PostImporting a large MySQL database from Linux Terminal

Ubuntu Terminal

Ubuntu Terminal

Let’s say you have a very large MySQL database and you are moving it to a new server ( or just moving your whole website to a new web host ) and of course your cannot import it from phpMyAdmin.

This is a tutorial to show you the easiest way to import a very large MySQL database from your shell/terminal. First of all you need to upload the MySQL backup the your server and go to that location:


cd /location/to/your/databasebackup.sql
mysql -u username -ppassword databasename < databasebackup.sql

The command is pretty easy to understand.

The -u parameter is the mysql user you use to connect to your MySQL server.
The -p parameter is the password for the MySQL user. In case your password has special characters ( like $%@&! ) you can enter the password between double quotes: -p"password%!$@#"

In case you need more explanations 🙂 the database name in the command is the name of the MySQL database you use and databasebackup.sql is the name of the file/SQL backup you want to import.

Another easy way is to use the mysql source command to import data:


cd /location/to/your/databasebackup.sql
mysql
use databasename;
source databasebackup.sql;
