在使用 jmeter 进行压力测试期间 Apache httpd 连接被拒绝

Question

现在，我在windows(jmeter.bat)中使用jemter进行压力测试。

Number of Threads = 100
Ramp-up period = 0 
Loop count = 1000

但是在 20~30 秒后在 jmeter 中引发连接被拒绝错误。我在 /usr/local/apache/logs/error.log 或 /usr/local/apache/logs/access.log 中找不到连接被拒绝的错误。

测试是 HTTP GET，index.html("It's works") Apache MPM 正在运行，设置如下：

<IfModule mpm_worker_module>
StartServers            8
MinSpareThreads         64
MaxSpareThreads        1024 
ThreadsPerChild         64
MaxRequestWorkers       512
MaxConnectionsPerChild   0

jmeter问题？任何 apache 设置问题？

jmeter 异常如下：

这不是 jmeter 问题：

检查 jmeter 和 apache 之间的组件（防火墙、负载均衡器、ddos 保护...）
检查 apache 设置，慢慢检查这个 rampup，看看你从哪个负载开始得到这些错误。
