安装集群broker时，检测目录已存在

我提前创建了 /opt/mq-cloud,卡住了，一致提示我目录已存在，我就把，return result上面三行给注释了 ，当前系统版本Centos8.2

/**
* 判断目录是否被占用
* @param ip
* @return
*/
public Result dirWrite(String ip, String dir){ String destDir = MQ_CLOUD_DIR + dir; String comm = "if [ ! -d \"" +destDir+ "\" ];then mkdir -p " + destDir +";else echo 0;fi"; SSHResult sshResult = null; try { sshResult = sshTemplate.execute(ip, new SSHCallback() { public SSHResult call(SSHSession session) { SSHResult sshResult = session.executeCommand(comm); return sshResult; } }); } catch (SSHException e) { logger.error("isNotUsed, ip:{},dir:{}", ip, destDir, e); return Result.getWebErrorResult(e); } Result result = wrapSSHResult(sshResult);

   if(result.isOK() && "0".equals(result.getResult())) {
       return Result.getResult(Status.DB_ERROR).setMessage("目录已存在");
   }
    return result;
}

Start at the dirWrite(String ip, String dir) entry point and inspect how its shell command and wrapped result are used during broker installation. Reproduce the installation with an existing /opt/mq-cloud directory on CentOS 8.2, then verify the expected success behavior from the installation output; done means a pre-created directory no longer incorrectly blocks setup.
