Linux DSN Configuration
This section describes how to set up ODBC connectivity and configure DSNs on several Linux distributions: Debian-based systems, like Ubuntu, and Red Hat Linux platforms, like Red Hat Enterprise Linux (RHEL), CentOS, and Fedora.
Minimum Linux Versions
Here are the minimum supported versions for Red Hat-based and Debian-based systems:
| OS | Min. Version |
| Ubuntu | 11.04 |
| Debian | 7 |
| RHEL | 6.9 |
| CentOS | 6.9 |
| Fedora | 13 |
| SUSE | 12.1 |
Installing the Driver Dependencies
Run the following commands as root or with sudo to install the necessary dependencies:
- Debian/Ubuntu:
apt-get install libc6 libstdc++6 zlib1g libgcc1
- RHEL/CentOS/Fedora:
yum install glibc libstdc++ zlib libgcc
Here are the corresponding libraries required by the driver:
| Debian/Ubuntu Package | RHEL/CentOS/Fedora Package | File |
| libc6 | glibc | linux-vdso.1 |
| libc6 | glibc | libm.so.6 |
| libc6 | glibc | librt.so.1 |
| libc6 | glibc | libdl.so.2 |
| libc6 | glibc | libpthread.so.0 |
| libc6 | glibc | libc.so.6 |
| libc6 | glibc | ld-linux-x86-64.so.2 |
| libstdc++6 | libstdc++ | libstdc++.so.6 |
| zlib1g | zlib | libz.so.1 |
| libgcc1 | libgcc | libgcc_s.so.1 |
Installing the Driver
You can use standard package management systems to install the driver.
On Debian-based systems, like Ubuntu, run the following command with root or sudo:
dpkg -i /path/to/driver/setup/MailChimpODBCDriverforUnix.deb
On systems that support the RPM package format, run the following command with root or sudo:
rpm -ivh /path/to/driver/MailChimpODBCDriverforUnix.rpm
Licensing the Driver
Run the following commands to license the driver. To activate a trial, omit the <key> input.
cd /opt/cdata/cdata-odbc-driver-for-mailchimp/bin/
sudo ./install-license.sh <key>
Connecting through the Driver Manager
The driver manager loads the driver and passes function calls from the application to the driver. You need to register the driver with the driver manager and you define DSNs in the driver manager's configuration files.
The driver installation registers the driver with the unixODBC driver manager and creates a system DSN. The unixODBC driver manager can be used from Python and from many other applications. Your application may embed another driver manager.
Creating the DSN
See Using unixODBC to install unixODBC and configure DSNs. See Using the DataDirect Driver Manager to create a DSN to connect to OBIEE, Informatica, and SAS.
Connecting to Mailchimp
Mailchimp supports the following authentication methods:
- APIKey
- OAuth
API Key
The easiest way to connect to Mailchimp is to use the API Key. The APIKey grants full access to your Mailchimp account. To obtain the APIKey, log into Mailchimp and click Account -> Extras -> API Keys. You can then set the connection property APIKey to this value.
- AuthScheme: Set this to APIKey.
OAuth
An alternative method to authenticate to Mailchimp is using OAuth standard. OAuth can be used to enable other users to access their own data. To authenticate using OAuth, you need to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL by registering an app with Mailchimp. OAuth requires the authenticating user to interact with Mailchimp using the browser.
- AuthScheme: Set this to OAuth.
Installing Dependencies for OAuth Authentication
The OAuth authentication standard requires the authenticating user to interact with Mailchimp, using a web-browser. If the first OAuth interaction is to be done on the same machine the driver is installed on, for example, a desktop application, the driver needs access to the xdg-open program, which opens the default browser.
To satisfy this dependency, install the corresponding package with your package manager:
| Debian/Ubuntu Package | RHEL/CentOS/Fedora Package | File |
| xdg-utils | xdg-utils | xdg-open |
Set the Driver Encoding
The ODBC drivers need to specify which encoding to use with the ODBC Driver Manager. By default, the CData ODBC Drivers for Unix are configured to use UTF-16 which is compatible with unixODBC, but other Driver Managers may require alternative encoding.
Alternatively, if you are using the ODBC driver from an application that uses the ANSI ODBC API it may be necessary to set the ANSI code page. For example, to import Japanese characters in an ANSI application, you can specify the code page in the config file '/opt/cdata/cdata-odbc-driver-for-mailchimp/lib/cdata.odbc.mailchimp.ini':
[Driver]
AnsiCodePage = 932
