Homebrew MySQL 给出 Bootstrap 失败：5：输入/输出错误

Question

当我尝试运行brew services start mysql时，我收到错误：

Bootstrap failed: 5: Input/output error

有人告诉我，我的 Mac 上的 mysql 可能已更新（我使用的是 mysql 9.0.1、Sonoma 14.6.1、M1 MacBook Pro），数据库需要升级。但我不知道该怎么做。

在 mysql 更新后我需要运行一个命令来升级我的数据库吗？

我尝试停止、启动和重新启动 mysql。我还尝试删除符号链接并重新链接。

Answer 1

运行

brew info mysql

，在警告部分，有详细的迁移说明。

❯ brew info mysql
...
==> Caveats
Upgrading from MySQL <8.4 to MySQL >9.0 requires running MySQL 8.4 first:
 - brew services stop mysql
 - brew install [email protected]
 - brew services start [email protected]
 - brew services stop [email protected]
 - brew services start mysql

We've installed your MySQL database without a root password. To secure it run:
    mysql_secure_installation

MySQL is configured to only allow connections from localhost by default

To connect run:
    mysql -u root

To start mysql now and restart at login:
  brew services start mysql
Or, if you don't want/need a background service you can just run:
  /usr/local/opt/mysql/bin/mysqld_safe --datadir\=/usr/local/var/mysql

此次迁移后，如果mysql仍然无法启动，请检查

*.err

文件夹中的

$(brew --prefix)/var/mysql

日志文件。
