Step-by-Step Installation Guide

Note: The specific steps will vary depending on your operating system, application stack, and hosting environment. I’ll provide general guidance and examples for popular setups.

Installing the New Relic Agent

1. Choose the Right Agent:

  • Determine the appropriate New Relic agent for your application stack (PHP, Node.js, Java, Python, etc.).
  • Download the agent from the official New Relic website.

2. Configure the Agent:

  • Unpack the downloaded agent archive.
  • Locate the configuration file (e.g., newrelic.ini for PHP, newrelic.js for Node.js).
  • Replace the placeholder license key with your actual New Relic license.
  • Adjust other configuration settings as needed (refer to the New Relic documentation for specific options).

3. Install the Agent:

  • Follow the platform-specific instructions for installing the agent. This might involve copying files to specific directories, running installation scripts, or using package managers.

    Example: Installing the New Relic PHP Agent

    1

    sudo bash -c "$(curl -Ls https://download.newrelic.com/php_agent/release/install_newrelic.sh)

4. Restart Your Application:

  • Ensure the New Relic agent is loaded by restarting your web server or application.

Verify the Installation

  • Access your New Relic dashboard.
  • Look for your application’s data appearing in the dashboard.
  • Check for any error messages or warnings in the New Relic UI or logs.

Additional Tips:

  • Refer to the official New Relic documentation for detailed instructions specific to your setup.
  • Utilize New Relic’s support resources if you encounter issues.
  • Consider using environment variables or configuration management tools to manage your New Relic license key securely.

Installing the New Relic Agent for PHP

PHP is a widely used language for web development, so let’s provide more detailed instructions for installing the New Relic PHP agent.

Prerequisites:

  • A PHP-enabled web server (Apache, Nginx)
  • Root or sudo access to the server

Steps:

  1. Download the Agent:

    1

    sudo bash -c "$(curl -Ls https://download.newrelic.com/php_agent/release/install_newrelic.sh)"

  2. Configure the Agent:

    • Open the newrelic.ini file located in /etc/php/your_php_version/apache2/mods-available/newrelic.ini (adjust the path according to your PHP version and web server).

    • Replace YOUR_LICENSE_KEY with your actual New Relic license key:

      1

      newrelic.license = "YOUR_LICENSE_KEY"

    • Configure additional settings as needed (refer to the New Relic documentation).

  3. Enable the Agent:

    • Create a symbolic link to enable the module:

      1

      sudo ln -s /etc/php/your_php_version/apache2/mods-available/newrelic.ini /etc/php/your_php_version/apache2/mods-enabled/newrelic.ini

  4. Restart the Web Server:

    • Restart your web server for the changes to take effect:

      1

      sudo systemctl restart apache2

Verification:

  • Access your New Relic dashboard.
  • Look for your PHP application’s data appearing in the dashboard.

Additional Considerations:
