Memcached help needed

wrkalot · Post by **wrkalot** » Sun Oct 15, 2017 3:34 pm

I need some help getting memcached running.

I have the memcached.php file in phpbb/cache/driver directory

I changed this in config.php $acm_type = 'memcached';

All I get is a blank page after purging the cache from the ACP

My host used unix sockets and I have no idea how to get this running. When I enable memcached in cPanel I get the following

Code: Select all

Your Memcached instance is online and listening at /home/mysite/.hostdata/memcached.sock

Can anyone explain how to make this work?

You need to get the server error logs when this happens (ask your host to look into it). They will state where the problem is.

I'll do that but I would first like to know how to properly point to the unix socket /home/mysite/.hostdata/memcached.sock

They don't provide a host or port number and I can't find any instructions for setting it up phpbb3 using a unix socket

Sorry you're at the wrong site for that question. This is a forum for phpBB support not on how to configure a server.

Some kind soul may jump in and assist but I wouldn't expect it.

I'm not asking for help configuring a server. I am asking how to configure memcached within phpbb3 using phpbb3's memcached.php extension using unix sockets. Maybe that wasn't clear enough.

If you want to use unix sockets, you'll need to add these to your config.php:

Code: Select all

define('PHPBB_ACM_MEMCACHED_PORT', 0);
define('PHPBB_ACM_MEMCACHED_HOST', '/path/to/socket');

Thank you for your help. I actually put them in memcached.php and it seems to be working but will verify with my host.

Interestingly enough, the blank page was being caused by RMcGirr83 National Flags ext. Once that was disabled it worked as it should

Do you know why it was causing the issue (server error logs). That extension was just recently, yesterday, updated as there was a bug in it. But it would be nice to know.

The error log in cPanel doesn't show anything. See the link below

Memcached/Memcache is very tricky. I never managed to get it working on any of my sites despite considerable effort. I suggest Opcache, which should be standard on UNIX servers and very easy to use.

Great! Now how about answering the questions I asked within that topic.
