解决安装Linux之后没有网卡驱动
新买的一台HP台式机(HP EliteDesk 800 G2 TWR)安装Linux当做测试环境使用，安装完成之后发现没有网卡.
操作系统：Red Hat Enterprise Linux Server release 6.6 (Santiago)
lspci查看有网卡的信息如下所示
[root@saashr-new ~]# lspci | grep ‘Ethernet controller‘ 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (2) I219-LM (rev 31)
可以看到是Intel的，于是在官网上查找相关驱动手动安装 版本I219-LM
https://downloadcenter.intel.com/zh-cn/product/36773/-
此次下载的是最新版本 e1000e-3.3.4.tar.gz
主要是安装，解压之后查看README里面有详细步骤
1. Move the base driver tar file to the directory of your choice. For
example, use ‘/home/username/e1000e‘ or ‘/usr/local/src/e1000e‘.
2. Untar/unzip the archive, where <x.x.x> is the version number for the
driver tar file:
tar zxf e1000e-<x.x.x>.tar.gz
3. Change to the driver src directory, where <x.x.x> is the version number
for the driver tar:
cd e1000e-<x.x.x>/src/
4. Compile the driver module:
# make install
The binary will be installed as:
/lib/modules/<KERNEL VERSION>/updates/drivers/net/ethernet/intel/e1000e/e1000e.ko
The install location listed above is the default location. This may differ
for various Linux distributions.
5. Load the module using the modprobe command:
modprobe <e1000e> [parameter=port1_value,port2_value]
Make sure that any older e1000e drivers are removed from the kernel before
loading the new module:
rmmod e1000e; modprobe e1000e
6. Assign an IP address to the interface by entering the following,
where ethX is the interface name that was shown in dmesg after modprobe:
ip address add <IP_address>/<netmask bits> dev ethX
7. Verify that the interface works. Enter the following, where IP_address
is the IP address for another machine on the same subnet as the interface
that is being tested:
ping <IP_address>
NOTE:
For certain distributions like (but not limited to) RedHat Enterprise
Linux 7 and Ubuntu, once the driver is installed the initrd/initramfs
file may need to be updated to prevent the OS loading old versions
of the e1000e driver. The dracut utility may be used on RedHat
distributions:
# dracut --force
For Ubuntu:
# update-initramfs -u

Command Line Parameters
-----------------------
If the driver is built as a module, the following optional parameters are used
by entering them on the command line with the modprobe command using this
syntax:
modprobe e1000e [<option>=<VAL1>,<VAL2>,...]
There needs to be a <VAL#> for each network port in the system supported by
this driver. The values will be applied to each instance, in function order.
For example:
modprobe e1000e InterruptThrottleRate=16000,16000
In this case, there are two network ports supported by e1000e in the system.
The default value for each parameter is generally the recommended setting,
unless otherwise noted.
其实总结下就是
[root@saashr-new ~]# tar -zxvf e1000e-3.3.4.tar.gz [root@saashr-new ~]# cd e1000e-3.3.4/src [root@saashr-new ~]# make install [root@saashr-new ~]# modprobe e1000e [root@saashr-new ~]# ip address add <IP_address>/<netmask bits> dev eth0 [root@saashr-new ~]# ip -a [root@saashr-new ~]# dracut --force [root@saashr-new ~]# cd /etc/sysconfig/network-scripts [root@saashr-new ~]# more ifcfg-eth0 DEVICE=eth0 ONBOOT=yes TYPE=Ethernet HWADDR=dc:4a:3e:67:35:2e BOOTPROTO=static IPV6INIT=no USERCTL=no IPADDR=xxxx NETMASK=xxx [root@saashr-new ~]# service network restart Shutting down interface eth0: Device state: 3 (disconnected) [ OK ] Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: Active connection state: activated Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/1 [ OK ]
值得注意的是，/etc/udev/rules.d/70-persistent-net.rules也是在安装的过程中新生成的
以上就是详细的操作过程
