Choosing Between a Stable or a Mainline Version
If you're considering installing Nginx on your server, one of the first decisions you'll need to make is whether to choose the stable version or the mainline version. While both versions offer the powerful capabilities of Nginx, there are a few differences that you should be aware of.
The stable version of Nginx is recommended for production servers. It includes critical bug fixes and has been thoroughly tested for reliability and stability. However, it may not have all the latest features that are available in the mainline version. If your primary concern is stability and you don't need the newest features, then the stable version is the way to go.
If you're looking to take advantage of the latest features and functionality, you may want to consider the mainline version. This version includes all the latest updates and enhancements, but it may also include some experimental modules. While these modules can offer exciting new capabilities, they may not be as thoroughly tested as the stable version.
Key Points:
- The stable version is recommended for production servers.
- The stable version includes critical bug fixes and offers reliability.
- The mainline version includes the latest features but may have experimental modules.
- The mainline version is suitable for those who want the latest updates and are willing to accept some level of risk.
Choosing Between a Prebuilt Package and Compiling from Source
When it comes to installing Nginx, you have two main options: using a prebuilt package or compiling from source. Each method has its advantages and it's important to understand the differences before making a decision.
If you're looking for a quick and easy installation, a prebuilt package is the way to go. These packages come with Nginx and all the necessary dependencies bundled together, making the installation process straightforward. It's a great option for beginners or those who want to get up and running quickly.
On the other hand, if you're a more advanced user or have specific requirements, compiling Nginx from source provides more flexibility. This method allows you to customize the installation by adding specific modules or applying the latest security patches. While it requires more technical knowledge, it gives you full control over the configuration of your Nginx server.
Ultimately, the choice between a prebuilt package and compiling from source depends on your individual needs and preferences. If you prioritize simplicity and ease of installation, go for the prebuilt package. If you value customization and control, opt for compiling from source. Whichever method you choose, you'll be able to enjoy the power and versatility of Nginx.
Installing a Prebuilt Package
Installing Nginx from a prebuilt package is a simple and efficient way to get started with this powerful web server. The prebuilt package includes almost all official Nginx modules, making it easy to set up and configure for your specific needs. Here are the steps to install Nginx using a prebuilt package:
- First, update your package manager by running the command:
sudo apt update. - Once the package manager is updated, you can install Nginx by running the command:
sudo apt install nginx. - After the installation is complete, you can start Nginx by running the command:
sudo systemctl start nginx. - To ensure that Nginx starts automatically on system boot, run the command:
sudo systemctl enable nginx.
That's it! You have successfully installed Nginx using a prebuilt package. You can now access your web server by entering your server's IP address or domain name in a web browser. If everything is set up correctly, you should see the default Nginx welcome page.

Modules Included in a Prebuilt Package
When you install Nginx from a prebuilt package, you not only get the web server itself but also a range of modules that enhance its functionality. These modules are included in the package and are ready to use out of the box. Here are some key modules that you can expect to find in a prebuilt package:
- HttpCoreModule: This module provides the core functionality of the HTTP server, handling requests and responses.
- HttpAccessModule: With this module, you can control access to your server by setting up access restrictions and authentication.
- HttpProxyModule: This module allows Nginx to act as a forward proxy and handle proxying requests to upstream servers.
- HttpRewriteModule: By using this module, you can rewrite or redirect URLs based on specific conditions or rules.
- HttpSSLModule: This module enables SSL and TLS support, allowing secure connections between the client and the server.
These are just a few examples of the modules included in a prebuilt Nginx package. Depending on the package and version you choose, there may be additional modules available. You can refer to the official Nginx website or documentation for a comprehensive list of modules included in each package.
Customization with Additional Modules
If the prebuilt package does not include a specific module you require, don't worry! Nginx also allows you to add custom modules by compiling from source. This gives you the flexibility to tailor your Nginx installation to meet your specific needs and requirements. Just make sure to follow the instructions provided by Nginx for compiling and adding the desired modules.
Remember, when choosing between a prebuilt package and compiling from source, consider the trade-offs between convenience and flexibility. If the prebuilt package includes all the modules you need, it can save you time and effort. However, if you require additional modules that are not bundled with the prebuilt package, compiling from source may be the way to go.
