Enabling PHP Slow Log in RunCloud Nginx Server

 

Introduction

Monitoring and identifying slow PHP requests is crucial for optimizing the performance of your web applications. RunCloud, a popular server management panel, offers a straightforward way to enable PHP slow logs. In this tutorial, we will guide you through the process of configuring slow logs for individual web applications on a RunCloud Nginx server. By following these steps, you will be able to track and analyze slow requests, allowing you to take necessary actions for performance improvement.

Prerequisites:

Before we begin, ensure that you have the following:

• Access to a RunCloud Nginx server.
• Basic knowledge of Linux terminal commands.

Step 1: Locate Web Application Configuration Files:

To enable slow logs for your individual web applications, we need to locate the respective configuration files.

Connect to your server via SSH or any preferred method.

Navigate to the /etc/php-extra directory:

cd /etc/php-extra

Here, you will find configuration files for your web applications.

Step 2: Add Slow Log Configuration:

To enable slow logs, we need to modify the web application configuration file.

Identify the configuration file for the web application you wish to enable slow logs for.

Open the desired configuration file using a text editor.

nano your_webapp.conf

Replace your_webapp.conf with the actual name of the configuration file.

Scroll to the end of the file and add the following lines:

slowlog = /home/runcloud/logs/fpm/slow.log
request_slowlog_timeout = 3s

Note: Modify the path /home/runcloud/logs/fpm/slow.log if necessary, depending on the owner and location of your web application.

Save the changes and exit the text editor.

Step 3: Restart PHP Service:

Once the slow log configuration is added, restart the PHP service for the changes to take effect.

Run the appropriate command to restart the PHP service based on the PHP version you are using. For example, if using PHP 8.1, execute:

service php81rc-fpm restart

Replace php81rc-fpm with the corresponding PHP service name for your setup.

Wait for the service to restart. This ensures that the slow log configuration is applied.

Conclusion

By following these steps, you have successfully enabled PHP slow logs for your web applications on a RunCloud Nginx server. Monitoring slow requests allows you to identify performance bottlenecks and optimize your applications accordingly. Analyzing slow logs helps in improving overall response times and enhancing user experience. Remember to adjust the file paths and commands according to your specific server configuration.
