Install Devo Relay on a Red Hat or CentOS box
We recommend installing Devo Relay on Ubuntu. However, it is possible to install it on other Unix-family systems. These instructions are based on a CentOS system using the yum package manager.
If you are using an old version of Devo Relay and want to migrate to the most recent version (v2.0.0), go here to learn how to do it.
Before you begin
Make sure you can provide a machine with the requirements specified in this article.
Before starting with the installation process, you must disable SELinux. See this article to learn how to do it.
Installing Devo Relay
Follow these instructions to install the .deb package that contains the relay.
A note about the keyboard layout
The default installation loads the US keyboard layout. To change the layout for another region, issue the
loadkeys command before starting this procedure. Use the region code for your region. In this example, we are loading the Spanish keyboard layout (es).
sudo loadkeys es
Important: Java versions
Please note that the devo-ng-relay and CLI require Java 8 to work. Other Java versions are not supported. The devo-ng-relay package includes this required Java version (Java 8) so please consider uninstalling any other version you may have, or use the Linux command update-alternatives to make Java 8 the default Java.
Create the devo.repo file in /etc/yum.repos.d/ with the following contents:
[devo] baseurl = http://packages.devo.com/rpms gpgcheck = 1 gpgkey = http://packages.devo.com/PublicKey name = Devo Inc. packages
Update the resources list.
sudo yum-config-manager --enable devo
Install the relay package and the relay command-line interface (CLI) using this command:
sudo yum install devo-ng-relay
Optionally, you can install the devo-monitor package that installs scripts that monitor machine status (CPU, memory, IO traffic) so their values can be sent to the Devo endpoint. The events collected by this package will be available in the
box.stat.unix.*tables of your Devo domain. You can install this package using the following command:
sudo yum install devo-monitor
It is highly recommended to install the devo-monitor package on your machine since it will help in case you need troubleshooting your relay.
Now you must configure your relay and then activate it on the Devo platform. See the Devo Relay setup process in Set up your relay.
You can relaunch the set up process at any time after the installation if needed.
