Memcache function library is in pecl (PHP Extension Community Library), the main role is to build large-capacity memory data
Temporary storage area, in the distribution of the effect is very obvious, otherwise it is not recommended. I installed on Ubuntu
When you finish running the error:
/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
According to: "Libeven, memcached, Libmemcache Installation" method, using:
sudo ln-s/usr/local/lib/libevent-1.4.so.2/usr/lib/libevent-1.4.so.2
Can fix this bug
With the new memcached module that installs PHP, unregister the ";" in/etc/php5/conf.d/memcached.ini and restart Apache
, call Phpinfo () to appear memcached information
Perform:
$memcache = new Memcache ;
$memcache - Connect ( localhost , 11211 ) or Die ( "Could not Connect" );
$version = $memcache - getversion ();
Echo "Servers version:" . $version . "
" ;
?>
$memcache = new Memcache ;
$memcache - Connect ( localhost , 11211 ) or Die ( "Could not Connect" );
Print_r ( $memcache - GetStats ());
