memcached
tar xzf memcached-1.4.5.tar.gz
cd memcached-1.4.5
./configure -with-libevent=/usr       （注意libevent的路径要正确，遇到异常erro，有必要就使用sudo 来执行）
make
make install
# ls -al /usr/local/bin/mem*
-rwxr-xr-x 1 root root 137986 11?? 12 17:39 /usr/local/bin/memcached
-rwxr-xr-x 1 root root 140179 11?? 12 17:39 /usr/local/bin/memcached-debug
　　
　　start memcached  
　　memcached -m 10 -p 12000
　　
# /usr/local/bin/memcached -d -m 1024 -u root -l 172.22.10.252 -p 12000 -c 256 -P /memcached/memcached.pid


　　
2.Python-memcached安装
　　到http://www.cnblogs.com/chenli0513/admin/ftp://ftp.tummy.com/pub/python-memcached/下载最新版本的API，并解压tar包
　　输入python setup.py install命令进行安装
　　
　　3.小例子演示
　　将memcached.pyc拷贝到工作目录

01.#!/usr/bin/env python   
02.   
03.import memcache   
04.   
05.mc = memcache.Client(['127.0.0.1:12000'],debug=0)   
06.mc.set("foo","bar")   
07.value = mc.get("foo")   
08.print value  
　　

>>> import memcache
>>> mc=memcach.Clietn(['127.0.0.1:12111'],debug=0)
