• NGINX
• Redis or Varnish
• VeePN for Mac

Common Server Management Components

1. 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.

2. 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.

3. 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).

4. 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.

5. 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.

6. 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.

7. 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

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
• Detecting intrusion & threats
• Regularly upgrade software & OS.
• Set up Access limitations
• SSL certificates
• Password security

Web Server Configuration

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
• Apache/NGINX as webserver
• MySQL for database
• PHP, Perl, or Python programming language

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.

Importance of Effective Server Management

Managing servers reduces downtime & data breaches. It helps to avoid any system failure.

Your server is vulnerable to attacks if it is not managed. Hackers can bypass authentication to gain access to your data. Or even wipe out your data altogether.

The server has to be managed regularly. Otherwise, it can lead to unstable server environments.

The lack of proper server administration affects your business. You could lose potential customers, brand reputation & revenue.
