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 CentOS 7 AKLWEB HOST 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

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.

sudo systemctl enable mariadb.service
Run mysql_secure_installation to improve security and set the password for the MariaDB root 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

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;
# Allow 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_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_intercept_errors on;
include fastcgi_params;
}
}
Test the 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 yum -y install nodejs
Check the version.
node --version
# v8.11.3
Install Yarn
Install the Yarn package manager.
curl --silent --location https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
sudo yum 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;"

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 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.
