Step-by-step tutorials for server deployment, security, and configuration.
Set up SSH key-based authentication for enhanced security. Generate your SSH key pair locally and add your public key to the server's authorized_keys file. This eliminates the need for password-based authentication and provides better security.
Configure iptables or ufw to control incoming and outgoing traffic. Set up rules to allow only necessary ports and services. Block all other traffic by default to minimize your attack surface.
Install and configure Nginx or Apache web server. Set up virtual hosts to serve multiple domains from a single server. Configure SSL/TLS certificates using Let's Encrypt for secure HTTPS connections.
Install MySQL, PostgreSQL, or MongoDB for your application data storage needs. Configure secure root passwords, create application-specific database users, and set up regular automated backups.
Install Docker and Docker Compose to run containerized applications. Set up docker networks, volumes, and security configurations. Deploy multi-container applications with docker-compose for easy management.
Configure system monitoring tools to track server performance, resource usage, and uptime. Set up alerts for critical events such as high CPU usage, disk space issues, or service failures.
