## Install instructions
0. Create a MySQL database for Castopod with a user having access and
modification privileges (for more info, see
[Web Server Requirements](#web-server-requirements)).
1. Download and unzip the Castopod package onto the web server if you havent
already.
- ⚠️ Set the web server document root to the `public/` sub-folder.
2. ⚠️ For broadcasting social activities to the fediverse, add a cron task on
your web server to run every minute (replace the paths accordingly):
```php
* * * * * /path/to/php /path/to/castopod/public/index.php scheduled-activities
```
3. Run the Castopod install script by going to the install wizard page
(`https://your_domain_name.com/cp-install`) in your favorite web browser.
4. Follow the instructions on your screen.
All done, start podcasting!
### (optional) Manual configuration
Before uploading Castopod files to your web server:
1. Rename the `.env.example` file to `.env` and update the default values with
your own.
2. Upload the Castopod files with `.env`
3. Go to `/cp-install` to finish the install process.
## Web Server Requirements
### PHP v7.3 or higher
PHP version 7.3 or higher is required, with the following extensions installed:
- [intl](http://php.net/manual/en/intl.requirements.php)
- [libcurl](http://php.net/manual/en/curl.requirements.php)
- [mbstring](http://php.net/manual/en/mbstring.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](http://php.net/manual/en/mysqlnd.install.php)
### MySQL compatible database
> We recommend using [MariaDB](https://mariadb.org)
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:
`ALTER`, `DELETE`, `EXECUTE`, `INDEX`, `INSERT`, `SELECT`, `UPDATE`.
### (Optional) Other recommendations
- Redis for better cache performances.
- CDN for better performances.
- e-mail gateway for lost passwords.
## Security concerns
Castopod is built on top of Codeigniter, a PHP framework that encourages
[good security practices](https://codeigniter.com/user_guide/concepts/security.html).
To maximize your instance safety and prevent any malicious attack, we recommend
you update all your Castopod files permissions (after installation to avoid any
permission error):
- `writable/` folder must be **readable** and **writable**.
- `public/media/` folder must be **readable** and **writable**.
- any other file must be set to **readonly**.
For instance, if you are using Apache or NGINX with Ubuntu you may do the
following:
```bash
sudo chown -R root:root /path/to/castopod
sudo chown -R www-data:www-data /path/to/castopod/writable
sudo chown -R www-data:www-data /path/to/castopod/public/media
```
