What are the roles and responsibilities of a Linux Administrator

It’s a well-known truth that Linux is one of the most basic operating systems, with low hosting costs and an open-source database. For hosting and other web application needs, the majority of users favor Linux servers.

But what distinguishes Linux from other operating systems is that in 2008, it was a $25 billion ecosystem. Linux has evolved to become a computing force since its birth in 1991, powering everything from the New York Stock Exchange to mobile phones, supercomputers, and consumer gadgets.

Linux is an open operating system, which means that it is developed cooperatively rather than being solely the responsibility of a single corporation. The Linux economy encourages companies to share research and development expenditures with their partners and rivals. Individuals and businesses have contributed to its growth, resulting in an efficient environment and software innovation.

System administration has become a must-have skill for any company that relies on a robust IT infrastructure. As a result, effective Linux administrators are in short supply. Each organization’s job profile may differ since the function may take on additional duties. A senior Linux administrator’s responsibilities include the following:

  1. He must be capable of managing all internet programs, such as DNS, RADIUS, Apache, MySQL, and PHP. One of the responsibilities is to take frequent backups of data, develop new storage methods, and perform periodic backups.
  2. He should be able to help and teach other server administrators in the firm as a senior Linux administrator.
  3. Another responsibility is to review and correct any error logs, as well as to provide better customer assistance for Webhosting, ISP, and LAN customers on troubleshooting escalated support issues.
  4. He must be able to communicate with his coworkers, vendors, and customers in a pleasant and professional way at all times.
  5. It is the responsibility of every Linux administrator to install the appropriate processes and security tools. He analyzes hardware needs and options with the Data Network Engineer and other personnel/departments and makes procurement recommendations.
  6. The Linux administrator’s job is to keep the server’s software up to date, including virus software and code upgrades.
  7. Ability to deal with Linux-friendly programs and resolve them when a server-related issue develops.

If you believe that you can fulfill these responsibilities, it is possible for you to go ahead and become a Linux administrator on your own.
