How to solve the problem that php5 is not listening on port 9000

The operating environment of this tutorial: windows10 system, php8.1.3 version, DELL G3 computer.

PHP is a widely used server-side scripting language for developing dynamic websites and applications. When using PHP to run a website, you may encounter the problem that PHP5 does not listen to port 9000. This article will introduce the solution to this problem and help you quickly solve the problem that PHP5 cannot listen to port 9000.

First, let us understand why PHP5 cannot listen to port 9000. By default, PHP-FPM (FastCGI Process Manager) uses sockets instead of ports for communication on Linux systems. This means that by default, PHP-FPM will listen on socket files instead of port numbers. So if you try to run PHP-FPM on port 9000, you may run into problems.

To solve this problem, you can take the following steps:

1. Check the PHP-FPM configuration file: Go to the directory where your PHP-FPM configuration file is located. On most Linux systems, the configuration file is located at /etc/php5/fpm Under contents. Open the configuration file, usually named php-fpm.conf or php-fpm.ini. Make sure the following configuration options are set to the correct values:

listen=127.0.0.1:9000

This will cause PHP-FPM to listen on port 9000 on localhost for incoming connection requests. If the value for this option is incorrect, change it to 127.0.0.1:9000 and save the file.

2. Restart the PHP-FPM service: In order for the changes to take effect, you need to restart the PHP-FPM service. On most Linux systems, the service can be restarted using the following command:

sudoservicephp5-fpmrestart

This will restart PHP-FPM and start listening on port 9000 for incoming connection requests.

3. Turn off the firewall or configure port forwarding: If the firewall is enabled on your system and port 9000 is blocked, then PHP-FPM will not be able to listen for connection requests on that port. You can choose to turn off the firewall or configure port forwarding to allow traffic through port 9000.

For most Linux systems, you can turn off the firewall using the following command:

sudoufwdisable

Please note that turning off the firewall may cause potential risks to the security of the system. If you decide to turn off your firewall, make sure your system is protected by other security measures, such as using network security devices and regularly updating your operating system.

4. Check whether other processes occupy port 9000: If the above steps fail, you can check whether other processes occupy port 9000. You can check the usage of port 9000 using the following command:

sudonetstat-tuln|grep9000

If the output shows that another process is using port 9000, you can do this by killing the process or configuring PHP-FPM to run on a different free port. to solve this problem.

To sum up, to solve the problem that PHP5 cannot listen to port 9000, you need to check the PHP-FPM configuration file, restart the PHP-FPM service, turn off the firewall or configure port forwarding, and check whether other processes occupy port 9000. With the above steps, you should be able to successfully resolve the issue and have PHP-FPM listening on port 9000 for incoming connection requests. Hope this article is helpful to you!
