How to Install Nginx on Web Host


  1. Update the package list: sudo apt update
  2. Install Nginx: sudo apt install nginx
  3. Start the Nginx service: sudo systemctl start nginx
  4. Verify that Nginx is running: sudo systemctl status nginx


  1. Enable the EPEL repository: sudo yum install epel-release
  2. Install Nginx: sudo yum install nginx
  3. Start the Nginx service: sudo systemctl start nginx
  4. Verify that Nginx is running: sudo systemctl status nginx


  1. Download the latest Windows binary package (either the stable or mainline version, depending on your preference).
  2. Extract the contents of the package to a directory of your choice (e.g., C:\nginx).
  3. (Optional) Add the nginx.exe binary to your system PATH variable.
  4. Open a command prompt and navigate to the directory containing the nginx.exe binary.
  5. Start Nginx by running nginx.exe.

After installing Nginx, you can access the default Nginx web page by visiting http://localhost in your web browser. You can also configure Nginx to serve your own web pages by modifying the default configuration file (/etc/nginx/nginx.conf on Linux, or C:\nginx\conf\nginx.conf on Windows) and adding your own server blocks.


Nginx system requirements

Operating System:

Nginx can run on various operating systems, including:

  1. Linux: Most modern Linux distributions, such as Ubuntu, Debian, Fedora, CentOS, and openSUSE
  2. macOS: macOS 10.9 (Mavericks) and later
  3. Windows: Windows 7, 8, and 10, Windows Server 2008 R2 and later
  4. Other Unix-based systems: FreeBSD, OpenBSD, AIX, Solaris, etc.

Hardware Requirements:

Nginx has low hardware requirements and can run on modest hardware. However, the actual requirements depend on the traffic volume and server load. Here are some general guidelines:

  1. CPU: A modern x86 or x64 processor (multi-core recommended for high-traffic sites)
  2. RAM: At least 512 MB (1 GB or more recommended for high-traffic sites)
  3. Disk Space: At least 100 MB for the Nginx installation (more space required for log files and cached content)

Software Requirements:

Nginx has minimal software requirements and can run on most modern systems. Here are some common software dependencies:

  1. OpenSSL: Nginx requires OpenSSL for SSL/TLS support.
  2. PCRE: Nginx uses the PCRE library for regular expression support.
  3. zlib: Nginx uses the zlib library for compression support.
  4. libxml2/libxslt: Nginx uses these libraries for XML processing.

Most of these dependencies are typically pre-installed on modern operating systems, but may require installation on some older systems.

Keep in mind that these requirements are for the Nginx server itself and don’t include the requirements for the applications and services you deploy on the server.
