5.21.1 mysqluserclone — Clone Existing User to Create New User

This utility uses an existing MySQL user account on one server as a template, and clones it to create one or more new user accounts with the same privileges as the original user. The new users can be created on the original server or a different server.

To list users for a server, specify the --list option. This prints a list of the users on the source (no destination is needed). To control how to display list output, use one of the following values with the --format option:

OPTIONS

mysqluserclone accepts the following command-line options:

NOTES

You must provide connection parameters (user, host, password, and so forth) for an account that has the appropriate privileges to access all objects in the operation.

The account used to connect to the source server must have privileges to read the mysql database.

The account used to connect to the destination server must have privileges to execute CREATE USER (and DROP USER if the --force option is given), and privileges to execute GRANT for all privileges to be granted to the new accounts.

For the --format option, the permitted values are not case sensitive. In addition, values may be specified as any unambiguous prefix of a valid value. For example, --format=g specifies the grid format. An error occurs if a prefix matches more than one valid value.

The path to the MySQL client tools should be included in the PATH environment variable in order to use the authentication mechanism with login-paths. This will allow the utility to use the my_print_defaults tools which is required to read the login-path values from the login configuration file (.mylogin.cnf).

EXAMPLES

To clone joe as sam and sally with passwords and logging in as root on the local machine, use this command:

$ mysqluserclone --source=root@localhost \
  --destination=root@localhost \
  joe@localhost sam:secret1@localhost sally:secret2@localhost
# Source on localhost: ... connected.
# Destination on localhost: ... connected.
# Cloning 2 users...
# Cloning joe@localhost to user sam:secret1@localhost
# Cloning joe@localhost to user sally:secret2@localhost
# ...done.

The following command shows all users on the local server in the most verbose output in CSV format:

$ mysqluserclone --source=root@localhost --list --format=csv -vvv
# Source on localhost: ... connected.
user,host,database
joe,localhost,util_test
rpl,localhost,
sally,localhost,util_test
sam,localhost,util_test
joe,user,util_test

PERMISSIONS REQUIRED

The permissions required include the ability to read the mysql database and to have read access to the data directory.
