编译安装apache

1.安装依赖库：“Development  Tools”  “Server Platform Development”  pcre-devel

2.安装apr,apr-util

　　从yum源安装或去apr网站下载安装包，这是采用编译安装。

  安装apr：

　　cd apr

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

  安装apr-util：

　　cd apr-util

　　./configure --prefilx=/usr/local/apr-util  --with-apr=/usr/local/apr

3.安装apache

  ./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-ssl --enable-so --enable-rewrite --enable-zlib --enable-pcre  --enable-cache --enable-cache-disk  --enable-cgi --enable-modules=most --enable-mpms-shared=all --with-mpm=prefork

4.修改httpd的主配置文件，设置其Pid文件的路径

  在httpd.conf文件中添加如下行：

　　PidFile “/var/run/httpd.pid”

5.添加环境变量

 vim /etc/profile.d/httpd.sh

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

6.

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

# 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
