The mysqldump command in MySQL is used to create backups of MySQL databases. When dealing with sensitive data, securing data transmission over networks becomes crucial. The option --ssl-cipher=name allows configuring the SSL cipher used during the dump process, ensuring secure communication between the client and server.
Here are several examples demonstrating the usage of --ssl-cipher=name in mysqldump:
Example 1: Dump a database using a specific SSL cipher:
mysqldump --ssl-cipher=AES128-SHA database_name > backup.sql
This command dumps the database database_name using the SSL cipher AES128-SHA and saves the output to backup.sql.
Example 2: Dump all databases using a different SSL cipher:
mysqldump --ssl-cipher=DHE-RSA-AES256-SHA --all-databases > alldatabases_backup.sql
This command dumps all databases using the SSL cipher DHE-RSA-AES256-SHA and stores the dump in alldatabases_backup.sql.
Example 3: Dump a specific table with a custom SSL cipher:
mysqldump --ssl-cipher=ECDHE-RSA-AES128-GCM-SHA256 database_name table_name > table_backup.sql
Here, table_name from database_name is dumped using ECDHE-RSA-AES128-GCM-SHA256 cipher, saved in table_backup.sql.
Example 4: Use a different SSL cipher with compression:
mysqldump --ssl-cipher=AES256-SHA --compress database_name > backup.sql.gz
This command compresses the dump of database_name using SSL cipher AES256-SHA and saves it as backup.sql.gz.
Example 5: Dump a database with SSL cipher and specify username:
mysqldump --ssl-cipher=DHE-RSA-AES128-SHA --user=username database_name > backup.sql
This command dumps database_name using SSL cipher DHE-RSA-AES128-SHA with the specified username and saves it as backup.sql.
Example 6: Dump a database using a secure SSL cipher:
mysqldump --ssl-cipher=AES256-GCM-SHA384 database_name > backup.sql
This command securely dumps database_name using SSL cipher AES256-GCM-SHA384 and saves it as backup.sql.
Example 7: Dump a database with SSL cipher and include create database statements:
mysqldump --ssl-cipher=AES128-SHA --databases database_name > backup.sql
This command includes SSL cipher AES128-SHA when dumping database_name, along with create database statements saved in backup.sql.
Example 8: Dump all databases with SSL cipher and skip extended-inserts:
mysqldump --ssl-cipher=DHE-RSA-AES256-SHA --skip-extended-insert --all-databases > alldatabases_backup.sql
This command dumps all databases using SSL cipher DHE-RSA-AES256-SHA, skipping extended-inserts, stored in alldatabases_backup.sql.
Example 9: Dump a database with SSL cipher and specify a port:
mysqldump --ssl-cipher=AES256-SHA --port=3307 database_name > backup.sql
This command dumps database_name using SSL cipher AES256-SHA on port 3307, saving the result in backup.sql.
Example 10: Dump a database using a custom SSL cipher and specify socket:
mysqldump --ssl-cipher=ECDHE-RSA-AES256-SHA384 --socket=/path/to/mysql.sock database_name > backup.sql
This command dumps database_name using SSL cipher ECDHE-RSA-AES256-SHA384 via a specific socket path, storing the result in backup.sql.
To verify that the mysqldump command executed successfully, you can check the content of the generated backup files (backup.sql, alldatabases_backup.sql, etc.) using a text editor or by importing them back into a MySQL server to ensure data integrity and correctness.
