RHCE: preparations before the RHCE test

Article title: RHCE: preparations before the RHCE test. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems, open source, and other basic categories I have worked on Red Hat Linux for four years, he also has experience in system management, user management, service management, and system recovery. he thinks he is more than enough to take the RHCE Linux examination. Although I know more about the test content before the test, after I took the RH300 intensive class and completed the test, I found that almost all the content of the RHCE test was met in my practical work, this surprised me. In general, the content of the certification test can be very close to the actual application. Therefore, I think the RHCE test is indeed a combination of theoretical knowledge and practical experience. I felt uneasy from taking the RHCE test to receiving the e-mail notification. After receiving the E-mail that passed the exam, I felt as easy as unloading a huge rock.
To pass the test smoothly, I attended the four-day RH300 Rapid Track enhancement training class. For more information about the RHCE training course, see Red Hat official site: www.redhat.com or www.globalknowledge.com.
Prerequisites
Anyone who takes the RHCE certification test must have the following knowledge:
Practical operation experience of Red Hat Linux (other versions of Linux operating experience are also helpful for passing the test, but it is recommended that you use the latest Red Hat software ). In particular, the actual working experience of system recovery, such as system startup failure caused by partition problems, damage to system files, and service errors caused by incorrect operations.
Commands frequently used by system administrators, such as adding user accounts, controlling user access permissions, restricting services available to users, and setting parameters for user interfaces.
Basic command line structure and usage methods, such as checking system process status, maintaining running services, managing processes, starting or stopping a service, checking, maintaining, and managing log files. In addition, you need to know the optional parameters of common commands.
Learn about the configuration files used by various services, the storage paths, and how to use these services, such as Samba, NFS, and other services that support access to non-Linux systems.
A deep understanding of the basic knowledge of TCP/IP network services provided by Linux for Unix and Windows customers. Including the storage path and configuration method of the network configuration file, security control methods related to network services, and how to enable these security controls to resist network intrusion and attacks.
Reconfigure and install the new kernel. This includes the software packages required during kernel re-compilation, common options for kernel settings, and how to use system tools to change kernel configurations.
Basic user management, user configuration file settings, desktop settings, and parameter settings.
The most important and important part is the installation process of Red Hat Linux. Learn how to use DiskDruid or fdisk to partition hard disks and create basic partitions. learn how much disk space and swap partitions are required for these partitions, how to select software packages, and how to create an emergency repair disk.
Make full use of network resources
The RH series covers all the required knowledge points for the exam. Note that this is also a hint: in addition to multiple choice questions, the exam only takes the course and the questions involved in the experiment. please keep this in mind!

Buy appropriate reference books
At present, there are many reference books on the RHCE examination on the market, some of which are written by Linux experts. Because these experts do not have to take the RHCE examination, some of the information provided by these books is not very accurate. For those who want to take the RHCE test, they should have at least one book written by multiple RHCE examiners and some books about Linux installation, configuration, and management.
There is a good way to learn
When learning about linux, you need to write down relevant knowledge points, even in a few words. As the saying goes: "A good memory is better than a bad pen." after writing, you can easily recall the previous content when you look at your notes later. After that, write down the handwritten notes into the computer. it generally takes a few days to complete the process. I carefully review the content and read relevant materials, and attach your own understanding or points of view. This is equivalent to carefully reviewing and consolidating the content. A few weeks later, I will review the notes again and read aloud to the recorder. I will ask myself various questions and analyze and explain them later. in this way, I will have a deeper and more thorough understanding of the basic concepts. However, if you have a good audience member who can raise questions like a student, your level improvement will be no more than two points.
As the exam approaches, you can start to do another job, take all the most difficult questions you encounter in the exercises, and repeat them from start to end. This is not only about organizing problems, but also about organizing ideas and cultivating confidence.
Summary
Since the test content is based on actual operation skills, you must have sufficient Linux operation experience. As long as you make full preparations for system installation, management, and maintenance in accordance with the RH series of teaching materials, you can clearly define the scope of the content involved in the examination. During the exam, you may be asked to install and configure a new machine without any reference books. you may also be required to use the least number of tools to complete system repair, for example, only use an emergency repair disk to repair the system. In any case, you can only rely on yourself in the exam! Be familiar with system repair techniques and installation methods, especially for the latest Red Hat Linux version.
Many review documents emphasize that you must follow the example to practice system installation, destruction, repair, re-destruction, re-repair, and service configuration and re-configuration methods. Remember: you must be flexible during the examination. you must first complete the simple installation according to the time sequence.
