MySQL is a widely-used open-source relational database management system. Importing and exporting MySQL databases are common tasks when managing or migrating data between servers or applications.
In this guide, we will demonstrate how to import and export MySQL databases using the command line in Linux.
Step 1: Export MySQL Database
To export a MySQL database, use the mysqldump utility. Replace username, password, and database_name with the appropriate values for your MySQL server and database:
mysqldump -u username -p password database_name > database_name.sql
The command above will create a new file called database_name.sql containing the SQL statements needed to recreate the database.
If you want to export a specific table from the database, you can add the table name after the database name:
mysqldump -u username -p password database_name table_name > table_name.sql
Step 2: Import MySQL Database
To import a MySQL database, use the mysql command. Replace username, password, database_name, and file.sql with the appropriate values for your MySQL server, database, and SQL file:
mysql -u username -p password database_name < file.sql
The command above will import the SQL statements from file.sql into the specified database.
If you need to import a specific table into an existing database, make sure the SQL file contains only the statements related to that table, and then execute the command above.
