CentOS 6.5安装配置LAMP
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
本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
(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
