尝试导入MySQL转储和/或者启动mysqld返回以下错误：

[ERROR] bdb:  fatal region error detected; run recovery
[ERROR] Fatal error: Can't open and lock privilege tables: Table 'host' is read only

可能是MySQL数据库目录没有正确的特权。
许可方案应如下所示：

MySQL directory = 755 own by mysql and group mysql
Database directory = 700 own by mysql and group mysql
Database directory tables = 660 own by mysql and group mysql
