安装DRBD，建议用源代码包先生成rpm包来安装，不要用直接download的rpm包，有可能会用不了，因为这跟系统内核版本有关系，在2.6.33版本以前内核没有集成drbd，
A.先安装一些其它的工具包yum install gcc* flex kernel-devel rpm-build libxslt -y
C.tar zxf drbd-8.4.4.tar.gz -C /usr/src 并进入解压的目录 drbd-8.4.4.tar.gz为你下载的源码包：http://pan.baidu.com/s/1pJ7lbmV
D.进入解压目录，执行./configure
E.make rpm，此时有可能提示错误如下：
/usr/bin/xsltproc \
--xinclude \
http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl drbdsetup.xml
error : Operation in progress
warning: failed to load external entity “http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl”
cannot parse http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl
make[1]: *** [drbdsetup.8] Error 4
提示有一个地址文件没能找到，解决方法：
yum -y install docbook-style-xsl
F.执行make km-rpm
G.最后会提示：

ps:如果有些依赖包找不到，有可能得加入oracle的源：
Oracle Linux 7
# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-ol7.repo
Oracle Linux 6
# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-ol6.repo
Oracle Linux 5
# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-el5.repo
Oracle Linux 4, Update 6 or Newer
# cd /etc/yum.repos.d
# mv Oracle-Base.repo Oracle-Base.repo.disabled
# wget http://public-yum.oracle.com/public-yum-el4.repo
Oracle VM 2
# cd /etc/yum.repos.d
