Web服务其三编译安装httpd-2.4.9

更新时间:2022-08-13 11:25:52

之前已经讲过web基本概念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

1

[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

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

1

3
4
#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

1
2
3
4
#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

1
[root@bogon apache]# ln -s /usr/local/apache/include/ /usr/include/httpd24

2、输出二进制程序

1
2
3
#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

1
2
#vim /etc/man.config
#MANPATH /usr/local/apache/man

五、测试

1

3
4
5
# 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

1
#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

1
2
# vim /etc/httpd24/httpd.conf
PidFile "/var/run/httpd24.pid"
