How to fix 404 errors encountered when deploying a ThinkPHP 6 project on port 8088 via Nginx on Ubuntu?

Ubuntu system Nginx deploys ThinkPHP 6 project, 8088 port 404 error check

When deploying PHP projects using Nginx on Ubuntu, especially when listening for non-standard ports (such as 8088), you often encounter 404 errors. This article will analyze in detail the 404 problems encountered when deploying ThinkPHP 6 projects on port 8088 through Nginx on Ubuntu and provide solutions.

Problem description

On Ubuntu systems, using Nginx to deploy ThinkPHP 6 project to port 8088, accessing any interface or files under public directory will return a 404 error. The Alibaba Cloud Security Group has released port 8088.

Nginx configuration file

Configuration file under conf.d (xxx.conf):

 server {
    listen 8088;
    server_name your server IP address; # Please replace it with your server IP

    root /path/to/your/project/public; # Please replace it with your project's public directory path index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php?$args; # simplify try_files directive}

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock; # Please check whether the php-fpm socket path is correct fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; # Use the standard parameter name include fastcgi_params;
    }
}

nginx.conf file (some key configurations):

 user www-data;
worker_processes auto;
# ... other configurations ...
include /etc/nginx/conf.d/*.conf;
# ... other configurations ...

Solution

1. Configuration file syntax check: Use nginx -t xxx.conf to check configuration file syntax errors. If there is any error, modify and re-run the command. Then execute systemctl reload nginx or service nginx reload to restart the Nginx service.

2. Local testing: Use curl 127.0.0.1:8088 on the server to test whether it is accessible. If you can access it, it means that the Nginx configuration is basically correct, and the problem may be in the external network configuration of the server or the firewall.

3. Network configuration and firewall:

   • Firewall: Confirm whether Ubuntu firewall (such as UFW) allows access to port 8088. You can use sudo ufw allow 8088 to allow access, and then sudo ufw status to view the status.
   • Alibaba Cloud Security Group: Check the Alibaba Cloud Security Group rules carefully again to ensure that the entry direction rules for port 8088 are correctly configured and allow your client IP address to access.

4. php-fpm socket path: Ensure that the /var/run/php/php7.4-fpm.sock path is correct and is consistent with the configuration of php-fpm. Check whether the php-fpm service is running normally.

5. Permissions issue: Check whether the Nginx user (www-data) has read execution permissions for the project directory and its files.

6. ThinkPHP 6 routing configuration: Check whether the routing configuration of the ThinkPHP 6 project is correct to ensure that the request can be processed correctly.

7. Log check: Check Nginx error log /var/log/nginx/error.log nginx/error.log to see if there is more detailed error information.

If the above steps still fail to resolve the problem, please provide the following information for further troubleshooting:

• Server operating system version
• Nginx version
• PHP version
• php-fpm configuration
• ThinkPHP version 6
• Complete Nginx error log content

By systematically examining each of the above aspects, you should be able to find and resolve the root cause of the 404 error.
