How to Install SabreDAV on Fedora CoreOS Latest

SabreDAV is an open-source WebDAV server that allows you to share files and other resources over the web. In this tutorial, we will show you how to install SabreDAV on Fedora CoreOS latest.

Step 1: Install Required Packages

Open the terminal on your Fedora CoreOS system.
Type the following command to update your system:
```
sudo dnf update
```
Install the required packages by running the following command:
```
sudo dnf install php php-cli php-xml php-pdo php-mysqlnd
```

Step 2: Install SabreDAV

Download the latest version of SabreDAV from the official website https://sabre.io/ into your preferred directory. In this example, we will download it into /opt/sabredav:
```
sudo mkdir /opt/sabredav
sudo wget https://github.com/sabre-io/dav/releases/latest/download/sabre-dav.zip -O /opt/sabredav/sabre-dav.zip
```
Extract the SabreDAV package:
```
sudo unzip /opt/sabredav/sabre-dav.zip -d /opt/sabredav/
```
Note: You may need to install unzip before you can extract the package. You can install it using the following command:
```
sudo dnf install unzip
```
Install the SabreDAV dependencies by running the following command:
```
cd /opt/sabredav/
sudo composer install
```
Note: You may need to install Composer before you can run this command. To install Composer, run the following command:
```
sudo dnf install composer
```

Step 3: Configure SabreDAV

Create a new configuration file:

sudo cp /opt/sabredav/examples/sabre/dav/config.php /opt/sabredav/

Edit the config.php file using your favorite text editor:
```
sudo nano /opt/sabredav/config.php
```

Modify the configuration to suit your needs. You should at least set up the following parameters:

$baseUri = '/'; // your WebDAV URL, e.g. https://example.com/webdav/
$pdo = new \PDO('mysql:dbname=database_name;host=localhost', 'username', 'password');

$authBackend = new \Sabre\DAV\Auth\Backend\PDO($pdo);
$principalBackend = new \Sabre\DAVACL\PrincipalBackend\PDO($pdo);
$carddavBackend = new \Sabre\CardDAV\Backend\PDO($pdo);
$caldavBackend = new \Sabre\CalDAV\Backend\PDO($pdo);

Save the changes and close the file.

Step 4: Start SabreDAV

Start the SabreDAV server by running the following command:
```
php /opt/sabredav/bin/sabredav.php
```

If everything is set up correctly, you should see the following message:

Starting server, listening on 0.0.0.0:8080 and 0.0.0.0:443. You can stop the server by pressing Control-C.

By default, SabreDAV listens on port 8080. You should now be able to access the WebDAV server by navigating to http://<your_ip_address>:8080/ in your browser.
