Below is the script example to backup mysql database in command line:-
$ mysqldump -h localhost -u username -p database_name > backup_db.sql
If your mysql database is very big, you might want to compress your sql file.
Just use the mysql backup command below and pipe the output to gzip,
then you will get the output as gzip file.
$ mysqldump -u username -h localhost -p database_name | gzip -9 > backup_db.sql.gz
If you want to extract the .gz file, use the command below:-
$ gunzip backup_db.sql.gz
Type the following command to import sql data file:
$ mysql -u username -p -h localhost DATA-BASE-NAME < data.sql
In this example, import 'data.sql' file into 'blog' database using vivek as username:
$ mysql -u vivek -p -h localhost blog < data.sql
If you have a dedicated database server, replace localhost hostname with with actual server name or IP address as follows:
$ mysql -u username -p -h 202.54.1.10 databasename < data.sql
OR use hostname such as mysql.cyberciti.biz
$ mysql -u username -p -h mysql.cyberciti.biz database-name < data.sql
If you do not know the database name or database name is included in sql dump you can try out something as follows:
$ mysql -u username -p -h 202.54.1.10 < data.sql
