This tutorial shows multiple ways to How check Redis Server Version.

How to Check Redis installed version.

Open terminal, Type redis-server --version or redis-server -v in the command line.

A:\Java\Redis>redis-server --version
Redis server v=5.0.14.1 sha=ec77f72d:0 malloc=jemalloc-5.2.1-redis bits=64 build=5627b8177c9289c

A:\Java\Redis>redis-server -v
Redis server v=5.0.14.1 sha=ec77f72d:0 malloc=jemalloc-5.2.1-redis bits=64 build=5627b8177c9289c

You can also check with the redis-cli command.

Type redis-cli -v to get redis cli installed version

A:\Java\Redis>redis-cli -v
redis-cli 5.0.14.1 (git:ec77f72d)

It will not give server details.

Let’s see how to get Redis server information

First type redis-cli in the command prompt.

It changed to CLI mode. Type INFO to get the complete server, Memory, Persistence, Replication, Cluster information of the Redis server

Also, if you don’t want complete server information, run the below command to get the only installed version

redis-cli info server | grep ^redis_version
