Install Tenable Nessus on Linux

Caution: If you install a Tenable Agent, Tenable Nessus Manager, or Tenable Nessus scanner on a system with an existing Tenable Agent, Tenable Nessus Manager, or Tenable Nessus scanner running nessusd, the installation process terminates all other nessusd processes. You may lose scan data as a result.

Note: Tenable Nessus does not support using symbolic links for /opt/nessus/.
