mysql 8不再需要手工升级检查表?

The mysql_upgrade client is now deprecated. The actions executed by the upgrade client are now done by the server.

To upgrade, please start the new MySQL binary with the older data directory. Repairing user tables is done automatically. Restart is not required after upgrade.

The upgrade process automatically starts on running a new MySQL binary with an older data directory. To avoid accidental upgrades, please use the --upgrade=NONE option with the MySQL binary. The option --upgrade=FORCE is also provided to run the server upgrade sequence on demand.

It may be possible that the server upgrade fails due to a number of reasons. In that case, the upgrade sequence will run again during the next MySQL server start. If the server upgrade fails repeatedly, the server can be started with the --upgrade=MINIMAL option to start the server without executing the upgrade sequence, thus allowing users to manually rectify the problem.

现在不推荐使用mysql_upgrade客户端。 升级客户端执行的操作现在由服务器完成。

要升级，请使用旧数据目录启动新的MySQL二进制文件。 修复用户表是自动完成的。 升级后不需要重新启动。

升级过程在使用旧数据目录运行新的MySQL二进制文件时自动启动。 为避免意外升级，请使用--upgrade = NONE选项和MySQL二进制文件。 还提供了选项--upgrade = FORCE以按需运行服务器升级序列。

由于多种原因，服务器升级可能会失败。 在这种情况下，升级序列将在下一个MySQL服务器启动期间再次运行。 如果服务器升级重复失败，则可以使用--upgrade = MINIMAL选项启动服务器以启动服务器而不执行升级序列，从而允许用户手动纠正问题。
