This format is not available in this course
About course
The average person has no idea how much IT has to do with databases. But the system administrator understands how many processes generally depend on databases, and knows how to manage them.
We will teach you how to administer popular databases.
What do you need to take the course?
You need to understand the following topics: text editors, user and group management, file and directory permissions management, Linux process management.
Iptables, troubleshooting for network connections, package managers, getting information about the versions of installed programs and available packages for installation in the repositories, a general understanding of the work of web servers.
