编译安装LAMP之httpd

56341

编译安装httpd（httpd 2.4.4，相关软件包可到apache官网上下载）

# hwclock -s 将软件时间同步为硬件时间，防止安装软件时出错

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。这里使用源码包进行升级（apr-1.5.2，apr-util-1.5.4 ）

(1) 编译安装apr

# tar xf apr-1.5.2.tar.bz2

# cd apr-1.5.2

# ./configure --prefix=/usr/local/apr

# make && make install

(2) 编译安装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

# make && make install

(3) httpd-2.4.4编译过程也要依赖于pcre-devel软件包，需要事先安装。

#yum -y install pcre-devel

(4) 可在编译安装httpd时会报错：checking for OpenSSL version >=0.9.7 ... FAILED

#yum -y install openssl-devel

#yum update openssl

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

（含义：--perfix=/usr/local/apache 指定安装路径；--sysconfdir=/etc/httpd 指定配置文件路径；--enable-so  apache核心装载DSO，但实际不编译任何动态模块；--enable-ssl 支持ssl模块；--enable-cgi支持cgi模块；--enable-rewrite 支持url重写；--with-zlib支持zlib库文件；--with-pcre 包含pcre函数；--with-apr=/usr/local/apr 指定apr的路径；--with-apr-util=/usr/local/apr-util 指明apr-util路径；--enable-modules=most 支持模块:支持共享模块；--with-mpm=event加载模块event）

# make && make install

3、修改httpd的主配置文件，设置其Pid文件的路径

#vim /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并加入服务列表：

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

# chkconfig --add httpd

5.提供执行相关命令所需的环境变量

#vim /etc/profile.d/httpd.sh，添加以下内容：

export PATH=$PATH:/usr/local/apache/bin

6.至此，http服务配置结束，可以启动测试了

#service httpd restart
