redis bitcount example not working

[ahujamoh]

I was playing with redis and tried the bitcount example: http://redis.io/commands/bitcount
127.0.0.1:6379> SET mykey "foobar"
OK
127.0.0.1:6379> BITCOUNT mykey
(error) ERR unknown command 'BITCOUNT'
my redis version are as follows:

mohit@mohit:$ redis-server --version
Redis server v=3.0.1 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 build=ecf41ef76feca5d
mohit@mohit:$ redis-cli --version
redis-cli 3.0.1
I verified with the website, 3.0.1 is the latest stable version. What went wrong in this arrangement

The running instance you're connecting to is probably not version 3.0.1
Verify using the INFO server command.

redis_version:2.4.14
redis_git_sha1:00000000
redis_git_dirty:0
arch_bits:64
multiplexing_api:epoll
gcc_version:4.6.2
process_id:2433
uptime_in_seconds:9161122
uptime_in_days:106
lru_clock:561885
used_cpu_sys:765.5

I checked the version. It is 2.4.14, can you guide me of how to fix this?

redis_version:2.4.14

Upgrade your instance (that involves restarting it, so if this is a production instance carefully plan this)

I replied in the other side (Stack Overflow) and imagined this was the case... and asked for INFO indeed :-) Closed.
