@ranjeetranjan Could you please include the playbook which you used and the target distribution (Ubuntu, RedHat, etc.)?

[ranjeetranjan]

Its Centos -7

Here is my playbook.

• name: configure the master redis server
  hosts: redis-master
  roles:

  • DavidWittman.redis

• name: configure redis slaves
  hosts: redis-slave
  vars:

  • redis_slaveof: 272.14.43.44 6379
    roles:
  • DavidWittman.redis

• name: configure redis sentinel nodes
  hosts: redis-sentinel
  vars:

  • redis_sentinel_monitors:
    • name: master01
      host: redis-master
      port: 6379
      roles:
  • DavidWittman.redis

Also please see my host file

[redis-master]
272.14.43.44

[redis-slave]
272.14.43.45

[redis-sentinel]
272.14.43.46 redis_sentinel=True

@DavidWittman ,
Any suggestion for me?

[PhillipAmend]

@DavidWittman
I got the same Issue here. With the exact same errors.
OS is Ubuntu 16.04
Ansible is on 2.3.0.0

@DavidWittman
I have had the same issue as @PhillipAmend with Ubuntu 16.04. Is there a work around or fix for this issue?

At first sight, I would say that the value of host in redis_sentinel_monitors is wrong, it should be the IP (or fqdn) of the master redis server. In @ranjeetranjan's given configuration it's set to the ansible group name redis-master, which does not resolve to the actual master server.

But it should not fail to start..
