## Databases

Icinga2 relies on relational databases for many parts of its functionality. **None** of those databases get installed by the roles. You need to install and configure them yourself. For doing so, there are many ways available, e.g. the Ansible role [geerlingguy.mysql](https://galaxy.ansible.com/geerlingguy/mysql) for MySQL flavours (both MySQL and MariaDB) or [geerlingguy.postgresql](https://galaxy.ansible.com/geerlingguy/postgresql) for PostGresQL:

```yaml
- name: Configure databases for Icinga2
hosts: database
vars:
mysql_databases:
- name: icingadb
- name: icingaweb
- name: vspheredb
encoding: utf8mb4
collation: utf8mb4_unicode_ci
- name: director
mysql_users:
- name: icingadb-user
host: localhost
password: icingadb-password
priv: "icingadb.*:ALL"
[...]
roles:
- role: geerlingguy.mysql
```
> [!NOTE]
> Schema migrations needed for the respective Icinga components to work will be handled either by the respective roles or by the Icinga components themselves.

## Database

IcingaDB relies on a relational database to persist received data. This database **won't** be created by this role - you need to deploy and configure one in advance. For more information, see the [Databases](../getting-started.md#databases) section in the getting started guide.

## Module x509

### Variables and Configuration

The general module parameter like `enabled` and `source` can be applied here.

| Variable | Value |
|----------|------------|
| enabled | true/false |
| source | package |

#### Section configuration

The backend database for the module needs to be available and configured at the `icingaweb2_resources` variable.

```
icingaweb2_modules:
x509:
source: package
enabled: true
config:
backend:
resource: x509
```

#### Configure SNI Names.

To configure SNIs for a IP address, use the dictionary `sni`.

Example:

```
icingaweb2_modules:
x509:
source: package
enabled: true
config:
backend:
resource: x509
sni:
192.168.56.213:
hostnames:
- icinga.com
- test2.icinga.com
```

#### Import Certificates

To import certificates use the **list** `certificate_files` all files need to be
available locally beforehand.

```
icingaweb2_modules:
x509:
source: package
enabled: true
config:
backend:
resource: x509
certificate_files:
- /etc/ssl/certs/ca-certificates.crt
```

#### Database Schema Setup

To import the database schema use `database` dictionary with the following variables.

| Variable | Type | Description | Default |
|----------|------|-------------|---------|
| `import_schema` | `Boolean` | Defines wether the schema will be imported or not. | false |
| `host` | `String` | Defines database address to connect to. | `localhost` |
| `port` | `int` | Defines the database port to connect to. | `3306` or `5432` |
| `user` | `string` | Defines database user | `x509` |
| `name` | `String` | Defines the database to connect to. | `x509` |
| `password` | `String` | Defines the database password to connect with. | OMITTED |
| `ssl_mode` | `String` | Clients attempt to connect using encryption, falling back to an unencrypted connection if an encrypted connection cannot be established |**n/a** |
|`ssl_ca`| `String`| Defines the path to the ca certificate for client authentication. | **n/a** |
|`ssl_cert`|`String`| Defines the path to the certificate for client authentication. | **n/a** |
|`ssl_key`| `String` | Defines the path to the certificate key for client key authentication. | **n/a** |
|`ssl_cipher`|`String`| Ciphers for the client authentication. | **n/a** |
|`ssl_extra_options`|`String`| Extra options for the client authentication. | **n/a** |

## Databases

Icingaweb2 and some of its modules rely on a relational database to persist data. These databases **won't** be created by this role - you need to deploy and configure them in advance. For more information, see the [Databases](../getting-started.md#databases) section in the getting started guide.
