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memcachedtar -zxvf memcached-1.4.21.tar.gz cd memcached-1.4.21 ./configure –prefix=/usr/local/memcached make make install
安装PHP memcache 扩展包tar -zxvf memcache-2.2.7.tgz cd 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-functions ip=”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/memcached fi # Check that networking is up. if [ “$NETWORKING” = “no” ] then exit 0 fi RETVAL=0 prog=”memcached” pidfile=/tmp/memcached.pid basedir=/usr/local/memcached cmd=${basedir}/bin/memcached start () { 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 1 esac exit $?
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/memcached chmod 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 start service 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php extension = 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…
