我是靠谱客的博主慈祥紫菜，最近开发中收集的这篇文章主要介绍httpd长连接设置KeepAlive，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

长连接KeepAlive

httpd的持久链接主要依靠KeepAlive
有以下几个相关的指令‘

KeepAlive On|Off #是否开启KeepAlive长连接
KeepAliveTimeout 15 #长连接多久算是超时，超时之后自动断开长连接
MaxKeepAliveRequests 100 #长连接最多接受多少个请求。请求数量大于改值则自动断开。

在主配置文件/usr/local/httpd/conf/httpd.conf添加

KeepAlive  On|Off
KeepAliveTimeout  15
MaxKeepAliveRequests  100

检查一下配置文件并重启
httpd -t
httpd -k restart

用telnet模拟请求测试一下是否超时会断开

yum install telnet -y
[root@www ~]# telnet 192.168.253.128 80  ##访问的服务器IP  端口
