In depth knowledge of setting up Linux systems, developing servers and working with users to ensure that the system works reliably and quickly and answer questions related to setup and installation. Design the architecture of the system, including back-end databases and scripts for specific applications and use cases.
Ability to perform routine system maintenance and resolve server-side issues as they arise by reviewing error logs and reported errors and seek out solutions. Need to work directly with the system’s source code to make necessary changes to ensure reliable performance and then deploy those changes throughout the system.
Knowledge to conduct system backups based on company or industry standards on weekly, daily or more frequently depending on system space and business needs. This improves system recovery after a crash or other outage and supports data integrity by ensuring that there is never a massive loss of vital information.
Knowledge to monitor system performance to prevent slowdowns and crashes by examining daily traffic logs and reports or receive direct reports from end users. Observe potential issues or recurring problems within the system so as to develop and deploy solutions so that the system remains usable for all personnel.
Capability in providing technical support and guidance to users and other administrators. In many cases, the Linux administrator works closely with other developers to answer technical questions or resolve issues with server-side performance. They may also support users by assisting with installation and maintenance of Linux-based programs and help debug these applications so that they work with existing servers.
Intended to maintain system security by actively identifying faults and vulnerable areas within the system’s architecture. Need to develop protection from any sort of vulnerabilities particularly while developing system-wide changes.
Knowledge in programming and scripting in SHELL/Perl/Python. For process automation, effort reduction and value addition.
Linux administrators need to be highly analytical and able to examine error logs, system performance data, and user information to ensure a high level of usability and reliability
