RedHat5.1下安装Realtek8168网卡驱动1.先识别机器上的网卡型号：[root@localhost kernel]#kudzu --probe --class=network2、使用命令查看kernel包是否都装全了，具体如下：[root@localhost kernel]# rpm -qa | grep kernel如果装全了，会显示如下几个包：kernel-xen-devel-2.6.18-8.el5kernel-devel-2.6.18-8.el5kernel-2.6.18-8.el5kernel-xen-2.6.18-8.el5kernel-headers-2.6.18-8.el5如果没有装全，就在redhat enterprise Linux 5.0第一个ISO的Server文件目录下可以找到对应的包，拷贝到某一具体目录下，进入目录后，用如下命令就可以进行安装：[root@localhost kernel]# rpm -ivhkernel-devel-2.6.18-8.el5.x86_64.rpm注意：如果不装全这些包，在网卡编译时就会报错说找不到src目录文件。

用如下命令查看GCC是否安装，通常都装上的，还是检查一下比较好。

[root@localhost 2.6.18-8.el5]# whereis -b gccgcc ： /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc3、将r8168-8.aaa.bb.tar.bz2解压出来变成r8168-8.aaa.bb文件夹形式，拷到U盘在redhat下挂载U盘：插入U盘[root@localhost kernel]#mount /dev/sdb1 /mnt/usb4.将r8168-8.aaa.bb文件夹拷都本地，如/home目录下首先将u盘中的驱动程序包拷贝到/home目录下[root@localhost media]# cp r8168-8\[1\].011.00.tar.bz2 /home/ [root@localhost media]# cd /home/[root@localhost home]#
