Jmeter 5.4.1：分布式模式："Connection refused to host: nested exception is: java.net.ConnectException: Connection timed out: connect"

Question

我正在两个 windows VM 中使用 jmeter 5.4.1 设置分布式测试。 在从机中启动 jmeter 服务器。在 jmeter.properties 文件中进行以下更改（主从）

server.rmi.ssl.disable=true

在 master 中添加了 slave 机器 ip 和 运行 从 GUI 模式进行测试。获取连接被拒绝错误：

Answer 1

首先，您的一主一从“架构”没有任何意义，因为您只有一个负载生成器，如果没有进一步扩展的计划 - 您可以 run your JMeter test in command-line non-GUI mode 就是这样。

但是，如果您以后想要添加更多从站，请确保

1. 机器在同一个subnet并且可以互相访问（或者设置适当的路由）
2. 以下端口是 open in Windows Firewall：
   • 端口1099（或任何SERVER_PORT）
   • 你定义的端口为server.rmi.localport
   • 您定义的端口client.rmi.localport
3. 您通过 jmeter-server.bat 命令启动了从站

确保主从使用相同的 rmi 密钥库文件 (rmi_keystore.jks)。我在master上创建了它，然后scp给slaves。
