Question

在我的CentOS云服务器上执行yum更新后，MySQL无法启动。

在网上搜索错误后：

Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

我试图通过find和grep搜索文件mysql.sock但没有成功。尝试以安全模式启动mysql后，mysql的错误日志是：

130529 13:51:18  InnoDB: Starting shutdown...
130529 13:51:23  InnoDB: Shutdown completed; log sequence number 0 43655

希望你们能帮助我，我可以提供你需要的任何信息，告诉我如何帮助你帮助我。

编辑：尝试用chwon文件为mysql和chmod。

在负面标记我之前，看看我写的是什么，我已经使用过MYSQL_UPGRADE而套接字的错误是一样的。

Answer 1

您的日志中有错误可以解释出现了什么问题。 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.表示您的mysql表架构已过期，需要升级。

MySQL服务器不会在百胜升级后启动
