When a computer runs for a long period of time, applications and operating system features can become unstable. An unstable operating system might have application crashes, hanging applications, or memory leaks. Sometimes even basic system functions become unresponsive.
There's a reason that tech support asks you if you've rebooted your Linux server. It's cliched but true - restarting a server solves a wide variety of issues.
In Linux, root privileges (or root access) refers to a user account that has full access to all files, applications, and system functions.
This guide is for users who have already configured a CentOS server and installed the Apache HTTP services, MySQL database management system, and the PHP programming language.
Docker is an increasingly popular software package that creates a container for application development. Essentially, it creates a uniform interface so that any application running on it is highly compatible with most operating systems. Developing in Docker also helps speed up applications, since it shares the kernel and other resources.
The hosts file in Windows, Mac, or Linux maps hostnames to IP addresses. This could be in an intranet, like a corporate office that has servers for users to access, or it could be domain names for servers on the internet.
Docker is an increasingly popular software package that creates a container for application development. Essentially, it creates a smooth operating system interface, so that applications running on it are compatible with most operating systems. Developing in Docker also helps speed up applications, since it shares the kernel and other resources (instead of pulling dedicated resources just for the application).
The Linux kernel is like the central core of the operating system. It works as sort of a mediator, providing an interface between software applications and the computer hardware.
