我正在尝试在我的 apache 上使用 memcache。(Xubuntu 13.10)我在这里安装了 Apache 2.4、Php5、Mysql5、php pear 等: https ://www.digitalocean.com/community/articles/how-to-install-and-use-memcache-on-ubuntu-12 -04

root@benjamin:~# ps aux | grep memcached
www-data 16113 0.0 0.0 325400 916 ? Ssl 12:10 0:00 memcached -d -m 128 -l 127.0.0.1 -p 11211 -vv -u www-data
root 16178 0.0 0.0 18008 956 pts/1 S+ 12:16 0:00 grep --color=auto memcached
和我使用的示例 php 代码
<?php
$memcache = new Memcache;
$memcache->connect("localhost",11211); # You might need to set "localhost" to "127.0.0.1"
echo "Server's version: " . $memcache->getVersion() . "<br />\n";
$tmp_object = new stdClass;
/*
$tmp_object->str_attr = "test";
$tmp_object->int_attr = 123;
$memcache->set("key",$tmp_object,false,50);
*/
$stat = $memcache->getExtendedStats();
echo "Store data in the cache (data will expire in 10 seconds)<br />\n";
echo "<pre>";
print_r($stat);
echo "Data from the cache:<br />\n";
print_r($memcache->get("key"));
?>
问题是,什么都没有发生。完全白页。我怎样才能做到这一点?PS:我也尝试连接 127.0.0.1 而不是 localhost。
更新,我配置了 php.ini,我现在可以得到错误。
