Uninstall Percona Server for MySQL

Prior to uninstalling, it is recommended to create a backup. Depending on the size of the data, you can choose to use Xtrabackup, mysqldump, or mydumper. Let’s begin by backing up the existing databases, excluding the system databases for now.

mysqldump --single-transaction --routines --triggers --set-gtid-purged=OFF --databases test > test.sql

Save user grants

pt-show-grants > grants.sql

Stop MySQL

systemctl stop mysql
systemctl status mysql
