After writing some data to a redis server, I could read the data from a client. However, how can I find the data directory on the file system?

Within Redis, there are two different ways of persisting data to disk. One is a method called snapshotting that takes the data as it exists at one moment in time and writes it to disk. The other method is called AOF, or append—only file, and it works by copying incoming write commands to disk as they happen.
To start Redis client, open the terminal and type the command redis-cli. This will connect to your local server and now you can run any command. In the above example, we connect to Redis server running on the local machine and execute a command PING, that checks whether the server is running or not.
Redis is an In-Memory Database(IMDB) as it relies on main memory of computer for data storage while others use Disk Storage database mechanism. That is why Redis is faster than disk-optimized databases because disk access is slower than memory access.
Quickest method: use redis-cli.
redis-cli config get dir If you have authentication configured, you will need to pass that in using -a password Replacing "password" with your password.

Find your Redis configuration directory, probably /etc/redis. Then look in the config file called redis.conf and find the line that starts dir.
It will look similar to this:
dir /etc/redis/database This will do the job slowly but surely if you can't be bothered to look :-)
sudo find / -name "redis.conf" -exec grep "^dir" {} \; 2> /dev/null dir /etc/redis or if you want the config filename as well:
sudo find / -name "redis.conf" -exec grep -H "^dir" {} \; 2> /dev/null /private/etc/redis/redis.conf:dir /etc/redis Other possibilities you can check are whether Redis was started with a custom config file as its first parameter like this:
redis-server /path/to.custom/config-file or with the dir option set on the commandline like this:
redis-server dir /path/to/data Use
ps -aef | grep redis to look for these options.
