When AnQiCMS default port is occupied, how to find and terminate the conflicting process through PID?

HelloAs an experienced CMS website operation personnel, I completely understand the distress encountered when technical problems arise during the operation process, especially when it affects the normal operation of the website.Port occupancy is one of the common but relatively easy problems to solve.When the default running port of AnQi CMS is occupied by other programs, the system will fail to start normally.Below, I will explain in detail how to locate and terminate these conflicting processes to ensure your safe CMS website goes live smoothly.

AnQiCMS port occupation: locate and resolve the conflicting process

AnQiCMS (AnQiCMS) is an efficient content management system that listens on a specific port (default 8001) to provide services when it starts.However, in some cases, such as when other applications are running on the server, or when the previous security CMS was not properly closed, leaving behind residual processes, this default port may be occupied.When this situation occurs, Anqi CMS will fail to start normally, usually accompanied by port binding error information in the log.

To solve this problem, we need to find out which process is using the port required by AnQi CMS and then terminate it.This process may vary in different operating system environments, but the core idea is the same: identify the process ID (PID) and then force it to close.

Locate and terminate processes in Linux or macOS environments

On Linux or macOS servers, we can use command line tools to quickly diagnose and resolve port occupation issues.First, you need to log in to your server via SSH.

The first step to locate the process occupying the port is to uselsofcommand.lsof(list open files) is a very useful tool that can list all open files in the system, including network connections.We can filter out the process occupying the specified port.

lsof -i:8001

After executing this command, the system will return a list containing all processes that are using port 8001.The output usually displays the process command (COMMAND), process ID (PID), user (USER), and network protocol and address.

COMMAND   PID  USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
anqicms  7621 root    3u  IPv4  66205      0t0  TCP *:8001 (LISTEN)

In this example, we can seeanqicmsThe process ID corresponding to this command is7621. It is listening on port 8001. If the displayed COMMAND is notanqicms, it means that another program is occupying the port.

Once you have determined the PID of the conflicting process, the next step is to terminate it. Usekillthe command can send a signal to the process, where-9The parameter indicates sending the SIGKILL signal, which is a forced termination signal that can immediately kill the process without giving it a chance to clean up.Be sure to use with caution, make sure you really want to terminate the process.

kill -9 7621

to7621Replace with the actual process ID you find. After execution, the process will be terminated, and the port will be released accordingly.

Locate and terminate the process in the Windows environment.

For users testing or deploying an enterprise CMS on the Windows operating system, locating and terminating conflicting processes is usually done through Task Manager.

First, you need to open the Task Manager. The quickest way is to pressWinkey +R, and enter in the 'Run' dialog box.taskmgrPress Enter or right-click on the taskbar to select Task Manager.

After opening Task Manager, you may see different views.If you see the concise view, please click the "Details" at the lower left to switch to the detailed view.In the detailed view, look for the 'Process' or 'Details' tab.

In the "Details" tab, you will see all the processes currently running on the system. Since Windows Task Manager does not have the direct function of filtering processes by port, you may need to manually search.anqicms.exe(If you have already started the Anqicms) or other suspicious process. If you are not sure which process it is, you can try to start Anqicms first, and if there is an error, it is likely thatanqicms.exeThe previous instance did not exit completely. Findanqicms.exeAfter that, select it and click the 'End Task' button at the lower right corner. The system will prompt you to confirm, and after confirmation, the process will be terminated.

Ifanqicms.exeThe process is not displayed, but you still suspect that the port is occupied, or you suspect that it is an unknown program, you may need to use some third-party network tools to check the port usage, or restart your Windows system to clear all processes.

Restart AnQi CMS

After successfully terminating the conflicting process and releasing the port, you should try to restart the Anqic CMS.If port occupation is the only issue, Anqi CMS should be able to start smoothly and begin to provide normal services.你的域名/system/) to verify if it is running normally.

Resolving port occupation issues is an important step to ensure the stable operation of the CMS. By familiarizing yourself with the above steps, you can effectively handle such common problems and ensure the continuous online operation of the website.

Frequently Asked Questions (FAQ)

1. How can I install and run multiple safe CMS instances on the same server to avoid port conflicts?

Run multiple safe CMS instances on the same server, each instance needs to listen on a different port.The default port of Anqi CMS is 8001.config.jsonFile, containing theportChange the parameter to a different unused port (e.g., 8002, 8003, etc.).In addition, if you are using a reverse proxy (such as Nginx or Apache) to access these instances, you also need to configure different domains or subdirectories for each instance, and point them to their corresponding custom ports.

2. Why did the AnQi CMS still fail to start after I terminated the process, and it still reported port occupation?

If the port is still reported occupied after the process is terminated, there may be several cases.First, make sure you are terminating the correct process.Sometimes there may be multiple processes with the same name or similar in the system.In some extreme cases, the operating system may need some time to fully release the port.You can wait a few minutes and then try to start AnQi CMS again.If the problem persists, it may be necessary to consider restarting the server to ensure that all remaining system resources are cleaned up.

3. I waslsofnot seeing the port occupied in the outputanqicmsIs it another program I know, can I kill it directly?

If you find that the port being occupied is a program you recognize, but is unrelated to AnQi CMS, and you are sure that the program does not currently provide critical services or can be temporarily interrupted, then you can use the above method.kill -9 PIDCommand terminates it.But before you perform this operation, you must understand the impact of terminating the program.If it is an uncertain program, it is recommended to conduct an investigation first, or consider configuring AnQi CMS to another available port to avoid unnecessary interference with existing services.
