Linux Certifications Training
Linux is an operating system capable of running a variety of technologies, from desktop computers to mobile phones and video game consoles. Linux is an open-source system; meaning software developers may use, modify and redistribute its source code freely--making it a popular choice among IT professionals around the globe. It is also one of the most powerful systems available: According to Top500.org, as of June 2010, Linux ran the 10 fastest supercomputers in the world.
Linux skills are in demand, according to PCWorld. Find out how a Red Hat certification can demonstrate expertise in Linux.
The flexibility of the Linux operating system makes it a valuable tool for businesses and IT professionals, but learning how to best use and manipulate it requires some training. This is why Linux certifications are such valuable IT credentials for entry-level and seasoned professionals alike.
The value of Linux certifications
The flexibility of Linux makes it appealing for IT professionals and organizations over less customizable systems like Windows, but at the same time, this malleability gives Linux a reputation for being user-unfriendly. Because of this, Linux-certified professionals may earn more than their lesser-trained peers. Global Knowledge's 2011 IT Skills and Salary Report indicates that Linux-certified professionals earned median salaries ranging from $78,330 to $92,322, depending on the certification earned, which was notably more than the $72,200 that the U.S. Bureau of Labor Statistics reported as the median annual salary for all network and computer systems administrators just a year earlier.
Because Linux is an open-source operating system, many Linux certifications are considered vendor-neutral. The following are among the most common Linux certifications available.
Linux Professional Institute (LPI) certifications
Linux Professional Institute Certification Level 1 (LPIC-1): The LPIC-1 certification is designed for junior-level IT professionals, certifying that they can work at the command line, perform basic maintenance, and install and configure a network-connected workstation.
Linux Professional Institute Certification Level 2 (LPIC-2): The LPIC-2 is an advanced-level certification that builds upon the skills established through the LPIC-1 curriculum. LPIC-2 certified professionals must be able to administer a small to medium-sized site using Microsoft and Linux servers while being knowledgeable enough about Linux systems to advise upper management.
Linux Professional Institute Certification Level 3 (LPIC-3): The most advanced credential in the LPI certification program, this senior-level certification builds upon the LPIC-1 and LPIC-2 curricula.
CompTIA Linux+: The CompTIA Linux+ certification is an LPI-powered credential certifying that junior-level IT professionals--those with six months to a year of practical experience--can install and use Linux operating systems.
Red Hat certifications
The creator of Red Hat Linux, a popular enterprise operating platform, Red Hat offers a number of Linux certifications. The following represent basic Red Hat credentials; IT professionals can pursue a number of additional, specialized certifications.
Red Hat Certified System Administrator (RHCSA): The RHCSA is an entry-level credential that certifies one can install and configure a Red Hat system and attach it to a live network.
Red Hat Certified Engineer (RHCE): The RHCE certification is for mid-level to advanced IT professionals who have already earned the RHCSA. The RHCE credential certifies that one can tackle more advanced functions, such as security or the installation of common enterprise networking (IP) services.
Red Hard Certified Architect (RHCA): This Red Hat-titled "capstone certificate" is the most advanced Red Hat credential available, building upon the RHCE curriculum with an "enterprise focus."
