Install Invoice Ninja on a Debian 7 VPS

In this tutorial we’ll see how to install Invoice Ninja on a Debian 7 (Wheezy) VPS with MariaDB, PHP-FPM and Nginx. Invoice Ninja is a free, open-source solution for invoicing and billing customers and it’s based on Laravel 4.1 framework. This guide should work on other Linux VPS systems as well but was tested and written for Debian 7 VPS.

Login to your VPS via SSH

ssh user@myVPS

Update the system and install necessary packages

user@myVPS:~# sudo apt-get update && sudo apt-get -y upgrade
user@myVPS:~# sudo apt-get install python-software-properties git curl openssl vim

Install MariaDB 10.0

user@myVPS:~# sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xcbcb082a1bb943db
user@myVPS:~# sudo add-apt-repository 'deb http://mirror.jmu.edu/pub/mariadb/repo/10.0/debian wheezy main'
user@myVPS:~# sudo apt-get update
user@myVPS:~# sudo apt-get install mariadb-server

When the installation is complete, run the following command to secure your installation:

mysql_secure_installation

Next, we need to create a database for our Invoice Ninja instance.

mysql -uroot -p
MariaDB [(none)]> CREATE DATABASE ininja;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON ininja.* TO 'ininjauser'@'localhost' IDENTIFIED BY 'ininjauser_passwd';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> \q

Install and configure PHP and Nginx

The latest versions of Nginx 1.6.2 and PHP 5.6 are not available via the default Debian repositories, so we will add the Dotdeb repository. Open the /etc/apt/sources.list file and append the following lines:

user@myVPS:~# sudo vim /etc/apt/sources.list

deb http://packages.dotdeb.org wheezy all
deb http://packages.dotdeb.org wheezy-php56 all

Next, fetch and install the GnuPG key:

user@myVPS:~# wget -qO - http://www.dotdeb.org/dotdeb.gpg | sudo apt-key add -

Update the system and install Nginx, PHP and all necessary extensions:

user@myVPS:~# sudo apt-get update
user@myVPS:~# sudo apt-get install nginx php5-fpm php5-cli php5-mcrypt php5-gd php5-curl
user@myVPS:~# sudo php5enmod mcrypt

Install Composer

Composer is a dependency manager for PHP with which you can install packages. Composer will pull in all the required libraries and dependencies that you need for your project.

user@myVPS:~# curl -sS https://getcomposer.org/installer | php
user@myVPS:~# sudo mv composer.phar /usr/local/bin/composer

Install Invoice Ninja

Create a root directory for your application.

user@myVPS:~# mkdir -p ~/your_ininja_site

Clone the project repository from GitHub:

user@myVPS:~# git clone https://github.com/hillelcoren/invoice-ninja.git ~/your_ininja_site
user@myVPS:~# cd  ~/your_ininja_site

Install all dependencies:

user@myVPS:~# composer install --no-dev -o

Set the environment to production:

user@myVPS:~# cp bootstrap/environment.default.php bootstrap/environment.php

user@myVPS:~# vim bootstrap/environment.php

Open the database.php file and edit the database settings:

user@myVPS:~# vim app/config/database.php

       'mysql' => array(
            'driver'    => 'mysql',
            'host'      => 'localhost',
            'database'  => 'ininja',
            'username'  => 'ininjauser',
            'password'  => 'ininjauser_passwd',
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
        ),

Run database migrations and seed the database with sample data:

user@myVPS:~# php artisan migrate
user@myVPS:~# php artisan db:seed

Generate a new application key:

user@myVPS:~# php artisan key:generate

user@myVPS:~# vim app/config/app.php

'key' => 'iL7OD2fbvjJvIcSgalLThFaEM4gPtPNF',

Configure Nginx and PHP

Create a new PHP-FPM pool for your user:

user@myVPS:~# sudo nano /etc/php5/fpm/pool.d/your_user.conf

[your_user]
user = your_user  
group = your_user  
listen = /var/run/php5-fpm-your_user.sock  
listen.owner = your_user
listen.group = your_user  
listen.mode = 0666  
pm = ondemand  
pm.max_children = 5  
pm.process_idle_timeout = 10s;  
pm.max_requests = 200  
chdir = /  

Do not forget to change your_user with your username.

Restart PHP-FPM

user@myVPS:~# sudo service php5-fpm restart

Generate SSL certificate:

user@myVPS:~# sudo mkdir -p /etc/nginx/ssl
user@myVPS:~# cd /etc/nginx/ssl
user@myVPS:~# sudo openssl genrsa -des3 -passout pass:x -out ininja.pass.key 2048
user@myVPS:~# sudo openssl rsa -passin pass:x -in ininja.pass.key -out ininja.key
user@myVPS:~# sudo rm ininja.pass.key
user@myVPS:~# sudo openssl req -new -key ininja.key -out ininja.csr
user@myVPS:~# sudo openssl x509 -req -days 365 -in ininja.csr -signkey ininja.key -out ininja.crt

Next, create a new Nginx server block:

user@myVPS:~# sudo vim /etc/nginx/sites-available/your_ininja_site

server {
    listen      443 default;
    server_name your_ininja_site;

    ssl on;
    ssl_certificate     /etc/nginx/ssl/ininja.crt;
    ssl_certificate_key /etc/nginx/ssl/ininja.key;
    ssl_session_timeout 5m;

    ssl_ciphers               'AES128+EECDH:AES128+EDH:!aNULL';
    ssl_protocols              TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;

    root /home/your_user/your_ininja_site/public;

    index index.html index.htm index.php;

    charset utf-8;

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

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log  /var/log/nginx/ininja.access.log;
    error_log   /var/log/nginx/ininja.error.log;

    sendfile off;

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm-your_user.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_intercept_errors off;
        fastcgi_buffer_size 16k;
        fastcgi_buffers 4 16k;
    }

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

server {
    listen      80;
    server_name your_ininja_site;

    add_header Strict-Transport-Security max-age=2592000;
    rewrite ^ https://$server_name$request_uri? permanent;
}

Do not forget to change your_user with your username.

Activate the server block by creating a symbolic link and restart Nginx:

user@myVPS:~# sudo ln -s /etc/nginx/sites-available/your_ininja_site /etc/nginx/sites-enabled/your_ininja_site
user@myVPS:~# sudo /etc/init.d/nginx restart
