I have a MySQL 8.0.27 InnoDB cluster running on three Ubuntu 20.04 servers. Everything's working fine, but when MySQL starts I get these warnings in MySQL's error log:
2021-12-07T21:26:47.858979Z 2 [Warning] [MY-011735] [Repl] Plugin group_replication reported: '[GCS] Automatically adding IPv4 localhost address to the allowlist. It is mandatory that it is added.'
2021-12-07T21:26:47.859017Z 2 [Warning] [MY-011735] [Repl] Plugin group_replication reported: '[GCS] Automatically adding IPv6 localhost address to the allowlist. It is mandatory that it is added.'
I believe that this relates to group_replication_ip_allowlist in MySQL. It's definitely getting read (I can break replication by putting the wrong values in) but I can't suppress these warnings. For example, I was hoping that:
group_replication_ip_allowlist = 127.0.0.1,192.168.1.0/24
would stop the IPv4 warning. What am I missing?
