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]# wgethttps://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 ApacheHTTP Server is a powerful and flexible HTTP/1.1 compliant
webserver. 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.
TheLatest 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
------------------
Forcomplete 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
