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
Display output in grid or table format like that of the mysql monitor.

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 destination server must have

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