Duties and Responsibilities of the Linux Administrator

Linux administrators are back-end IT specialists who install, configure and manage Linux operating systems in a variety of organizations. This role includes server-side operations and troubleshooting activities that support business-critical development and activities. Linux administrators also configure user access and monitor system stability and security through deployment and daily use.

This functionality requires a great deal of familiarity with Linux systems and servers and can involve a high level of risk assessment and user support. Since Linux is an open source operating system, administrators often communicate and also collaborate with other developers to develop and implement system improvements.

Duties and Responsibilities of the Linux Administrator

While the specific duties of a Linux administrator may vary based on your business and industry, the overall responsibilities of this role are relatively consistent. Based on the lists we've reviewed, these tasks include:

Install and configure Linux systems

The primary responsibility of a Linux administrator is to install and configure Linux systems and servers, often for organization-wide deployment. They develop servers and work with individual users to ensure that the system works reliably and quickly, and answer questions related to configuration and installation. In this role, Linux administrators also configure the system architecture, including databases and backend scripts for specific applications and use cases.

Perform system maintenance

Linux administrators also perform routine system maintenance and fix server-side issues as they arise. This aspect of the feature requires the Linux administrator to review the error logs and reported errors to find solutions. Linux administrators often have to work directly with the system's source code to make the necessary changes to ensure reliable performance and then implement those changes throughout the system.

Create system backup

Linux administrators also perform system backups according to company or industry standards. They can perform these backups weekly, daily, or more frequently, depending on system space and business needs. This improves system recovery after a crash or other outage and supports data integrity by ensuring that a massive loss of vital information never occurs.

Monitor system performance

In addition to maintaining Linux systems and servers, Linux administrators also monitor system performance to prevent slowdowns and freezes. They can review daily traffic reports and logs or receive direct reports from end users. If the Linux administrator detects potential problems or recurring problems within the system, he develops and implements solutions so that all personnel can use the system.

Provide technical assistance and guidance.

Linux administrators provide technical assistance and guidance to users and other administrators. In many cases, the Linux administrator works closely with other developers to answer technical questions or troubleshoot server-side performance issues. They can also help users by assisting with the installation and maintenance of Linux-based programs, and by helping to debug these applications to work with existing servers.

Maintain system security

Finally, Linux administrators maintain system security by actively identifying flaws and vulnerable areas within the system architecture. This part of the job requires a thorough understanding of viruses and other sources of system vulnerabilities, and requires the Linux administrator to proactively develop protections, particularly when implementing system-wide changes that can open up new vulnerabilities.
