Many configuration settings are present in application systems (such as Hadoop, MySQL, and Hive) that affect how well these systems function. To optimize these settings, however, is a difficult operation because there are hundreds of parameters, and the ideal parameters vary depending on the workload. Based on the openEuler operating system, we create the A-Tune automatic parameter tuning system to address these issues. According to the experimental findings, MySQL's performance increases by 30% to 40%.<br>
