How to compare the master-slave database in Mysql? I believe many inexperienced people don't know what to do about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

From the library configuration:

Report-host=192.168.3.70

Report-port = 3306

Master library comparison: specify slave library

Pt-table-checksum-user=root-password=123456-host=192.168.3.70-databases=drama

Diffs cannot be detected because no slaves were found. Please read the-- recursion-method documentation for information.

03-18T10:56:16 00 0 10 0.004 drama.webmodule_role

DIFFS: it stands for inconsistency. Consensus is 0.

Or

On the primary library, specify the primary library (--host=192.168.3.22)

Pt-table-checksum-user=root-password=qC0QKFiX-host=172.28.3.22-databases=drama-no-check-binlog-format
