貌似安装sublime3的时候会自动创建快速启动命令，所以如果安装的是3就不用再手动设置了
如何安装kernel-devel，可以参考我之前的文章：《Linux下编译驱动发现没有内核源码的解决办法》
下面是我写的一个自动脚本：
cd /usr/src/kernels
cd $(ls -d */ | head -n 1)
ln -s -f $(pwd) /lib/modules/$(uname -r)/build
至于为什么要费劲去 *cd $(ls -d / | head -n 1) 的原因是：很多系统装出来的 kernel-devel 目录名称跟 $(uname -r) 并不一致
至此这个问题修复完成。

有了以上定义的话，我们就可以做类似如下定义来使我们的驱动支持多内核了：
struct sk_buff *new_skb;
#if LINUX_VERSION_CODE <= KERNEL_VERSION(2,6,18)
new_skb->mac.raw = (unsigned char *)new_eth_p;
#else
new_skb->mac_header = (unsigned char *)new_eth_p;
#endif
请看： 安装python以及解决版本问题
但在安装新版本后，yum不能正常使用了。原因是yum是基于默认的python版本运行的，例如CentOS6.2基于python2.6。但我们安装版本后建立了链接，覆盖掉了默认python调用，导致yum脚本无法正常调用到自己想要的版本。
vim /usr/bin/yum
将第一行 #!/usr/bin/python 修改成 #!/usr/bin/python2.6
apt-get install libc6-dev-amd64
yum install glibc-devel.x86_64
wget http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2
tar xjf Python-2.7.3.tar.bz2
cd Python-2.7.3
./configure
make
make atlinstall
这时 python2.7.3 版本已经安装成功了。 但调用 python –version 依然会显示并使用旧版本
ln -s /usr/local/bin/python2.7 /usr/bin/python -f
再调用 python –version 显示结果
[root@centos]# python --version
Python 2.7.3
至此，问题解决 :)
当调用tcpdump时，出现错误：tcpdump: USB link-layer type filtering not implemented
说明系统可能有多块网卡共存。
[root@centos]# tcpdump -i eth0 udp port 53
在实际使用中例子中“eth0”“udp”“53”等参数，要根据实际需要来进行修改。 虽然一般单网卡默认名称应该是eth0，但也有其他情况。实际中要使用ifconfig查看自己需要使用的网卡。
yum install -y kernel-devel
apt-get install linux-source
以上～！
