Synopsis

Requirements

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

  • PyMySQL

  • mysqlclient

Parameters

Parameter

Comments

active

boolean

A user with active set to False will be tracked in the database, but will be never loaded in the in-memory data structures. If omitted the proxysql database default for active is True.

Choices:

  • no

  • yes

backend

boolean

If backend is set to True, this (username, password) pair is used for authenticating to the ProxySQL instance.

Choices:

  • no

  • yes ← (default)

config_file

path

Specify a config file from which login_user and login_password are to be read.

Default: “”

default_hostgroup

integer

If there is no matching rule for the queries sent by this user, the traffic it generates is sent to the specified hostgroup. If omitted the proxysql database default for use_ssl is 0.

default_schema

string

The schema to which the connection should change to by default.

encrypt_password

boolean

Encrypt a cleartext password passed in the password option, using the method defined in encryption_method.

  • yes

encryption_method

string

Encryption method used when encrypt_password is set to True.

Choices:

  • mysql_native_password ← (default)

fast_forward

boolean

If fast_forward is set to True, fast_forward will bypass the query processing layer (rewriting, caching) and pass through the query directly as is to the backend server. If omitted the proxysql database default for fast_forward is False.

Choices:

  • no

  • yes

frontend

boolean

If frontend is set to True, this (username, password) pair is used for authenticating to the mysqld servers against any hostgroup.

Choices:

  • no

  • yes ← (default)

login_user

string

Choices:

  • no

  • yes

use_ssl

Examples

---
# This example adds a user, it saves the mysql user config to disk, but
# avoids loading the mysql user config to runtime (this might be because
# several users are being added and the user wants to push the config to
# runtime in a single batch using the community.general.proxysql_manage_config
# module).  It uses supplied credentials to connect to the proxysql admin
# interface.

- name: Add a user
  community.proxysql.proxysql_mysql_users:
    login_user: 'admin'
    login_password: 'admin'
    username: 'productiondba'
    state: present
    load_to_runtime: False

# This example removes a user, saves the mysql user config to disk, and
# dynamically loads the mysql user config to runtime.  It uses credentials
# in a supplied config file to connect to the proxysql admin interface.

- name: Remove a user
  community.proxysql.proxysql_mysql_users:
    config_file: '~/proxysql.cnf'
    username: 'mysqlboy'
    state: absent
