Linux Installation

Preliminary notes

Before you begin the installation, please ensure that the system requirements are met.

If the MetaDefender Storage Security installer package dependencies are not installed on your system the installer will attempt to automatically download them over the internet.

Acquire the package

In order to acquire the package please visit https://www.opswat.com/solution

Info

To limit the required resources, use the ENABLED_MODULES and the DISABLED_SERVICES environment variables in the customer.env file to select which modules to install when deploying MetaDefender Storage Security, you can follow these steps:

Locate the customer.env file in your MetaDefender Storage Security deployment. This file contains environment variables used for customization.
Open the customer.env file in a text editor.
Add the ENABLED_MODULES environment variable to the file. The variable should be in the format ENABLED_MODULES=<module_list>, where <module_list> is a comma-separated list of the modules you want to enable. For example, if you want to enable modules Amazon S3, Google Cloud, and Azure Blob storage units, your customer.env file should include the following line: ENABLED_MODULES=azureblob,amazonsdk,googlecloud
Save the customer.env file.
Proceed with the deployment of MetaDefender Storage Security.

Please note that an online installation involves downloading the required docker images from Docker Hub. If image pulls fail, you may have reached Docker Hub's rate limits, especially when multiple services pull from the same IP address.

To address this, please consider one of the following solutions:

Use docker login to increase your pull limit
Implement image caching or registry proxies
Stagger deployments to avoid concurrent pulls

Advanced installation

We recommend that production deployments use an external database and ensure that web traffic is encrypted. For detailed information on how to configure an external database or HTTPS see advanced installation section:

Debian / Ubuntu package (.deb)

Update your packages

sudo apt update

Install the necessary package dependencies

sudo apt install jq curl gnupg-agent software-properties-common

Move to the folder containing the installer and install it

sudo dpkg -i <name of the file>.deb

After the installation is completed, check if everything went fine

man mdss

or using the help menu

sudo mdss -h

Run the following command in order to initialize MetaDefender Storage Security

sudo mdss -u init

Start the service

sudo mdss -c start

Optionally, you can check the status using the following command:

sudo mdss -c status

Open a browser and navigate to the web interface http://<server> to configure your deployment.

Red Hat Enterprise Linux / CentOS package (.rpm)

Info

Please note that Docker Engine is officially supported only on RHEL s390x architecture, but you may be able to install it manually following the CentOS installation steps: https://docs.docker.com/engine/install/centos/

Update your packages

sudo yum -y update

Move to the folder containing the installer and install it

sudo yum install -y <name of the file>.rpm

After the installation is completed, check if everything went fine

sudo man mdss

or using the help menu

sudo mdss -h

Run the following command in order to initialize MetaDefender Storage Security

sudo mdss -u init

Note: If you don’t have docker already installed, the installer will do that for you, but you will be prompted to sign out and sign back in. This is necessary because your current user needs to be added to the docker group.

Start the service

sudo mdss -c start

Optionally, you can check the status using the following command:

sudo mdss -c status

Open a browser and navigate to the web interface http://<server> to configure your deployment.
If you are using firewall (on CentOS8 and RHEL 8) you may need to update it’s policies:

# Check what interface docker is using, e.g. 'docker0' ip link show # Check available firewalld zones, e.g. 'public' sudo firewall-cmd --get-active-zones # Check what zone the docker interface it bound to, most likely 'no zone' yet sudo firewall-cmd --get-zone-of-interface=docker0 # So add the 'docker0' interface to the 'public' zone. Changes will be visible only after firewalld reload sudo nmcli connection modify docker0 connection.zone public # Masquerading allows for docker ingress and egress (this is the juicy bit) sudo firewall-cmd --zone=public --add-masquerade --permanent # Optional open required incomming ports (wasn't required in my tests) # sudo firewall-cmd --zone=public --add-port=443/tcp # Reload firewalld sudo firewall-cmd --reload # Reload dockerd sudo systemctl restart docker

Podman Configuration

MDSS can also run using the Podman container engine instead of the default Docker one on RHEL operating systems. Podman, podman-docker and docker-compose need to be installed and running before installing MDSS.

After the installation is complete, MDSS needs to be configured to skip the checks for the default Docker engine. This is done by setting SKIP_DOCKER_CHECKS=yes in the /etc/mdss/customer.env file. The following commands can be used to install Podman and MDSS on RHEL.

# install podman, podman-docker and docker-compose sudo yum install podman sudo yum install podman-docker sudo curl -SL https://github.com/docker/compose/releases/download/v2.15.1/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose sudo chmod +x /usr/local/bin/docker-compose sudo systemctl enable podman.socket sudo systemctl start podman.socket # disable SELinux temporarily setenforce 0 # to disable selinux permanetly 'SELINUX=disabled' needs to be set in the following config file sudo vim /etc/selinux/config # install additional MDSS dependencies sudo subscription-manager repos --enable codeready-builder-for-rhel-8-$(arch)-rpms sudo yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm sudo yum install lvm2 sudo yum install wget # install MDSS sudo rpm -i mdss-3.3.2-1.noarch.rpm # edit customer.env and add SKIP_DOCKER_CHECKS=yes sudo vim /etc/mdss/customer.env # start MDSS sudo mdss -c start
