I am trying to connect to memcache as they suggest:

$memcache = new Memcache();
$memcache->pconnect('localhost',11211);

But i get:

Notice: Memcache::pconnect() [memcache.pconnect]: Server localhost (tcp 11211) failed with: Connection refused (111) in /home/user/public_html/website.com/includes/basedatos.php on line 26

Any idea why?

    That generally means memcache isn't running. Have you set it up?

    memcache is two parts: a client interface (the PHP version of which is installed via PECL or similar) and the actual memcache server daemon, which needs to be installed as a completely separate program or system package. What OS are you running on? If it's a debian-based flavor of Linux, try sudo apt-get install memcached

You need to actually install the memcached server so that it can be connected to. On CentOS, this can be done with...

sudo yum install memcached

(on debian flavors of linux, use apt-get instead of yum)

  • @ToniMichelCaubet - the syntax Amber provides is correct, read this. You may need to do some web-searching around the problem since we don't have access to try a few other things that would come to mind if we were at your console. Do some digging :).

  • (Also the fact that some distros have sane package repositories that actually include most of the things you might want in a basic server. cough)

  • i think this is incorrect isnt that so, because he is asking about Memcache and the given answer is for the "Memcached" two different things

  • @user1179459 memcached is the memcache server.

This may be obvious, but make sure that memcached is actually running:

service memcached start

  • For me, it was actually because it was running, but I had changed from the default port in /etc/memcached.conf

memcache is diffrent with memcached

and i thing you have installed memcache because $memcache = new Memcache(); worked

you must started it on your server

check this 10 baby steps to install Memcached Server and access it with PHP
