Redis服务器在使用Apache Bench进行基准测试时拒绝连接

Question

在安装了Apache和php的计算机上，redis中的数据很少。我正在使用php通过其api从redis获取数据。我必须测试来自APache2 Web服务器的Redis服务器响应时间。为此，我使用了ab即Apache Bench。以下是我在配置Apache2和Redis的同一系统上执行的命令。

ab -n 12000 -c 3000 -g andr_apache.csv http://10.10.12.129:8080/redis/read.php

然后是我们的

This is ApacheBench, Version 2.3 <$Revision: 1807734 $>

Benchmarking 10.11.21.129 (be patient)

apr_socket_recv: Connection reset by peer (104)
Total of 11701 requests completed

最后一个错误表明连接已重置。因此，以下是Apache2错误日志文件中的错误。

[Thu Mar 21 09:43:19.142446 2019] [php7:warn] [pid 22276] [client 10.11.21.141:38668] PHP Warning:  fsockopen(): unable to connect to 127.0.0.1:6379 (Cannot assign requested address) in /var/www/html/andr/redis/read.php on line 79

如果将请求数减少到3000，将用户数减少到3000以下，则作业成功完成，但是当我增加限制时，出现此错误。 Apache2和Reids中是否存在任何配置问题。我主要使用默认设置。 以下是成功运行的情节。为什么突然出现峰值。
