Doesn't etc/logrotate.d/tomcat-run.daily take effect? Manual trigger?
If you're running a Talend Data Stewardship application server and want to rotate the catalina.out log file, you might have come across the article on DZone that explains how to configure logrotate for Tomcat.
However, you might have encountered an issue where the configuration in /etc/logrotate.d/tomcat-run.daily does not seem to take effect. In this article, we will explore why this might be the case and how to manually trigger log rotation.
Understanding logrotate
logrotate is a utility for managing log files created by system processes. It allows you to specify how log files should be rotated, compressed, and removed. The configuration for logrotate is typically stored in the /etc/logrotate.d directory, with each file representing a different service or application.
In the case of Talend Data Stewardship, the configuration file for rotating the catalina.out log file is typically located at /etc/logrotate.d/tomcat-run.daily.
Why doesn't the configuration take effect?
There are a few reasons why the configuration in /etc/logrotate.d/tomcat-run.daily might not take effect:
The configuration file is not valid. Check the syntax of the file to ensure that it is correct.
The log file is not owned by the user specified in the configuration. Make sure that the user specified in the configuration has ownership of the log file.
The log file is not located in the directory specified in the configuration. Make sure that the log file is located in the correct directory.
The log file is being written to by another process. If another process is writing to the log file,
logrotatemight not be able to rotate it.
Manually triggering log rotation
If the configuration in /etc/logrotate.d/tomcat-run.daily is not taking effect, you can manually trigger log rotation using the following command:
sudo logrotate -f /etc/logrotate.d/tomcat-run.daily
This will force logrotate to rotate the catalina.out log file, even if the configuration is not taking effect.
In this article, we have explored why the configuration in /etc/logrotate.d/tomcat-run.daily might not take effect and how to manually trigger log rotation. By understanding how logrotate works and how to troubleshoot issues with log rotation, you can ensure that your Talend Data Stewardship application server is running smoothly.
