Non-Root Account
  • You can install ArcMC as a root or non-root user. However, when installing as a root user, a non-root user account is needed in order to run some required processes.
    • To create a non-root user:
      1. Run the following command: 

        useradd {non-root user}

      2. Configure the password for the non- root user:

        passwd {non-root user} enter a password

      3. Provide execute permissions for the {ArcSight-ArcMC-3.2.4.Build Number.0.bin} file:

        chmod +x {ArcSight-ArcMC-3.2.4.Build Number.0.bin}

      4. Switch to the non-root user:

        su {non-root user}

      5. Execute the .bin file:

        ./opt/{ArcSight-ArcMC-3.2.4.Build Number.0.bin}

        Follow the on-screen wizard to complete the process.

    • When installing ArcMC as a root user, you can select the port on which it listens for secure web connections (HTTPS). When installing as a non-root user, the port must be configured to 9000. This value cannot be changed and must be externally accessible.

    • If ArcMC is installed as a non-root user, and the host is rebooted, ArcMC services will fail to start automatically. Start them manually with this command:
    • <install_dir>/current/arcsight/arcmc/bin/arcmcd start
    Note: If installed with a non-root account, use an initialization script to launch services automatically.  See Starting Services Automatically for a Non-Root Installation .
    Time Zone Database tzdata-2020a-1.el8.noarch or later is required.
    OS Upgrade
  • Upgrade to a supported operating system before performing the ArcMC installation. Refer to the ArcMC Release Notes, available from the ArcSight Software Marketplace, for the most current information on supported operating systems, supported browsers, and other technical requirements.
