Commands for Restoring and Backing Up MySQL Database on Linux

To back up and restore a MySQL database on Linux, you can use the mysqldump and mysql commands. Here are the detailed steps:

Backup Database

1. Use the mysqldump command:

To back up a database, you can use the mysqldump command. The basic syntax is as follows:

mysqldump -u [username] -p [database_name] > [backup_file.sql] 

   - [username]: The MySQL username.
   - [database_name]: The name of the database you want to back up.
   - [backup_file.sql]:The name of the file where you want to save the backup.

Example:

mysqldump -u root -p mydatabase > mydatabase_backup.sql

After entering the command, you will be prompted to enter the password for the MySQL account.

Restore Database

1. Use the mysql command::

To restore a database from a backup file, you can use the mysql command. The basic syntax is as follows:

mysql -u [username] -p [database_name] < [backup_file.sql]

   - [username]: The MySQL username.
   - [database_name]: The name of the database you want to back up.
   - [backup_file.sql]:The name of the file where you want to save the backup.

Example:

mysql -u root -p mydatabase < mydatabase_backup.sql

After entering the command, you will be prompted to enter the password for the MySQL account.

Some additional commands and options:

- Back up all databases:

mysqldump -u [username] -p --all-databases > all_databases_backup.sql

- Backup with additional options, such as skipping specific tables:

mysqldump -u [username] -p [database_name] --ignore-table=[database_name].[table_name] > [backup_file.sql]

- Compress the backup file to save storage space:

mysqldump -u [username] -p [database_name] | gzip > [backup_file.sql.gz]

- Restore from a compressed file:

  gunzip < [backup_file.sql.gz] | mysql -u [username] -p [database_name]
