Install Invoice Ninja on CentOS 7

In this tutorial, we will show you how to install and configuration of Invoice Ninja on your CentOS 7.

I will show you the step-by-step installation of Invoice Ninja on a CentOS 7 server.

Prerequisites

  • A server running one of the following operating systems: CentOS 7.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Invoice Ninja on CentOS 7

Step 1. First, let’s start by ensuring your system is up-to-date.

yum clean all
yum -y install epel-release
yum -y update

Step 2. Install the LEMP server.

A CentOS 7 LEMP stack server is required. If you do not have a LEMP installed, you can follow our guide here. Also, install the required PHP modules:

yum install install php70w-fpm php70w-cli php70w-pear php70w-gd php70w-xml php70w-curl php70w-gmp php70w-pdo php70w-mysql php70w-zip php70w-mbstring php70w-mcrypt

Once the installation is finished, you will need to modify the php.ini configuration file:

nano /etc/php.ini

Change the following line:

cgi.fix_pathinfo=0

Step 3. Configuring MariaDB for Invoice Ninja.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. you should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB:

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

Next, we will need to log in to the MariaDB console and create a database for the Invoice Ninja. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for Invoice Ninja installation:

MariaDB [(none)]> CREATE DATABASE ninja_db;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON ninja_db.* TO 'ninja'@'localhost' IDENTIFIED BY 'password';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> \q

Step 4. Configure PHP-FPM.

You will need to configure the PHP-FPM pool for Nginx users:

nano /etc/php-fpm.d/www.conf

Change the following lines:

user = nginx
group = nginx
listen = /var/run/php/php-fpm.sock
listen.owner = nginx
listen.group = nginx
listen.mode = 0660
env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp

Save the file and exit from the text editor.

Next, you will need to create a new directory for the PHP session and socket file:

mkdir -p /var/lib/php/session
mkdir -p /var/run/php/
chown -R nginx:nginx /var/lib/php/session/
chown -R nginx:nginx /var/run/php/

Next, start PHP-FPM and enable it to start at boot time using the following commands:

systemctl start php-fpm
systemctl enable php-fpm

Step 5. Installing Invoice Ninja.

The first thing to do is to go to Invoice Ninja’s download page and download the latest stable version of Invoice Ninja:

cd /var/www/html/
git clone https://github.com/hillelcoren/invoice-ninja.git ninja

You need to install composer:

curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/bin --filename=composer

Next, install all the Invoice Ninja dependencies using composer:

cd /var/www/html/ninja
composer install --no-dev -o

Once the installation is done, rename the .env file and make some changes:

mv .env.example .env
nano .env

Change the database values according to your database:

DB_DATABASE=ninja_db
DB_USERNAME=ninja
DB_PASSWORD=Y0urPa55w0rd

Save the file and exit from the text editor. Next, edit the database configuration in the config directory:

nano config/database.php

Change the following lines:

'database'  => env('DB_DATABASE', 'ninja_db'),
'username'  => env('DB_USERNAME', 'ninja'),
'password'  => env('DB_PASSWORD', 'Y0urPa55w0rd'),

Save the file and exit from the text editor and prepare the database with the following command:

php artisan migrate

You will be prompted to run the command, type ‘yes’, and press Enter.

Next, seed the database with all records as shown below:

php artisan db:seed

Run the following command to generate the application key and note this application key:

php artisan key:generate

Next, edit the app.php file with a nano text editor:

nano config/app.php

Add the key as shown below:

'key' => env('APP_KEY', 'y0urGenerated Key'),

Save and close the file and also change some folders permissions:

chown -R nginx:nginx /var/www/html/ninja/

Step 6. Configure Nginx for Invoice Ninja.

Create an SSL Certificate and create a new virtual host configuration for Invoice Ninja:

mkdir -p /etc/nginx/cert/openssl req -new -x509 -days 365 -nodes -out /etc/nginx/cert/ninja.crt -keyout /etc/nginx/cert/ninja.keychmod 600 /etc/nginx/cert/*

Next, create a new virtual host configuration file inside /etc/nginx/ directory:

nano /etc/nginx/conf.d/ninja.conf

Add the following lines:

server {
    listen  80;
    server_name idroot.us;
    add_header Strict-Transport-Security max-age=2592000;
    rewrite ^ https://$server_name$request_uri? permanent;
}

server {
    listen  443 default;
    server_name 192.168.15.23;
    ssl on;
    ssl_certificate     /etc/nginx/cert/ninja.crt;
    ssl_certificate_key /etc/nginx/cert/ninja.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 /var/www/html/ninja/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 and Error Log for Invoice Ninja
    access_log  /var/log/nginx/ininja.access.log;
    error_log   /var/log/nginx/ininja.error.log;

    sendfile off;

    # Handle PHP Applications
    location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/var/run/php/php-fpm.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;
       }
    }

Save and close the file. Restart the Nginx service for the changes to take effect:

systemctl restart nginx

Step 7. Configure FirewallD Invoice Ninja.

Before accessing the Invoice Ninja web interface, you will need to allow HTTP and HTTPS service through firewalld:

firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --add-service=https
firewall-cmd --reload

Step 8. Accessing Invoice Ninja.

Invoice Ninja will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://your-domain.com/ or http://your-server-ip and complete the required steps to finish the installation.
