Management of MySQL users
=========================
:depends: - MySQLdb Python module
:configuration: See :py:mod:`salt.modules.mysql` for setup instructions.
.. code-block:: yaml
frank:
mysql_user.present:
- host: localhost
- password: bobcat
.. versionadded:: 0.16.2
Authentication overrides have been added.
The MySQL authentication information specified in the minion config file can be
overridden in states using the following arguments: ``connection_host``,
``connection_port``, ``connection_user``, ``connection_pass``,
``connection_db``, ``connection_unix_socket``, ``connection_default_file`` and
``connection_charset``.
.. code-block:: yaml
frank:
mysql_user.present:
- host: localhost
- password: "bob@cat"
- connection_user: someuser
- connection_pass: somepass
- connection_charset: utf8
- saltenv:
- LC_ALL: "en_US.utf8"
This state is not able to grant permissions for the user. See
:py:mod:`salt.states.mysql_grants` for further instructions.

Ensure that the named user is present with the specified properties. A
passwordless user can be configured by omitting ``password`` and

name
The name of the user to manage
host
Host for which this user/password combo applies
password
The password to use for this user. Will take precedence over the
``password_hash`` option if both are specified.
password_hash
The password in hashed form. Be sure to quote the password because YAML
doesn't like the ``*``. A password hash can be obtained from the mysql
command-line client like so::
mysql> SELECT PASSWORD('mypass');
+-------------------------------------------+
| PASSWORD('mypass') |

1 row in set (0.00 sec)
allow_passwordless
If ``True``, then ``password`` and ``password_hash`` can be omitted to
permit a passwordless login.
.. versionadded:: 0.16.2
unix_socket
If ``True`` and allow_passwordless is ``True``, the unix_socket auth
plugin will be used.
