XAMPP MySQL 启动在 MacBook Air (MacOS Sierra 10.12.2) 上失败

Question

我昨天正在下载 XAMPP v7.0.13-0，我遇到了MySQL MariaDB 无法启动的问题，我不知道为什么它不会，我试图从“MacOS 终端”运行该应用程序。应用

sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

导致错误：

Warning: World-writable config file '/Applications/XAMPP/xamppfiles/etc/my.cnf' is ignored

XAMPP 的日志文件如下所示：

我不知道如何解决这个错误。我已经重新启动了几次操作系统，并确保没有实例已经在运行。

请帮忙！

我刚刚重新安装了XAMPP，现在日志有点不同：

回答：有一个 AppleDB 实例是 Apple 开发者版本（适用于 SierraOS）的默认设置，我联系了 Apple 支持，并被告知搜索 /private/dev/.adb/app.plist 并将其删除。

删除 plist 文件后，他们告诉我导航到 /private/.databases/ 并删除 .StartDBOnStartup。重新启动我的 mac 后，它工作了，并且不再使用该端口。

我不太确定它是什么实例，但无论如何它都没有显示在终端中。

终端上的命令很少。当你开始你的mamp时，你应该 查看错误消息。

查找 unix 命令。我认为它是 netstat 组合或管道，您可以称之为它。

我相信您可以在 mamp 控制面板中分配端口。有很多方法可以在 osx 上安装 mysql php 和 apache。

您可以使用 mamp。 您可以使用 macports 手动安装它们。

如果你刚刚购买了你的 macbook，你应该能够下载 xcode，我相信你应该能够安装 xcode，这将允许你使用 mac ports 命令行安装它们。

查看在线文档。只需按照说明进行操作，就可以了。

您是否安装了其他可能与 mysql 端口冲突的应用程序，例如 skype。您可以手动分配mysql端口。

尝试查看使用端口 3306 的内容。您需要找到该应用程序并将其卸载，然后才能有人抓住您的电脑并重新启动它。

这发生在我在亚马逊 AWS 上的服务器上。我花了数周时间修复它。这甚至发生在我朋友的电脑上。我相信他有他的大学朋友试图教他如何在没有任何经验的情况下安装灯组，我们花了数周时间修复它。

我认为你模糊了你的 innodb 表。您可能需要在备份后删除 /var/lib/mysql 表并尝试重新启动 mysql。

如果我是你，我会重新安装 osx 并从头开始。我以前做过，需要很长时间。

您应该压缩源表和备份表并在您的个人计算机上重新安装所有内容。
