Hello! As an experienced AnQiCMS website operator, I am well aware of all aspects of content management and system deployment.AnQiCMS with its efficient and flexible multi-site management capabilities is indeed a powerful tool for small and medium-sized enterprises and content operation teams.In practice, especially when deploying multiple sites, we strongly recommend using a reverse proxy.This is not only a technical practice, but also a key strategy to ensure the long-term stability, security, and efficiency of the system.

Deployment characteristics of AnQiCMS and multi-site requirements

AnQiCMS is a lightweight enterprise-level content management system developed based on the Go language, with its core advantages lying in high performance and ease of deployment.Native Go applications usually listen to a specific network port to provide services, for example, our AnQiCMS listens to the default port 8001.This means that each independent AnQiCMS instance will occupy a port.When we use the powerful multi-site management feature of AnQiCMS, to carry multiple brand websites, sub-sites, or content branches in a single system, although these websites are managed by a single AnQiCMS instance, when accessed externally, we need to use different domain names (such aswww.example.com/blog.example.com/shop.example.comTo distinguish them.

In the absence of a reverse proxy, the port listened to by the AnQiCMS instance is exposed directly (such asexample.com:8001) to access the website, this does not conform to the user habits of the standard port (80/443) of the HTTP/HTTPS protocol, and may also cause port conflicts and management complexity when deploying multiple AnQiCMS instances.It is more important that this will directly expose the real port and architecture of the backend service, posing unnecessary risks to website security.

The core function and advantages of reverse proxy

The reverse proxy plays the role of an 'intelligent intermediary' between the client and the backend server in the network architecture.For AnQiCMS multi-site deployment, reverse proxy can listen to standard HTTP/HTTPS ports (80/443) and intelligently forward requests to AnQiCMS instances running on specific ports based on the client's domain name or path.This means that all external access is unified through a reverse proxy entry, and AnQiCMS itself only needs to focus on content processing, without having to directly face the complex external network environment.

The document mentions multiple times the Nginx or Apache reverse proxy configuration, as well as the recommended reverse proxy settings when deploying AnQiCMS in Docker environments (such as 1Panel or Baota panel), all of which clearly point out the importance of this deployment method.It maps the external domain to the internal AnQiCMS service port, providing a solid foundation for our multi-site architecture.

Enhance website security

Security is always our top priority when operating the website, AnQiCMS itself pays great attention to 'software security' and 'preventing many security issues from occurring.'The reverse proxy plays the role of the first line of defense here. It can hide the real IP address and port of the backend AnQiCMS server, making it difficult for external attackers to directly probe the internal details of the AnQiCMS service, greatly increasing the difficulty of attacks.

In addition, modern reverse proxy software typically integrates advanced security features such as DDoS protection, Web Application Firewall (WAF), and others.They can filter out malicious traffic and potential attacks such as SQL injection, cross-site scripting (XSS), and provide an additional layer of protection for AnQiCMS before the request reaches it.Unified management of SSL/TLS certificates and encrypted communication (HTTPS) at the reverse proxy layer, not only simplifies certificate management, but also offloads the performance burden of encryption and decryption processing by AnQiCMS, while ensuring the security of data transmission for all sites.

Optimize performance and load balancing

The website's access speed directly affects user experience and search engine rankings.Reverse proxy plays a crucial role in performance optimization. It can cache static resources such as website images, CSS stylesheets, and JavaScript files.When the user visits again or multiple users access the same static resource, the reverse proxy can directly return the content from the cache without needing to request AnQiCMS each time, which significantly reduces the load on the backend server, speeds up page loading, and is particularly complementary to AnQiCMS's 'static caching and SEO optimization' feature.

For high-traffic multi-site deployments, reverse proxy can also implement load balancing.This means that when there are multiple AnQiCMS instances (even if they manage different sites or are deployed solely to share the load), the reverse proxy can distribute incoming requests evenly or according to a strategy to different backend AnQiCMS instances, thereby avoiding overloading a single instance and improving the availability and responsiveness of the entire system.AnQiCMS is developed in Go language, featuring a 'high-performance architecture' and 'high concurrency characteristics', combined with reverse proxy load balancing, which can maximize its performance advantages.

Simplify domain name management and URL rewriting

AnQiCMS multi-site management feature allows users to customize content models and diverse content display according to business needs, which naturally involves flexible domain names and URL structures.Reverse proxy provides great convenience in this aspect. It can be based on different domain names (such assite1.com/site2.com）or URL path（such asexample.com/brand1//example.com/brand2/Route the request accurately to the corresponding AnQiCMS site, to achieve unified management of website addresses.

At the same time, the reverse proxy supports powerful URL rewriting features.This means we can easily implement SEO optimization strategies such as 'pseudo-static and 301 redirect management', even if the URL structure within AnQiCMS changes, it can also smoothly transition through the reverse proxy layer to ensure the website's search engine friendliness and avoid traffic loss due to URL changes.

Unified log and monitoring

Manage traffic across multiple sites through reverse proxy, which also brings convenience to log recording and system monitoring.All external requests will first pass through a reverse proxy, which means we can centrally collect and analyze the access logs of all sites at the reverse proxy layer.This is crucial for carrying out "traffic statistics and crawler monitoring", which can help us understand user behavior, crawling situations, and potential abnormal accesses more comprehensively, providing data support for content strategy and SEO optimization.

This centralized log management and monitoring system simplifies the complexity of operations, reduces the need for separate configuration of monitoring for each AnQiCMS instance, and improves the efficiency of fault diagnosis.

In summary, reverse proxy is not an optional choice in the multi-site deployment of AnQiCMS, but the foundation for building an efficient, secure, scalable, easy-to-manage, and SEO-friendly enterprise-level content management system.It not only optimizes the user access experience, but also provides multiple guarantees for the stable operation of AnQiCMS at the underlying architecture.

Frequently Asked Questions (FAQ)

Does reverse proxy affect the performance of AnQiCMS?

In most cases, a well-configured reverse proxy will not affect the performance of AnQiCMS, but will significantly improve overall performance.It relieves the burden of AnQiCMS itself by means of static resource caching, SSL offloading, request filtering, and possible load balancing, thereby accelerating the response speed.Of course, if the reverse proxy configuration is not properly set up or the server resources are insufficient, it may also introduce additional delays, therefore, choosing a high-performance reverse proxy software and optimizing the configuration is crucial.

Do I need to configure a separate reverse proxy for each AnQiCMS site?

It is not necessary. AnQiCMS itself has the ability to manage multiple sites, allowing you to run multiple independent websites within a single AnQiCMS program.Generally, you only need a reverse proxy service (such as Nginx or Apache), which will forward requests to a single backend service instance running AnQiCMS based on different domain names or URL path rules.Only when you need to deploy multiple AnQiCMS instances for extremely high availability or performance, the reverse proxy will distribute traffic to these different backend instances.

Does reverse proxy conflict with AnQiCMS built-in pseudo-static function?

The reverse proxy and the built-in pseudo-static feature of AnQiCMS work together rather than conflicting.The AnQiCMS pseudo-static feature is responsible for generating internal friendly URL structures, while the reverse proxy is responsible for correctly routing external requests' URLs (usually after pseudo-static processing) to the AnQiCMS service, and can also manage and optimize these URLs when displayed externally.The reverse proxy can even supplement the pseudo-static function of AnQiCMS, handling more complex URL rewrite rules or implementing more advanced SEO strategies, such as enforcing HTTPS, adding HSTS headers, etc.
