Hi,

I am trying to implement a PoC of Redis streams, but I am having an error when trying simple XADD command from redis-cli. Command line looks like this:

AMAC02VKKQ8HTD5:redis-5.0-rc1 dominika.hurajtova$ src/redis-cli

127.0.0.1:6379> XADD mystream * name Sara surname OConnor

(error) ERR unknown command 'XADD'

127.0.0.1:6379> set foo bar

OK

As you can see SET is working.

Can you please help me?

Thank you,

Dominika Hurajtova

Heelo Dominika,

You're probably running an older (than 5) version of redis-server - what does `info server` say?

Oh, yeah. You are right. Even though I removed old Redis and installed version 5, info-server still says redis 4.0.8. I'll dig into it.

Thank you! And sorry for bothering with such silly question.

It ain't silly - happens to me every time (so perhaps I'm a silly person ;))

Just send a `SHUTDOWN` to the Redis server (or sudo service redis_6379 stop, or similar) - then restart and it should be using the updated binary.
