A Linux system administrator is responsible for the standard day-to-day administration of Linux servers. This would include, but not be limited to, deployment of a standard LAMP (Linux, Apache, MySQL and PHP) web server configuration, including installing all standard plugins, SSL and configuration. A Linux system administrator should also be familiar with at least two different Linux distributions. Ideally, one of the Linux distributions should be Redhat Enterprise Linux, the most common distribution used in the corporate world. The second distribution should be one of the Debian based distributions (such as Debian and Ubuntu), since most cloud service providers use some form of Debian for their servers. A typical applicant should have at least three years of experience in day-to-day administration of Linux servers.
