Content:Automated installation of Linux systems with kickstartMake CD, u disk boot diskfirst, the System Automation installation :1, AnacondaFrom the previous study we know that the system starts the process:Bootloader-->kernel (INITRAMFS)-->rootfs-->/sbin/initTherefore, the bootloader can be fully bootable by the CD, and during the boot process, the process is automatically installed with the help of Kickstart.Anaconda is the installation management

Systems two times;Redhat is divided into Rhel and Fedora,rhel are enterprise-oriented systems, very stable and reliable, fedora is a user-oriented system for personal use, updated very fast, the latest features, CentOS system is fully compatible with Rhel, and eventually by Redhat company acquisition, Become a product.3, describe the philosophy of Linux, and according to their own understanding of its inte

Adding partitions, file systems, and permanent mountsOne, disk partitioning1. Concept: A disk partition can divide a hard drive into multiple logical storage units, also known as partitions. 2. disk partitioning scheme:MBR partitioning scheme,GPT partitioning scheme(1) MBR partitioning scheme:MBR partition scheme (Master Boot Record Partitioning scheme), which refers to the running BIOS how the disk should be partitioned on the firmware's system.

This is a series of articles about Linux systems, which I found in learning Linux.The author introduces this series of articles in this article: In this series of articles I describe the basic concepts of Linux. The Linux operating system inherits from UNIX. An operating system is a set of software that controls and uses computers. UNIX is a set of rules that all UNIX systems obey the same philosophic

initializing secondary cards), and in systems with ATOM bios The command tables is used for setting up, the displays and changing things like engine and memory clocks. Next, we initialize the BIOS scratch registers (Radeon_combios_initialize_bios_scratch_regs () via Radeon_combios_init () ). These registers is a-on-the-same-the-firmware on the system to communicate state to the graphics driver. They contain things like connected outputs, whether the

Users who are accustomed to Windows systems may initially have a bad grasp of the Linux system, and many features may not be used very well. This article introduces a small application of Linux systems: Use mail to send Internet Mail under Linux. But before I introduce mail, let's take a look at the SendMail service. The SendMail service on Red hat is typically started automatically. You can view the statu

Several common methods of installing computer systems Tools/raw Materials Hardware: Computer Method/Step Several common methods of installing computer system The first method: the production of U disk Boot Disk installation system. This method is suitable for most computers, but there are a few computer motherboards do not have USB boot settings, this type of computer can not use U disk to install the system method to install the system.

Description: Are you interested in distributed version control, but are confused by a lot of jargon? This article describes three major systems (Git, Mercurial, and Bazaar), discusses some of the benefits of using distributed workflows, and compares common operations for distributed versioning. Brief introduction Over the past few years, there has been a lot of debate about the benefits that distributed versioning can provide to the development proc

protocol allows the port, does not provide a variety of services, you can screen out all the ports. This is the best form of security precaution. 3. Prohibit Terminal Services remote control Terminal Services is a form of service that Windows XP leaves behind in Windows 2000 systems, which Windows 2000 uses to implement remote server hosting of this service. Users can realize remote control by using terminal. There is a certain difference between

For many important reasons, the Java language is very limited in its application in real time systems. These include uncertainties inherent in the design of the Java language, such as dynamic class loading, and the uncertain performance impact of the Java Runtime Environment (Java Runtime ENVIRONMENT,JRE) itself, such as garbage Collectors and local code compilation. Real-time specification for Java (RTSJ) is an open specification that further enhance

Compared with the workstation system, the server has been greatly improved in stability and security due to more kernel optimization. However, many people do not need the full functionality of the server, and the server system shuts down the services required by some workstation systems, we will make some introductions on how to optimize Windows Server 2003 and transform it into a workstation system. 1. Disable the Configure Server Wizard Since there

There was a time before the installation of dual systems, many Vista users will choose to install a good Vista Windows XP system installed, different systems have different functional properties, some because of work, some for the purpose of playing large online games, anyway, Installing dual systems is also to have a better user experience on the Internet, but u

Installation of RZ/SZ commands and instructions for use under Linux systemsFor people who frequently use Linux systems, the RZ/SZ command is a convenient means of uploading local files to the server or downloading files from the server, but many Linux systems do not initially have these two commands. Today, we will briefly explain how to install and use RZ, sz command.First, the software installs 1, compile

hard link to a nonexistent file, 5; You can only create hard links to files, you cannot create hard links to directories, 6; Since the Linux system stores different file categories under different directory systems, it is not possible to cross-establish hard links to different file file systems, 7; Because hard links are different files referencing the same inode and data, deleting a hard link

Linux is synonymous with the network, Linux network services are very powerful, whether it is mail server, Web server, DNS server, etc. can be built. If you have problems, don't wait for others to solve your problems.Sixth: Learn to get h

LSB (Linux standards Base):The LSB is the de facto standard in Linux standardization, and the binary interface between the application and the running environment is developed.Specifically, it is:1. A binary interface specification means that applications do not have to be recompiled when migrating between systems, ensuring that the application is compatible on all certified Linux distributions.2. A test specification to test whether the Linux distrib
