Memcache函数库是在PECL(PHP Extension Community Library)中,主要作用是搭建大容量的内存数据的

临时存放区域,在分布式的时候作用体现的非常明显,否则不建议使用。 本人在ubuntu上安装

完运行的时候报错:
/usr/local/memcached/bin/memcached: error while loading shared libraries: libevent-1.4.so.2: 

cannot open shared object file: No such file or directory

按照:《libeven、memcached、libmemcache安装》中的方法,使用:

sudo ln -s /usr/local/lib/libevent-1.4.so.2 /usr/lib/libevent-1.4.so.2
可以修正这个BUG

通过新得立安装php的memcached模块,注销/etc/php5/conf.d/memcached.ini里面的“;”,重启apache

,调用phpinfo()出现memcached的信息

执行:
$memcache = new Memcache;
$memcache->connect(localhost11211) or die ("Could not connect"
);
$version $memcache->getVersion
();
echo 
"Servers version: ".$version.
"
"
;
?>
$memcache = new Memcache;
$memcache->connect(localhost11211) or die ("Could not connect"
);
print_r($memcache->getStats
());
/**
