How To Backup and Restore your Inventory Management System

There are two important sections of The Inventory Management System that need to be backup and/or restore.  The system stores images that are uploaded in a directory within the source-code.  Backup this directory or the entire application to a folder on your file system.

Example:

sudo cp -R /var/www/html/warehouse-inventory-system /home/pi/Downloads/

Backup and Restore Your Database

Export A Database

To Export a database, open up terminal, making sure that you are not logged into MySQL and type,

mysqldump -u [username] -p [database name] > [database name].sql

Backup your Inventory Management System

mysqldump -u'root' -p'password' oswa_inv > /path/to/oswa_inv.sql

The database that selected in the command will now be exported to a file.

Import

Log into mysql command-line interface:

mysql -u'username' -p'password'

WARNING!  You are about to permanently delete ALL of your data.

DROP DATABASE oswa_inv;
CREATE DATABASE oswa_inv;
source oswa_inv < /path/to/oswa_inv.sql

Exit mysql.

How to Reset Your Password

When you first install MySQL, you have to set up your root password. However, should you forget it at any point, you can still recover it.

Step One—Shut Down MySQL

In terminal, stop the MySQL process

 /etc/init.d/mysql stop

Step Two—Access MySQL Safe Mode

In safe mode, you will be able to make changes within the MySQL system with a root password alone, without the need for MySQL root password.

sudo mysqld_safe --skip-grant-tables &

Once safe mode has started up, log into MySQL and when prompted, use your standard root password.

mysql -u root mysql

Step Three—Set Up a New Password

Finally, set up the new MySQL root password by typing the command below. Replace “newpassword” with the password of your choice.

update user set password=PASSWORD("newpassword") where User='root';

Be sure to reload everything:

 FLUSH PRIVILEGES;

and you now have a new root password.
