Configure the OpenVPN Client before using VPN services of the BMR cluster. This section introduces how to configure the OpenVPN Client on Mac OS X, Linux, and Windows operating systems.

Mac OS X

Mac OS X (10.11.2) is taken as an example to describe the following operation steps:

1. Download Tunnelblick installation files. Official website: https://github.com/Tunnelblick/Tunnelblick/releases/tag/v3.8.0. Download address: https://bmr.bj.bcebos.com/tools/openvpn/mac/Tunnelblick_3.8.0_build_5370.dmg.
2. Install Tunnelblick tools. Choose the default installation.
3. Download OpenVPN Client configuration files. Log in to the console, select “Product Service” -> “Baidu MapReduce-Cluster List”, enter the cluster list page, click the cluster name to enter the cluster details page, and click and download “openvpn-conf.zip” in the "Tools Download" section.
4. Decompress the “openvpn-conf.zip” files, and then enter the directory “openvpn-conf/client/”. After the double click of “client.ovpn”, Tunnelblick launches the OpenVPN Client installation configurations, as the following figure shows. Select to share the configurations to "All Users" or "Just Me".
5. Click "Connect" at the lower right after Tunnelblick completes the OpenVPN Client installation configurations.
6. Open the browser, and then use the Master node’s private IP to access cluster services. Obtain the private IP from the "Node Information" section of the cluster details page.

Linux (centos6.5)

Centos 6.5 is taken as an example.
