mysql backup and restore

Hello,

I am newbie to mysql and want to clarify below on mysql backup and restore

What are the things needed to backup mysql and restore it like database name, username, password etc.

1)I have a database which need to be restored on different server so I used mysql dump command to backup the database by using username root and now during restoration on different server what is the username and password  I need to use.

2)If I have created a new empty database on new server so can I restore old database on this new database.

As you described it, the real data inside the database will now be transfered.
You now miss only one thing, the permission / user rights to the database (on the new server). This is best done manually on the new database server (create user, passwords, then assign it to the database you just restored).

It's easy to import and export, or move database around like this with phpmyadmin.  It's an easy upload of files to install and use.  

But if you're set on using the shell or the file is to big to do any different then you can restore the database like this:
You can either change directories to wherever the backup is located and type in the following:
mysql -u dbusername -p databasename < backupname.sql

Open in new window


Or if you do not want to change directories and you know the path to where the backup is located, type in the following:
mysql -u dbusername -p databasename < /path/to/backupname.sql

Open in new window


You will be prompted for the database password.

And here are the commands for backing it up.

Type in the following to create a backup in the current directory:
mysqldump --opt -Q -u dbusername -p databasename > backupname.sql

Open in new window


Or to create a backup in a separate directory (signified by /path/to/) type:
mysqldump --opt -Q -u dbusername -p databasename > /path/to/backupname.sql

Open in new window


You will be prompted for the database password.

Hi

When we backup database using php then during restore we need same username and database used for backup?

Depends on the server where you restore it (did anyone install it and added the same users/passwords/rights?)! If not, just use something as long as it's an admin account.
