一、编译安装apache

1、解决依赖关系

httpd-2.4.4需要较新版本的apr和apr-util，因此需要事先对其进行升级。升级方式有两种，一种是通过源代码编译安装，一种是直接升级rpm包。这里选择使用编译源代码的方式进行

(1) 编译安装apr

tar xf apr-1.4.6.tar.bz2

cd apr-1.4.6

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

(2) 编译安装apr-util

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

2、编译安装httpd-2.4.4

tar xf httpd-2.4.4.tar.bz2
cd httpd-2.4.4

./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=most --with-mpm=event
make && make install

3、修改httpd的主配置文件，设置其Pid文件的路径

编辑/etc/httpd/httpd.conf，添加如下行即可：
PidFile  "/var/run/httpd.pid"

4、启动脚本

vim /etc/rc.d/init.d/httpd

#!/bin/bash
#
# httpd        Startup script for the Apache HTTP Server
#
# chkconfig: - 85 15
# description: Apache is a World Wide Web server.  It is used to serve \
#        HTML files and CGI.
# processname: httpd
# config: /etc/httpd/conf/httpd.conf
# config: /etc/sysconfig/httpd
# pidfile: /var/run/httpd.pid

# Source function library.
. /etc/rc.d/init.d/functions

if [ -f /etc/sysconfig/httpd ]; then
        . /etc/sysconfig/httpd

# mod_ssl needs a pass-phrase from the user.

httpd=${HTTPD-/usr/local/apache/bin/httpd}

RETVAL=0

start() {
        echo -n $"Starting $prog: "
        LANG=$HTTPD_LANG daemon --pidfile=${pidfile} $httpd $OPTIONS
        RETVAL=$?
        echo
        [ $RETVAL = 0 ] && touch ${lockfile}
        return $RETVAL
}

stop() {
 echo -n $"Stopping $prog: "
 killproc -p ${pidfile} -d 10 $httpd
 RETVAL=$?
 echo
 [ $RETVAL = 0 ] && rm -f ${lockfile} ${pidfile}
}
reload() {
    echo -n $"Reloading $prog: "
    if ! LANG=$HTTPD_LANG $httpd $OPTIONS -t >&/dev/null; then
        RETVAL=$?
        echo $"not reloading due to configuration syntax error"
        failure $"not reloading $httpd due to configuration syntax error"
    else
        killproc -p ${pidfile} $httpd -HUP

 exit 1
esac
