由于缺少特权，MySQL Router 8.0.19引导失败

Question

在MySQL Router documentation之后，出现以下错误引导路由器。群集和路由器版本均为8.0.19。

Error: Error creating MySQL account for router (GRANTs stage): 
Error executing MySQL query "GRANT SELECT, EXECUTE ON mysql_innodb_cluster_metadata.* 
TO 'mysql_router5_vl2j3rlcnec9'@'%'": Access denied for user 'runtime'@'%' to database
'mysql_innodb_cluster_metadata' (1044)

似乎无法成功引导路由器，但是究竟是什么？

Answer 1

文档不完整：缺少 EXECUTE 特权以及对performance_schema.global_variables的 SELECT 特权。

GRANT SELECT, INSERT, UPDATE, DELETE, EXECUTE ON mysql_innodb_cluster_metadata.* TO
'bootstrapuser'@'%';

GRANT SELECT ON performance_schema.global_variables TO 'bootstrapuser'@'%';
