想要将MySQL Datadir移动到另一个分区

Question

我想把我所有的mysql数据库移到另一个分区。我已经尝试过那些名副其实的指南，但我找不到任何有用的东西！

每当我更改my.cnf中的'datadir'时，MySQL就会停止运行！

$ mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

以下是更多信息：

$ mysqld -u root
101110 16:37:03 [Warning] Ignoring user change to 'root' because the user was set to 'mysql' earlier on the command line
101110 16:37:03 [Warning] Can't create test file /home/krainboltgreene/repo/databases/mysql/krainboltgreene-desktop-gateway.lower-test
101110 16:37:03 [Warning] Can't create test file /home/krainboltgreene/repo/databases/mysql/krainboltgreene-desktop-gateway.lower-test

这是conf文件：

正如@cdhowie所说，看起来你可能只需要将你的新目录chown到mysql。这通常通过sudo chown -R mysql:mysql directoryname

完成

如果有效，请告诉我们。
