# How to install Castopod?

Castopod was thought-out to be easy to install. Whether using dedicated or
shared hosting, you can install it on most PHP-MySQL compatible web servers.

## Requirements

- PHP v8.0 or higher
- MySQL version 5.7 or higher or MariaDB version 10.2 or higher
- HTTPS support

### PHP v8.0 or higher

PHP version 8.0 or higher is required, with the following extensions installed:

- [intl](https://php.net/manual/en/intl.requirements.php)
- [libcurl](https://php.net/manual/en/curl.requirements.php)
- [mbstring](https://php.net/manual/en/mbstring.installation.php)
- [gd](https://www.php.net/manual/en/image.installation.php) with **JPEG**,
  **PNG** and **WEBP** libraries.
- [exif](https://www.php.net/manual/en/exif.installation.php)

Additionally, make sure that the following extensions are enabled in your PHP:

- json (enabled by default - don't turn it off)
- xml (enabled by default - don't turn it off)
- [mysqlnd](https://php.net/manual/en/mysqlnd.install.php)

### MySQL compatible database

> We recommend using [MariaDB](https://mariadb.org).

::: warning

Castopod only works with supported MySQL 5.7 or higher compatible databases. It
will break with the previous MySQL v5.6 for example as its end of life was on
February 5, 2021.

:::

You will need the server hostname, database name, username and password to
complete the installation process. If you do not have these, please contact your
server administrator.

#### Privileges

User must have at least these privileges on the database for Castopod to work:
`CREATE`, `ALTER`, `DELETE`, `EXECUTE`, `INDEX`, `INSERT`, `SELECT`, `UPDATE`.

### (Optional) FFmpeg v4.1.8 or higher for Video Clips

[FFmpeg](https://www.ffmpeg.org/) version 4.1.8 or higher is required if you
want to generate Video Clips. The following extensions must be installed:

- **FreeType 2** library for
  [gd](https://www.php.net/manual/en/image.installation.php).

### (Optional) Other recommendations

- Redis for better cache performances.
- CDN for static files caching and better performances.
- e-mail gateway for lost passwords.

## Install instructions

### Pre-requisites

0. Get a Web Server with [requirements](#requirements) installed
1. Create a MySQL database for Castopod with a user having access and
   modification privileges (for more info, see
   [MySQL compatible database](#mysql-compatible-database)).
2. Activate HTTPS on your domain with an _SSL certificate_.
3. Download and unzip the latest [Castopod Package](https://castopod.org/) onto
   the web server if you haven’t already.
   - ⚠️ Set the web server document root to the `public/` sub-folder within the
     `castopod` folder.
4. Add **cron tasks** on your web server for various background processes
   (replace the paths accordingly):

   - For social features to work properly, this task is used to broadcast social
     activities to your followers on the fediverse:

   ```bash
      * * * * * /path/to/php /path/to/castopod/public/index.php scheduled-activities
   ```

   - For having your episodes be broadcasted on open hubs upon publication using
     [WebSub](https://en.wikipedia.org/wiki/WebSub):

   ```bash
      * * * * * /usr/local/bin/php /castopod/public/index.php scheduled-websub-publish
   ```

   - For Video Clips to be created (see
     [FFmpeg requirements](#ffmpeg-v418-or-higher-for-video-clips)):

   ```bash
      * * * * * /path/to/php /path/to/castopod/public/index.php scheduled-video-clips
   ```

   > These tasks run **every minute**. You may set the frequency depending on
   > your needs: every 5, 10 minutes or more.

### (recommended) Install Wizard

1. Run the Castopod install script by going to the install wizard page
   (`https://your_domain_name.com/cp-install`) in your favorite web browser.
2. Follow the instructions on your screen.
3. Start podcasting!

::: info Note

The install script writes a `.env` file in the package root. If you cannot go
through the install wizard, you can
[create and update the `.env` file manually](#alternative-manual-configuration).

## Community packages

If you don't want to bother with installing Castopod manually, you may use one
of the packages created and maintained by the open-source community.

### Install with YunoHost

[YunoHost](https://yunohost.org/) is a distribution based on Debian GNU/Linux
made up of free and open-source software packages. It manages the hardships of
self-hosting for you.

### Install with Docker

If you wish to use Docker to install Castopod, it is possible thanks to
[Romain de Laage](https://mamot.fr/@rdelaage)!

::: info Note

Given high demand for docker, we plan on maintaining an official Castopod Docker
image directly into the Castopod repository.
