Requirements

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

  • PyMySQL (Python 2.7 and Python 3.X), or
  • MySQLdb (Python 2.x)

Parameters

Parameter Choices/Defaults Comments
append_privs
boolean
    Choices:
  • no ←
  • yes
Append the privileges defined by priv to the existing ones for this user instead of overwriting existing ones.
ca_cert
path
added in 2.0
The path to a Certificate Authority (CA) certificate. This option, if used, must specify the same certificate as used by the server.

aliases: ssl_ca
check_implicit_admin
boolean
    Choices:
  • no ←
  • yes
Check if mysql allows login as root/nopassword before trying supplied credentials.
client_cert
path
added in 2.0
The path to a client public key certificate.

aliases: ssl_cert
client_key
path
added in 2.0
The path to the client private key.

aliases: ssl_key
config_file
path
added in 2.0
Default:
"~/.my.cnf"
Specify a config file from which user and password are to be read.
connect_timeout
integer
added in 2.1
Default:
30
The connection timeout when connecting to the MySQL server.
encrypted
boolean
added in 2.0
    Choices:
  • no ←
  • yes
Indicate that the 'password' field is a `mysql_native_password` hash.
host
string
Default:
"localhost"
The 'host' part of the MySQL username.
host_all
boolean
added in 2.1
    Choices:
  • no ←
  • yes
Override the host option, making ansible apply changes to all hostnames for a given user.
This option cannot be used when creating users.
login_host
string
Default:
"localhost"
Host running the database.
login_password
string
The password used to authenticate with.
login_port
integer
Default:
3306
Port of the MySQL server. Requires login_host be defined as other than localhost if login_port is used.
login_unix_socket
string
The path to a Unix domain socket for local connections.
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..
priv
string
MySQL privileges string in the format: db.table:priv1,priv2.
Multiple privileges can be specified by separating each one using a forward slash: db.table:priv/db.table: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))).
sql_log_bin
boolean
added in 2.1
    Choices:
  • no
  • yes ←
Whether binary logging should be enabled or disabled for the connection.
state
string
    Choices:
  • absent
  • present ←
Whether the user should exist.
When absent, removes the user.
update_password
string
added in 2.0
    Choices:
  • always ←
  • on_create
always will update passwords if they differ.
on_create will only set the password for newly created users.

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: the first must change the root user’s password, without providing any login_user/login_password details. The second must 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.
  • Requires the PyMySQL (Python 2.7 and Python 3.X) or MySQL-python (Python 2.X) package on the remote host. The Python package may be installed with apt-get install python-pymysql (Ubuntu; see apt) or yum install python2-PyMySQL (RHEL/CentOS/Fedora; see yum). You can also use dnf install python2-PyMySQL for newer versions of Fedora; see dnf.
  • 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.
