Important: With the exception of Cloudera Navigator Encrypt, Cloudera Enterprise is supported on platforms with Security-Enhanced Linux (SELinux) enabled. However, policies need to be provided by other parties or created by the administrator of the cluster deployment. Cloudera is not responsible for policy support nor policy enforcement, nor for any issues with them. If you experience issues with SELinux, contact your OS support provider.

Supported command-line interpreters:

• sh (Bourne)
• bash (Bash)
• dash (Debian)

Note: Navigator Encrypt does not support installation or use in chroot environments.

SELinux Requirements

SELinux must be disabled for Key Trustee installation and operation. Modify /etc/selinux/config to set SELINUX=disabled and reboot the system for the change to take effect.

Network Requirements

For new Navigator Key Trustee Server (5.4.0 and higher) installations, Navigator Encrypt initiates TCP traffic over port 11371 (HTTPS) to the Key Trustee Server.

For upgrades and Key Trustee Server versions lower than 5.4.0, Navigator Encrypt initiates TCP traffic over ports 80 (HTTP) and 443 (HTTPS) to the Navigator Key Trustee Server.

Internet Access

You must have an active connection to the Internet to download many package dependencies, unless you have internal repositories or mirrors containing the dependent packages.

Maintenance Window

Data is not accessible during the encryption process. Plan for system downtime during installation and configuration.

Administrative Access

To enforce a high level of security, all Navigator Encrypt commands require administrative (root) access (including installation and configuration). If you do not have administrative privileges on your server, contact your system administrator before proceeding.

Package Dependencies

Navigator Encrypt requires these packages, which are resolved by your distribution package manager during installation:

• dkms
• keyutils
• ecryptfs-utils
• libkeytrustee
• navencrypt-kernel-module
• openssl
• lsof
• gcc
• cryptsetup

These packages may have other dependencies that are also resolved by your package manager. Installation works with gcc, gcc3, and gcc4.
