Basic memcache security

Since most clients are not aware of the security risk that memcache represents, there is one little fix that should be applied every time we install it for a client.

Once you have installed memcache, go to : /etc/sysconfig/ and edit the file called memcached.

In there find the OPTIONS="" line and make it : OPTIONS="-l 127.0.0.1" (that minus L).

Then restart memcached, /etc/init.d/memcached restart

This will prevent any one from the outside from connecting to memcached from outside.
