LAMP架构应用实战—Apache服务介绍与安装01

一:Apache是什么

Apache是Apache基金会开发的一个高性能、功能强大、安全可靠、灵活的开放源码的WEB服务软件

 

二:Apache的特点与应用场景

1****、特点

功能强大、配置简单、速度快、应用广泛、性能稳定可靠,同时还可以做代理服务器或负载均衡

2****、应用场景

ü  运行静态页面、图片(据说处理静态小文件能力不如nginx)

ü  结合PHP引擎运行PHP等程序,LAMP组合

ü  结合tomcat、resin运行jsp、java等程序

ü  作代理、负载均衡,rewrite规则过滤等

三:Apache的安装

一般系统默认自带安装的Apache版本相对较低,安装之前先查看下是否自带Apache服务

1、检查系统是否安装Apache****服务

[root@Centos~]# rpm -qa httpd*

httpd-2.2.15-54.el6.centos.x86_64

httpd-tools-2.2.15-54.el6.centos.x86_64

 

2、如果没有自带Apache****服务软件,可以不需要进行下面的卸载

[root@Centos~]# rpm -e –nodeps httpd-2.2.15-54.el6.centos.x86_64

warning:/etc/httpd/conf/httpd.conf saved as /etc/httpd/conf/httpd.conf.rpmsave

[root@Centos~]# rpm -e –nodeps httpd-tools-2.2.15-54.el6.centos.x86_64

3****、卸载完成后检查下卸载是否成功

[root@Centos ~]# rpm -qa|grep httpd

 

4****、创建用于存放下载的软件工具目录

[root@Centos ~]# mkdir -p /Downloads/tools

[root@Centos ~]# cd /Downloads/tools

[root@Centos tools]# ls

 

5、进入官方网站下载apache****软件到当前目录

[root@Centos tools]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/httpd/httpd-2.4.23.tar.gz

–2016-09-11   23:44:41– https://mirrors.tuna.tsinghua.edu.cn/apache/httpd/httpd-2.4.23.tar.gz

6****、查看下载的文件并解压

[root@Centos tools]# ls

httpd-2.4.23.tar.gz

[root@Centos tools]# tar zxvf httpd-2.4.23.tar.gz

**…………………………………………………………………………………….**具体解压过程此处省略

 

切换到软件目录下,查看具体内容

[root@Centos tools]# cd httpd-2.4.23

[root@Centos httpd-2.4.23]# ls -ll

查看apache介绍

[root@Centos httpd-2.4.23]# cat README                   

  Apache HTTP Server

What is it? 

———–

The Apache HTTP Server is a powerful and flexible HTTP/1.1 compliant

  web server.  Originally designed as a replacement for the NCSA HTTP

  Server, it has grown to be the most popular web server on the

  Internet.  As a project of the Apache Software Foundation, the

  developers aim to collaboratively develop and maintain a robust,

  commercial-grade, standards-based server with freely available

  source code.

 

  The Latest Version

  ——————  后面的内容此处省略

介绍如何安装apache服务

[root@Centos httpd-2.4.23]# cat INSTALL 

 

APACHE INSTALLATION OVERVIEW

 

Quick Start - Unix

 ——————

  For complete installation documentation, see [ht]docs/manual/install.html or

  http://httpd.apache.org/docs/2.4/install.html

   $ ./configure –prefix=PREFIX

     $ make

     $ make install

     $ PREFIX/bin/apachectl start

更多内容可自行查看文档介绍

7****、编译安装

[root@Centoshttpd-2.4.23]# ./configure

–prefix=/application/apache2.4.23

–enable-deflate

–enable-expires

–enable-headers

–enable-modules=most

–enable-so

–with-mpm=worker

–enable-rewrite

参数说明如下:

**–prefix=/application/apache2.4.23   **

表示指定安装路径为**/application/apache2.4.23 ,如果不指定,默认为/usr/local/apache2**

**–enable-deflate **

提供对内容的压缩传输编码支持,提高传输速度,提升访问体验,生产环境中这是重要调优参数之一

** –enable-expires**

激活允许通过配置文件控制** HTTP的“Expires:”和“Cache-Control:**”头内容,即对网站的图片等内容,提供在客户端浏览器缓存的设置,也是生产环境重要调优参数之一

**–enable-headers **

提供允许对HTTP请求头的控制

**–enable-modules=most **

编译安装模块** most表示包含大部分模块到httpd**

**–enable-so **

激活apache服务的DSO(动态共享对象)支持,即可在以后以DSO的方式编译安装共享模块

**–with-mpm=worker **

选择apache mpm的模式为worker模式,此模式原理是更多的使用线程来处理请求,可以处理更多并发请求,也是apache调优的一个重要参数

–enable-rewrite

提供基于URL规则的重写功能,根据已知URL地址,转换其它要访问的URL地址

出现错误提示:****configure: error: APR not found

解决方法如下

下载APR并进行安装
