将mysql的data目录移走方法

如移动到"/home/mysql/data"，我的mysql是装在/usr/local/mysql下的

1. 将/usr/local/mysql/data移动到/home/mysql/data

mv /usr/local/mysql/data /home/mysql/data

2. 修改启动文件

vi /usr/local/mysql/support-files/mysql.server

修改如下行，指定datadir

datadir=/home/mysql/data

3. 修改配置文件

vi /etc/my.cnf

在[mysqld]下添加一行，指定datadir

datadir=/home/mysql/data

4. 重新启动mysql

/usr/local/mysql/support-files/mysql.server start
