Php memcache (Classic php cache)

The Memcache function Library is used in the PECL (PHP Extension Community Library) to build large-capacity memory data.

The temporary storage area plays an obvious role in the distributed mode. Otherwise, it is not recommended. I installed it on ubuntu.

When running, an error is reported:
/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

Follow the methods in libeven, memcached, and libmemcache installation to use:

Sudo ln-s/usr/local/lib/libevent-1.4.so.2/usr/lib/libevent-1.4.so.2
This BUG can be fixed.

Run the new php memcached module to log out ";" in/etc/php5/conf. d/memcached. ini and restart apache.

, Call phpinfo () to display memcached information.

Run:
<? Php
$ Memcache = new Memcache;
$ Memcache-> connect (localhost, 11211) or die ("cocould not connect ");
$ Version = $ memcache-> getVersion ();
Echo "Servers version:". $ version ."
";
?>
<? Php
$ Memcache = new Memcache;
$ Memcache-> connect (localhost, 11211) or die ("cocould not connect ");
Print_r ($ memcache-> getStats ());
