如果遇到下述错误,表示当启动mysqld时或重新加载授权表时,在用户表中发现具有非法密码的账户。

  发现用户’some_user’@’some_host’密码错误:忽略用户。

  作为其结果,许可系统将简单忽略账户。

  在下面的介绍中,指明了可能的原因和问题的更正措施:

  1.或许,你正打算用旧的用户表运行新版本的mysqld。执行mysqlshow mysql user检查Password(密码)列是否短于16个字符,通过该方式可检查该问题。如果结果是肯定的,可运行脚本/add_long_password脚本更正该问题。

  2.账户具有旧的密码(8字符长),而且未使用“--old-protocol”选项启动mysqld。更新用户表中的账户,使之具有新的密码,或使用“--old-protocol”选项重启mysqld。

  3.在用户表中未使用PASSWORD()函数指定了密码。使用mysql用新密码更新用户表中的账户,务必使用PASSWORD()函数:

  4.

  mysql> update user SET Password=PASSWORD(’newpwd’)

  5.

  -> where User=’some_user’ AND Host=’some_host
