All the redis configuration is saved inside a config file called redis.conf. In the network session of redis.conf file a user can find details about the port

2. Change the Redis port using CLI

A user can also change the port in redis by using the CLI command.

First, connect to redis cli using the below command

Now type the CONFIG SET command to change the redis port to 6479> CONFIG SET port 6479

Verify if the port gets changed> CONFIG GET port 6479
1) "port"
2) "6479"
change redis port

Now exit the redis cli and type the below command to connect to the redis port 6479> exit
root@f1322de9d190: redis-cli -h localhost -p 6479
