Sorry redis newbie here.
When I run redis-sentinel
42533:X 10 Nov 21:21:30.345 # Warning: no config file specified, using
the default config. In order to specify a config file use redis-
sentinel /path/to/sentinel.conf
42533:X 10 Nov 21:21:30.346 * Increased maximum number of open files to
10032 (it was originally set to 7168).
Redis 3.0.4 (00000000/0) 64 bit
Running in sentinel mode

42533:X 10 Nov 21:21:30.347 # Sentinel started without a config file.
Exiting...
What am I missing? Do I need a configuration file? If so where should my /path/to/sentinel.conf be?
It is mandatory to use a configuration file when running Sentinel, as this file will be used by the system in order to save the current state that will be reloaded in case of restarts. Sentinel will simply refuse to start if no configuration file is given or if the configuration file path is not writable.
you can run Sentinel with the following command line:
redis-sentinel /path/to/sentinel.conf
Otherwise you can use directly the redis-server executable starting it in Sentinel mode:
redis-server /path/to/sentinel.conf --sentinel
You can put the file anywhere you want, just make sure you are providing the right path for that. For example, if you are in linux and if the file is inside your home directory, then the command will be
redis-sentinel ~/sentinel.conf
