<h1 class="topictitle1">Why Does the Root User Not Have the Super Permissions?</h1>
|
|
<div id="body8662426"><p id="rds_faq_0075__a39094a2d184f42abaf2f7c27928bdb0d">Most relational database cloud service platforms do not provide super permissions for the <strong id="rds_faq_0075__b842352706102918">root</strong> user. The super permissions allow users to execute many management commands, such as reset master, set global, kill, and reset slave. These operations may cause primary/standby replication errors. This is a major difference between public cloud databases and on-premises MySQL databases. To ensure stable running of DB instances, RDS does not provide the super permission for the <strong id="rds_faq_0075__b720612237103623">root</strong> user.</p>
