I dont know if the starters script exist, but i cant found.
This is my solution from debian starters script in my Centos5.

Create the configuration file

Code:

touch /etc/memcached.conf

And put in:

Code:

#Memory a usar
-m 16
# default port
-p 11211
# user to run daemon nobody/apache/www-data
-u nobody
# only listen locally
-l 127.0.0.1

Create the startups files

Code:

touch /etc/init.d/memcached
chmod +x /etc/init.d/memcached

Edit with your favorite editor and paste this code

Code:

 
#!/bin/bash
#
# memcached    This shell script takes care of starting and stopping
#              standalone memcached.
#
# chkconfig: - 80 12

#              object caching system, generic in nature, but
#              intended for use in speeding up dynamic web
#              applications by alleviating database load.

Test the scripts

Code:

 
[root@srv01 init.d]# /etc/init.d/memcached restart
Shutting down memcached:                                   [  OK  ]
Starting memcached:                                        [  OK  ]

Review if the conf file is well parsed

Code:

[root@srv01 init.d]# ps aux  | grep memcached
nobody    5966  0.5  0.3 18248 16444 pts/0   S    13:55   0:00 /usr/local/bin/memcached -u root -m 16 -p 11211 -u nobody -l 127.0.0.1

Add memcached as autostart daemon

Code:

 
[root@srv01 init.d]# /sbin/chkconfig memcached on
[root@srv01 init.d]# /sbin/chkconfig --list | grep memcached
memcached       0:off   1:off   2:on    3:on    4:on    5:on    6:off
