Web服务其三编译安装httpd-2.4.9

2014-03-20 03:09 489 查看
之前已经讲过web基本概念与http请求响应报文，下面将以编译方式来安装http2.4.9服务器软件。与httpd2.2相比，httpd 2.4增加了如下特性：
1、MPM可于运行时装载；
2、Event MPM
3、异步读写
4、在每模块及每目录上指定日志级别；
5、每请求配置；<If>, <ElseIf>, <Else>；
6、增强的表达式分析器；
7、毫秒级的KeepAlive Timeout；
8、基于域名的虚拟主机不再需要NameVirtualHost指令；
9、降低了内存占用；
10、支持在配置文件中使用自定义变量；
新增加的模块：
mod_proxy_fcgi（可以提供fcgi代理）
mod_proxy_scgi（支持scgi协议）
mod_proxy_express
mod_remoteip（能够强大的匹配客户端的IP地址）
mod_session（保持用户会话）
mod_ratelimit（限制每个用户的带宽）
mod_request（请求模块，对请求做强大的过滤）
等等；
一、准备阶段
本机环境
[root@bogon ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
[root@bogon ~]# uname -r
2.6.32-431.el6.x86_64
预安装软件包
[root@bogon run]# yum groupinstall -y  "Server Platform Development"
[root@bogon run]# yum groupinstall -y "Development tools"
[root@bogon run]#yum install -y pcre-7.8-6.el6.x86_64 pcre-devel-7.8-6.el6.x86_64
二、下载apr-1.5.0、apr-util-1.5.3、http2.4.9
[root@bogon Downloads]#wget http://mirrors.cnnic.cn/apache//httpd/httpd-2.4.9.tar.bz2 [root@bogon Downloads]#wget  ftp://ftp.mirrorservice.org/sites/ftp.apache.org/apr/apr-util-1.5.3.tar.bz2 [root@bogon Downloads]#wget http://archive.apache.org/dist/apr/apr-1.5.0.tar.bz2[/code]三、编译安装软件包 1、apr-1.5.0.tar.bz2
apr:apache portable run-time是apache运行时环境，为了能使apache运行在不同的平台上
并且能使用同样的机制，所以apr能够抹除不同系统的数据库，让apache运行环境的机制都一样，
并且能让apache的某些特性跨平台的使用。
[root@bogon local]# tar xf apr-1.5.0.tar.bz2
[root@bogon local]#cd apr-1.5.0
[root@bogon apr-1.5.0]# ./configure --prefix=/usr/local/apr
[root@bogon apr-1.5.0]#make && make install
2、apr-util-1.5.3.tar.bz2
#tar xf apr-util-1.5.3.tar.bz2
#cd apr-util-1.5.3
#./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
#make && make install
3、http2.4.9.tar.bz2

#tar xf httpd-2.4.9.tar.bz2
# cd httpd-2.4.9
#./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd24 --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --enable-modules=most --enable-mpms-shared=all --with-mpm=event
#make && make install
 编译参数说明：
--prefix=/usr/local/apache：指定安装路径
--sysconfdir=/etc/httpd24：指定配置文件存放位置
--enable-so：允许运行时加载DSO模块
--enable-ssl： 提供对安全套接字层(SSL)和传输层安全(TLS)协议实现高强度加密传输
--enable-cgi：提供对CGI脚本执行的支持
--enable-rewrite：支持重写
--with-zlib：是支持zlib库
--with-pcre：启用正则表达式
--with-apr=/usr/local/apr：Apache可移植运行时(APR)是httpd源码的一部分并会自动与httpd一起创建。如果你想使用一个已经存在的APR ，就必须在这里指定apr-config脚本的路径。
--with-apr-util=/usr/local/apr-util/：Apache可移植运行时工具包(APU)是httpd源码的一部分并会自动与httpd一起创建。如果你想使用一个已经存在的APU ，就必须在这里指定apu-config脚本的路径。
--enable-modules=most：启用大多数常用模块。
--enable-mpms-shared=all：启用MPM支持的所有模式。
--with-mpm=event：设置默认MPM为event。
四、参数设置
1、导出库文件
[root@bogon apache]# ln -s /usr/local/apache/include/ /usr/include/httpd24
2、输出二进制程序
#vim /etc/profile.d/http24.sh
export PATH=/usr/local/apache/bin:$PATH
#source /etc/profile.d/http24.sh
3、导出man手册

#vim /etc/man.config
#MANPATH /usr/local/apache/man
五、测试
# apachectl start
# ss -tunl |grep ":80"
tcp    LISTEN     0      128                   :::80                   :::*
# curl 192.168.1.114
<html><body><h1>It works!</h1></body></html>
六、添加服务脚本
1、先关掉apache服务
#apachectl stop
2、修改httpd的主配置文件，设置其Pid文件的路径，编辑/etc/httpd24/httpd.conf，添加如下行即可
# vim /etc/httpd24/httpd.conf
PidFile "/var/run/httpd24.pid"
3、修改服务脚本
#!/bin/bash
#
# httpd        Startup script for the Apache HTTP Server
#
# chkconfig: - 85 15
# description: The Apache HTTP Server is an efficient and extensible  \
#          server implementing the current HTTP standards.
# processname: httpd
# config: /etc/httpd/conf/httpd.conf
# config: /etc/sysconfig/httpd
# pidfile: /var/run/httpd/httpd.pid
