Redhat – Launch memcached on server boot

I have previously used this for the same packages.. (EPEL)

rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

To search for correct packages try..

yum search geoip

Then simply installing should be as you already have been answered..

Note: when installing the EPEL.. accept the GPG key ( so you dont need to do it on every install)

How do I know that a package is a EPEL package????

All EPEL packages are signed with the EPEL gpg-key. The public key with id 217521F6 is part of the epel-release package; yum will ask you to import it the first time you install a EPEL package.

I use Ubuntu, and Debian mostly, so this answer is based on those, but I suspect the answer for other distros is largely the same.

In /etc/memcached.conf -- If it's not in exactly the same place, a) I'd be surprised, and b) you could find it with locate

# Start with a cap of 64 megs of memory. It's reasonable, and the daemon default
# Note that the daemon will grow to this size, but does not start out holding this much
# memory
-m 64

So all you need do, is change the -m 64 line to

-m 4096

Or similarly large value in Megabytes.

There's some other yummy tuning parameters in there, such as the user it runs as, and what to do when it runs out of memory, and the IP address to bind the daemon to.. Have a look for yourself.
