--------------------

Moving MySQL from default folder to home folder or any disc space in Debian

If the MySQL service not stop then you most Stop the service of MySQL before doing anything

sudo service mysql stop

First we will create folders that we will used for MySQL, we most create 3 important folders like the following:

mkdir /home/sources/var/lib/mysql

mkdir /home/sources/var/lib/mysql-files

mkdir /home/sources/var/log/mysql

mkdir /home/sources/tmp/mysql

Next we will copy the MySQL files from the source folder `/var/lib` to our created folder.

Note: don't remove the source folders after you finish the steps

cp -rap /var/lib/mysql /home/sources/var/lib

cp -rap /var/lib/mysql-files /home/sources/var/lib

cp -rap /var/log/mysql /home/sources/var/log

cp -rap /var/lib/mysql/mysql /home/sources/tmp/mysql

Then in MySQL config file we will change the following:

[mysqld]

pid-file    = /var/run/mysqld/mysqld.pid

socket      = /var/run/mysqld/mysqld.sock

datadir     = /home/sources/var/mysql

log-error   = /home/sources/var/log/error.log

Finally restart MySQL service and enjoy ^_^.

systemctl daemon-reload

service mysql restart
