# MySQL/MariaDB Database Plugin HTTP API
|
||
|
||
The MySQL database plugin is one of the supported plugins for the database
|
||
secrets engine. This plugin generates database credentials dynamically based on
|
||
configured roles for the MySQL database.
|
||
|
||
## Configure Connection
|
||
|
||
In addition to the parameters defined by the [Database
|
||
Backend](/api/secret/databases/index.html#configure-connection), this plugin
|
||
has a number of parameters to further configure a connection.
|
||
|
||
| Method | Path | Produces |
|
||
| :------- | :--------------------------- | :--------------------- |
|
||
| `POST` | `/database/config/:name` | `204 (empty body)` |
|
||
|
||
### Parameters
|
||
- `connection_url` `(string: <required>)` - Specifies the MySQL DSN. This field
|
||
can be templated and supports passing the username and password
|
||
parameters in the following format {{field_name}}. A templated connection URL is
|
||
required when using root credential rotation.
|
||
|
||
- `max_open_connections` `(int: 2)` - Specifies the maximum number of open
|
||
connections to the database.
|
||
|
||
- `max_idle_connections` `(int: 0)` - Specifies the maximum number of idle
|
||
connections to the database. A zero uses the value of `max_open_connections`
|
||
and a negative value disables idle connections. If larger than
|
||
`max_open_connections` it will be reduced to be equal.
|
||
|
||
- `max_connection_lifetime` `(string: "0s")` - Specifies the maximum amount of
|
||
time a connection may be reused. If <= 0s connections are reused forever.
|
||
|
||
- `username` `(string: "")` - The root credential username used in the connection URL.
|
||
|
||
- `password` `(string: "")` - The root credential password used in the connection URL.
|
||
|
||
### Sample Payload
|
||
|
||
```json
|
||
{
|
||
"plugin_name": "mysql-database-plugin",
|
||
"allowed_roles": "readonly",
|
||
"connection_url": "{{username}}:{{password}}@tcp(127.0.0.1:3306)/",
|
||
"max_open_connections": 5,
|
||
"max_connection_lifetime": "5s",
|
||
"username": "root",
|
||
"password": "mysql"
|
||
}
|
||
```
|
||
|
||
### Sample Request
|
||
|
||
```
|
||
$ curl \
|
||
--header "X-Vault-Token: ..." \
|
||
--request POST \
|
||
--data @payload.json \
|
||
http://127.0.0.1:8200/v1/database/config/mysql
|
||
```
|
||
|
||
## Statements
|
||
|
||
Statements are configured during role creation and are used by the plugin to
|
||
determine what is sent to the database on user creation, renewing, and
|
||
revocation. For more information on configuring roles see the [Role
|
||
API](/api/secret/databases/index.html#create-role) in the database secrets engine docs.
|
||
|
||
### Parameters
|
||
|
||
The following are the statements used by this plugin. If not mentioned in this
|
||
list the plugin does not support that statement type.
|
||
|
||
- `creation_statements` `(list: <required>)` – Specifies the database
|
||
statements executed to create and configure a user. Must be a
|
||
semicolon-separated string, a base64-encoded semicolon-separated string, a
|
||
serialized JSON string array, or a base64-encoded serialized JSON string
|
||
array. The '{{name}}' and '{{password}}' values will be substituted.
|
||
|
||
- `revocation_statements` `(list: [])` – Specifies the database statements to
|
||
be executed to revoke a user. Must be a semicolon-separated string, a
|
||
base64-encoded semicolon-separated string, a serialized JSON string array, or
|
||
a base64-encoded serialized JSON string array. The '{{name}}' value will be
|
||
substituted. If not provided defaults to a generic drop user statement.
