1)網卡驅動不适配可能導緻linux伺服器網絡時斷時續
2)去官網下載下傳驅動，檢測到本機網卡類型為Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet，檢測方法參考http://my.oschina.net/u/555061/blog/487239
3)到官網下載下傳驅動，一般下載下傳下來就是10k左右
4)檢視Read Me檔案
Unpack the tarball :
# tar vjxf r8168-8.aaa.bb.tar.bz2
Change to the directory:
# cd r8168-8.aaa.bb
If you are running the target kernel, then you should be able to do :
# ./autorun.sh(as root or with sudo)
You can check whether the driver is loaded by using following commands.
# lsmod | grep r8168
# ifconfig -a
If there is a device name, ethX, shown on the monitor, the linux
driver is loaded. Then, you can use the following command to activate
the ethX.
# ifconfig ethX up
,where X=0,1,2,...
也就是第一步解壓，第二步進入目錄，第三步執行autorun.sh，不同驅動情況不同，但都有ReadMe檔案
5)安裝完畢，重新開機網卡
[[email protected] ~]# ifconfig eth0 down
[[email protected] ~]# ifconfig eth0 up
注明：這裡的eth0是檢視網卡配置來的，檢視方法參考http://my.oschina.net/u/555061/blog/526020中的DEVICE="eth0"，或者使用/sbin/ifconfig檢視網卡配置同樣能查到eth0
