How to back up the entire MySQL database?

mysqldump -u 用户名 -p 密码 数据库名 > 备份文件路径

For example, backup the database named “testdb” to the file “backup.sql”.

mysqldump -u root -p testdb > /path/to/backup.sql

This command will back up the structure and data of the entire database to the specified file.

1. Back up the database using MySQL Workbench.
