Setting Certificate Revocation List in mysqldump

The mysqldump command in MySQL is used to create backups of MySQL databases. One of the options available is --ssl-crl=name, which allows you to specify a Certificate Revocation List (CRL) file for use in SSL connections during the dump process.

Here are some examples demonstrating the usage of --ssl-crl=name:

Example 1: Dump a MySQL database with SSL and specify a CRL file.

mysqldump --ssl --ssl-crl=/path/to/crl_file dbname > dbname_backup.sql

This command connects to the MySQL server using SSL, verifies the server’s certificate against the CRL specified in /path/to/crl_file, and dumps the database dbname into dbname_backup.sql.

Example 2: Dump all databases from a MySQL server with SSL and CRL verification.

mysqldump --ssl --ssl-crl=/etc/mysql/crl.pem --all-databases > alldatabases_backup.sql

Here, all databases from the MySQL server are dumped into alldatabases_backup.sql. The CRL file located at /etc/mysql/crl.pem is used to verify SSL certificates.

Example 3: Dump a specific table with SSL and CRL verification.

mysqldump --ssl --ssl-crl=/usr/local/mysql/crl.pem dbname tablename > dbname_tablename_backup.sql

This command dumps only the tablename from database dbname into dbname_tablename_backup.sql, using the CRL file located at /usr/local/mysql/crl.pem for SSL certificate verification.

To verify if the mysqldump command executed successfully, check the content and size of the generated backup file. Additionally, you can inspect any error messages that might indicate issues with SSL or CRL verification.
