Next we need to uncompress the file and rename it to 'dragonfly'

tar zxf {file_name}
mv {file_name} dragonfly

Run Dragonfly​

Run the following command to run Dragonfly.

./dragonfly --logtostderr

Run Dragonfly with parameters​

The list of supported flags for Dragonfly can be seen by running “--help” option.

The full list of options can be seen by running “--helpfull” option.

The most useful options can be found here.

For example to run dragonfly with:

  • Log message at standard error
  • Password (set to youshallnotpass)
  • Cache mode enabled
  • Number of db set to 1
  • Listen on port 6379 and local host traffic only
  • Persist data at 30 minutes intervals
  • Max memory set to 12GB
  • The number of keys that the “KEY” commands return (set to 12288)
  • Set the dump file name (to dump.db)

You would run:

dragonfly --logtostderr --requirepass=youshallnotpass --cache_mode=true -dbnum 1 --bind localhost --port 6379  --save_schedule "*:30" --maxmemory=12gb --keys_output_limit=12288 --dbfilename dump.rdb

Flag files​

Flags can be also provided from a configuration file with the --flagfile <filename> flag. The file should list one flag per line, with equal signs instead of spaces for key-value flags.
