安装环境说明：

操作系统：Centos 6.5 -64bit

安装路径：/usr/local/memcached

开始编译memcached

安装编译需要的扩展包

yum install libevent libevent-devel

开始编译memcached

tar -zxvf memcached-1.4.21.tar.gzcd memcached-1.4.21./configure --prefix=/usr/local/memcachedmakemake install

安装PHP memcache 扩展包

tar -zxvf memcache-2.2.7.tgzcd memcache-2.2.7/usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-config make make install# 安装成功后会输出这个地址，这是php扩展模块文件夹/usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/

创建memcached自启动脚本

#! /bin/sh## chkconfig: - 55 45# description:  The memcached daemon is a network memory cache service.# processname: memcached# config: /etc/sysconfig/memcached# Source function library - for other linux#. /etc/rc.d/init.d/functions# Source function library - for suse linux. /lib/lsb/init-functionsip="192.168.25.129"             # 绑定侦听的IP地址port="11211"                    # 服务端口username="root"                 # 运行程序的用户身份max_memory=64                   # default: 64M | 最大使用内存max_connection=1024             # default: 1024 | 最大同时连接数if [ -f /etc/sysconfig/memcached ];then  . /etc/sysconfig/memcachedfi# Check that networking is up.if [ "$NETWORKING" = "no" ]then  exit 0fiRETVAL=0prog="memcached"pidfile=/tmp/memcached.pidbasedir=/usr/local/memcachedcmd=${basedir}/bin/memcachedstart () {  echo -n $"Starting service：$prog "  chown $username $basedir  $cmd -d -p $port -u $username  -m $max_memory -c $max_connection -P $pidfile $OPTIONS  RETVAL=$?  echo  [ $RETVAL -eq 0 ] && touch /var/lock/subsys/memcached  return $retval}stop() {    echo -n $"Stopping service: $prog  "    current_user=$(whoami)    pidlist=$(ps -ef | grep $current_user | grep memcached | grep -v grep | awk '{print $2}')    for pid in $pidlist ; do        kill -9 $pid        if [ $? -ne 0 ]; then           return 1        fi    done    RETVAL=$?    echo    [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/memcached}restart () {  stop  start}# See how we were called.case "$1" in  start)  start  ;;  stop)  stop  ;;  status)  status memcached  ;;  restart|reload)  restart  ;;  condrestart)  [ -f /var/lock/subsys/memcached ] && restart || :  ;;  *)  echo $"Usage: $0 {start|stop|status|restart|reload|condrestart}"  exit 1esacexit $?

脚本配置

# 将此脚本cp到/etc/init.d目录下并改名为memcached,然后增加执行权限cp memcached /etc/init.d/memcachedchmod a+x /etc/init.d/memcached

配置开启自启动

chkconfig --add memcached              # 增加开启启动chkconfig --level 2345 memcached on    # 设置启动级别

测试启动，停止，重启memcached

# 服务启动，停止service memcached startservice memcached stop# init.d目录启动，停止/etc/init.d/memcached start/etc/init.d/memcached stop

配置PHP支持memcached

编辑php.ini文件

vim /usr/local/php/etc/php.ini# 修改以下内容extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/"# 增加扩展到phpextension = memcache.so

重新启动php-fpm

/etc/init.d/php-fpm restart

在php测试下是否成功

    connect('192.168.25.129', 11211);$memcache->set('key', 'test');echo $memcache->get('key');

结果截图( 成功输出了缓存值 )：

总结

到这里我们memcache缓存就编译安装完成了，memcache是很强大的缓存系统，加油吧....如果兄弟们安装遇到问题可以加我QQ:418250505 大家一起讨论，共同进步~！
