Mysql 迁移最完整可用的教程

此教程来源stackoverflow，仅供我自己需要时查看，其他人不可以瞎看！

## Stop MySQL using the following command:

`sudo /etc/init.d/mysql stop`

## Copy the existing data directory (default located in /var/lib/mysql) using the following command:

`sudo cp -R -p /var/lib/mysql /newpath`

## edit the MySQL configuration file with the following command:

`sudo gedit /etc/mysql/my.cnf`

##Look for the entry for datadir, and change the path (which should be /var/lib/mysql) to the new data directory.

In the terminal, enter the command:

`sudo gedit /etc/apparmor.d/usr.sbin.mysqld`

## Look for lines beginning with /var/lib/mysql. Change /var/lib/mysql in the lines with the new path.

Save and close the file.

## Restart the AppArmor profiles with the command:

`sudo /etc/init.d/apparmor reload`

## Restart MySQL with the command:

`sudo /etc/init.d/mysql restart`

Now login to MySQL and you can access the same databases you had before.
