## Synopsis

- Gathers information about MySQL servers.

## 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
--- | --- | ---
ca_cert path |  | 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
client_cert path |  | The path to a client public key certificate. aliases: ssl_cert
client_key path |  | The path to the client private key. aliases: ssl_key
config_file path | Default: "~/.my.cnf" | Specify a config file from which user and password are to be read.
connect_timeout integer | Default: 30 | The connection timeout when connecting to the MySQL server.
filter list / elements=string |  | Limit the collected information by comma separated string or YAML list. Allowable values are `version`, `databases`, `settings`, `users`, `slave_status`, `slave_hosts`, `master_status`, `engines`. By default, collects all subsets. You can use '!' before value (for example, `!settings`) to exclude it from the information. If you pass including and excluding values to the filter, for example, filter=!settings,version, the excluding values, `!settings` in this case, will be ignored.
login_db string |  | Database name to connect to. It makes sense if login_user is allowed to connect to a specific database only.
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.

## Notes

Note

- 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.

## Examples

    # Display info from mysql-hosts group (using creds from ~/.my.cnf to connect):
    # ansible mysql-hosts -m mysql_info

    # Display only databases and users info:
    # ansible mysql-hosts -m mysql_info -a 'filter=databases,users'

    # Display only slave status:
    # ansible standby -m mysql_info -a 'filter=slave_status'

    # Display all info from databases group except settings:
    # ansible databases -m mysql_info -a 'filter=!settings'

    - name: Collect all possible information using passwordless root access
      mysql_info:
        login_user: root

    - name: Get MySQL version with non-default credentials
      mysql_info:
        login_user: mysuperuser
        login_password: mysuperpass
        filter: version

    - name: Collect all info except settings and users by root
      mysql_info:
        login_user: root
        login_password: rootpass
        filter: "!settings,!users"

    - name: Collect info about databases and version using ~/.my.cnf as a credential file
      become: yes
      mysql_info:
        filter:
        - databases
        - version

    - name: Collect info about databases and version using ~alice/.my.cnf as a credential file
      become: yes
      mysql_info:
        config_file: /home/alice/.my.cnf
        filter:
        - databases

## Return Values
