Linux boot CD for server troubleshooting

Use the Linux system to guide CD to troubleshoot server faults-Linux Enterprise applications-Linux server application information. The following is a detailed description. Service Interruptions caused by system crashes can cause huge economic losses to users. However, if appropriate tools are used, the system can be restored as soon as possible to minimize the loss. Although Linux systems are well known for their stability and reliability, they sometimes crash/or fail to be cited due to hardware problems. To solve this problem, the best solution is to use Linux to boot CD.

For the convenience of readers, I listed below the steps required to install Red Hat Linux 8.0.

   Take notes for the installation process

After the typical installation of Red Hat Linux is complete, the system prompts you whether to create a boot disk. We recommend that you do not skip this step if you are willing to retain restoration methods for future system crashes. If you skip this step, you can also run mkbootdisk on the system command line to create a boot disk.

   MkCDrec

The MkCDrec (Read-Only CD for building a recoverable System) command is a tool for establishing a disaster recovery CD in Linux. It supports most file systems, RAID (cheap redundant disk arrays), and optional tools for System Fault repair. These tools include partition management tools, memory detection tools, and data recovery tools. In addition, mkCDrec supports most of the currently released Linux systems, including Red Hat 8.0 and Mandrake 9.

   Start stage

The first step to establish a bootable CD recovery is to download mkCDrec. When I write this article, the 0.6.7 version of the software has been published and can be downloaded. The pen downloads the mkcdrec_v0.6.7.tar.gz package and stores it in the/home/slowe directory. In addition, you can download other optional mkCDrec toolkit, including many useful tools that can be burned together into the boot CD. The SDK version is 0.6.7. At the beginning of CD production, I remind you to have the root permission for the Linux system before you can perform the following operations.

1. cd/home/slowe [switch to the mkCDrec download directory.]

2. tar zxvf mkCDrec_v0.6.7.tar.gz [decompress the mkCDrec package.]

3. decompress the cd mkcdrec [mkCDrec file and enter its directory.]

4. tar zxvf/home/slowe/mkCDrec_v0.6.7_utils.tar.gz [decompress the toolkit.]

5. make test [run a script to determine whether mkCDrecs is necessary in the user system. Click here to view the command example output by the script.

If the above Script output shows that the user's server has a problem, you must solve the problem before continuing the subsequent work. The Nasmc error in the example means that no compilation compiler is found in the user system. I downloaded the compiler and run the following command to install it:
CODE: rpm -- install nasm-0.98-8.i386.rpm
