MariaDBwarningreplicationhigh confidence
Slave is not supported in this build
Production Risk
Medium — replication proceeds without encryption; data in transit is unprotected.
What this means
SSL parameters were supplied to CHANGE MASTER TO but this MySQL binary was not compiled with SSL support, so the parameters are ignored.
Why it happens
- 1Using a non-SSL build of MySQL
- 2Providing MASTER_SSL=1 on a build without OpenSSL
How to reproduce
trigger — this will error
trigger — this will error
