Prepare VPS for Invoice Ninja

Your server should be capable of hosting most PHP applications at this point. But Invoice Ninja has special requirements. It needs PHP’s gmp extension enabled on the server. The Virtualmin installation tutorial doesn’t cover this requirement. Let’s fix that. Execute following command as root user.

apt install php7.0-gmp
Install Composer

Composer is a dependency management tool for PHP. We’ll need it since we’re building Invoice Ninja from Github repository. Following command will install it.

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

Install Invoice Ninja

As I said before, we’re cloning Invoice Ninja from Github repository. This will make sure we’re getting the latest version of software. But before you do that, log out of the root account and login as your domain’s admin user. Then change to home directory.

cd $HOME

Following command will clone Invoice Ninja to your domain’s home directory. It’ll create a directory named invoiceninja in the home directory.

git clone https://github.com/invoiceninja/invoiceninja.git

Navigate to Invoice Ninja directory

cd invoiceninja

Now install Invoice Ninja with Composer,

composer install

Configure Document Root

Virtualmin configure nginx to serve files from public_html directory. But Invoice Ninja serves its public content from its own public directory. As a way around this, we’ll create symlink between public_html directory and Invoice Ninja public directory. Start by removing public_html directory.

rm -rf $HOME/public_html

Create the symlink,

ln -s $HOME/invoiceninja/public $HOME/public_html

This will serve Invoice Ninja public directory content on domain’s public_html directory. We’re almost done. There’s a one last thing we need to take care of.

Configure Nginx for Invoice Ninja

Now we’ll add Nginx rewrite rules for Invoice Ninja. You need to execute these commands as root user. So login to server as root and open Nginx configuration file for the domain with following command.

nano /etc/nginx/sites-available/example.com.conf

Replace example.com with your domain name. Look for following line within the file.

fastcgi_param HTTPS $https;

And paste these rules BELOW that line,

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

Save and close file by hitting Ctrl+X and then Y. Then restart nginx web server,

service nginx restart

Run Invoice Ninja Setup Wizard

Open your domain in the browser to complete the installation. You’ll see a page like below.
Invoice Ninja Setup Wizard

Page has instructions to create a new MySQL database for Invoice Ninja. But you don’t need to do it. Virtualmin already did it for you when you were adding your domain to Virtualmin. You can get MySQL credentials from Virtualmin. Another important setting on setup wizard is Email Settings. I suggest using Mailgun. They have better deliverability in my experience. And there’s a free plan too.

That concludes the instructions to install Invoice Ninja on Ubuntu 16.04 VPS with Virtualmin and Nginx. Create a topic on sysadmin forum if you have issues with the installation.
