As an experienced security CMS website operation person, I know that every detail may affect user experience and operational efficiency when deploying and maintaining the website.For the port occupation issues that may occur when installing AnQiCMS using Docker on the Baota panel, I will give you a detailed explanation of the solution.

Solve the port occupation problem when installing AnQiCMS with Docker on Baota

Deploying Auto CMS to the Baota panel Docker environment, we pursue its high efficiency and convenience.An auto CMS as a lightweight CMS developed based on the Go language can provide an isolated and portable environment when running in a Docker container.However, during the installation process, especially when managing multiple applications on the same server, you may encounter situations where ports are occupied, which will prevent the application from starting normally.This article will discuss in detail how to identify and resolve such port conflicts to ensure the smooth operation of the security CMS.

Understand port occupation

In the Linux system, each network service or application needs to communicate with the outside world through a specific 'port'.When you try to start an application (such as an AQ CMS Docker container) and map it to a port on the host, if the port is already being used by another process, a port conflict will occur.The Docker application of AnQi CMS listens on port 8001 by default inside the container.Therefore, when you install multiple security CMS instances on the same server, or when other services (such as other web applications, database services, etc.) have already occupied port 8001 on the host machine, you need to adjust the port.

Identify the occupied port

When the Docker application of AnQi CMS fails to start successfully and prompts a port occupation error, you need to confirm which process is occupying the target port. In the Linux environment, you can uselsofThis is a powerful tool for diagnosing network connections and inter-process associations, command to complete this check.

For example, if you suspect that port 8001 is occupied, you can execute the following command on the server terminal:lsof -i:8001

This command lists all processes using port 8001, including the process ID (PID), user, and command.Through this information, you can determine which program is using the port.If the command produces no output, it means that the port is currently not occupied.This helps you eliminate the possibility that the port itself is occupied, and instead check for other configuration issues.

Resolve port occupation issue

Once the process occupying the port is identified, you have several ways to resolve port conflicts:

Firstly, you can chooseTerminate the occupying process.lsof命令显示占用端口的是一个不重要或可以暂时停止的进程（例如之前失败的安装残余进程），您可以找到对应进程的PID，然后使用Englishkill -9Command forces the termination of the process. For example, iflsof -i:8001the output shows that the PID 7621 process is using the port, you can execute:kill -9 7621Please use with cautionkill -9Command, as this will force the termination of the process, which may result in data loss or system instability, unless you are exactly sure about the function and impact of the process.

A more recommended and safer solution isAllocate a new port for AnQi CMS.When you install anqicms through the Baota panel Docker application store, the system will provide a clear 'port' configuration item.In the Docker installation interface, after filling in the application name of the Safe CMS, you will see an option for configuring the port.Please note that the default port used by the AnQi CMS inside the Docker container is 8001, and this 'container port' usually does not need to be modified.You need to change is the 'server port', which is the port that the Docker container maps to the host machine.If the 8001 port on the host is already in use, you can change it to another unused port, such as 8002, 8003, or even 8080, 9000, and so on.Each time a new security CMS Docker application instance is installed, a different, unoccupied host port should be allocated for it.After modifying the completion port, click Confirm to proceed with the installation.

Adjust the reverse proxy site configuration

After the Aanqi CMS Docker application is successfully installed and mapped to a new server port, you still need to update the reverse proxy settings in the Baota panel to ensure that your domain name can correctly access the Aanqi CMS service.

In the "Website" management interface of the Baota panel, find the reverse proxy site you created for AnQi CMS.Click on the 'Settings' to enter the configuration page, then select the 'Reverse Proxy' tab.http://127.0.0.1:8001Modify to the new server port. For example, if you mapped the safe CMS to the host machine's port 8002 during Docker installation, then the proxy address should be modified tohttp://127.0.0.1:8002.

After saving the changes, your website domain will be pointed to the correct secure CMS Docker application instance through the updated reverse proxy rules, thereby resolving the access issues caused by port conflicts.

Summary

Resolve the port occupation problem when installing APT CMS via Docker, the key is to accurately identify conflicts and adopt appropriate strategies.In most cases, it can be easily solved by assigning a different host port when installing the CMS Docker application and adjusting the reverse proxy settings in the Baota panel accordingly.This not only ensures the stable operation of your content management system, but also leaves flexibility for deploying more applications on the same server.
