Linux下Jmeter分布式压测集群搭建与实战指南分布式压测是突破单机性能瓶颈、模拟超高并发场景的核心技术。其原理是通过主从架构，将压测任务分发到多台压力机协同执行，从而汇聚计算与网络资源，实现远超单机能力的负载模拟。这项技术的核心价值在于能够更真实地触发系统在高压力下的潜在问题，如数据库连接池耗尽、缓存雪崩等。在应用场景上，它广泛应用于电商大促、秒杀活动等需要验证系统极限性能的环节。本文聚焦于Jmeter这一主流工具，详细解析如何在Linux环境下，从零搭建一个高可用的分布式压测集群，涵盖集群架构设计、网络与RMI通信配置、系统资源监控以及实战中常见的时阅读详情

问题描述同上，在系统防火墙中已经将RMI的端口添加了例外。而且通过Telnet 命令也可以正常连接，报错信息描述如下：
