JMeter -Tank无法运行JMeter -无法访问Yandex可执行文件或该文件不存在

Question

我正在尝试在基于Ubuntu18的Yandex Cloud实例中从Yandex.Tank启动JMeter。

此处安装了JMeter：/home/tank/apache-jmeter-5.2.1/bin/jmeter

如果我使用以下路径运行JMeter，它将成功启动：

/home/tank/apache-jmeter-5.2.1/bin/jmeter -n -t ReloadTest.jmx -l result-1.jtl -e -o ./result-1

当我运行yandex-tank时，出现错误消息：

[ERROR] Test interrupted:
<type 'exceptions.RuntimeError'>: Unable to access to JMeter executable file or it does not exist: 
/home/tank/apache-jmeter-5.2.1/bin/jmeter

load.yaml：

phantom:
  enabled: false
jmeter:
  enabled: true
  jmx: ReloadTest.jmx
  buffered_seconds: 10
  jmeter_path: /home/tank/apache-jmeter-5.2.1/bin/jmeter
  jmeter_ver: 5.2
  ext_log: all
overload:
  enabled: true
  package: yandextank.plugins.DataUploader
  token_file: "token.txt"

我试过了，但没有成功：

chmod +x /home/tank/apache-jmeter-5.2.1/bin/jmeter
chmod 777 /home/tank/apache-jmeter-5.2.1/bin/jmeter

我无法使用最新的YandexTank 1.12.8.1重现您的问题，您可能希望使用pip更新您当前的安装，如下所示：

pip install https://api.github.com/repos/yandex/yandex-tank/tarball/master

如果仍然遇到问题-使用-v命令行参数运行YandexTank，应该会生成更多详细的调试消息，以便您能够找出问题所在

您还可以尝试通过change the ownership of the whole JMeter folder连接到tank用户，如下所示：

chown -R tank /home/tank/apache-jmeter-5.2.1

最后，您可以考虑切换到更好地支持JMeter并支持automatically downloading JMeter with plugins的Taurus工具，这样您就不必担心安装JMeter了。有关更多详细信息，请查看Navigating your First Steps Using Taurus文章。
