安装环境说明：

操作系统：Centos 6.7 -64bit
软件版本：memcached-1.4.33、memcache-2.2.7、libevent-2.0.22
安装路径：/usr/local/libevent /usr/local/memcached

开始编译libevent

方式一：
yum install libevent-devel
方式二：编译安装
tar -zxxf libevent-2.0.22-stable.tar.gz
 ./configure --prefix=/usr/local/libevent
 make && make install
echo "/usr/local/libevent/lib" > /etc/ld.so.conf.d/libevent.conf
ldconfig 

开始编译memcached

tar -zxvf memcached-1.4.33.tar.gz 
cd memcached-1.4.33
./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent
make && make install

创建memcached自启动脚本

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
service memcached start
service memcached stop

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-20131226

配置PHP支持memcached

vim /etc/php.ini 
#编辑php.ini文件增加以下内容
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226"
extension = memcache.so
#重新启动php-fpm
/etc/init.d/php-fpm restart

在php测试下是否成功

<?php
echo "www.jcwtime.cn<br/>\n";

$mem = new Memcache;
$mem->connect("192.168.10.101", 11211)  or die("Could not connect");

$version = $mem->getVersion();
echo "Server's version: ".$version."<br/>\n";

$mem->set('key', 'Hello World', 0, 600) or die("Failed to save data at the memcached server");
echo "Store data in the cache (data will expire in 600 seconds)<br/>\n";

$get_result = $mem->get('key');
echo "$get_result is from memcached server.";         
?>
