MySQL Error number: MY-013494; Symbol: ER_WARN_LOG_PRIVILEGE_CHECKS_USER_DOES_NOT_EXIST; SQLSTATE: H

文档解释

Error number: MY-013494; Symbol: ER_WARN_LOG_PRIVILEGE_CHECKS_USER_DOES_NOT_EXIST; SQLSTATE: HY000

Message: PRIVILEGE_CHECKS_USER for replication channel ‘%s’ was set to `%s`@`%s`, but this is not an existing user. Correct this before starting replication threads.

错误说明

ER_WARN_LOG_PRIVILEGE_CHECKS_USER_DOES_NOT_EXIST(MySQL错误码 013494)是MySQL中抛出的一种错误,由MySQL服务器引擎尝试检查某个指定用户的日志权限时,由于这个指定用户不存在,而导致的错误。

常见案例

此错误通常会发生在当MySQL客户端试图为另一个用户重新设置日志权限时。MySQL检查权限时,会查看指定的用户是否存在,如果不存在,就会抛出ER_WARN_LOG_PRIVILEGE_CHECKS_USER_DOES_NOT_EXIST错误。

解决方法

为了解决这个问题,开发人员可以采取一些措施来确保指定的用户存在,包括:

1、使用MySQL命令行客户端,首先检查指定用户是否存在,使用SHOW USERS命令即可检查并显示用户名列表;

2、如果指定的用户不存在,则可以使用CREATE USER命令来创建一个新的用户;

3、此外,还可以使用GRANT命令来给指定的用户赋予日志权限,也可以使用REVOKE命令来撤销指定的用户的权限;

4、同时,还可以在MySQL数据库中更新指定用户的记录,并调用FLUSH PRIVILEGES来重新加载权限文件。
