Note: It’s important that you BACKUP your database first before performing the steps below.
Login to your cPanel Account
Create a new Database with the cPanel MySql Wizard
Select the “phpMyAdmin” icon
Select the database you wish to copy from the list in the left-hand sidebar
Select the “Operations” tab
Scroll down to “Copy database to:”.
Enter the new database name using the cpanel name format (with the username_ prefixed) and select “structure and data” to copy everything.
Check the box “Add AUTO_INCREMENT value.”
Click on the Go button to proceed.
You should now see your duplicated database in the list within the left-hand sidebar.
If you are not running cPanel then you can simply use the command prompt , see below:
MySQL Database – How To Copy a MySQL Database
Copy a MySQL database on the same server
To copy a MySQL database, you need to follow these steps:
- First, create a new database using
CREATE DATABASEstatement. - Second, export all the database objects and data of the database from which you want to copy using
mysqldumptool. - Third, import the SQL dump file into the new database.
For the demonstration, we will copy the classicmodels database to classicmodels_backup database.
Step 1. Create the classmodels_backup database:
First, log in to MySQL database server:
>mysql -u root -p
Enter password: **********
Then, use CREATE DATABASE statement as follows:
> CREATE DATABASE classicmodels_backup;
Third, use SHOW DATABASES command to verify:
> SHOW DATABASES
MySQL database server returns the following output:
+----------------------+
| Database |
+----------------------+
| classicmodels |
| classicmodels_backup |
| information_schema |
| mysql |
| performance_schema |
| sys |
+----------------------+
6 rows in set (0.00 sec)
As you see, we have created the classicmodels_backup database successfully.
Step 2. Dump database objects and data into SQL file using the mysqldump tool.
Suppose, you want to dump the database objects and data of the classicmodels database into an SQL file located at D:\db folder, here is the command:
>mysqldump -u root -p classicmodels > d:\db\classicmodels.sql
Enter password: **********
Basically, this command instructs mysqldump to log in to the MySQL server using the root user account with a password and exports the database objects and data of the classicmodels database to d:\db\classicmodels.sql. Note that the operator (>) means exporting.
Step 3. Import the d:\db\classicmodels.sql file into classicmodels_backup database.
>mysql -u root -p classicmodels_backup < d:\db\classicmodels.sql
Enter password: **********
Note that the operator ( <) means importing.
To verify the import, you can perform a quick check by using the SHOW TABLES command.
> SHOW TABLES FROM classicmodels_backup;
It returned the following output:
+--------------------------------+
| Tables_in_classicmodels_backup |
+--------------------------------+
| customers |
| employees |
| offices |
| orderdetails |
| orders |
| payments |
| productlines |
| products |
+--------------------------------+
8 rows in set (0.01 sec)
As you see, we have successfully copied all the objects and data from the classicmodels database to classicmodels_backup database.
Copy a MySQL database from a server to another
To copy a MySQL database from a server to another, you use the following steps:
- Export the database on the source server to a SQL dump file.
- Copy the SQL dump file to the destination server
- Import the SQL dump file to the destination server
Let’s take a look at how to copy the classicmodels database from a server to another.
First, export the classicmodels database to db.sql file.
>mysqldump -u root -p --databases classicmodels > d:\db\db.sql
Enter password: **********
Note that --database option allows mysqldump to include both CREATE DATABASE and USE statements in the SQL dump file. These statements will create the classicmodels database in the destination server and make the new database as the default database for loading the data.
In short, the following statements are included at the beginning of the SQL dump file when we use --database option.
CREATE DATABASE `classicmodels`.
USE `classicmodels`;
Third, import the db.sql file to the database server with the assumption that the db.sql file was copied to c:\tmp\ folder.
>mysql -u root -p classicmodels < c:\tmp\db.sql
In this tutorial, you have learned step by step how to copy a MySQL database on the same server and copy database from a server to another.
