  问:由于Linux服务器原有硬盘剩余空间不足,后来添加了新的硬盘并挂上了,想问怎么更改MySQL目录?

  答:

  首先停止MySQL服务,然后用mv命令将MySQL目录移动到新目录(为保险起见可以使用cp命令复制),再设置相同的权限。有两种方式完成MySQL目录更改最后的操作。

  第一种方式就是使用链接,用“ln –s 新目录 原MySQL目录”命令将新目录链接到原目录位置(如果之前使用的是cp命令,须先删除原MySQL目录后再建立链接)。

  第二种方式就是修改配置文件my.cnf,指定datadir和socket的值到新目录。对于服务器而言,,最好的方式是使用逻辑卷管理(LVM),就不需要更改目录了,只需要在添加新硬盘后增加MySQL目录所在逻辑卷大小就行了。
