The mysqldump command in MySQL is used to create backups of databases. When dealing with SSL connections, particularly when specifying the CA (Certificate Authority) directory path, the --ssl-capath=name option becomes crucial. This option allows you to specify the directory where MySQL client programs such as mysqldump can find trusted SSL CA certificates.
Here are several examples of how to use --ssl-capath=name with mysqldump:
Example 1: Dump a database using SSL with a specific CA directory:
mysqldump --ssl-capath=/etc/mysql/ssl/certs -u username -p database_name > backup.sql
This command exports the database database_name using SSL certificates located in /etc/mysql/ssl/certs.
Example 2: Dump all databases with SSL using a different CA directory:
mysqldump --ssl-capath=/home/user/sslcerts -u username -p --all-databases > all_databases.sql
This command dumps all databases on the server using SSL certificates from /home/user/sslcerts.
Example 3: Dump a specific table using SSL with a CA directory path:
mysqldump --ssl-capath=/etc/ssl/mysql -u username -p database_name table_name > table_backup.sql
Here, table_name from database_name is dumped using SSL certificates from /etc/ssl/mysql.
Example 4: Dump a database over SSL with a custom CA directory for certificates:
mysqldump --ssl-capath=/usr/local/ssl/certs -u username -p --databases db1 db2 > dbs_backup.sql
This command backs up databases db1 and db2 using SSL certificates found in /usr/local/ssl/certs.
Example 5: Dump a database with SSL, specifying a CA directory path with multiple certificates:
mysqldump --ssl-capath=/etc/ssl/certs -u username -p database_name > db_backup.sql
This command exports database_name using SSL certificates from /etc/ssl/certs.
Example 6: Dump a database with SSL using a centralized CA directory:
mysqldump --ssl-capath=/opt/mysql-ssl/certs -u username -p database_name > backup.sql
Here, SSL certificates from /opt/mysql-ssl/certs are used to back up database_name.
Example 7: Dump all databases over SSL with a specified CA directory:
mysqldump --ssl-capath=/usr/local/mysql-ssl/certs -u username -p --all-databases > all_databases.sql
This command dumps all databases using SSL certificates from /usr/local/mysql-ssl/certs.
Example 8: Dump a specific table using SSL with a particular CA directory:
mysqldump --ssl-capath=/etc/mysql/ssl -u username -p database_name table_name > table_backup.sql
This command backs up table_name from database_name using SSL certificates from /etc/mysql/ssl.
Example 9: Dump a database over SSL with a custom CA directory path:
mysqldump --ssl-capath=/home/user/mysql-ssl/certs -u username -p --databases db1 db2 > dbs_backup.sql
This command exports databases db1 and db2 using SSL certificates from /home/user/mysql-ssl/certs.
Example 10: Dump a database with SSL, specifying a unique CA directory path:
mysqldump --ssl-capath=/var/lib/mysql/ssl -u username -p database_name > db_backup.sql
This command creates a backup of database_name using SSL certificates from /var/lib/mysql/ssl.
To verify if the mysqldump command executed successfully with SSL and the specified CA directory, check the generated backup files. Ensure the files are created without errors and review their contents to confirm the databases or tables were dumped correctly with SSL encryption using the specified CA certificates.
