Tested using 1.2.11 on Fedora37.

Removing the options allows the service to start.

Did you change the redis_version variable? The default is a very old version not supporting this param.

I do no longer have the playbooks around, but AFAIR I did change the version. I just took the defaults at first, but then tried a newer version and also got that error.

Anyway, updating the default version to something current would be a good idea, wouldn't it?

Solution

redis_install_from_source: true

because it install incorrect version of redis-server dpkg -l | grep redis ii redis 5:6.0.16-1ubuntu1 all Persistent key-value database with network interface (metapackage) ii redis-server 5:6.0.16-1ubuntu1 amd64 Persistent key-value database with network interface ii redis-tools 5:6.0.16-1ubuntu1 amd64 Persistent key-value database with network interface (client)

Issue still persists, looks like the earliest version to support this is 4.0-rc1, the commit is https://github.com/redis/redis/commit/edd4d555df57dc84265fdfb4ef59a4678832f6da I'll test if 4.0-rc1 still works with this repo. I would suggest simply updating the default redis version to 4.0-rc1, would this be a viable fix?
