Just to verify, have you tried logging into Koha since you enabled memcached? Koha won't actually store anything in memcached until it has to. 2015-05-04 15:25 GMT-06:00 Larry Letelier <larry@opengeek.cl>:

Hi all,

Not much on enabling memcached for Koha 3.18.06 (Ubuntu 14.04 LTS 64-bit VPS), so I'm posting here for the community. It looks like I successfully installed memcached on localhost 11211. But it doesn't look like Koha appears as an entry when I run $ memcdump --servers localhost. Here's what I did:

1. Installed memcached

sudo apt-get install memcached

2. Navigated to /etc/koha/koha-sites.conf and changed MEMCACHED environment variable to 'yes' from 'no'

3. Restarted apache

service apache2 restart

4. Telnetted localhost at port 11211

telnet localhost 11211

and was able to successfully connect.

5. I then installed libmemcached-tools to test

sudo apt-get install libmemcached-tools

6. I then checked to see if my Koha instance appeared as a memcached entry (according to http://wiki.koha-community.org/wiki/Troubleshooting_memcached)

memcdump --servers localhost

7. But, nothing gets returned. Only a new, blank command line.

Any thoughts on why Koha is not showing up after running #6?

Many thanks!

Yes! You need to set the relevant variables on the instance's apache virtualhosts configuration file. You are welcome! Thank you for clarifying Tomas. Your suggestion worked. So in all, the steps I took were: 1. Install memcached (sudo apt-get install memcached) 2. Navigated to /etc/koha/koha-sites.conf and changed MEMCACHED environment variable to 'yes' from 'no' 3. Restarted Apache (service apache2 restart) 4. Check memcached server connection (telnet localhost 11211) - Successful 5. Installed libmemcached-tools to test if koha is memcached at this point (sudo apt-get install libmemcached-tools) - Unsuccessful 6. Navigated to /etc/apache2/sites-available/library.conf and added the memcached server <IP:Port> and a memcached name (in my case: 127.0.0.1:11211 and koha_library) 7. Restarted Apache (service apache2 restart) 8. Ran memcdump to test if instance is memcached (memcdump --servers localhost) 9. Output is as follows: root@vps43351:~# memcdump --servers localhost koha_libraryismemcached koha_library569c3d3a6db71bb72dedcf5be25e27fe koha_library095f4ee0d58b7919fb213439ad1a531d koha_library9e4a3f110dd37561d60ae982a38f274d koha_librarykohaconf Thanks for the help all. You guys are great. Best, Craig Butosi, MA, MLIS, B Mus (Hons.)

Good

Wrong. Explanation: that configuration variable controls wether memcached is enabled on each created instance, ON CREATION TIME. So already created instances won't use memcached unless you explicitly created it using the --use-memcached option switch.
