Binding to localhost
By default, the Redis server doesn’t accept remote connections. You can connect to Redis only from 127.0.0.1 (localhost) – the machine where Redis is running.
If you are using a single server setup where the client connecting to the database is also running on the same host, you should not enable remote access. You can use its configuration file
bind 127.0.0.1 ::1
Verify redis is listening on all interfaces on port 6379. Run the following command:
ss -an | grep 6379
