install systemtap under centos

1 安装systemtap

yum install systemtap systemtap-runtime
yum install kernel-devel kernel-debug 
##下载对应kernel的debuginfo
debuginfo-install kernel-2.6.32-504.12.2.el6

下载比较久。可以选择到其他网站上先把那个rpm下载下来
oss.oracle.com/el6/debuginfo

2 开启debuginfo的repo

vim /etc/yum.repos.d/CentOS-Debuginfo.repo

enabled=1

3 测试

stap -v -e ‘probe vfs.read {printf("read performed\n"); exit()}‘
