This document describes how to migrate data through the console and command line tool.
There are two modes for migrating data through the console: physical backup and logical backup. For more information, see:
Note:
- The data files exported using mysqldump must be compatible with the SQL specification of your purchased TencentDB for MySQL version. You can log in to the database and get the MySQL version information by running the
select version();
command. The name of the generated SQL file can contain letters, digits, and underscores but not "test".- Make sure that the same source and target database versions, character sets, and mysqldump tool versions are used. You can specify the character set with the
--default-character-set
parameter.
shell > mysqldump [options] db_name [tbl_name ...] > bak_pathname
Here, options
is the export option, db_name
is the database name, tbl_name
is the table name, and bak_pathname
is the export path.shell > mysql -h hostname -P port -u username -p < bak_pathname
Here, hostname
is the target server for data restoration, port
is the port of target server, username
is the username of the database on the target server, and bak_pathname
is the full path to the backup file.show databases;
command, and you can see that the backup database has been imported into the target database.This document uses a Linux CVM instance as an example. For more information on how to access a database from a CVM instance, see Accessing MySQL Database.
