With systemd it will be as easy as creating additional unit files ( one for each memcached instance) with its corresponding config file. That should allow to stop / start / restart each memcache instance individually while also being systemd compliant. Examples: ## first instance ## # /usr/lib/systemd/system/memcached.service [Unit] Description=Memcached Before=httpd.service After=network.target [Service] Type=simple EnvironmentFile=-/etc/sysconfig/memcached ExecStart=/usr/bin/memcached -u $USER -p $PORT -m $CACHESIZE -c $MAXCONN $OPTIONS # /etc/sysconfig/memcached PORT="11211" USER="memcached" MAXCONN="1024" CACHESIZE="64" OPTIONS="" ## end first instance ## second instance ## ## second instance ## # /usr/lib/systemd/system/memcached-11214.service [Unit] Description=Memcached-11214 Before=httpd.service After=network.target [Service] Type=simple EnvironmentFile=-/etc/sysconfig/memcached-11214 ExecStart=/usr/bin/memcached -u $USER -p $PORT -m $CACHESIZE -c $MAXCONN $OPTIONS # /etc/sysconfig/memcached-11214 PORT="11214" USER="memcached" MAXCONN="1024" CACHESIZE="64" OPTIONS="" ## end second instance Lastly enable each service if not already enabled: # instance 1 systemctl enable /usr/lib/systemd/system/memcached.service systemctl start memcached.service # instance 2 systemctl enable /usr/lib/systemd/system/memcached-11214.service systemctl start memcached-11214.service You can also still use legacy sysv init scripts as there is support for backwards compatibility however the systemd approach is much simpler while adhering to the systemd standard. Good luck.
