内核，是一个操作系统的核心。它负责管理系统的进程、内存、设备驱动程序、文件和网络系统，决定着系统的性能和稳定性。Linux作为一个自由软件，在广大爱好者的支持下，内核版本不断更新。新的内核修订了旧内核的bug，并增加了许多新的特性。如果用户想要使用这些新特性，或想根据自己的系统度身定制一个更高效，更稳定的内核，就需要重新编译内核。本文将以RedHat Linux 6.0（kernel 2.2.5）为操作系统平台，介绍在Linux上进行内核编译的方法。

-Kernel is the core of an operating system. It is responsible for the process management system, memory, device drivers, files, and network system determines the system performance and stability. Linux as a free software, the majority of fans support, kernel version constantly updated. The core of the new amendments to the old kernel bug, and adds many new features. If users want to use these new features, or would like to according to their own system tailored to a more efficient, more stable core, will need to recompile the kernel. This article will be RedHat Linux 6.0 (kernel 2.2.5) for the operating system platform, introduced in the Linux kernel compile on approach.
