[Koha] Enabling Memcached on Koha 3.18.06

[Craig Butosi]

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 at vps43351:~# memcdump --servers localhost
koha_libraryismemcached
koha_library569c3d3a6db71bb72dedcf5be25e27fe
koha_library095f4ee0d58b7919fb213439ad1a531d
koha_library9e4a3f110dd37561d60ae982a38f274d
koha_librarykohaconf

Thanks for the help all. You guys are great.

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.

Yes! You need to set the relevant variables on the instance's apache virtualhosts configuration file.
