Prerequireds:

• 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.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• 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.

CREATE DATABASE katana;
CREATE USER 'katanauser'@'localhost' IDENTIFIED BY 'PASSWORD';
GRANT ALL PRIVILEGES ON `katana`.* TO 'katanauser'@'localhost';
FLUSH PRIVILEGES;

Step 5. Configuring Apache web server for Sabre/Katana.

Create a new virtual host directive in Apache with the following content:

###nano /etc/httpd/vhosts.d/yourdomain.com.conf

<VirtualHost YOUR_SERVER_IP:80>
ServerAdmin webmaster@yourdomain.com
DocumentRoot "/var/www/html/katana/"
ServerName yourdomain.com
ServerAlias www.yourdomain.com
ErrorLog "/var/log/httpd/yourdomain.com-error_log"

<Directory "/var/www/html/katana/">
DirectoryIndex index.html index.php
