Backing up and Dumping Mysql Databases

dump a database into file using mysqldump

Replace <username>, <password> and <dbname> with your specific values:

mysqldump -u <username> -p<password> <dbname> > /tmp/dump.sql

use a dump created by mysqldump to populate a database

The dump created in the last step is just a series of sql statements that can be used to populate a database. If the dump has been created at /tmp/dump.sql, then we should do the following:

Log in to mysql. Replace <username>, <password> with your own.

mysql -u <username> -p<password>

once inside the mysql cli interface, select a database. Replace <dbname> with your database name.

use <dbname>;

then load the dump file into this database:

source /tmp/dump.sql;
