MySQL 5.6 如何更改安全的处理密码探讨

MySQL 5.6将会自动的在日志中隐藏密码信息,接下来为你详细介绍下MySQL 5.6 如何更安全的处理密码,感兴趣的你可以参考下哈,希望可以帮助到你

MySQL 5.6 将会自动的在日志中隐藏密码信息。这不只是混淆,然后将单向哈希值存放在日志文件中。通过设定 log-raw=OFF 你可以禁用日志文件的密码隐藏功能。log-raw 设置只影响一般的日志,而慢查询日志和二进制日志中依然会对密码进行隐藏。

在 MySQL 5.5 中这个需要在首次将哈希存储在变量时手工处理。但多数场景下这已经没什么用处了。
但还不止这些,根据 mysql 命令的手册,mysql 命令将不会记录匹配到 "*IDENTIFIED*:*PASSWORD*" 的语句。

尽管如此,还是别忘记给 MySQL 服务器和客户端日志文件予以核实的权限保护,包括其他的一些如 master.info 的文件。此外,如果你在数据库中存储从节点的凭证时需要使用 MySQL 的特权系统进行保护,如果 master.info 使得某人具有太多的数据库权限,并可使用 LOAD DATA INFILE 加载内容时也应该这么做。

当然,这依然有改进的地方:
如果我们可以轻松的启用安全连接,这将更好。MySQL 和很多其他应用使用 TLS,但有一些性能的问题,而且设置起来不容易。此外 MySQL 默认是不安全的,只为简单。
因此 MySQL 5.6 在无需任何配置下还是对安全进行了提升。
