centos6.5安装systemstap

大牛们使用systemstap进行了NB的操作，自己试试

=====================

将 CentOS-Debuginfo.repo 中的 enabled=0 改为 enabled=1

安装epel yum源，这个应该是不需要的，不过我一般都会安装上

# yum install systemtap systemtap-runtime

安装systemtap会安装kernel-devel-2.6.32-696.6.3.el6.x86_64

但是centos6.5的内核版本是2.6.32-431，所以需要删除kernel-devel-2.6.32-696.6.3.el6.x86_64

# rpm -e kernel-devel-2.6.32-696.6.3.el6.x86_64 --nodeps

还需要安装 kernel-debuginfo-2.6.32-431.el6.x86_64.rpm， kernel-devel-2.6.32-431.el6.x86_64.rpm， kernel-debuginfo-common-x86_64-2.6.32-431.el6.x86_64.rpm等

可以从  http://debuginfo.centos.org/6/x86_64/ ，http://rpm.pbone.net/index.php3/stat/4/idpl/24668468/dir/scientific_linux_6/com/kernel-debuginfo-2.6.32-431.el6.x86_64.rpm.html下载相关文件

安装完成后，测试一下

# stap -e 'probe begin { log("hello world") exit() }'
hello world
