       SSL_CLIENT_CERT_FILE: "/usr/local/etc/pkg/angie/angie-repo.crt",
       SSL_CLIENT_KEY_FILE:  "/usr/local/etc/pkg/angie/angie-repo.key"
     }' | sudo tee -a /usr/local/etc/pkg.conf > /dev/null
   ```
6. Update the repo indexes:
   ```console
   $ sudo pkg update
   ```
7. Install the Angie PRO package:
   ```console
   $ sudo pkg install -r angie -y angie-pro
   ```
8. (*Optional*) Install any [extra](#install-extras-pro)
   packages you need:
   ```console
   $ sudo pkg install -r angie -y <PACKAGE NAME>
   ```
9. Start the service:
   ```console
   $ sudo service angie start
   ```
10. To autostart Angie PRO after server reboot:
    ```console
    $ sudo sysrc angie_enable=YES
    ```

#### NOTE
Since the FreeBSD package manager may incorrectly determine the latest version,
use the following approach to update already installed packages:

```console
$ sudo pkg upgrade `pkg search -r angie angie-pro-[0-9] | sort -Vr | head -1 | awk {'print $1'}`
```

### openSUSE

1. Create the `/etc/ssl/angie/` directory:
   ```console
   $ sudo mkdir -p /etc/ssl/angie/
   ```
2. Transfer the files you received with your license:

   | File Type   | Original Name    | Where                           |
   |-------------|------------------|---------------------------------|
   | Certificate | `angie-repo.crt` | `/etc/ssl/angie/angie-repo.crt` |
   | Private Key | `angie-repo.key` | `/etc/ssl/angie/angie-repo.key` |

   Then combine them into a bundle `/etc/ssl/angie/angie-repo-bundle.crt`:
   ```console
   $ cat /etc/ssl/angie/angie-repo.crt /etc/ssl/angie/angie-repo.key | \
         sudo tee -a /etc/ssl/angie/angie-repo-bundle.crt > /dev/null
   ```
3. To add the repository, create a file named
   `/etc/zypp/repos.d/angie.repo`
   with the following contents:
   ```ini
   [angie-pro]
   enabled=1
   autorefresh=1
   baseurl=https://download.angie.software/angie-pro/opensuse/$releasever_major?ssl_clientcert=/etc/ssl/angie/angie-repo-bundle.crt&ssl_verify=peer
   gpgcheck=1
   gpgkey=https://angie.software/keys/angie-signing.gpg.asc
   ```
4. Update the repo indexes:
   ```console
   $ sudo zypper refresh
   ```
5. Install the Angie PRO package:
   ```console
   $ sudo zypper install -y angie-pro
   ```
6. (*Optional*) Install any [extra](#install-extras-pro)
   packages you need:
   ```console
   $ sudo zypper install -y <PACKAGE NAME>
   ```
7. Start the service:
   ```console
   $ sudo systemctl start angie
   ```
8. To automatically start Angie PRO after server reboot:
   ```console
   $ sudo systemctl enable angie
   ```

## Extras

In addition to packages that provide core functionality,
we also publish several additional packages,
both our own and from selected third-party sources.

<a id="install-console-light-pro"></a>

### Console Light Web Panel

Console Light is a lightweight
[monitoring web panel](https://en.angie.software//angie/docs/configuration/monitoring.md#monitoring) for Angie PRO,
published in our repositories as the `angie-pro-console-light` package.
It's installed the same way as the `angie` package in the instructions above;
for configuration instructions, see the [Console Light Web Monitoring Panel](https://en.angie.software//angie/docs/configuration/monitoring.md#monitoring) section.

<a id="install-dynamicmodules-pro"></a>

### Dynamic Modules

To extend the basic functionality of Angie PRO,
you can add various dynamic modules.
You can get them as ready-made packages from our repository:

| [angie-pro-module-image-filter](https://en.angie.software//angie/docs/configuration/modules/http/http_image_filter.md#http-image-filter)                                                                                                     | Adds image transformations for JPEG, GIF, PNG, and WebP formats.                                                                   |

| [angie-pro-module-perl](https://en.angie.software//angie/docs/configuration/modules/http/http_perl.md#http-perl)                                                                                                                             | Allows writing `location` and variable handlers in Perl,<br/>as well as calling Perl from SSI.                                     |
| [angie-pro-module-xslt](https://en.angie.software//angie/docs/configuration/modules/http/http_xslt.md#http-xslt)                                                                                                                             | Adds a filter that transforms XML responses using XSLT templates.                                                                  |

To apply an installed module in your [configuration](https://en.angie.software//angie/docs/configuration/configfile.md#configfile),
load it using the [load_module](https://en.angie.software//angie/docs/configuration/modules/core.md#load-module) directive in the `main` context:

```nginx
load_module modules/<module name>.so;
```

A wide range of [third-party modules](https://en.angie.software//angie/docs/installation/external-modules/index.md#install-thirdpartymodules) is also available.

## License File

To configure the license for Angie PRO:

1. Save the license file as `/etc/angie/license.pem`,
   setting the same permissions you use for your
   [client certificates](https://en.angie.software//angie/docs/configuration/ssl.md#ssl-config).
2. Verify the license is valid;
   otherwise, check the details:
   ```console
   $ sudo angie -t

     angie: Valid license found:
     angie:   - owner: CN=Angie Client License
     angie:   - period: Jul  8 21:00:00 2024 GMT .. Jul 17 20:59:59 2024 GMT
     angie:
     angie: Limitations:
     angie:   - worker_processes_limit: 8
     angie:   - worker_connections_limit: 0
   ```
3. Monitor the console and logs for any licensing issues.
   If the license expires during operation,
   Angie PRO periodically issues corresponding warnings.
   Additionally, on reload, configuration error messages will appear
   if, for example, the number of worker processes
   specified in the license terms is exceeded.
4. Modify the `/etc/angie/angie.conf` file;
   after installation, two parameters in it limit operation:
   ```nginx
   worker_processes 1;
   worker_connections 256;
   ```

   After saving the license file,
   change them according to your license terms, for example:
   ```nginx
   worker_processes 8;
   worker_connections 65535;
   ```
