　　memcached数据导入和导出

　　PHP链接memcached
先安装php的memcache扩展
cd /usr/local/src/
wget  http://www.apelearn.com/bbs/data/attachment/forum/memcache-2.2.3.tgz
tar zxf memcache-2.2.3.tgz 
cd memcache-2.2.3
/usr/local/php-fpm/bin/phpize
./configure --with-php-config=/usr/local/php-fpm/bin/php-config
make && make install
安装完后会有类似这样的提示：Installing shared extensions: /usr/local/php-fpm/lib/php/extensions/no-debug-non-zts-20131226/
然后修改php.ini添加一行extension="memcache.so“
检查/usr/local/php/bin/php-fpm -m

　　下载测试脚本
curl www.apelearn.com/study_v2/.memcache.txt > 1.php 2>/dev/null
1.php内容也可以参考https://coding.net/u/aminglinux/p/yuanke_centos7/git/blob/master/21NOSQL/1.php
执行脚本
/usr/local/php-fpm/bin/php 1.php
或者将1.php放到某个虚拟主机根目录下面，在浏览器访问，即可看到效果
最终可以看到数据如下：
[0] => aaa
[1] => bbb
[2] => ccc
[3] => ddd

　　memcached中存储session
本实例是在lamp/lnmp环境下实现
编辑php.ini添加两行
session.save_handler = memcache session.save_path = "tcp://192.168.0.9:11211" 
或者httpd.conf中对应的虚拟主机中添加
php_value session.save_handler "memcache" php_value session.save_path "tcp://192.168.0.9:11211" 
或者php-fpm.conf对应的pool中添加
php_value[session.save_handler] = memcache
php_value[session.save_path] = " tcp://192.168.0.9:11211 "

在php.ini文件下添加如下2行：

　　wget http://study.lishiming.net/.mem_se.txt
mv .mem_se.txt  /usr/local/apache2/htdocs/session.php
其中session.php内容可以参考https://coding.net/u/aminglinux/p/yuanke_centos7/git/blob/master/21NOSQL/session.php
curl localhost/session.php
