In this comprehensive tutorial, we’ll take you through the entire process of installing and fine-tuning osTicket on Debian 11 Bullseye. osTicket is a robust open-source support ticket system that has garnered a significant following, as evidenced by its presence on GitHub. Being built on PHP, osTicket requires a MySQL database to function. We will cover all the necessary steps, including server setup, firewall configuration, obtaining an HTTPS certificate through Certbot, downloading and setting up osTicket, as well as configuring MariaDB and Nginx.
Prerequisites for Installation
Before we dive into the installation of osTicket, make sure you have the following ready:
- A server with Debian 11 Bullseye, preferably hosted by a service like Vultr.
- Elevated privileges with a sudo user.
- A DNS A record pointing your chosen domain name to the IP address of your server.
Detailed Installation Instructions
Step 1: Installing Necessary Packages
Begin by installing the core components required to run osTicket using the APT package manager:
$ sudo apt install -y ufw nginx python3-certbot-nginx php-fpm php-mysql mariadb-server unzip php-gd php-imap php-xml php-mbstring php-intl php-apcu
Step 2: Fire Up the Firewall
Set up UFW to allow necessary ports for SSH, HTTP, and HTTPS traffic:
$ sudo ufw allow ssh
$ sudo ufw allow http
$ sudo ufw allow https
$ sudo ufw enable
Step 3: Obtain an HTTPS Certificate via Certbot
Secure your osTicket installation with an HTTPS certificate by using Certbot with the Nginx plugin:
$ sudo certbot –nginx -d yourdomain.com
Step 4: Certificate Renewal Automation
Set up a cron job to keep your HTTPS certificate from expiring by renewing it regularly:
$ sudo crontab -e
Paste in the new line to renew automatically:
0 0 * * * /usr/bin/certbot renew –quiet
Step 5: Acquiring osTicket Source
Fetch the latest osTicket source files and prepare them for the server environment:
$ sudo wget -P /var/www/ https://github.com/osTicket/osTicket/releases/latest/download/osTicket-v1.15.4.zip
$ sudo unzip /var/www/osTicket-v1.15.4.zip -d /var/www/
$ sudo mv /var/www/upload /var/www/osticket
$ sudo cp /var/www/osticket/include/ost-sampleconfig.php /var/www/osticket/include/ost-config.php
$ sudo chown -R www-data:www-data /var/www/osticket
Step 6: Database Configuration for MariaDB
Secure your MariaDB installation and set up a dedicated database and user for osTicket:
$ sudo mysql_secure_installation
$ sudo mysql
CREATE DATABASE osticketdb CHARACTER SET utf8 COLLATE utf8_general_ci;
CREATE USER ‘osticketuser’@’localhost’ IDENTIFIED BY ‘yourpassword’;
GRANT ALL PRIVILEGES ON osticketdb.* TO ‘osticketuser’@’localhost’;
FLUSH PRIVILEGES;
EXIT;
Step 7: Configuring Nginx for osTicket
Adjust your Nginx server block for optimal performance with osTicket:
$ sudo nano /etc/nginx/sites-available/osticket
Replace the existing configuration with an optimized one, ensuring you substitute ‘yourdomain.com’ with your actual domain name:
server {
listen 443 ssl http2;
server_name yourdomain.com;
ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem;
root /var/www/osticket;
index index.php;
…
}
Conclusion
