I am setting up a memcached server in production, and would like the ability to switch between various memory sizes simply by changing out a symlink from one config to another, however I do not want to copy and paste every config into every other config, is it possible to have a master config with multiple child configs?
Example:
# master config
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="128"
OPTIONS=""
# Name: memcached_256
# child config for cache server of 256
# include options from master config
CACHESIZE="256"
# Name: memcached_512
# child config for cache server of 512
# include options from master config
CACHESIZE="512"
Example dir listing:
ls /etc/sysconfig
memcached -> /path/to/my/version/controlled/configs/memcached_256
And if I ever need to upgrade, I can simply change the above symlink to:
memcached -> /path/to/my/version/controlled/configs/memcached_512
Then after changing out the symlink, simply restart the service. Or if there is a better way to accomplish this functionality, that would be appreciated as well.
