Tengine Architecture

Tengine, as an open-source web server, is built on a modular architecture that allows for flexibility and customization. Its architecture is designed to handle high-performance web traffic and provide a robust platform for web applications.

Tengine’s architecture comprises several key components and subsystems that work together to process requests and deliver content. These components interact in a well-defined manner, ensuring efficient and reliable operation.

Modules

Tengine’s modular architecture is one of its key strengths. It allows for flexibility and extensibility by providing a mechanism for adding new features and functionalities. Modules are self-contained units that perform specific tasks, such as handling specific protocols, managing connections, or implementing security features.

• Core Modules: These modules are essential for the basic operation of Tengine. They include modules for handling HTTP requests, managing connections, and providing basic security features.
• Extension Modules: These modules provide additional functionalities, such as support for different protocols, caching mechanisms, and load balancing.
• Third-Party Modules: Tengine’s ecosystem also includes a wide range of third-party modules developed by the community, which offer even more specialized features.

Subsystems

Tengine’s architecture is also organized into various subsystems that handle specific aspects of its operation. These subsystems interact with each other to ensure smooth and efficient processing of requests.

• Event Handling: This subsystem is responsible for managing events, such as incoming connections, request processing, and error handling. It uses an event-driven model to handle multiple requests concurrently.
• Request Processing: This subsystem handles the processing of incoming HTTP requests. It parses the request headers, routes the request to the appropriate module, and handles the response generation.
• Connection Management: This subsystem manages the connections between Tengine and clients. It handles connection establishment, data transmission, and connection termination.
• Configuration Management: This subsystem manages the configuration of Tengine, including the definition of modules, server settings, and virtual hosts.

Data Flow

The flow of data in Tengine’s architecture follows a well-defined path. When a client initiates a connection to the server, the event handling subsystem receives the request and triggers the request processing subsystem. The request processing subsystem parses the request headers, routes the request to the appropriate module, and handles the response generation. The response is then sent back to the client through the connection management subsystem.

• Client Request: A client initiates a request to the Tengine server.
• Event Handling: The event handling subsystem receives the request and triggers the request processing subsystem.
• Request Processing: The request processing subsystem parses the request headers, routes the request to the appropriate module, and handles the response generation.
• Module Execution: The appropriate module handles the request and generates the response.
• Response Generation: The response is generated and sent back to the client through the connection management subsystem.
• Client Response: The client receives the response from the Tengine server.

Tengine Installation and Configuration

Tengine is a high-performance web server that offers enhanced features and performance compared to its predecessor, Nginx. Installing and configuring Tengine is relatively straightforward, and this section provides a comprehensive guide to ensure smooth implementation.

Installing Tengine on Different Operating Systems

Installing Tengine on various operating systems is facilitated by its availability as a pre-built package or through source code compilation.

• Ubuntu/Debian: Installing Tengine on Ubuntu or Debian systems is a simple process. The following commands can be used:

  “`bash
  sudo apt-get update
  sudo apt-get install tengine
  “`

  This will download and install the latest stable version of Tengine from the official repositories.

• CentOS/RHEL: For CentOS or RHEL systems, the installation process is similar to Ubuntu/Debian. Use the following commands:

  “`bash
  sudo yum update
  sudo yum install tengine
  “`

  This will fetch and install Tengine from the EPEL (Extra Packages for Enterprise Linux) repository. If the EPEL repository is not already enabled, it can be enabled using the following command:

  “`bash
  sudo yum install epel-release
  “`

• macOS: Installing Tengine on macOS can be achieved using Homebrew, a popular package manager. Use the following command:

  “`bash
  brew install tengine
  “`

  This will install the latest version of Tengine from Homebrew’s repositories.

• Windows: Tengine can also be installed on Windows using the official Tengine binaries. Download the appropriate binary package for your system from the Tengine website and follow the installation instructions provided in the package. Alternatively, you can use a virtualization solution like Docker to run Tengine on Windows.

Configuring Tengine

Tengine’s configuration is handled through the `tengine.conf` file, typically located in `/etc/tengine/` directory. This file contains directives that define the server’s behavior, including virtual host configurations, access control, caching, and more.

• Virtual Hosts: Tengine allows you to host multiple websites on a single server by defining virtual hosts. Each virtual host is defined using a `server` block, which contains directives specific to that website. The following is an example of a virtual host configuration:

  “`
  server
  listen 80;
  server_name example.com www.example.com;

  root /var/www/example.com/public_html;

  index index.html index.htm index.php;

  location /
  try_files $uri $uri/ /index.php?$args;

  location ~ \.php$
  fastcgi_pass unix:/var/run/php-fpm.sock;
  fastcgi_index index.php;
  fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  include fastcgi_params;

  “`

  This configuration defines a virtual host for the domain `example.com` and `www.example.com`. The `listen` directive specifies the port on which the server listens for connections, `server_name` defines the domain name, `root` specifies the document root directory, `index` defines the default index files, and `location` blocks define specific rules for different URLs.

• Access Control: Tengine provides directives to control access to your website. The `allow` and `deny` directives can be used to specify allowed and denied IP addresses or ranges. The following example restricts access to a specific IP address:

  “`
  location /admin
  allow 192.168.1.10;
  deny all;

  “`

  This configuration restricts access to the `/admin` directory to the IP address `192.168.1.10`.

• Caching: Tengine supports caching mechanisms to improve performance. The `proxy_cache` directive enables caching for proxied content, while the `fastcgi_cache` directive enables caching for content generated by FastCGI applications. The following example demonstrates caching for proxied content:

  “`
  location /images/
  proxy_cache images_cache;
  proxy_cache_valid 20m;

  “`

  This configuration enables caching for the `/images/` directory for 20 minutes. The `proxy_cache_valid` directive specifies the cache validity period.

• Performance Tuning: Tengine offers a range of directives for performance optimization. The `worker_processes` directive specifies the number of worker processes, `worker_connections` specifies the maximum number of connections per worker process, and `keepalive_timeout` specifies the duration of the keep-alive connection. Adjust these parameters based on your server’s resources and traffic patterns.
• Security: Tengine includes security features to protect your website. The `ssl` directive enables SSL/TLS encryption for secure communication. The `ssl_certificate` and `ssl_certificate_key` directives specify the SSL certificate and key files. The following example demonstrates SSL configuration:

  “`
  server
  listen 443 ssl;
  server_name example.com www.example.com;

  ssl_certificate /etc/tengine/ssl/example.com.crt;
  ssl_certificate_key /etc/tengine/ssl/example.com.key;

  # … other directives …

  “`

  This configuration enables SSL for the domain `example.com` and `www.example.com`, using the specified certificate and key files.

Best Practices for Configuring Tengine

Following best practices ensures optimal performance and security for your Tengine server.
