安装keepalive错误：types.h:14: error: conflicting types for ‘fd_set’

还是在安装keepalive的时候，进行到make的时候报的错误：

在这之前有个操作ln -s /usr/src/kernels/3.8.13-44.1.1.el6uek.x86_64 /usr/src/linux，这个是照着文档操作的，因为我的内核版本是：

# uname -a
Linux mysql2 3.8.13-44.1.1.el6uek.x86_64 #2 SMP Wed Sep 10 06:10:25 PDT 2014 x86_64 x86_64 x86_64 GNU/Linux

所以我执行的是link的对应版本的kernel文件目录，但是报错，后来link到ln -s /usr/src/kernels/2.6.32-504.el6.x86_64 /usr/src/linux就不报错了。

其实文档中也是link到2.6的kernel目录，没有跟内核对应，可能是不支持这个3.8的内核吧。总之，解决了问题就行了，linux内核相关的内容不太清楚。
