It is not very complicated, but each file to be rotated needs to be specified. Each file may also need different configuration options. Instead of editing this single file each time an application is added or updated on the system, we separate the configuration for each application to a specific file. The main configuration file includes all files in another directory.
Files in the directory may originate from different RPM packages. The owner of each package knows what needs to be rotated and how frequently. They provide a configuration file specific to their application and add it to logrotate.
It is also removed from logrotate. Other examples of this use case are scheduling with cron in the cron. By using separate files, the system administrator does not need to manage conflicting writes to a single file.
The Apache web server is an extensive program with many configuration options. Apache utilizes a conf. When I started with Apache, it was common to have a single server host multiple virtual sites. Each of those virtual hosts had its own configuration file. This approach allowed us to share the administration duties of the files as well as share the files on different systems during migration, recovery, and load balancing.
Today, I see more cases where the configuration is separated by function. The ssl. Other modules may also drop files into the conf. It is up to the web administrator to create or manage the production files. Free online course: Red Hat Enterprise Linux technical overview. As I suggested with web configuration files, another use of separate configuration files is to make centralized management of these files easier, and only distribute relevant components to each managed node.
The modules. These settings may only be needed on some systems, or may require hardware-specific settings. The settings can be organized by hardware, function, or a combination. Configuration management programs can push just the relevant files to specific managed hosts or generate the files on each host based on a template.
While dot-d directories have common use cases for assisting with organization and distribution, there are many different ways of handling the includes. For each application or utility, we need to determine how best to name our files. Some configurations only recognize files with a specific extension, such as. The man pages for the main configuration file, such as man logrotate. Still, I start by looking for an include statement in the configuration file.

Next, skip down to the After editing section and note the systemctl daemon-reload command used to update the systemd components after making changes to this file. Now that we have looked at the comments, let's break down the actual configuration that is present and look at the various bits of info that a user needs to note. You also see that it is an xfs filesystem. You may see any number of options here, such as ext3, ext4, fat file systems, etc.
The UUID remains persistently assigned to the filesystem. UUIDs are a great way to label filesystems, especially in smaller environments. However, they can lead to issues in larger environments where network-based drives are in use. Moving to the right, you see a pair of zero's. The next number to the right tells the system to run a filesystem check or fsck. The root filesystem should be set to 1 and any others you want to be checked assigned after that.
NOTE : These options must be listed in order if the configuration is to work correctly. There are other options for more advanced users that I do not have configured here therefore, there are no examples shown. However, there are some great resources on the web to explain these options.
The ones that I would check out are as follows:. Many casual users do not use this file. However, if you find yourself curious or in need of making changes, you are now better equipped to do so!
