# MariaDB

You can use the MariaDB connector from the CData Sync application to capture data
from MariaDB and move it to any supported destination. To do so, you need to add
the connector, authenticate to the connector, and complete your connection.

## Add the MariaDB Connector

To enable Sync to use data from MariaDB, you first must add the
connector, as follows:

<ol>
  <li>Open the **Connections** page of the Sync dashboard.</li>
  <li>Click **Add Connection** to open the **Select Connectors** page.</li>
  <li>Click the **Sources** tab and locate
  the **MariaDB** row.</li>

  <li>
    Click the **Configure Connection** icon at the end of that row to open
    the **New Connection** page. This action opens the
    **Add Connection** dialog.

    **Note:** If the **Configure Connection** icon is not
    available, click the **Download Connector** icon to install
    the MariaDB connector.
  </li>

  <li>Enter a name for your connection in the **Add Connection** dialog.</li>
  <li>Click **Add** to open the **Settings** tab for your connector.</li>
</ol>

For more information about installing new connectors, see
[Connections](https://docs.sync.cdata.com/26.4/en/connections/connections.md).

## Authenticate to MariaDB

After you add the connector, you need to set the required properties.

* **Server:** Enter the host name or the IP address of your server.
* **Port:** Enter the port for the MariaDB database. The default port value is **3306**.

CData Sync supports authenticating to MariaDB in several ways. Select your authentication method below to proceed to the relevant section that contains the authentication details.

* [**Password**](#password) (default)
* [**NTLM**](#ntlm)
* [**Azure Active Directory**](#azure-active-directory)
* [**Azure Password**](#azure-password)
* [**Azure Managed Service Identity**](#azure-managed-service-identity)
* [**LDAP**](#ldap)

### Password

To connect with your user credentials, set the following properties:

<ul><li>**Auth Scheme:** Select **Password**.</li>
<li>**User:** Enter the username that you use to authenticate to your MariaDB account.</li>
<li>**Password:** Enter the password that you use to authenticate to your MariaDB account.</li></ul>

### NTLM

To connect with NTLM user credentials, specify the following properties:

* **Auth Scheme:** Select **NTLM**.
* **Domain:** Enter the domain name for your Microsoft Windows (NTLM) login.
* **NTLM Version:** Select the version for you NTLM. The default version is **1**.

### Azure Active Directory

To connect with your Azure Active Directory credentials, specify the following properties:

* **Auth Scheme:**  Select **AzureAD**.
* **Azure Tenant:** Enter the Microsoft Online tenant to which you want to connect. If you do not specify a tenant, CData Sync uses the default tenant.
* **OAuth Client Id:** Enter the client Id that you were assigned when you registered your application with an OAuth authorization server.
* **OAuth Client Secret:** Enter the client secret that you were assigned when you registered your application with an OAuth authorization server.

### Azure Password

To connect with an Azure password, specify these settings:

* **Auth Scheme:** Select **AzurePassword**.
* **Azure Tenant:** Enter the identifier (Id) of the Azure Tenant under which your OAuth and client applications were created. This Id is available under **Directory (tenant) ID** on the **Overview** page of one of the applications.

### Azure Managed Service Identity

To leverage Azure Managed Service Identity (MSI) when CData Sync is running on an Azure
virtual machine, select **Azure MSI** for **Auth Scheme**. No
additional properties are required.

### LDAP

To connect with LDAP credentials, specify the following properties:

<ul><li>**Auth Scheme:** Select **LDAP**.</li>
<li>**User:** Enter the username that you use to authenticate to your MariaDB account.</li>
<li>**Password:** Enter the password that you use to authenticate to your MariaDB account.</li></ul>

## Complete Your Connection

To complete your connection:

1. Specify these properties:
   * (Optional) **Database:** Enter the name of the MariaDB database.
   * **Use SSL:** Select whether you want to enable Secure Sockets Layer (SSL). By default, the **Enable** checkbox is not selected.
2. Define advanced connection settings on the **Advanced** tab. (In most cases, though, you should not need these settings.)
3. If you authenticate with AzureAD, click **Connect to MariaDB** to connect to your MariaDB account.
4. Click **Create & Test** to create your connection.

## Enable Binary Logging (for Change Data Capture)

Change data capture (CDC) is enabled automatically for the MariaDB database. However, you must enable binary logging for MariaDB replication. *Binary logs* record transaction updates so replication tools can generate changes. You need the following prerequisites in order to enable binary logging:

* a MariaDB server
* the appropriate MariaDB user privileges

### Enable Binary Logging

1. Determine whether binary logging is enabled by submitting the following statement from a MariaDB prompt:

   ```
   SHOW VARIABLES LIKE 'log_bin';
   ```

   If the option is not enabled (that is, your receive an `OFF` message), configure the following options in the MariaDB Server configuration file:

   ```
   server-id         = 223344
   log_bin           = mariadb-bin
   binlog_format     = ROW
   binlog_row_image  = FULL
   expire_logs_days  = 10
   ```

   Descriptions of these options are available in [MariaDB Binary-Logging Configuration Properties](#mariadb-binary-logging-configuration-properties).

2. Verify that binary logging is enabled by resubmitting this statement:

   ```
   SHOW VARIABLES LIKE 'log_bin';
   ```

### MariaDB Binary-Logging Configuration Properties

This section describes the values for options that are used earlier in step 1:

* `server-id`: This value is a unique Id for each server and each replication client in the MariaDB cluster.
* `log_bin`: The value for this option is the base name of the sequence of binlog files.
* `binlog_format`: The format value for this option is must be set either to `ROW` or `row`.
* `binlog_row_image`: The value for this option must be set to `FULL` or `full`.
* `expire_logs_days`: This value is the number of days before the binlog file is removed automatically. The default value is `0`, which means that there is no automatic removal. Set the value to match the needs of your environment.
