php fpm change port

PHP FPM is a fast and efficient PHP interpreter that can communicate between web servers and PHP code. By default, PHP FPM uses port 9000 to communicate with the web server. But sometimes, we need to change the port to suit our environment or other needs. This article will explain how to change the PHP FPM port.

The following are the steps to change the PHP FPM port:

1. Open the configuration file of php-fpm

First, we need to find the configuration of php-fpm document. In Ubuntu, this file is usually located at /etc/php/*/fpm/pool.d/www.conf. For other Linux distributions, the file may be located in a different location. Open the file.

2. Find the listen directive

In this configuration file, we need to find the listen directive. This directive is used to specify on which port PHP FPM should listen. By default, the value of this directive is:

listen = 127.0.0.1:9000

3. Change the port number

To change the port number, we Just change the port number in the directive. For example, if we wish to change the port number to 8000, we should change the directive to:

listen = 127.0.0.1:8000

4. Restart PHP FPM

After completing the changes, we need to restart PHP FPM for the changes to take effect. In Ubuntu, we can use the following command to restart the service:

sudo systemctl restart php*-fpm

Please note that I have used the wildcard character (*) here instead of the PHP version number . You need to use the actual version number or codename.

5. Verify whether the changes have taken effect

After completing the above steps, we need to verify whether the changes have taken effect. There are several ways to do this.

a. Check the system log

We can check the system log to see if there are any records related to the change of the PHP FPM port number. For example, in Ubuntu, we can list the system log using the following command:

journalctl -u php*-fpm

If there is a record about the port number change, the change has been successful.

b. View the listening port

Another method is to view the port that PHP FPM is currently listening to. We can use the following command to list all active network ports and their related information:

sudo netstat -tlnp

In the output, we should be able to see that PHP FPM is listening to the configuration new port number.

Summary

Changing the PHP FPM port number is not complicated. You only need to change the listen directive in the configuration file and restart the service. Remember to verify your changes to make sure they have taken effect.
