As an experienced AnQiCMS website operation personnel, I know that a smooth system is the foundation for content creation and publication.AnQiCMS with its high efficiency and easy scalability, brings great convenience to our content operation work.However, during the system deployment process, there may occasionally be some minor setbacks, of which the most common and troublesome are the problems of 'port already in use' and 'insufficient database permissions'.Learn how to quickly identify and resolve them, which will ensure a smooth journey for your AnQiCMS.

Port occupation problem troubleshooting and resolution

When installing or starting AnQiCMS, if the system prompts "Port is already in use", this means that the port number (default 8001) assigned to AnQiCMS is being used by another program on the server.This is like you want to move into a room, only to find that someone is already living there.

To troubleshoot which program is occupying the port, you can open the terminal and uselsof -i:{端口号}Command. For example, to check port 8001, you just need to inputlsof -i:8001.The system will list the process ID (PID) and program name that is using the port.Once the occupant has been found, you can choose a solution based on the actual situation.kill -9 {PID}command to force terminate it. Please be sure to operate carefully and ensure you understand the impact of terminating the process.

For Windows operating system, you can view and end processes through Task Manager. PressWin键+Rto inputtaskmgrOpen Task Manager, or right-click on the taskbar and select "Task Manager.Switch to the "Details" or "Processes" tab, find the corresponding process that is using the port and end the task.Sometimes, a simple restart of the service or computer can also solve temporary port occupation problems.

Another method to resolve port occupation is to change an unused port for AnQiCMS. The configuration file of AnQiCMS (usuallyconfig.json) will contain aportField, you just need to edit the file, change the port number to a new, available port, such as 8002 or 8003.If you are deploying through Baota panel or 1Panel and tools, there will also be port configuration options when creating a Go project or Docker container. Make sure to fill in a different server port here, while the container port usually remains as the default 8001 for AnQiCMS.After modification, restart the AnQiCMS service, and the system will run normally.

Insufficient database permission troubleshooting and resolution

Insufficient database permissions are another common installation obstacle, which is usually manifested as AnQiCMS being unable to create a database, create tables, or write data.This is similar to you having an important file that needs to be saved in a safe, but the administrator of the safe has refused your access privileges.

In the AnQiCMS initialization installation interface, if it prompts that the database connection fails, cannot create the database, or cannot write data, first you need to check whether the username and password you entered for the database are correct.This is the most basic and easiest step to make a mistake.Ensure that this information is completely consistent with your database server configuration, including case sensitivity.

Solve this problem usually has two ways. The first is to use a database user with higher privileges to complete the installation. For example, in MySQL,rootUsers typically have all permissions, you can userootUsers and their passwords are installed. However, for security reasons, it is recommended to create a new database user specifically for AnQiCMS and grant it sufficient permissions.

The steps to create a new user and assign permissions are usually as follows: Log in to the database management tool (such as phpMyAdmin, Navicat, or through the command line). Create a new database user (for example,anqicms_userSet a strong password and grant the user access to a specific database (for example,anqicms_dbAll permissions, or at least the key permissions required for AnQiCMS to run. The specific commands may be similarGRANT ALL PRIVILEGES ON anqicms_db.* TO 'anqicms_user'@'localhost' IDENTIFIED BY '您的密码';(Please modify the database name, username, host, and password according to your actual situation). Refresh permissions: FLUSH PRIVILEGES;.

After completing the permission settings, go back to the AnQiCMS installation interface and configure it using the newly created database user and password. Usually, the installation can be completed successfully.

Summary

As a website operator, encountering technical problems is inevitable.When AnQiCMS installation encounters port occupation or database permission issues, stay calm, follow the steps above one by one, and usually it can be resolved smoothly.Clear thinking and a basic understanding of the system's operation mechanism are the key to ensuring the stable and efficient operation of the content platform.Wish your AnQiCMS site to operate successfully!

Common Questions (FAQ)

Q1: How can I troubleshoot if the website is still inaccessible after modifying the default port 8001 during the installation of AnQiCMS?A1：Firstly, please confirm that the port you have modified is not occupied by other programs, and you can follow the methods mentioned in the article (such as under Linux,lsofCheck the command or Windows Task Manager.Next, if you have used a reverse proxy (such as Nginx or Apache), make sure that the reverse proxy configuration has also been updated to point to the new port of AnQiCMS.proxy_passThe address should be consistent with the port where AnQiCMS is actually running.

Q2: I have created a separate database user for AnQiCMS, but during the installation, it still prompts insufficient permissions. How can I verify the permissions of this user?A2：You can try to connect to the database using the database user and password, through database management tools (such as MySQL Workbench, Navicat, or command line). After a successful connection, try to perform some basic operations, such asCREATE DATABASE test_db;orCREATE TABLE test_table (id INT);Observe whether an error occurs. If these operations fail, it means that your database user permissions are indeed insufficient, and you need to contact the database administrator to upgrade the corresponding permissions or reauthorize.

Q3: How do I deal with port occupation issues when installing AnQiCMS using Docker?A3: When deploying AnQiCMS with Docker, it is common to perform port mapping between the host machine and the container. If you are prompted that the host port is occupied, you just need to modifydocker runThe host port in the command or Docker Compose file can be used, for example,8001:8001to8002:8001.This means that the host's 8002 port is mapped to the container's 8001 port.If the problem is inside the container, this is usually not common unless you are running other services inside the container.
