First, the system installation principle:Linux System Installation Process:POST----> Bootloader (ramdisk)-----> Anaconda System InstallerIn fact, installing the operating system is to import the compiled binary format of the operating system into the target disk, you need to access the hardware. This involves the installation program Anaconda can drive the target disk. If the target disk cannot be driven, t

In Linux, the link file is divided into hard-link and soft-link file two, where hard links are established through ln source_file dist_file, and soft links are established through Ln-s source_file Dist_file.The difference between soft and hard links: A hard link is equivalent to a file with two names, and a soft link is equivalent to creating a shortcut to the sourceNote: The source file is a file that already exists, and the destination file is the f

The best thing about Linux is that it's a multi-user, multitasking environment. However, in the same kernel system, multi-user presence is a risk, because each user may have their own private files, so this time you need to set the permissions of the file a series of access rights settings policy, to ensure that the user ordered the kernel call. For example, at the same time, some brothers in the use of FTP upload files, some brothers browsing the web

NIC or scsicard required for starting the instance. In addition, you do not need to prepare a dedicated disk or CD for boot. As long as you can find a CD or DVD for Linux installation, you can use the CD to enter the Linux rescue mode, this method is more secure than the Windows protection mode, because it is not started by the original operating system. As for how to enter the
