Operation and maintenance engineers generally have directions such as system operation and maintenance, network operation and maintenance, operation and development, database operation and maintenance, and cloud operation and maintenance. Today, I mainly introduce some skills and textual research needed by system operation and maintenance engineers.

Essential skills of system operation and maintenance engineer

System operation and maintenance engineers should not only have the basic operating skills of Linux, but also know the skills of server hardware, dual-machine cluster, Windows, VMware, database and so on, in order to become qualified system operation and maintenance engineers.

It should be noted that the physical machines of enterprises all use dual-computer cluster, so we must master the skills of dual-computer cluster, including Linux dual-computer cluster, Windows dual-computer cluster, Oracle Rac database cluster, SQL Server database cluster and so on.
