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
