How to Install AgenDAV on Fedora CoreOS Latest

AgenDAV is an open-source, multilingual web-based collaborative calendar application that allows you to share calendars, tasks, and contacts. In this tutorial, we will guide you through the process of installing AgenDAV on Fedora CoreOS.

Prerequisites

Before we get started with the installation process, ensure you have the following prerequisites:

A Fedora CoreOS Latest server
A sudo non-root user

Step 1: Install Required Packages

Connect to your Fedora CoreOS server using a secure shell (SSH) client with a sudo non-root user.
Update the system repository and packages by running the following command:
```
sudo dnf update
```

Install the required packages for AgenDAV to function:

sudo dnf install php php-mysqlnd php-fpm php-mbstring php-json nginx mariadb-server wget unzip

Step 2: Download and Extract AgenDAV

Change your directory to /opt:
```
 cd /opt
```

Download the latest version of AgenDAV from the sourceforge website using wget:

sudo wget https://sourceforge.net/projects/agendav/files/agendav/agendav-2.3.1/agendav-2.3.1.zip

Extract the downloaded zip file to your webroot directory:

 sudo unzip agendav-2.3.1.zip -d /usr/share/nginx/html/

Rename the extracted folder to “agendav”:

sudo mv /usr/share/nginx/html/agendav-2.3.1 /usr/share/nginx/html/agendav

Change the ownership of the agendav directory:

sudo chown -R nginx:nginx /usr/share/nginx/html/agendav

Step 3: Configure Nginx

Create a new Nginx server block configuration:
```
sudo vi /etc/nginx/conf.d/agendav.conf
```

Enter the following content to your configuration and save the file:

server {
   listen 80;
   server_name agendav.example.com;
   root /usr/share/nginx/html/agendav/public;

   index index.php;

   location / {
      try_files $uri /index.php$is_args$args;
   }

   location ~ \.php$ {
      fastcgi_pass unix:/var/run/php-fpm/www.sock;
      fastcgi_index index.php;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      include /etc/nginx/fastcgi_params;
   }

   location ~ /\.ht {
      deny all;
   }
}

Note: Replace agendav.example.com with the domain name for your AgenDAV installation.

Test the Nginx configuration for syntax errors:
```
sudo nginx -t
```
Restart the Nginx server to apply the changes:
```
sudo systemctl restart nginx
```

Step 4: Configure MariaDB

Start and enable the MariaDB service:
```
sudo systemctl enable --now mariadb
```
Log in to MariaDB to set a root password and create a new database for AgenDAV:
```
sudo mysql_secure_installation
```
Follow the on-screen prompts to set the root password, remove the anonymous user, disable remote root login, and remove the test database.
Reload the privileges to apply the changes:
```
sudo systemctl reload mariadb
```

Create a new MariaDB database and user for AgenDAV:

sudo mysql -u root -p

CREATE DATABASE agendav;
GRANT ALL PRIVILEGES ON agendav.* TO 'agendavuser'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
exit;

Step 5: Configure PHP

Open the PHP-FPM configuration file:
```
sudo vi /etc/php-fpm.d/www.conf
```
Change the user and group directives to nginx:
```
user = nginx
group = nginx
```
Change the listen directive to unix:/var/run/php-fpm/www.sock:
```
listen = unix:/var/run/php-fpm/www.sock
```
Uncomment the listen.owner and listen.group directives:
```
listen.owner = nginx
listen.group = nginx
```
Uncomment the listen.mode directive and set its value to 0660:
```
listen.mode = 0660
```
Save and close the /etc/php-fpm.d/www.conf configuration file.
Restart the PHP-FPM service to apply the changes:
```
sudo systemctl restart php-fpm
```

Step 6: Access AgenDAV

Open your web browser and navigate to http://agendav.example.com where agendav.example.com is the domain you specified in the Nginx configuration file.
You should see the AgenDAV login page. Enter the admin user credentials to log in ({username: “admin”, password: “admin”}).
Once logged in, proceed to configure the AgenDAV settings.
