What is the mapping rule for server port and container port when installing Panel with CMS?

As a website operator who deeply understands the operation and maintenance of security CMS, I know that understanding the basic infrastructure is crucial when deploying and managing the system.Wherein, the port mapping rule between server ports and container ports in the Docker environment is a common point of confusion for many users when they first encounter it.Today, I will analyze the key configuration when installing APanel CMS from the perspective of actual operation in detail.

The default port of AnQi CMS in Docker container

Firstly, we need to clarify the operation mechanism of AnQi CMS within the Docker container. According to the design and deployment specifications of AnQi CMS, regardless of which host machine (i.e., your physical or virtual server) you run Docker on, the AnQi CMS application always listens by default inside the container.8001Port.This 8001 port is the 'internal address' used by the security CMS application in an isolated Docker environment, which is the basis for providing services.All access requests to the AnQi CMS must eventually be routed to port 8001 inside this container.

1Panel installation's port mapping mechanism

When you create a security CMS container by using Docker on the 1Panel management panel, 1Panel provides a user-friendly interface to configure port mapping.The fundamental purpose of port mapping is to establish a connection between a certain port on the host machine and the 8001 port that the Docker container's internal CMS is listening on.In the "Create Container" or "Edit Container

Here, the 'Container Port' is fixed to be filled in as8001，因为它代表着安全CMS在Docker容器内部实际运行的端口。While the 'Server Port' needs to be set according to your actual situation, it refers to the port exposed by your host machine to the outside.For example, if you are installing AQ CMS for the first time and the 8001 port on the host machine is not occupied, you can also set the 'server port' to 8001.宿主机8001:容器8001The mapping relationship.This means that any traffic sent to the host port 8001 will be automatically forwarded by the Docker engine to the 8001 port inside the AnQi CMS container.

Deployment port strategy for multiple sites

In the operation of actual websites, many users may need to deploy multiple security CMS instances on the same server to manage different brands or projects.In this multi-instance deployment scenario, understanding the flexibility of port mapping is particularly crucial.8001auto. To ensure that each instance can run independently and without port conflicts, you must assign a unique port for each security CMS container inAn allocated different, unused server port on the host machine.

For example, the first security CMS instance can be configured as宿主机8001:容器8001If you want to install a second CMS instance, when creating its container, the 'container port' is still 8001, but the 'server port' needs to be selected as another unoccupied port, such as 8002, forming宿主机8002:容器8001The mapping. Similarly, the third instance can be宿主机8003:容器8001Through this method, although all security CMS are using 8001 within the container, they provide services to the outside world through unique ports on the host machine.

Reverse proxy and external access

After completing port mapping, the next step is usually to configure reverse proxy for your website domain.Reverse proxy service (such as the Nginx reverse proxy function integrated by 1Panel) will listen to standard HTTP (port 80) or HTTPS (port 443) requests.It forwards these requests to the host port of the corresponding security CMS instance based on the domain name accessed by the user.

For example, if your domain namewww.example.comThe corresponding CMS instance is mapped to the host port 8001, then you need to configure in 1Panelwww.example.comSet up a reverse proxy and point its proxy address to127.0.0.1:8001. When the user accesses through the browserwww.example.comWhen, the request first arrives at the reverse proxy, the reverse proxy then forwards it internally to the host port 8001, and then it is forwarded to the 8001 port inside the Ant CMS container by Docker.This mechanism not only hides the backend port details, improves security, but also facilitates SSL certificate management and unified access to multiple sites.

Summary

In short, when installing AQCMS via Docker on 1Panel, it is crucial to understand the core port mapping rules, which associate the internal container port (fixed at 8001) with the external host port.Whether it is a single instance or multi-instance deployment, the container internal port remains unchanged, while the host port needs to be configured flexibly to avoid conflicts.With the powerful reverse proxy function, your CMS site can provide clear and stable domain services.The correct port mapping is a crucial step for the stable operation and efficient management of the CMS, ensuring that content can smoothly reach your target users.

Common Questions and Answers (FAQ)

Q1: Why is the internal port of the APT CMS container always 8001, and I only need to change the server port?

The Anqi CMS application is set to listen on port 8001 in an isolated Docker container environment during development, which is its 'default address' for providing services inside the container.You can understand it as an internal agreement.Server port, also known as host port, is the port your server exposes to the outside.The Docker port mapping feature allows you to map any unused port on the host machine to the internal port 8001 of the container.The advantage of doing so is that even if the application port inside the container is fixed, you can achieve multi-instance deployment by changing the host port, avoiding port conflicts, and it will not affect the operation logic inside the CMS container.

Q2: Can you access the Safe CMS directly through the server IP address and port without configuring a reverse proxy?

Theoretically, it is possible. After correctly configuring the mapping of server port and container port, you can throughhttp://服务器IP:服务器端口[for example]http://192.168.1.100:8001）Directly access the security CMS.However, in the actual production environment, we strongly recommend configuring reverse proxy and accessing through domain names.This can not only enhance the professional image of the website and facilitate user memorization, but is also crucial for search engine optimization (SEO).In addition, reverse proxy can provide additional functions such as SSL certificate management, traffic distribution, and security protection, further enhancing the robustness and security of the website.
