How to Run MySQL Database Backup Command Line

The command-line tool mysqldump is used to create a logical backup of a MySQL database. Furthermore, it can generate output in CSV, delimited text, or XML format.

However, you should note that the SQL commands required to re-create or restore the database are generated within the backup file when you create a backup of the MySQL database. Therefore, if your database is large, this process can be time-consuming. Keep reading to learn how to generate a backup of your MySQL database.

Create a Backup of a Single Database

To back up a single MySQL database, you can enter the following commands (replace 'username' with your actual username):

Translate the following text into English: `
• mysqldump -u database_username -p database_name > database_backup_file.sql
` This command translates to: `mysqldump -u [database_username] -p [database_name] > [database_backup_file.sql]` In plain English: This is a command to create a backup of a MySQL database. Replace `[database_username]` with your actual database username, `[database_name]` with the name of the database you want to back up, and `[database_backup_file.sql]` with the desired filename for the backup file (in SQL format). The `-p` flag will prompt for the password for the specified user.

接下来，它会提示输入密码。如果你忘记了密码，可以输入以下命令来跳过密码：

Translate the following text into English, focusing on translation only: `
• mysqldump -u database_username --password="database_password" database_name > database_backup_file.sql
` This command translates to: `mysqldump -u [database_username] --password="[database_password]" [database_name] > [database_backup_file.sql]` In English, this is a command to create a backup of a MySQL database. Replace the placeholders with actual values: - `[database_username]`: The username for the database. - `[database_password]`: The password for the database. - `[database_name]`: The name of the database you want to back up. - `[database_backup_file.sql]`: The file where the backup will be stored in SQL format.

Translate the following text into English, focusing on translation only: `
• mysqldump -u database_username -p --databases database_name1 database_name2 > database_backup_file.sql
`

Next, enter the following line to bypass the password prompt:

Translate the following text into English: `
• mysqldump -u database_username --password="database_password" --databases database_name1 database_name2 > database_backup_file.sql
` This command is used to create a backup of MySQL databases. Here's the translation: `
• mysqldump -u [database_username] --password="[database_password]" --databases [database_name1] [database_name2] > [database_backup_file.sql]
` In English, this would be: `
• mysqldump -u [username_for_database] --password=[your_database_password] --databases [name_of_database1] [name_of_database2] > [backup_file_name.sql]
` Please replace the placeholders in square brackets with actual values specific to your setup.

When restoring MySQL, you need to use the `mysql` tool instead of `mysqldump`.

Step 1. Delete the original database and create a new one by executing the following commands:

• mysql> drop database username;
• Query OK, 24 rows affected (0.35 sec)
• mysql> create database username1;
• Query OK, 1 row affected (0.01 sec)
• MySQL>
