community.mysql.mysql_user module – Adds or removes a user from a MySQL database

Note

This module is part of the community.mysql collection (version 3.5.1).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.mysql.

To use it in a playbook, specify: community.mysql.mysql_user.

Synopsis

  • Adds or removes a user from a MySQL database.

Requirements

The below requirements are needed on the host that executes this module.

  • mysqlclient (Python 3.5+) or

  • PyMySQL (Python 2.7 and Python 3.x) or

  • MySQLdb (Python 2.x)

Parameters

Parameter

Comments

append_privs

boolean

Append the privileges defined by priv to the existing ones for this user instead of overwriting existing ones. Mutually exclusive with subtract_privs.

Choices:

  • no ← (default)

  • yes

ca_cert

aliases: ssl_ca

path

The path to a Certificate Authority (CA) certificate. This option, if used, must specify the same certificate as used by the server.

check_hostname

boolean

added in 1.1.0 of community.mysql

Whether to validate the server host name when an SSL connection is required. Corresponds to MySQL CLIs --ssl switch.

Setting this to false disables hostname verification. Use with caution.

Requires pymysql >= 0.7.11.

This option has no effect on MySQLdb.

Choices:

  • no

  • yes

check_implicit_admin

boolean

Check if mysql allows login as root/nopassword before trying supplied credentials.

If success, passed login_user/login_password will be ignored.

Choices:

  • no ← (default)

  • yes

client_cert

aliases: ssl_cert

path

The path to a client public key certificate.

client_key

aliases: ssl_key

path

The path to the client private key.

config_file

path

Specify a config file from which user and password are to be read.

The default config file, ~/.my.cnf, if it exists, will be read, even if config_file is not specified.

The default config file, ~/.my.cnf, if it exists, must contain a [client] section as a MySQL connector requirement.

To prevent the default config file from being read, set config_file to be an empty string.

Default: “~/.my.cnf”

connect_timeout

integer

The connection timeout when connecting to the MySQL server.

Default: 30

encrypted

boolean

Indicate that the ‘password’ field is a mysql_native_password hash.

Choices:

  • no ← (default)

  • yes

force_context

boolean

added in 3.1.0 of community.mysql

Sets the С(mysql) system database as context for the executed statements (it will be used as a database to connect to). Useful if you use binlog / replication filters in MySQL as per default the statements can not be caught by a binlog / replication filter, they require a database to be set to work, otherwise the replication can break down.

See https://dev.mysql.com/doc/refman/8.0/en/replication-options-binary-log.html#option_mysqld_binlog-ignore-db for a description on how binlog filters work (filtering on the primary).

See https://dev.mysql.com/doc/refman/8.0/en/replication-options-replica.html#option_mysqld_replicate-ignore-db for a description on how replication filters work (filtering on the replica).

Choices:

  • no ← (default)

  • yes

host

string

The ‘host’ part of the MySQL username.

Default: “localhost”

host_all

boolean

Override the host option, making ansible apply changes to all hostnames for a given user.

This option cannot be used when creating users.

Choices:

  • no ← (default)

  • yes

login_host

string

Host running the database.

In some cases for local connections the login_unix_socket=/path/to/mysqld/socket, that is usually /var/run/mysqld/mysqld.sock, needs to be used instead of login_host=localhost.

Default: “localhost”

login_password

string

The password used to authenticate with.

login_port

integer

Port of the MySQL server. Requires login_host be defined as other than localhost if login_port is used.

Default: 3306

login_unix_socket

string

The path to a Unix domain socket for local connections.

Use this parameter to avoid the Please explicitly state intended protocol error.

login_user

string

The username used to authenticate with.

name

string / required

Name of the user (role) to add or remove.

password

string

Set the user’s password. Only for mysql_native_password authentication. For other authentication plugins see the combination of plugin, plugin_hash_string, plugin_auth_string.

plugin

string

added in 0.1.0 of community.mysql

User’s plugin to authenticate (CREATE USER user IDENTIFIED WITH plugin).

plugin_auth_string

string

added in 0.1.0 of community.mysql

User’s plugin auth_string (CREATE USER user IDENTIFIED WITH plugin BY plugin_auth_string).

plugin_hash_string

string

added in 0.1.0 of community.mysql

User’s plugin hash string (CREATE USER user IDENTIFIED WITH plugin AS plugin_hash_string).

priv

raw

MySQL privileges string in the format: db.table:priv1,priv2.

Multiple privileges can be specified by separating each one using a forward slash: db.table1:priv/db.table2:priv.

The format is based on MySQL GRANT statement.

Database and table names can be quoted, MySQL-style.

If column privileges are used, the priv1,priv2 part must be exactly as returned by a SHOW GRANT statement. If not followed, the module will always report changes. It includes grouping columns by permission (SELECT(col1,col2) instead of SELECT(col1,SELECT(col2))).

Can be passed as a dictionary (see the examples).

