial("tcp", addr, clientConfig) //鏈接ssh
   if err != nil {
      fmt.Println("鏈接ssh失敗", err)
      return
   }

   return
}

func main() {
   //session, err := go_utils.SshSession("root", "ubZFVU9RSKcTuTZe", "47.107.94.236", 22)
   session, err := go_utils.SshSession("root", "Xu765529", "47.92.199.4", 22)
   if err != nil {
      log.Fatal(err)
   }
   defer session.Close()

   session.Stdout = os.Stdout
   session.Stderr = os.Stderr
   session.Stdin = os.Stdin
   err = session.Run("/usr/local/start.sh") //腳本路徑
   if err != nil {
      fmt.Println(err)
   }
}


看一下腳本內容:

在服務器上直接運行腳本:

 

hello world 和 2個java的版本號, 然而程序運行的實際狀況:

有一個java命令報command not found, 是由於ssh在鏈接遠程的環境變量中不包含可執行文件的路徑, 因此要本身加上路徑
