Configuring SSL Connection Mode in mysqldump can enhance security when dumping MySQL databases. The option --ssl-mode=name
specifies how mysqldump should handle SSL (Secure Socket Layer) connections during the dump process.
Here are several examples demonstrating the usage of --ssl-mode=name
in mysqldump:
Example 1: Using SSL for the connection.
mysqldump --ssl-mode=REQUIRED -u username -p database_name > database_dump.sql
This command dumps the database_name
database into database_dump.sql
file using SSL with required mode. To verify, check if database_dump.sql
file exists and contains SQL dump data.
Example 2: Using SSL but allowing insecure connections if SSL setup fails.
mysqldump --ssl-mode=PREFERRED -u username -p database_name > database_dump.sql
Here, mysqldump attempts an SSL connection (preferred mode), falling back to an unencrypted connection if SSL setup fails. Verify the dump file similarly as in Example 1.
Example 3: Not using SSL at all for the connection.
mysqldump --ssl-mode=DISABLED -u username -p database_name > database_dump.sql
This command disables SSL for the dump operation. Verify the absence of SSL-related errors in the output and dump file.
Example 4: Using SSL only if the server supports it.
mysqldump --ssl-mode=VERIFY_CA -u username -p database_name > database_dump.sql
This verifies the server’s certificate but does not require it to be signed by a trusted CA. Verify by checking the presence of SSL verification messages in the output.
Example 5: Using SSL, verifying the server’s certificate against a trusted CA.
mysqldump --ssl-mode=VERIFY_IDENTITY -u username -p database_name > database_dump.sql
Here, SSL connection is established and the server’s certificate is verified against a trusted CA. Check for SSL identity verification messages in the output.
Each of these examples demonstrates different levels of SSL configuration in mysqldump, catering to various security needs and server capabilities. By examining the output and dump file, you can ensure the SSL mode specified is correctly applied during the database dump process.
