XenForo memcached setup how to use it?

[Garry]

Hi,

Just setting up my XenForo and would like to use memcached, by default it uses a port, but I understand you use a socket setup.
Anyway how do I config XenForo to work with Socket, instead of port?

PS. I didn't want to post in the phpBB3 post as it could be seen as being rude.

I haven't tested this but I'd imagine this post here is still valid.

Usually you can point to a socket using the unix:// method as noted above. Please let me know if this works!

It isn't working, I am running PHP 7.1, with memcached ticket in the settings, I have also started Memcached via cPanel.

XenForo is say:
Zend_Cache_Exception: The memcache extension must be loaded for using this backend ! - library/Zend/Cache.php:209

This is the XenForo setup I have in the config.php file

$config['cache']['backend'] = 'Memcached';
$config['cache']['backendOptions'] = array(
    'compression' => false,
    'servers' => array(
        array(
            'host' => 'unix:///home/XXXXXX/.hostdata/memcached.sock',
            'port' => 0,
        )
    )
);

I have also tried the host as

unix:///var/memcached/memcached.socket

The problem is it is utilizing the memcache extension which is only available until PHP 5.6.  I'd suggest contacting Xenforo and seeing if there is a way for it to utilize the memcached extension which would be necessary if you're running PHP 7.1.

I was running this on a VPS and had it working with PHP 7.1 using port, with memcached.
There is a guide on cPanel site: https://forums.cpanel.net/threads/installing-memcache-and-memcached-with-easyapache4.566261/#post-2414091

Post 8, using a pecl module

Not sure if this something you would setup on a shared hosting, so just putting it out there, just incase.

Looking at that guide they are installing the memcache extension not the memcached extension.  Unfortunately I don't foresee us offering it as an option after PHP 5.6 just due to the fact it was last updated in 2013: https://pecl.php.net/package/memcache  .  I don't foresee us offering the memcache extension in PHP 7.0 or 7.1 simply because even our vendors (cPanel, CloudLinux) are not doing it.

Thanks for the reply.
I think I have sorted it, by using libmemcached, instead.
Could you check to see in the logs if it working am on ams201 - overclan?

$config['cache']['backend'] = 'Libmemcached';
$config['cache']['backendOptions'] = array(
    'compression' => false,
    'servers' => array(
        array(
            'host' => '/home/USERNAME/.hostdata/memcached.sock',
            'port' => 0,
        )
    )
);

Looks like a similar solution to phpbb where they refer to the php memcached extension as Libmemcached.  As for checking if it's working you'd be best to open a ticket.  Although for most applications if it's not working they typically end up hanging or throwing an error.
