In this article, we explore how to get proper server management.

What is Server Management?

What is server management

Server management refers to maintaining servers to operate at peak performance. You have to ensure the servers are secure & healthy. It entails a wide range of processes, from server monitoring to optimizing.

The system admins are in charge of managing the server. Some of their duties include:

  • User management & access control
  • Server configuration
  • Server-side software installation & updates
  • Monitoring CPU, RAM, network
  • Creating backups & restoring files
  • Configure security settings like firewalls

The upkeep of servers ensures that your web applications are running smoothly. Maintaining the infrastructure also protects the data & internal systems.

As your business scales, you may need to add new servers. The admins may have to configure (or reconfigure) multiple servers. Managing a server allows flexibility & scalability. It lets you adapt to changes quickly.

Hardware Components

  • CPU

    The CPU is referred to as the brain of the server. It is also known as the processor. CPU usage is an essential metric in server monitoring. You can use it to analyze the processing speed of applications. It’s one of the performance indicators for server & network health.

  • RAM

    Random Access Memory (RAM) acts as the server’s short-term memory. It’s critical for better performance of the server. The amount of RAM you would require for scaling depends on your specific hosting needs. You have to monitor RAM usage to ensure it does not reach total capacity.

  • Hard Drive

    The hard drive acts as the server’s permanent storage. You should monitor the hard drive to avoid it reaching maximum storage capacity.

  • Network/Port

    Network ports act as communication endpoints. Servers are connected to a port with a range of speeds set by the host. Check if you have enough network adaptors & connections for the server.

  • CPU temperature

    The server can heat up very quickly if it’s not managed correctly. You require cooling fans to ensure the physical servers at your data center don’t overheat.

Services Components

  • WAF

    A Web Application Firewall (WAF) protects applications from malicious attacks. These attacks can lead to data loss, hijacked systems, and downtime. A WAF filters and blocks bad HTTP/s traffic to protect your web apps. The admins configure & manage firewall settings for network security.

  • LoadBalancer

    A LoadBalancer helps to distribute incoming network traffic across multiple servers. It improves application performance by decreasing the burden on servers. The load balancer ensures high availability & reliability. The admins have to set up and manage load balancers on servers.

Server-side Software Components

What is Server Management - Server-side software components

The server-side software also has to be maintained regularly. You must know the software dependencies of your infrastructure. Ensure that the software is updated for performance & security.

Some of the common server-side software components:

  • PHP
  • MySQL
  • Operating system
  • NGINX
  • Redis/Varnish

Common Server Management Components

  • DNS

    The Domain Name System (DNS) translates domain names into machine-readable IP addresses. With millions of domain names, the DNS directory can become very large. That’s why the directory is stored & distributed globally using DNS servers. If the DNS server is not configured correctly, your clients cannot reach your website. To manage the DNS, you can use DNS server software or a DNS service provider.

  • Database

    If you use MySQL, the database management is usually done with PHPMyAdmin. You can create & manage database servers. Typical database administration tasks include change management, security, backups & recovery.

  • MySQL

    MySQL is an open-source relational database management system (RDBMS). You can use MySQL commands to import or restore databases. The admins have to start/stop MySQL services, maintain user accounts, update MySQL, etc. Using a modern server control panel, you can automatically upgrade or downgrade the MySQL version (by a script).

  • PHP Management

    PHP is a popular server-side scripting language used for web development. The PHP code is processed on the web server by a PHP interpreter. PHP scripts are only interpreted on the server that has PHP installed. Many hosting servers come with pre-installed PHP versions. Depending on your application, you need to install the right PHP version.

  • Manage SSH/FTP users

    SSH (Secure Shell) is a network protocol for secure communication. It ensures strong encryption & authentication for data integrity. The File Transfer Protocol (FTP) transfers computer files between a client and server on a computer network. You have to create & manage SSH/FTP users. If you are using a server control panel, there is no need to access the server from the terminal.

  • Services

    You may want to restart services if you have modified the services configuration. You can start & stop services quickly using a server control panel. Services include MySQL, Elasticsearch, PHP, NGINX, Redis, Varnish.

  • SSL

    SSL certificates protect sensitive data during transfer. It helps verify your site identity and fulfills compliance requirements. To secure the communication with HTTPS, you should install SSL certificates for all domains. Some server control panels offer to install a free Let's Encrypt certificate.

Server Security Components

What is Server Management - Server security

Hackers are constantly finding new ways to get into your system. It could be from a misconfigured port or an unpatched vulnerability.

You must strengthen your infrastructure to avoid any attacks. Some of the server-side security components include:

  • Web Application Firewall

    A firewall separates your internal network from the external incoming traffic. WAF is application-specific. The admins filter the traffic as well as block/whitelist IPs/bots. It is essential to set up & maintain firewalls to restrict access to your system.

  • Detecting intrusion & threats

    Using intrusion detection systems (IDS), you can detect traffic for threats and any abnormal activities. It scans files moving through the network. It can monitor patterns and flag any suspicious deviations.

  • Regularly upgrade software & OS.

    Your server can have security loops if all the components are not upgraded regularly. Ensure you add security patches, upgrades and use the latest software versions.

  • Set up Access limitations

    You can specify access privileges to networks, files, directories, and other server elements. You can limit read access to specific sensitive data.

  • SSL certificates

    You should install SSL or Let’s Encrypt certificates for server security.

  • Password security

    You should use the best practices for passwords. Set password policies that all the users have to follow. Use minimum character lengths, complexity & password expiry policies. You can also use 2FA and session timeouts.

Configure a Web Server

What is Server Management - Configuring a web server

The system admins will handle the setup & configuration. The web server contains an operating system, web server, database, and scripting language.

One of the popular solution stacks for Linux web servers is the LAMP stack. The components can be interchangeable.

  • Linux for the operating system

    Linux is a free, Unix-like computer operating system. It is lightweight, open-source, and offers high performance.

  • Apache/NGINX as webserver

    Apache HTTP server delivers web content from the server to the web browser. The component is interchangeable with other faster web servers like NGINX.

  • MySQL for database

    MySQL is a free & open-source database engine for websites. It is a multi-threaded SQL database management system.

  • PHP, Perl, or Python programming language

    PHP and its alternatives Perl, Python are programming languages for web development.

Along with these components, you also have to configure Elasticsearch, Redis, and Varnish caching services. You should ensure to meet the system requirements before setting up the server.
