Mac OS - Homebrew - Mysql 无法启动

Question

我已经在 Mac OS Sonoma 14.6.1 上通过自制程序重新安装了 Mysql，当我尝试运行时：

sudo mysql.server start

我收到以下错误消息：

我已经尝试从头开始重新安装3次了。我还尝试将 /usr/local/var/mysql 的所有权更改为 mysql:mysql 但这并没有解决问题。我还尝试在重新安装 mysql 之前删除文件夹 /usr/local/var/mysql 及其所有内容。

当我尝试跑步时：

sudo mysql.server start

使用我的 mysql 文件夹的旧内容（不是全新安装），我收到以下错误：

Answer 1

Homebrew 的常见警告部分中清楚地列出了说明。如果您的计算机上没有显示该信息，您需要找出原因。跑步

brew doctor

将是一个很好的起点。

如果它确实显示，而您只是懒得阅读它，则可以通过运行

brew info mysql

再次显示它；它会再次显示信息，无需重新安装。

您的情况：

1. 重置（或删除）您已更改所有权的所有文件和文件夹
2. 运行

   brew doctor

   并修复它所说的任何内容 - 你可能忘记了一些东西。
3. 做一个

   brew reinstall mysql

   只是为了确定
4. 阅读该命令的完整输出！
5. 正常启动mysql，例如运行

   brew services mysql start
