How to change Memcached allocated memory size ?

To increase or decrease Memcached server's allocated memory size, you will need to edit /etc/init.d/memcached start up file's MEMSIZE=8 variable. The variable assigns memory in MegaBytes (MB), so MEMSIZE=8 is equal to 8MB. If you want to allocate 256MB to Memcached server(s), then edit and change variable to MEMSIZE=256 and then restart memcached server:

  service memcached restart

or via command shortcut

  memcachedrestart

If memcachedrestart shortcut doesn't work, you can re-add it via these 3 commands to be run within SSH telnet as root user:

 echo "service memcached stop" >/usr/bin/memcachedstop ; chmod 700 /usr/bin/memcachedstop
 echo "service memcached start" >/usr/bin/memcachedstart ; chmod 700 /usr/bin/memcachedstart
 echo "service memcached restart" >/usr/bin/memcachedrestart ; chmod 700 /usr/bin/memcachedrestart
