本文主要介绍了LAMP的安装。

Linux+Apache+Mysql/MariaDB+Perl/PHP/Python一组常用来搭建动态网站或者服务器的开源软件，本身都是各自独立的程序，但是因为常被放在一起使用，拥有了越来越高的兼容度，共同组成了一个强大的Web应用程序平台

文所用环境和安装包为CentOS6.5+httpd 2.4.6+mysql-5.5.33+php-5.4.19+xcache-3.0.3。

一、编译安装apache

1、解决依赖关系

httpd-2.4.6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?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

(3) httpd-2.4.6编译过程也要依赖于pcre-devel软件包，需要事先安装。此软件包系统光盘自带，因此，找到并安装即可。

参考命令:

#yum install -y pcre-devel

2、编译安装httpd-2.4.6

首先下载httpd-2.4.6到本地

# tar xf httpd-2.4.6.tar.bz2

# cd httpd-2.4.6

# ./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

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、提供SysV服务脚本/etc/rc.d/init.d/httpd，内容如下：

#!/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

fi

# Start httpd in the C locale by default.

HTTPD_LANG=${HTTPD_LANG-"C"}

# This will prevent initlog from swallowing up a pass-phrase prompt if

# mod_ssl needs a pass-phrase from the user.

INITLOG_ARGS=""

# Set HTTPD=/usr/sbin/httpd.worker in /etc/sysconfig/httpd to use a server

# with the thread-based "worker" MPM; BE WARNED that some modules may not

# work correctly with a thread-based MPM; notably PHP will refuse to start.

# Path to the apachectl script, server binary, and short-form for messages.

apachectl=/usr/local/apache/bin/apachectl

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

prog=httpd

pidfile=${PIDFILE-/var/run/httpd.pid}

lockfile=${LOCKFILE-/var/lock/subsys/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

        RETVAL=$?

    fi

    echo

}

# See how we were called.

case "$1" in

  start)

  start

  ;;

  stop)

  stop

  ;;

  status)

        status -p ${pidfile} $httpd

  RETVAL=$?

  ;;

  restart)

  stop

  start

  ;;

  condrestart)

  if [ -f ${pidfile} ] ; then

    stop

    start

  fi

  ;;

  reload)

        reload

  ;;

  graceful|help|configtest|fullstatus)

  $apachectl $@

  RETVAL=$?

  ;;

  *)

  echo $"Usage: $prog {start|stop|restart|condrestart|reload|status|fullstatus|graceful|help|configtest}"

  exit 1

esac

exit $RETVAL

而后为此脚本赋予执行权限：

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

加入服务列表：

# chkconfig --add httpd

接下来就可以启动服务进行测试了。

#service httpd start
