Migrating Data to RDS for MySQL Using mysqldump

• To connect to a DB instance through an ECS, you need to create an ECS first.
• To connect to a DB instance through an EIP, you must:
  1. Bind an EIP to the DB instance. For details, see Binding an EIP.
  2. Ensure that the local device can access the EIP.

For details, see How Can I Install the MySQL Client?

The MySQL client version must be the same as the DB engine version of your RDS for MySQL instance. A MySQL database or client will provide mysqldump and mysql.

After data is migrated to RDS, you may need to change the IP address. For details, see Viewing and Changing a Floating IP Address.

RDS system databases mysql and sys cannot be imported from one RDS for MySQL instance to another.

The mysql database is required for RDS management. When exporting the table structure, do not specify --all-database. Otherwise, a database fault will occur.

mysqldump--databases<DB_NAME>--single-transaction --order-by-primary --hex-blob --no-data --routines --events --set-gtid-purged=OFF-u <DB_USER>-p -h<DB_ADDRESS>-P <DB_PORT>|sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' -e 's/DEFINER[ ]*=.*FUNCTION/FUNCTION/' -e 's/DEFINER[ ]*=.*PROCEDURE/PROCEDURE/' -e 's/DEFINER[ ]*=.*TRIGGER/TRIGGER/' -e 's/DEFINER[ ]*=.*EVENT/EVENT/' ><BACKUP_FILE>

• DB_NAME indicates the name of the database to be migrated.
• DB_USER indicates the database username.
• DB_ADDRESS indicates the database address.
• DB_PORT indicates the database port.
• BACKUP_FILE indicates the name of the file to which the data will be exported.

Enter the database password when prompted.

Example:

mysqldump --databases rdsdb --single-transaction --order-by-primary --hex-blob --no-data --routines --events --set-gtid-purged=OFF -u root -p -h 192.168.151.18 -P 3306 |sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' -e 's/DEFINER[ ]*=.*FUNCTION/FUNCTION/' -e 's/DEFINER[ ]*=.*PROCEDURE/PROCEDURE/' -e 's/DEFINER[ ]*=.*TRIGGER/TRIGGER/' -e 's/DEFINER[ ]*=.*EVENT/EVENT/' > dump-defs.sql

Enter password:

If you use mysqldump with a version earlier than 5.6, remove --set-gtid-purged=OFF before running this command.

After this command is executed, a dump-defs.sql file will be generated as follows:

[rds@localhost ~]$ ll dump-defs.sql
-rw-r-----. 1 rds rds 2714 Sep 21 08:23 dump-defs.sql

The mysql database is required for RDS management. When exporting data, do not specify --all-database. Otherwise, a database fault will occur.

mysqldump --databases<DB_NAME>--single-transaction --hex-blob --set-gtid-purged=OFF --no-create-info --skip-triggers-u<DB_USER>-p-h<DB_ADDRESS>-P<DB_PORT>-r<BACKUP_FILE>

For details on the parameters in the preceding command, see 2.

Enter the database password when prompted.

Example:

mysqldump --databases rdsdb --single-transaction --hex-blob --set-gtid-purged=OFF --no-create-info --skip-triggers -u root -p -h 192.168.151.18 -P 3306 -r dump-data.sql

If you use mysqldump with a version earlier than 5.6, remove --set-gtid-purged=OFF before running this command.

After this command is executed, a dump-data.sql file will be generated as follows:

[rds@localhost ~]$ ll dump-data.sql
-rw-r-----. 1 rds rds 2714 Sep 21 08:23 dump-data.sql

# mysql -f -h<RDS_ADDRESS>-P<DB_PORT>-uroot-p < <BACKUP_DIR>/dump-defs.sql

• RDS_ADDRESS indicates the IP address of the RDS DB instance.
• DB_PORT indicates the RDS DB instance port.
• BACKUP_DIR indicates the directory where dump-defs.sql is stored.

Example:

# mysql -f -h 172.16.66.198 -P 3306 -u root -p < dump-defs.sql

Enter password:

If you intend to import SQL statements of a table to RDS, specify a database in the command. Otherwise, the error message "No database selected" may be displayed. For example, if you intend to import SQL statements of a table to database mydb, run the following command:

# mysql -f -h 172.16.66.198 -P 3306 -u root -p mydb < dump-defs.sql

Enter password:

# mysql -f -h<RDS_ADDRESS>-P<DB_PORT>-uroot-p< <BACKUP_DIR>/dump-data.sql

• RDS_ADDRESS indicates the IP address of the RDS DB instance.
• DB_PORT indicates the RDS DB instance port.
• BACKUP_DIR indicates the directory where dump-data.sql is stored.

Example:

# mysql -f -h 172.16.66.198 -P 3306 -u root -p < dump-data.sql
