Redis 4.x Cookbook

How to do it...

Let's discuss how to secure Redis with proper network configuration. It is never advisable to expose a Redis production server to the internet, where any untrusted client can access it. Therefore, it is imperative to configure Redis to bind to an IP address that is part of a trusted network:

1. To update the binding IP address and port, set bind and port in the configuration file:

bind 127.0.0.1 192.168.0.31
port 36379

2. Don't forget to update the corresponding settings in Replica and Sentinel's configuration:

#Replica's configuration (redis.conf) 
slaveof 192.168.0.31 36379 
 
#Sentinel's configuration (sentinel.conf) 
sentinel monitor mymaster 192.168.0.31 36379 

We can also configure Redis to stop listening to any network interface ...
