1. CompTIA Linxu+

CompTIA Linux+ is a Linux certification sponsored by LPI (Linux Professional Institute,Linux Professional Committee) that provides training worldwide. The Linux-related knowledge it provides can be used to engage in a large number of Linux-related professional work, such as Linux administrators, senior network administrators, system administrators, Linux database administrators and Web administrators. If anyone wants to install and maintain the Linux operating system, the course will help him meet the certification requirements and prepare for passing the exam by providing a broader understanding of the Linux system. The main purpose of LPI's CompTIA Linux+ certification is to provide certificate holders with solid knowledge of software installation, operation, management, and equipment troubleshooting. We can pay a certain amount of money, time and effort to complete CompTIA Linux+, and obtain three industry-recognized certificates: LPI LPIC-1 and SUSE Certified Linux Administrator (CLA) certificates.
