pt-table-checksum - SQL Permossions

[Elazar_Gur]

Hi,

I’m using pt-table-checksum in my environment, with the same SQL user to run the tool (with this command):

pt-table-checksum --ignore-databases mysql h=$masterHost,P=$masterPort,u=$slaveUser,p=$slavePass

What is the minimum but necessary Permission that the SQL user needs to run it?

Thanks!

You need the following privileges for the pt-table-checksum mysql user:

mysql-master> GRANT REPLICATION SLAVE,PROCESS,SUPER, SELECT ON . TO checksum_user@’%’ IDENTIFIED BY ‘checksum_password’;
mysql-master> GRANT ALL PRIVILEGES ON percona.* TO checksum_user@’%’;