Supports GRANTs for procedures and functions (see the examples).

Note: If you pass the same db.table combination to this parameter two or more times with different privileges, for example, '*.*:SELECT/*.*:SHOW VIEW', only the last one will be applied, in this example, it will be SHOW VIEW respectively. Use '*.*:SELECT,SHOW VIEW' instead to apply both.

resource_limits

dictionary

added in 0.1.0 of community.mysql

Limit the user for certain server resources. Provided since MySQL 5.6 / MariaDB 10.2.

Available options are MAX_QUERIES_PER_HOUR: num, MAX_UPDATES_PER_HOUR: num, MAX_CONNECTIONS_PER_HOUR: num, MAX_USER_CONNECTIONS: num.

Used when state=present, ignored otherwise.

sql_log_bin

boolean

Whether binary logging should be enabled or disabled for the connection.

Choices:

  • no

  • yes ← (default)

state

string

Whether the user should exist.

When absent, removes the user.

Choices:

  • absent

  • present ← (default)

subtract_privs

boolean

added in 3.2.0 of community.mysql

Revoke the privileges defined by the priv option and keep other existing privileges. If set, invalid privileges in priv are ignored. Mutually exclusive with append_privs.

Choices:

  • no ← (default)

  • yes

tls_requires

dictionary

added in 1.0.0 of community.mysql

Set requirement for secure transport as a dictionary of requirements (see the examples).

Valid requirements are SSL, X509, SUBJECT, ISSUER, CIPHER.

SUBJECT, ISSUER and CIPHER are complementary, and mutually exclusive with SSL and X509.

https://mariadb.com/kb/en/securing-connections-for-client-and-server/#requiring-tls.

update_password

string

always will update passwords if they differ. This affects password and the combination of plugin, plugin_hash_string, plugin_auth_string.

on_create will only set the password or the combination of plugin, plugin_hash_string, plugin_auth_string for newly created users.

on_new_username works like on_create, but it tries to reuse an existing password: If one different user with the same username exists, or multiple different users with the same username and equal plugin and authentication_string attribute, the existing plugin and authentication_string are used for the new user instead of the password, plugin, plugin_hash_string or plugin_auth_string argument.

Choices:

  • always ← (default)

  • on_create

  • on_new_username

Notes

Note

  • MySQL server installs with default login_user of root and no password. To secure this user as part of an idempotent playbook, you must create at least two tasks: 1) change the root user’s password, without providing any login_user/login_password details, 2) drop a ~/.my.cnf file containing the new root credentials. Subsequent runs of the playbook will then succeed by reading the new credentials from the file.

  • Currently, there is only support for the mysql_native_password encrypted password hash module.

  • Supports (check_mode).

  • To avoid the Please explicitly state intended protocol error, use the login_unix_socket argument, for example, login_unix_socket: /run/mysqld/mysqld.sock.

  • Requires the PyMySQL (Python 2.7 and Python 3.X) or MySQL-python (Python 2.X) package installed on the remote host. The Python package may be installed with apt-get install python-pymysql (Ubuntu; see ansible.builtin.apt) or yum install python2-PyMySQL (RHEL/CentOS/Fedora; see ansible.builtin.yum). You can also use dnf install python2-PyMySQL for newer versions of Fedora; see ansible.builtin.dnf.

  • Be sure you have mysqlclient, PyMySQL, or MySQLdb library installed on the target machine for the Python interpreter Ansible discovers. For example if ansible discovers and uses Python 3, you need to install the Python 3 version of PyMySQL or mysqlclient. If ansible discovers and uses Python 2, you need to install the Python 2 version of either PyMySQL or MySQL-python.

  • If you have trouble, it may help to force Ansible to use the Python interpreter you need by specifying ansible_python_interpreter. For more information, see https://docs.ansible.com/ansible/latest/reference_appendices/interpreter_discovery.html.

  • Both login_password and login_user are required when you are passing credentials. If none are present, the module will attempt to read the credentials from ~/.my.cnf, and finally fall back to using the MySQL default login of ‘root’ with no password.

  • If there are problems with local connections, using login_unix_socket=/path/to/mysqld/socket instead of login_host=localhost might help. As an example, the default MariaDB installation of version 10.4 and later uses the unix_socket authentication plugin by default that without using login_unix_socket=/var/run/mysqld/mysqld.sock (the default path) causes the error Host '127.0.0.1' is not allowed to connect to this MariaDB server.

  • Alternatively, you can use the mysqlclient library instead of MySQL-python (MySQLdb) which supports both Python 2.X and Python >=3.5. See https://pypi.org/project/mysqlclient/ how to install it.

  • If credentials from the config file (for example, /root/.my.cnf) are not needed to connect to a database server, but the file exists and does not contain a [client] section, before any other valid directives, it will be read and this will cause the connection to fail, to prevent this set it to an empty string, (for example config_file: '').
