Install NV for Load Generator on Linux

This section describes how to install and uninstall NV for Load Generator on a Linux machine.

Note:  

  • Starting from NV 2023 R1, NV for Load Generator is no longer supported on Linux machines.

  • NV Insights is not supported for tests run on Linux.

Installation prerequisites

To install the prerequisites:

  1. Install Oracle Java JRE or Azul Zulu OpenJDK if not already installed. For supported versions, see System requirements.

    Note:  

    • For NV 2022 R2 and later, you must install Zulu OpenJDK 11 on your Linux machines that are running NV, and update the Java default path to Zulu 11.

    • For distributions that support NV, see the relevant version of the Supported Protocols guide available from Support Matrix.

    Zulu

    Install from repository (including dependencies)

    Red Hat/Oracle Enterprise Linux:

    1. Download the zulu.repo file from:
      http://repos.azulsystems.com/rhel/zulu.repo

    2. Copy:

      cp zulu.repo /etc/yum.repos.d/

    3. Install Zulu:

      NV versions earlier than 2022 R2:

      yum install zulu-8

      NV 2022 R2 and later:

      yum install zulu-11

      ln -sf /usr/lib/jvm/zulu-11/ default

    Ubuntu: 

    apt-add-repository 'deb http://repos.azulsystems.com/ ubuntu stable main'

    apt-get update
    apt-get install zulu-8

    Install from package (without dependencies)

    (Useful if the target computer does not have Internet access)

  2. Set the default Java path:

    Zulu

    NV versions earlier than 2022 R2:

    mkdir /usr/java (Only if /usr/java does not exist)

    cd /usr/java

    rm default

    ln -sf /usr/lib/jvm/<zulu-8 package name>/jre default

    NV 2022 R2 and later: Update the Java path to point to Zulu 11 by removing the existing link:

    rm -f /usr/java/default
    Oracle Java

    Confirm the default path:

    readlink -f /usr/java/default/

    Sample output:

    /usr/java/jdk1.8.0_131/jre/

  3. Install GCC:

    • Red Hat/Oracle Enterprise Linux:

      yum install gcc

    • SUSE:

      zypper install gcc

    • Ubuntu:

      apt-get install gcc

  4. Install kernel-devel/linux-headers:

    • Red Hat/Oracle Enterprise Linux:

      yum install -y kernel-devel-$(uname -r)

    • SUSE:

      zypper install kernel-default-devel

    • Ubuntu:

      dpkg -s linux-headers-$(uname -r)

  5. Install the ed line editor on Red Hat/Oracle Enterprise Linux:

    yum install ed

  6. For all Ubuntu distributions that do not include the make command by default—for example, 16.04—install build-essential:

    apt-get install build-essential
