Koel is a simple web-based personal audio streaming app written in Vue on the client side and Laravel on the server side. Koel source code is hosted on Github. This guide will show you how to install Koel on a fresh Fedora 28 Vultr instance by utilizing PHP, MariaDB, Nginx, Node.js, Yarn and Composer.

Requirements

• PHP version 5.6.4 or greater, with the following extensions:
  • OpenSSL
  • PDO
  • Mbstring
  • Tokenizer
  • XML
• MariaDB
• Latest stable version of Node.js with yarn
• Composer
• Nginx

Before you begin

Check the Fedora version.

cat /etc/fedora-release
# Fedora release 28 (Twenty Eight)

Create a new non-root user account with sudo access and switch to it.

useradd -c "John Doe" johndoe && passwd johndoe
usermod -aG wheel johndoe
su - johndoe

NOTE: Replace johndoe with your username.

Set up the timezone.

timedatectl list-timezones
sudo timedatectl set-timezone 'Region/City'

Ensure that your system is up to date.

sudo dnf check-upgrade || sudo dnf upgrade -y

Install necessary packages.

sudo dnf install -y wget curl vim git && sudo dnf groupinstall -y "Development Tools"

For simplicity, disable SELinux and Firewall.

sudo setenforce 0; sudo systemctl stop firewalld; sudo systemctl disable firewalld

Install PHP

Install PHP and required PHP extensions.

sudo dnf install -y php-cli php-fpm php-common php-mysqlnd php-curl php-json php-zip php-xml php-mbstring

Start and enable PHP-FPM.

sudo systemctl start php-fpm.service
sudo systemctl enable php-fpm.service

Install MariaDB and setup database

sudo systemctl enable mariadb.service

Run mysql_secure_installation to improve security and set the password for the MariaDBroot user.

sudo mysql_secure_installation

Connect to MariaDB as the root user.

mysql -u root -p
# Enter password:

Create an empty MariaDB database and user for Koel, and remember the credentials.

CREATE DATABASE dbname;
GRANT ALL ON dbname.* TO 'username' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
EXIT

Install and configure Nginx

Install Nginx.

sudo dnf install -y nginx

Check the version.

nginx -v
# nginx version: nginx/1.12.1

Start and enable Nginx.

sudo systemctl start nginx.service

Configure Nginx. Run sudo vim /etc/nginx/conf.d/koel.conf and populate the file with the following configuration.

server {
  listen 80;
  server_name example.com;
  root /var/www/koel;
  index index.php;


  # Whitelist only index.php, robots.txt, and those start with public/ or api/ or remote
  if ($request_uri !~ ^/$|index\.php|robots\.txt|api/|public/|remote) {
    return 404;
  }

  location /media/ {
    internal;
    # A 'X-Media-Root' should be set to media_path settings from upstream
    alias $upstream_http_x_media_root;
   }

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

   location ~ \.php$ {
     try_files $uri $uri/ /index.php?$args;
     fastcgi_param PATH_INFO $fastcgi_path_info;
     fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;

     fastcgi_pass unix:/run/php-fpm/www.sock;
     fastcgi_index index.php;
     fastcgi_split_path_info ^(.+\.php)(/.+)$;
     fastcgi_intercept_errors on;
     include fastcgi_params;
   }
}

Test Nginx configuration.

sudo nginx -t

Reload Nginx.

sudo systemctl reload nginx.service

Install Node.js

Install Node.js.

curl --silent --location https://rpm.nodesource.com/setup_8.x | sudo bash -
sudo dnf -y install nodejs

Check the version.

node --version
# v8.11.3

Install Yarn

Install Yarn package manager.

curl --silent --location https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
sudo dnf install -y yarn

Check the version.

yarn --version
# 1.9.2

Install Composer

Install Composer.

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '93b54496392c062774670ac18b134c3b3a95e5a5e5c8f1a9f115f203b75bf9a129d5daa8ba6a13e2cc8a1da0806388a8') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
sudo mv composer.phar /usr/local/bin/composer

Check the version.

composer --version
# Composer version 1.6.5 2018-05-04 11:44:59

Install Koel

Create an empty document root folder where Koel will be installed.

sudo mkdir -p /var/www/koel

Navigate to the document root folder.

cd /var/www/koel

Change ownership of the /var/www/koel folder to user johndoe.

sudo chown -R johndoe:johndoe /var/www/koel

Clone the Koel repository to it, checkout the latest tagged release and install its dependencies.

git clone https://github.com/phanan/koel.git .
git checkout v3.7.2
composer install

Run the php artisan koel:init command to setup the database and admin account.

php artisan koel:init

Run vim .env and set APP_URL to your URL.

APP_URL=http://example.com

Run yarn install to compile and install front-end dependencies.

yarn install

NOTE: If you run out of memory, you will receive an error message. To avoid that, you can temporarily stop MariaDB, Nginx and PHP-FPM services, or configure swap memory, if the first solution does not help.

Change ownership of the /var/www/koel directory to nginx.

sudo chown -R nginx:nginx /var/www/koel

Run sudo vim /etc/php-fpm.d/www.conf and set the user and group to nginx. Initially, it will be set to apache.

sudo vim /etc/php-fpm.d/www.conf
# user = nginx
# group = nginx

Restart PHP-FPM.

sudo systemctl restart php-fpm.service

The setup is now complete. To continue, open your domain in a web browser and you will see a login page. Then, login by entering your admin account credentials that you have previously created.
