In this post, we will show you how to install InvoiceNinja on Oracle Linux 8.

Step 1 – Install Apache, MariaDB, and PHP

First, you will need to install the Apache and MariaDB service on your system. You can install both packages using the following command:

dnf install httpd mariadb-server -y

Next, you will need to install the latest version of PHP on your server.

First, reset the default PHP module with the following command:

dnf module reset php

Next, install the EPEL and PHP Remi repositories with the following command:

dnf install epel-release  -y
dnf install dnf-utils http://rpms.remirepo.net/enterprise/remi-release-8.rpm

Next, enable the PHP 8.1 repository with the following command:

dnf module enable php:remi-8.1

Next, install PHP with other required extensions using the following command:

dnf install php php-{cli,fpm,gd,mbstring,curl,zip,xml,pdo,mysqlnd,pear,bcmath,gmp,json} --nogpgcheck

Next, start and enable the Apache, MariaDB, and PHP-FPM services with the following command:

systemctl start httpd mariadb php-fpm
systemctl enable httpd mariadb php-fpm

Step 2 – Create a Database for InvoiceNinja

InvoiceNinja uses MariaDB/MySQL as a database backend, so you will need to create a database and user for InvoiceNinja.

First, log in to the MariaDB shell with the following command:

mysql

Next, create a database and user with the following command:

CREATE DATABASE invoiceninja;
GRANT ALL ON invoiceninja.* TO invoiceninja@localhost IDENTIFIED BY "password";

Next, flush the privileges and exit from the MariaDB shell with the following command:

FLUSH PRIVILEGES;
EXIT;

Step 3 – Install InvoiceNinja

First, you will need to install Composer on your server. You can install it with the following command:

curl -sS https://getcomposer.org/installer -o composer-setup.php
php composer-setup.php --install-dir=/usr/local/bin --filename=composer

Once Composer is installed, verify the Composer version using the following command:

composer -V

You will get the following output:

Composer version 2.4.2 2022-09-14 16:11:15

Next, download the latest version of InvoiceNinja with the following command:

git clone -b v5-stable --single-branch https://github.com/invoiceninja/invoiceninja.git

Once the download is completed, move the downloaded file to the Apache web root:

mv invoiceninja /var/www/html/ninja

Next, change the directory to the InvoiceNinja and install all required dependencies:

cd /var/www/html/ninja
composer create-project --no-dev

Next, edit the .env file and define your database settings:

nano .env

Change the following lines:

DB_HOST=localhost
DB_DATABASE=invoiceninja
DB_USERNAME=invoiceninja
DB_PASSWORD=password
DB_PORT=3306

Save and close the file, then set proper permissions and ownership to the InvoiceNinja directory:

chown -R apache:apache /var/www/html/ninja
chmod -R 755 /var/www/html/ninja/storage/

Step 4 – Configure Apache for InvoiceNinja

Next, you will need to create an Apache virtual host configuration file for InvoiceNinja. You can create it with the following command:

nano /etc/httpd/conf.d/invoice-ninja.conf

Add the following lines:

<VirtualHost *:80>
    ServerName ninja.example.com
    DocumentRoot /var/www/html/ninja/public

    <Directory /var/www/html/ninja/public>
       DirectoryIndex index.php
       Options +FollowSymLinks
       AllowOverride All
       Require all granted
    </Directory>

    CustomLog /var/log/httpd/invoice_ninja_access.log combined
    ErrorLog /var/log/httpd/invoice_ninja_error.log
</VirtualHost>

Save and close the file, then restart the Apache service to apply the changes:

systemctl restart httpd
