Nginx Multiple Server Blocks With Domain
What is Nginx?
Nginx is a web server software that can be used for a variety of tasks. It is a lightweight, open source software that can be used for web hosting, content delivery, directory services, security, and other web-based applications. It is also used to improve the load speed of web pages and optimize web traffic by caching content.
Nginx’s open source nature makes it extremely extensible, allowing users to customize and expand its features and applications. It is also highly stable, and can be managed and monitored via a simple web-based user interface, making it a great tool for managing and maintaining complex web applications.
What are Server Blocks?
Server blocks are the term used to describe the configuration section of Nginx where information about each web server and virtual host is defined. They provide Nginx with the details necessary to route requests to the correct systems. Each server block defines a logical server, and can be used to assign a domain name to it, as well as provides IP address restrictions, setting a default server, and other related settings.
Differences Between Nginx and Apache Server Blocks?
The main difference between Nginx and Apache server blocks is that Nginx uses a different syntax to define configuration values. Apache uses the traditional Apache .htaccess file, while Nginx uses the Nginx configuration format. Both systems allow for virtual hosts, but the commands used to define these differ between the two.
Another difference is that Nginx does not have a separate configuration file for each virtual host, as Apache does. This means that when using Nginx, all server blocks are defined in the same configuration file, making it easier to manage multiple virtual hosts.
Configuring Nginx Server Blocks
Nginx server blocks can be configured using two methods: via a web interface or via a text configuration file. The web interface allows for basic server block configuration and requires no programming experience. The text file method requires knowledge of the Nginx configuration syntax and allows for more complex configuration.
The most basic configuration includes specifying the server name, the server root (DocumentRoot), and the file path for the server log files. To assign a domain to a server block, the server_name directive must be used. For example:
server_name example.com www.example.com
If there are multiple virtual hosts that need to be configured, each virtual host must have its own server block with the corresponding domain for the server_name directive.
Using Nginx Multiple Server Blocks with Domain
Using Nginx to host multiple domains is a very simple process. All that needs to be done is to create multiple server blocks and point each one to a different domain. Each server block should be configured in a similar way with the only difference being the server name.
For each server block, set the server name to the domain you want to use to access it. Then define the server root, the server log file paths, and any other settings that are applicable. Once all the settings have been configured, the server blocks are ready to use.
Now that the server blocks are configured, any requests with a matching domain name will be routed to the appropriate server block. Multiple server blocks can be used in Nginx to provide access to multiple domains.
Server Blocks and SSL/TLS Certificates
In order to provide secure access to a website via SSL/TLS, Nginx server blocks must be configured with SSL/TLS certificates. These certificates are used to encrypt the communication between the client and the server, ensuring that the data is kept secure. Certificates can be generated for free with Let’s Encrypt or purchased from one of the many vendors that offer SSL/TLS certificates.
In order to configure Nginx with a certificate, the SSL/TLS module must be enabled and configured with the SSL/TLS certificate file. In a server block, the ssl_certificate and ssl_certificate_key directives should be used to point Nginx to the appropriate certificate file. Once the SSL/TLS module is enabled and configured, the server block is ready to accept requests that are encrypted with SSL/TLS.

Q: How do I use Nginx to host multiple domains?
A: To use Nginx to host multiple domains, create multiple server blocks and point each one to a different domain. Each server block should be configured in a similar way with the only difference being the server name.
Q: How do I configure SSL/TLS certificates with Nginx?
A: To configure SSL/TLS with Nginx, the SSL/TLS module must be enabled and configured with the SSL/TLS certificate file. In a server block, the ssl_certificate and ssl_certificate_key directives should be used to point Nginx to the appropriate certificate file.
Using Nginx server blocks is an effective way to manage multiple web sites and virtual hosts. Nginx server blocks can be easily configured with domain names and SSL/TLS certificates and configured for optimal performance and security. By using Nginx, web developers can create complex web applications and deploy them quickly and securely.
