CentOS 6.6下编译安装Httpd2.4

CentOS7的镜像中已经提供了httpd2.4的rpm包,httpd2.4相对于httpd2.2有较大的改进,在CentOS6下只能通过Apache官方网站提供的源码包编译安装。

httpd2.4新特性

MPM支持运行DOS机制;

支持event MPM;

支持异步读写;

支持每模块及每个目录分别使用各自的日志级别;

每请求配置;<If>

增强版的表达式分析器;

支持毫秒级的keepalive timeout;

基于FQDN的虚拟主机不再需要NameVirtualHost指令;

支持用户自定义变量;

新模块

mod_proxy_fcgi:与PHP结合的模块;

mod_ratelimit:限制下载速率的模块;

mod_remoteip:设定远程客户端IP;

修改的配置机制:不再支持使用order,allow,deny定义基于ip的访问控制,改为require;

编译安装Httpd2.4:

httpd2.4依赖于apr和apr-util,1.4以上版本,所以需要一同编译安装;

apr:ApachePortable Runtime,Apache可移植运行时;

官网:apr.apache.org

实验环境

系统版本:CentOS 6.6x86_64;

httpd源码包:httpd-2.4.16.tar.bz2;

apr源码包:apr-1.5.2.tar.bz2;

apr-util源码包:apr-util-1.5.4.tar.bz2

实验前提

关闭防火墙和SELinux;

安装编译环境;

# yum groupinstall "Server Platform Development" "Developmenttools"

实验过程

一、安装服务;

apr:

# tar xf apr-1.5.2.tar.bz2
# cd apr-1.5.2
#./configure --prefix=/usr/local/apr
# make && make install

apr-util:       

# tar xf apr-util-1.5.4.tar.bz2
# cd apr-util-1.5.4
#./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/
    --with-apr=/usr/local/apr/    :指明apr安装位置;
# make && make install

httpd:

# tar xf httpd-2.4.16.tar.bz2
# cd httpd-2.4.16
#./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --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=all --enable-mpms-shared=all --with-mpm=event
# make && make install

httpd编译参数解释:

--prefix=/usr/local/apache    :安装位置;
--sysconfdir=/etc/httpd    :配置文件位置;
--enable-so    :支持DSO动态装载模块;
--enable-ssl    :支持SSL/TLS,可实现https协议访问,需要安装openssl-devel;
--enable-cgi    :支持CGI脚本;
--enable-rewrite    :支持URL重写;
--with-zlib    :使用指定的zlib压缩库,不指定路径会自动寻找;
--with-pcre    :使用指定的pcre库,增强的正则表达式分析工具;不指定路径会自动寻找 需已安装pcre-devel;
--with-apr=/usr/local/apr    :指定依赖apr程序安装位置;
--with-apr-util=/usr/local/apr-util    :指定依赖apr-util程序安装位置;
--enable-modules=all    :支持动态启用模块;all:所有,most:常用;
--enable-mpms-shared=all    :编译并共享模块;
--with-mpm=event    :默认启用模块;{prefork|worker|event}

二、参数配置

接下来是安装完成之后的参数配置;

添加环境变量,并重读文件:

# vim /etc/profile.d/httpd.sh
> export PATH=/usr/local/apache/bin:$PATH
# source /etc/profile.d/httpd.sh

导出头文件;

# ln -sv /usr/local/apache/include /usr/include/httpd

导出man手册;

# vim /etc/man.config
> MANPATH /usr/local/apache/man

启动服务,查看监听端口;

# apachectl start
# ss –tnl

访问测试;

提供服务脚本:

可使用rpm包安装提供的脚本修改使用:

# vim /etc/rc.d/init.d/httpd
> #!/bin/bash
> #
> # httpdStartup script for the Apache HTTP Server
> #
> # chkconfig:- 85 15

修改主配置文件指定pidfile;

# vim /etc/httpd/httpd.conf
> PidFile "/var/run/httpd.pid"

脚本执行权限;

1 # chmod +x /etc/rc.d/init.d/httpd

添加服务,测试脚本;

# chkconfig httpd –add
# chkconfig httpd on

# service httpd stop
# service httpd start
# service httpd restart
# service httpd reload
