如何停止 OSX MySQL 填充错误日志

Question

我注意到大约每一秒，mysqld 错误日志中都有一个新行，指出登录失败。用户并不总是相同的，但是当 mysqld 运行时，它总是每秒发生一次。我想关闭此行为或阻止它记录。我怀疑这与launchd / launchctl 有关系。

建议？？

例如

[这个问题已经快一年了，但无论如何我只是在调查同一问题时遇到它，虽然答案可能不再与您相关，但可能适合其他人阅读。]

使用标准 MySQL 安装（包括 MySQL 首选项窗格）时可能会发生这种情况。当打开 MySQL 首选项窗格时，它会定期（大约每秒一次）尝试连接到 localhost，大概是为了找出 MySQL 是否正在运行并相应地显示状态。有趣的是，这些连接在返回系统偏好设置开始屏幕时不会停止，但在关闭系统偏好设置时会停止。

启动这些连接时，首选项窗格使用各种用户名（无论出于何种原因）。在我的MacOS塞拉利昂与MySQL 5.7.17，我观察到_spotlight，_mysql和当前用户的用户名。

但是，如果您在系统偏好设置关闭时获得了这些日志条目，则在您的情况下这是一个不同的问题。
