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.
You must have an active Internet connection to download the software from the Cloudera repository. Alternatively, you can download the packages from a system with Internet access, copy the files to your server, and follow the Manual Installation instructions in the next section. For more information, contact Cloudera Support.
Data is not accessible during the encryption process. Plan for system downtime during installation and configuration.
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.
These dependent packages are native to most Linux operating systems, and are resolved by your distribution's package manager during installation.
- Updates to glibc and glibc-common
Installation works with gcc, gcc3, and gcc4.
