创建mysql登录用户及赋予权限

首先，先创建一个用户

CREATE USER 'admin'@'%' IDENTIFIED WITH mysql_native_password BY 'yourpass';

创建完后赋予相关权限

GRANT BACKUP_ADMIN,BINLOG_ADMIN,CONNECTION_ADMIN,ENCRYPTION_KEY_ADMIN,GROUP_REPLICATION_ADMIN,PERSIST_RO_VARIABLES_ADMIN,REPLICATION_SLAVE_ADMIN,RESOURCE_GROUP_ADMIN,RESOURCE_GROUP_USER,ROLE_ADMIN,SET_USER_ID,SYSTEM_VARIABLES_ADMIN,XA_RECOVER_ADMIN ON *.* TO `lisi`@`%` WITH GRANT OPTION;

GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, SHUTDOWN, PROCESS, FILE, REFERENCES, INDEX, ALTER, SHOW DATABASES, SUPER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER, CREATE TABLESPACE, CREATE ROLE, DROP ROLE ON *.* TO `lisi`@`%` WITH GRANT OPTION;

或

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'%' WITH GRANT OPTION;

最后刷新配置

flush privileges;
