Tarball assisted install of the infrastructure agent for Linux

With the assisted install of the infrastructure agent for Linux, you can make the changes you need to the installation script and configuration file we provide so you can adapt it to your environment.

Before installation, check the compatibility and requirements.

Install the agent

To install the agent:

1. Download the packaged agent file or use the following command that automatically fetches a specific version of the agent, its checksum and verifies it after download. Replace ARCH=amd64 with desired architecture (amd64, 386, arm64, arm) and V=1.27.4 with latest or specific version.

   bash

   Copy

   $
   V=1.27.4 ARCH=amd64; echo "https://download.newrelic.com/infrastructure_agent/binaries/linux/${ARCH}/newrelic-infra_linux_${V}_${ARCH}.tar.gz" | { read    url; wget "${url}"{,.sum}; shasum -a 256 --check ${url##*/}.sum; }

   From version 1.27.4 on, we provide the tar.gz package GPG signature. You can check the signature procedure and instructions for verification in the infra-agent repository on GitHub.

2. Unpack the file.

3. Make sure the file unpacks with the following structure:

   newrelic-infra
   |-- config_defaults.sh
   |-- etc
   |   |-- init_scripts
   |   |   |-- systemd
   |   |   |   `-- newrelic-infra.service
   |   |   |-- sysv
   |   |   |   `-- newrelic-infra
   |   |   `-- upstart
   |   |       `-- newrelic-infra
   |   `-- newrelic-infra
   |       `-- integrations.d
   |-- installer.sh
   |-- usr
   |   `-- bin
   |       |-- newrelic-infra
   |       |-- newrelic-infra-ctl
   |       `-- newrelic-infra-service
   `-- var
       |-- db
       |   `-- newrelic-infra
       |       |-- custom-integrations
       |       |-- integrations.d
       |       |-- LICENSE.txt
       |       `-- newrelic-integrations
       |-- log
       |   `-- newrelic-infra
       `-- run
           `-- newrelic-infra

   Copy

4. Update your license key in config_defaults.sh.

5. Optional: Update any other environment parameters in the configuration file.

6. Execute installer.sh with admin rights.

The script automatically identifies your service manager. If it fails, it will prompt you to manually update it.

Configure your installation

The configuration file config_defaults.sh serves as a source of reference for all the configuration options. It contains the following environment parameters:

/var/db/newrelic-infra/

/usr/local/bin

/etc/newrelic-infra.yml

/var/run/newrelic-infra/newrelic-infra.log

ROOT

/var/run/newrelic-infra/newrelic-infra.pid

/etc/newrelic-infra/integrations.d/

What's next?

You may also want to:

• Add custom attributes to annotate your infrastructure data.
• Connect your AWS account if your servers are hosted on Amazon EC2.
• Enable log forwarding.
• Add other infrastructure integrations to collect data from external services.
• Manually start, stop, restart, or check the agent status.
