Our PHP agent auto-instruments your code so you can start monitoring applications. Follow this procedure to install New Relic's PHP agent for APM using Amazon Linux 2, RedHat, or CentOS on x86_64 architecture. For installation on aarch64 architecture, please use [tar file](https://docs.newrelic.com/docs/php/php-agent-installation-tar-files) method. **Exception:** If you have an earlier version installed, [upgrade the agent](https://docs.newrelic.com/docs/agents/php-agent/installation/upgrading-php-agent) instead.

## Install the agent [#install]

Even though the package name for New Relic's PHP agent refers to PHP 5, the package works for all [supported PHP versions](https://docs.newrelic.com/docs/agents/php-agent/getting-started/php-agent-compatibility-requirements#php-release).

1.  Make sure you have your license key accessible.
2.  Add the new RPM key
    ```bash
    rpm --import https://download.newrelic.com/php_agent/NEWRELIC_RPM_BD2E199C.public
    ```
3.  Use either of the following ways to obtain the installation package:

    **Tell the package manager (`rpm`) about the New Relic repository**

    ````bash
    sudo rpm -Uvh http://yum.newrelic.com/pub/newrelic/el5/x86_64/newrelic-repo-5-4.noarch.rpm
    ```

    ````

    **Download the rpm file from New Relic**

    -   ```
        newrelic-php5-common-X.X.X.X-1.noarch.rpm
        ```

    -   ```
        newrelic-daemon-X.X.X.X-1.x86_64.rpm
        ```

    -   ```
        newrelic-php5-X.X.X.X-1.x86_64.rpm
        ```
4.  Install the agent and daemon using your preferred package manager:

    **yum**

    ````bash
    sudo yum install newrelic-php5
    ```

    The first time you install New Relic for PHP, yum prompts you to accept the New Relic public key. New Relic's key ID is `548C16BF`.

    ````

    **rpm**

    Replace `X.X.X.X` with the most recent [PHP agent version number](https://docs.newrelic.com/docs/release-notes/agent-release-notes/php-release-notes) when you run this command:

    ````bash
    rpm -i newrelic-php5-common-X.X.X.X-1.noarch.rpm newrelic-daemon-X.X.X.X-1.x86_64.rpm newrelic-php5-X.X.X.X-1.x86_64.rpm
    ```

    ````

    **tarball**

    If **yum** and **rpm** do not work with your host config, [install from the binary tarball](https://docs.newrelic.com/docs/php/php-agent-installation-tar-files).
5.  Run the `newrelic-install` script and follow the instructions.

    ```bash
    sudo newrelic-install install
    ```
6.  Restart your web server (Apache, NGINX, PHP-FPM, etc.).
7.  Generate traffic to your application, and wait a few minutes for it to send data to New Relic. Then, [check your app's performance in the UI](https://docs.newrelic.com/docs/apm/applications-menu/monitoring/apm-overview-page).
