发布时间：2023-09-06 01:13责任编辑：胡小海关键词：配置

ASF, 协议实现的软件程序, HTTPD特性

HTTP基本应用,客户端工具使用(telnet, elinks, curl)

ASF: Apache Software Foundation Apache 软件基金会

FSF: Free Software Foundaton 自由软件基金会

ASF赖以起家的是: httpd<命名:apache>

http协议实现

httpd配置文件

/etc/httpd/conf/httpd.conf//首次配置需要备份文件:#cp-v/etc/httpd/conf/httpd.conf{,.bak}

配置文件格式

#fgrep‘Section‘/etc/httpd/conf/httpd.conf###Section1:GlobalEnvironment//全局环境：定义httpd通用功能特性###Section2:‘Main‘serverconfiguration//主配置段：一个服务器提供单个站点###Section3:VirtualHosts//虚拟主机：一个服务器提供多个站点

配置指令格式

Directive(指令）Value（值）指令：不区分大小写值：可能区分大小写

1、port

3、MPM并发响应模型Multipath Process Module

10多种[适用在多种平台之上]Linux:prefork,worker,event编译时，一次只能编译单个模块

1）查看当前使用的模块

650) this.width=650;" src="https://s5.51cto.com/wyfs02/M02/07/44/wKiom1nGKIuyujqoAAAPbUPR4hk751.png" title="QQ截图20170923172435.png" alt="wKiom1nGKIuyujqoAAAPbUPR4hk751.png" />

2）查看装载的模块

650) this.width=650;" src="https://s5.51cto.com/wyfs02/M01/A5/F5/wKioL1nGKJvDCFgZAAAxgfE__NM808.png" title="QQ截图20170923172544.png" alt="wKioL1nGKJvDCFgZAAAxgfE__NM808.png" />

3）更换MPM

650) this.width=650;" src="https://s3.51cto.com/wyfs02/M01/07/44/wKiom1nGKXPwz1vpAAAp1vf0O28108.png" title="QQ截图20170923172828.png" alt="wKiom1nGKXPwz1vpAAAp1vf0O28108.png" />

4)MPM配置详解/etc/httpd/conf/httpd.conf <网站的承载能力有一定影响>

#preforkMPM#StartServers:启动服务器后，预留的进程数#MinSpareServers:minimumnumberofserverprocesseswhicharekeptspare#MaxSpareServers:maximumnumberofserverprocesseswhicharekeptspare#ServerLimit:服务器的生命周期内为MaxClients准备的最大值#MaxClients:最大并发数#MaxRequestsPerChild:每个进程最大响应请求数<IfModuleprefork.c>StartServers8MinSpareServers5MaxSpareServers20ServerLimit256MaxClients256MaxRequestsPerChild4000</IfModule>#workerMPM#StartServers:启动服务预留进程数#MaxClients:最大并发数#MinSpareThreads:最小并发数#MaxSpareThreads:maximumnumberofworkerthreadswhicharekeptspare#ThreadsPerChild:每个进程内的线程数#MaxRequestsPerChild:每个线程最多响应请求数<IfModuleworker.c>StartServers4MaxClients300MinSpareThreads25MaxSpareThreads75ThreadsPerChild25MaxRequestsPerChild0//0表示没有上限</IfModule>配置：影响网站的承载能力

PV承载量= \(每秒请求资源数 * 86400 \)/每个页面的资源数 //满载工作

考虑：全天满负荷运行？带宽使用大小？

带宽：每个PV消耗多少KB * PV承载量

4、URL资源路径映射之一：DocRoot <资源路径的根映射为文件系统的哪个目录>

650) this.width=650;" src="https://s5.51cto.com/wyfs02/M02/A5/FC/wKioL1nHGlzzHj3cAAAyVpT-8NM686.png" title="QQ截图20170924103717.png" alt="wKioL1nHGlzzHj3cAAAyVpT-8NM686.png" />

使用示例：

默认配置

在配置文件中,定义DocumentRoot指令

DocumentRoot "/var/www/html"

给出默认主页

#cat>/var/www/html/index.html<<EOF<html><head><title>MageEdu</title></head><body><h1>Hello</h1><p><ahref="https://s5.51cto.com/wyfs02/M00/07/31/wKiom1nEuS7Tii_KAAA2TqP_0qY316.png">haha</p></body></html>EOF

重载配置文件

#httpd-t//先测试语法#servicehttpdreload//重载配置文件

在浏览器中访问时:

DocumentRoot "/www/htdocs"

准备根映射路径

#install-d/www/htdocs#echo‘TestPage‘>/www/htdocs/index.html

重载配置文件

#httpd-t#servicehttpdreload

二次测试

基于名称完成不同虚拟主机的识别

封装时:HTTP首部、TCP首部、IP首部、帧首部..

Host: 浏览器键入的主机名 //"应用层首部"中附加,非通信子网

虚拟主机配置格式

1、基于IP,配置虚拟主机(不易记，IP需要购买)

#DocumentRoot"/www/htdocs"<VirtualHost192.168.206.128:80>ServerNameweb1.magedu.comDocumentRoot"/www/web1/htdocs"</VirtualHost><VirtualHost192.168.206.129:80>ServerNameweb2.magedu.comDocumentRoot"/www/web2/htdocs"</VirtualHost>#mkdir-pv/www/{web1,web2,web3,web4,web5,web6}/htdocs#echo"web1.magedu.com">/www/web1/htdocs/index.html#echo"web2.magedu.com">/www/web2/htdocs/index.html#ipaddradd192.168.206.139/24deveth0

2、基于端口,配置虚拟主机（用的少）

Listen8080Listen8888<VirtualHost192.168.206.139:8080>ServerNameweb3.magedu.comDocumentRoot"/www/web3/htdocs"</VirtualHost><VirtualHost192.168.206.139:8888>ServerNameweb4.magedu.comDocumentRoot"/www/web4/htdocs"</VirtualHost>#echo"web3.magedu.com">/www/web3/htdocs/index.html#echo"web4.magedu.com">/www/web4/htdocs/index.html

3、基于Host,配置虚拟主机（在应用层封装Host首部即可）

NameVirtualHost*:80<VirtualHost*:80>ServerNameweb5.magedu.comDocumentRoot"/www/web5/htdocs"</VirtualHost><VirtualHost*:80>ServerNameweb6.magedu.comDocumentRoot"/www/web6/htdocs"</VirtualHost>#echo"web5.magedu.com">/www/web5/htdocs/index.html#echo"web6.magedu.com">/www/web6/htdocs/index.html

#httpd-t#servicehttpdreload
