The following procedure is provided to guide UAM administrators in the installation of the solution on Red Hat 7-based hosts. Please review carefully the prerequisites section before starting with the procedure itself.

Prerequisites

Make sure all these prerequisites are met. Otherwise, the installation procedure will fail:

• Ensure the host can connect to public URLs on the Internet.
• Ensure you can access the host through SSH by using its main service IP address. It should also be possible to open an SSH connection from the same host using that IP address.
• Download the Devo UAM software, copy it to your home folder and extract it using:

cd $HOME
tar -zxvf devo-ua-deployer.tgz

...

Installation procedure

1. Check that user configured can run sudo command without prompt. Run the following line in an SSH session where you did not previously run any sudo command:

sudo ls

If the previous command still asks for a password, you can use the next command to avoid it:

sudo /bin/bash -c "echo \"$(whoami) ALL=(ALL:ALL) NOPASSWD: ALL\" >> /etc/sudoers "

2. Install EPEL repository:

wget -O /tmp/epel-release-latest-7.noarch.rpm https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum install /tmp/epel-release-latest-7.noarch.rpm && rm /tmp/epel-release-latest-7.noarch.rpm

3. Install Ansible:

sudo yum install ansible

4. Change the working directory to the path where the installation package was extracted:

cd $HOME/devo-ua-deployer

5. Install the Ansible playbooks' dependencies:

ansible-galaxy install -r playbooks/roles/requirements.yaml

6. Edit the inventories/py2-1host-example.yaml file based the particular requirements of the installation. Refer to the generic deployment guidelines for additional information. If no additional requirements are needed, edit the file by following the next step.

7. Set the following properties under all.hosts.devo-ua-manager yaml section:

• ansible_host: Devo Universal Agent Manager IP.
• ansible_user: User that will run Devo UAM. Same as the user that has been configured previously in sudoers.
• ansible_password: Password
• Enable the packs that you want to deploy, for more info check generic deployment guidelines.
• If you want to use a private key instead of user and password please check the generic deployment guidelines section.

8. Set the following properties under all.vars yaml section:

duam_relay_entrypoint : tcp://FQDN_CENTRAL_RELAY:443. Where FQDN_CENTRAL_RELAY is the FQDN of your central Devo relay : 

• If your domain is deployed in the US Cloud (us.devo.com): tcp://us.elb.relay.logtrust.net:443
• If your domain is deployed in the EU Cloud (eu.devo.com): tcp://eu.elb.relay.logtrust.net:443
• If your domain is deployed in a different cloud, contact your Devo representative to know your entry point.
• To send the data via a Devo Relay instead of sending it directly to Devo check here to find out more.

9. Create docker/user/config.json file with valid empty JSON body:

echo '{}' > docker/user/config.json

10. Run the Ansible playbook:

ansible-playbook -i inventories/py2-1host-example.yaml playbooks/devo-universal-agent.yaml

Once the installation process finishes, you can connect to server app using https://DUAM_IP:8080, where DUAM_IP is the Devo Universal Agent Manager IP. User and password were configured in your inventory file.

Upon agent installation, all monitored endpoints (please refer to Universal Agent Deployment) should be automatically detected and listed as an active host. If the website was already opened before adding the host, a page refresh is required. This is an example screenshot:

Troubleshooting

Use the following commands to verify the status of all the services exposed by the UA Manager:

To check the status port 8080:

systemctl status devo-ua-manager

To check the status port 8081:

systemctl status nginx
