Where is Service Unit File in Linux?
In this section, we’ll uncover the various directories and paths where service unit files can be found in a Linux system. Let’s dive in.
/lib/systemd/system Directory
One of the primary locations for service unit files in Linux is the /lib/systemd/system directory. Here, you’ll discover essential system service files that play a crucial role in the overall system functionality. These files are typically used by the systemd init system, which is prevalent in modern Linux distributions.
/etc/systemd/system Directory
For user-specific service configurations and overrides, you’ll want to explore the /etc/systemd/system directory. This directory allows you to customize service unit files according to your specific needs, making it a valuable resource for system administrators.
/usr/lib/systemd/system Directory
The /usr/lib/systemd/system directory is another location where service unit files can reside. It is commonly used for third-party or additional service files that are not part of the core system but are still essential for certain applications.
Custom Locations
In some cases, service unit files might be stored in custom locations defined by specific applications or services. These locations can vary widely depending on the software you’re using. Always refer to the documentation or configuration files of the respective service for precise details.
