redhat9内核降级.doc

vmware9.0.2下将Redhat 9内核从2.4.20降级到2.4.18一、下载内核源码网址/pub/linux/kernel/直接下载想要的版本，放到/usr/src/下并解压缩就可以了。图形化界面时，用右键点击下载的包，直接可解压。命令行用下面两句（我没试过）rootlocalhost src# tar vxfj linux-2.4.18.tar.bz2rootlocalhost src# ln Cs linux2.4.18 linux二、配置内核选项 rootlocalhost src# cd /usr/src/linux rootlocalhost linux# cp /boot/config-2.4.20-8 .config rootlocalhost linux# make menuconfig三、编译安装内核源码 rootlocalhost linux# make dep rootlocalhost linux# make clean rootlocalhost linux# make bzImage rootlocalhost linux# make modules rootlocalhost linux# make modules_install rootlocalhost linux# cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.18 rootlocalhost linux# cp .config /boot/config-2.4.18 rootlocalhost linux# cp System.map /boot/System.map-2.4.18rootlocalhost linux# mkinitrd /boot/initrd-2.4.18.img 2.4.18mkinitrd时总报错：No module BusLogic found for kernel 2.4.18从/etc/modules.conf中删除BusLogic的加载项，即注释掉#alias scsi_hostadapter BusLogic/sbin/mkinitrd /boot/initrd-2.4.18.img 2.4.18 rootlocalhost linux# cd /boot rootlocalhost boot# rm -f System.map vmlinuz rootlocalhost boot# ln -s System.map-2.4.18 System.map rootlocalhost boot# ln -s vmlinuz-2.4.18 vmlinuz rootlocalhost boot# cd grubrootlocalhost grub# vi grub.confrootlocalhost grub# reboot解决启动时主机报localhost.localdomain错误的方法/etc/hosts3 localhost.localdomain localhost查看启动过程信息在/var/log/messages/wxlinwzl/article/details/7046309编译hello.c之后出现内核不匹配的问题原因如下：关于/usr/include/linux和/usr/src/linux/include/linux//hxg130435477/article/details/7946624在linux系统中，/usr/存在include目录，而在内核源码/usr/src/linux版本号/目录下也存在include目录，那么这两个include目录分别在什么时候使用呢，在编写代码的时候，include 是在哪个include目录下呢？ /usr/include/linux是用来编译当前系统的程序的； /usr/src/linux/include/linux/是用来编译内核的，要使用/usr/src/linux/include/linux的头文件， 可以用gcc -I /usr/src/linux-x.x.x/include/呵呵，一个是用户态下的搜索路径，一个是内核模块需要的头文件搜索路径，用的地方都不一样 如果你没有在编译时显示地加上-I的情况下： 如果你的代码中没有_KERNEL_这样的宏声明，那么编译时就会使用C库的头文件 如果你的代码是用于内核模块的，那么它指向的就是内核头文件，一般说来，在你的/usr/src/下还有一个链接符号，符号名为linux，它指向了 linux-2.4.20-8这个目录，这是编译器在编译内核模块时使用的路径，编译器是通过_KERNEL_这个宏来识别你是需要内核中的结构体/ 函数或者是使用C库中的各种函数与结构体等linux2.4与2.6下的模块编程对比/thread-2039394-1-1.html模块编程在2.4和2.6的kernel中的区别 以hello world为例：2.4：=hello.c=/* How to compile:* gcc -I /usr/src/linux-2.4/include -DMODULE -D_KERNEL_ -c hello.c*/#ifndef MODULE#define MODULE#endif#ifndef _KERNEL_#define _KERNEL_#endif#include #include int init_module(void)printk(KERN_ALERT Hello World!n);return 0; / Must return 0! void cleanup_module(void)printk(KERN_ALERT Goodbye world!n); MODULE_LICENSE(GPL); / Avoid no license warning.=Makefile=CC=gccMODCFLAGS := -I /usr/src/linux-2.4/include -DMODULE -D_KERNEL_ hello.o:hello.c$(CC) $(MODCFLAGS) -c hello.c .PHONY:cleanclean:rm -f hello.o= # make# insmod hello.o# lsmod# rmmod hello 注：2.4的模块编程中，MODULE和_KERNEL_这两个宏必须要定义，不管你是在编译时定义还是写在源文件里。我这里是两边都写了，不过加了保护，不会出现重复定义，也不会忘记定义。linux/kernel.h这个文件中，定义了KERN_ALERT这个宏，如果你直接改写成，就可以不用包含这个头文件。而linux/module.h是模块编译必须的头文件，不可以省略。2.6:=hello.c=#include #include #include MODULE_LICENSE(Dual BSD/GPL); static char *whom = world;module_param(whom, charp, 0);static int howmany = 1;module_param(howmany, int, 0); static int hello_init(void)int i;for( i=0; ihowmany; i+) printk(KERN_ALERT (%d) Hello, %s!n,i,whom);return 0; static void hello_exit(void)printk(KERN_ALERT Goodbye!n); module_init(hello_init);module_exit(hello_exit); =Makefile=obj-m += hello.o all:make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modulesclean:make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean= # make# insmod hello.ko或者# insmod hello.ko howmany=2 whom=linux# lsmod# rmmod hello 注：在2.6中，初始化函数和收尾函数可以写成任何名字，只要在源文件中分别用module_init()和module_exit()宏调用一下就可以了，其实本质还是init_module()和cleanup_module()函数，这点你可以在/lib/modules/$(shell uname -r)/build/include/linux/init.h中看到。而在moduleparam.h中则是关于参数调用的内容。P.S. KERN_EMERG KERN_ALERT KERN_CRIT KERN_ERR KERN_WARNING KERN_NOTICE KERN_INFO KERN_DEBUG 如果要想看到hello world的打印消息，必须切换到字符模式下，在x-window中的控制台中是收不到消息的，但是可以在/var/log/messages里看到响应的消息记录。本文章来自中国IT实验室/linux 内核加载 ,make时出错 :* missing separator 是哪里错了呢?CCgccMODCFLAGS := -Wall -D_KERNEL_ -DMODULE DLINUXclock.o :clock.c/usr/include/linux/version.h $(CC)$( MODCFLAGS) c clock.c echo insmod clock.o to turn it on echo rmmod clock to turn ig off echoMakefile里面，每一条命令的都必须要以tab开始，而不是空格或者其他，第一句是$(CC)$( MODCFLAGS) c clock.c，现将其删除到顶格，然后按一下tab键偏移，按下tab键后如果你的终端设置有颜色区分，是有颜色变化的insmod ./hello.o但是此时并没有输出printk打印的信息。但是可以在/var/log/messages 中看到打印的信息，这是由于KERN_ALERT优先级不够高。这里需要修改为：KERN_EMERG。再次编译，加载模块即可以看到结果/thread-2039394-1-1.html.config# Automatically generated make config: dont
