linux服务基础(一)之CentOS6编译安装httpd2.4

安装前说明：

　　httpd安装依赖于apr-1.4+，apr-util-1.4+

　　CentOS6上默认是apr-1.3, apr-util-1.3

　　先下载httpd2.4、apr-1.5和apr-util-1.5

　　httpd下载地址：http://httpd.apache.org/download.cgi

　　apr和apr-util下载地址：https://apr.apache.org/download.cgi

开始安装：

　　1. 安装开发环境，安装pcre-devel　　

# yum install pcre-devel

　　2. 安装apr：下载路径 https://apr.apache.org/download.cgi

# ./configure --prefix=/usr/local/apr --sysconfdir=/etc/apr
# make && make install

3. 安装apr-util：下载路径 https://apr.apache.org/download.cgi

# ./configure prefix=/usr/local/apr-util --sysconfdir=/etc/apr-util --with-apr=/usr/local/apr
# make && make install

　　4. 安装httpd-2.4

# ./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=most 
--enable-mpms-shared=all --with-mpm=event
# make && make install

　　5. 启动apache服务

　　# /usr/local/bin/apachectl start
　　或者添加PATH环境变量
　　　　# vim /etc/profile.d/httpd.sh
　　　　　　添加： export PATH=/usr/local/apache/bin:$PATH　　//添加apache路径
　　　　#　. /etc/profile.d/httpd.sh　　//重读配置文件
　　　　# apachectl start
　　　　　　 Note: httpd: Could not reliably determine the server's fully qualified domain name,
　　　　　　　　　 using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
　　　　　　　　　# ServerName localhost:80　　//打开注释

　　6. 添加服务脚本: /etc/rc.d/init.d/httpd

#!/bin/bash
#
# httpd        Startup script for the Apache HTTP Server
#
# chkconfig: - 85 15

#        server implementing the current HTTP standards.

添加服务并启动httpd服务
　　# cd /etc/rc.d/init.d
　　# chkconfig --add httpd
　　# vim /etc/profile.d/httpd.sh
　　　　　添加: export PATH=/usr/local/apache/bin:$PATH
　　# ./etc/profile.d/httpd.sh
　　# service httpd start
