Installing Mono

To use a Linux machine as a VSA proxy, install the Mono framework on an AWS instance running CentOS or RHEL.

Note: For SP17 and more recent service packs, after you install the Virtual Server Agent on a Linux machine and start services, the software checks to see whether Mono is installed and, if necessary, installs the required version of the Mono package. You do not need to install the Mono package manually.

Before You Begin

  • To deploy a Linux machine as a VSA proxy, the machine must run one of the following operating system versions:
    • CentOS 7.4
    • RHEL 7.5
  • To add the Mono repository to your system, execute the commands in a root shell. For more information, see Add the Mono repository to your system.
  • You must install Mono Version 5.16.


  1. Install base packages:

    sudo yum -y groupinstall base

  2. Import the public key that is used to verify the Mono package to install:

    sudo rpm --import "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF"

  3. Add and enable a new yum repository from the specified URL:

    sudo yum-config-manager --add-repo http://download.mono-project.com/repo/centos/

  4. Install Mono 5.16:

    sudo yum -y install mono-complete-

  5. Remove the Mono repository:

    sudo rm /etc/yum.repos.d/download.mono-project.com_repo_centos_.repo

From the CommCell Console, add the Linux machine as a client computer, and then install the Virtual Server Agent and MediaAgent packages.
