Setup Multi Instance Memcache

Setting Up a Multi Instance Memcached Configuration

Lets first get the basic memcached instance installed

yum install memcached

Now lets create home for the memcached instance files

mkdir /etc/memcached-multi

Now lets create to instances the default 11211 and 11212 ports

vim memcached_11211

And add the following to the memcached_11211

PORT="11211"
USER="memcached"
MAXCONN="1028"
CACHESIZE="64"
OPTIONS=""

Then copy that to memcached_11212 file

cat memcached_11211 > memcached_11212

Edit the new file

vim memcached_11212

Change the file to following, adjusting the port

PORT="11212"
USER="memcached"
MAXCONN="1028"
CACHESIZE="64"
OPTIONS=""

Now download the new start up file

cd /etc/init.d/

mv memcache-multi.txt memcache-multi
chmod +x memcache-multi
