What our customers are saying


At a Glance: Linux System Administration

Initially released in 1991 by Linus Torvalds while he was attending the University of Helsinki, Linux has grown into a widely popular open-source operating system. Whether you’re looking to launch a new web server, build a mobile app from the ground up, or maintain your mainframe computer, a Linux system administrator can help get your open-source project off the ground.
A Linux system administrator can help you install, configure, and run the Linux operating system on your servers and computer networks. They can perform routine server maintenance tasks, such as installing regular updates, debugging system errors, running security scans, and creating backups. Linux is the “L” in the popular LAMP stack—a server-side solution that also consists of an Apache server, MySQL, and the PHP programming language. Whether your servers are running on the Red Hat Enterprise Linux or SUSE Linux Enterprise Server distributions, or your computers are powered by Debian or Ubuntu, Linux system administrators on Upwork can install, run, and maintain your open-source servers and networks.
