Setting Certificate Revocation List Path in mysqldump

The mysqldump command in MySQL is used to create backups of databases. When dealing with secure connections, you might need to specify a Certificate Revocation List (CRL) path using the --ssl-crlpath=name option. This option allows you to provide the path to a file containing a list of revoked certificates that MySQL should consider invalid. Here are several examples demonstrating the usage of --ssl-crlpath=name in mysqldump:

Example 1: Dumping a database with SSL CRL path specified
mysqldump --ssl-crlpath=/path/to/crl.pem -u username -p database_name > backup.sql

This command creates a backup of database_name while specifying the SSL CRL path as /path/to/crl.pem. The output is redirected to backup.sql.

Example 2: Dumping all databases with SSL CRL path
mysqldump --ssl-crlpath=/path/to/crl.pem -u username -p --all-databases > alldatabases_backup.sql

Here, all databases are dumped, and the SSL CRL path is set to /path/to/crl.pem. The resulting dump is saved in alldatabases_backup.sql.

Example 3: Dumping a specific table with SSL CRL path
mysqldump --ssl-crlpath=/path/to/crl.pem -u username -p database_name table_name > table_backup.sql

This command backs up only table_name from database_name, utilizing the SSL CRL path specified.

Example 4: Dumping with SSL CRL path and compression
mysqldump --ssl-crlpath=/path/to/crl.pem -u username -p --compress database_name > backup.sql.gz

Here, database_name is dumped with SSL CRL path set and compressed into backup.sql.gz.

Example 5: Dumping with SSL CRL path and excluding a table
mysqldump --ssl-crlpath=/path/to/crl.pem -u username -p --ignore-table=database_name.table_name database_name > backup.sql

This command excludes table_name from the dump of database_name, using the specified SSL CRL path.

Example 6: Dumping with SSL CRL path and specifying character set
mysqldump --ssl-crlpath=/path/to/crl.pem -u username -p --default-character-set=utf8 database_name > backup.sql

This command dumps database_name with SSL CRL path and sets the character set to UTF-8.

Example 7: Dumping with SSL CRL path and specifying extended-insert
mysqldump --ssl-crlpath=/path/to/crl.pem -u username -p --extended-insert=FALSE database_name > backup.sql

This command dumps database_name while disabling extended inserts and using the SSL CRL path.

Example 8: Dumping with SSL CRL path and using tab-delimited output
mysqldump --ssl-crlpath=/path/to/crl.pem -u username -p --tab=/path/to/dump_folder database_name

This command creates tab-delimited output for database_name in the specified folder, using the SSL CRL path.

Example 9: Dumping with SSL CRL path and ignoring SQL errors
mysqldump --ssl-crlpath=/path/to/crl.pem -u username -p --force database_name > backup.sql

This command forces mysqldump to continue even if it encounters SQL errors, with SSL CRL path specified.

Example 10: Dumping with SSL CRL path and locking tables
mysqldump --ssl-crlpath=/path/to/crl.pem -u username -p --lock-tables database_name > backup.sql

This command locks tables in database_name during the dump process, using the specified SSL CRL path.

Verification: To verify whether the mysqldump command executed successfully with the SSL CRL path, check the generated output file (e.g., backup.sql). If the file exists and contains data from the specified database(s), the command executed as intended.
