MYSQL 不会运行

Question

我在启动 MYSQL 时得到这个？

20:43:41  [mysql]   Error: MySQL shutdown unexpectedly.
20:43:41  [mysql]   This may be due to a blocked port, missing dependencies, 
20:43:41  [mysql]   improper privileges, a crash, or a shutdown by another method.
20:43:41  [mysql]   Press the Logs button to view error logs and check
20:43:41  [mysql]   the Windows Event Viewer for more clues
20:43:41  [mysql]   If you need more help, copy and post this
20:43:41  [mysql]   entire log window on the forums

有人可以帮帮我吗？ MYSQL 启动大约 5 秒钟然后关闭...我在任何地方都找不到修复，所以我决定在这里发布它，如果您可以修复，请不要犹豫发表评论。

Answer 1

你没有提供太多关于你是如何走到这一步的信息。从错误消息中可以清楚地看出，InnoDB 存储引擎代码无法创建必要的临时文件。

当我重新安装 MySQL 并尝试从即将退役的硬盘中移动我的 data 文件夹时，我遇到了类似的问题。这是一个目录保护问题。

不要做我第一次做的事情：尝试使用保护措施（chmod 等）。那里有疯狂——说真的。如果您已经这样做了，请卸载并重新安装 MySQL。

尝试在控制台模式下运行 mysqld 以了解发生了什么。此处记录了这一点。

http://dev.mysql.com/doc/refman/5.6/en/windows-start-command-line.html

注意，您可能应该使用具有管理权限的 cmd 提示符来执行此操作。启动 InnoDB 的问题可能是因为您试图在没有足够权限的情况下运行 mysqld。要使用管理权限启动命令提示符，请确保您使用管理员帐户登录，然后按照这些说明进行操作。 http://technet.microsoft.com/en-us/library/cc947813(v=ws.10).aspx

如果以这种方式运行mysqld 启动正常，您可以尝试--install将其作为Windows 服务。见这篇文章：http://dev.mysql.com/doc/refman/5.6/en/windows-start-service.html

它可能已经作为服务安装，在这种情况下，您尝试安装它会失败。如果发生这种情况，请先使用--remove，然后再使用--install。

接下来，要确保它作为服务运行，请尝试打开该服务（开始/运行 services.msc）。找到 MySQL 服务。尝试停止它并使用服务管理器启动它。如果启动成功，那就太好了。

最后，确保服务的启动类型为自动（或自动延迟...）。然后，重新启动您的 Windows 机器并确保 MySql 已启动。
