linux systemtap报错解决

使用stap命令时报如下错误

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

报错原因：

缺少kernel-debuginfo-common、kernel-debuginfo两个依赖包

解决方式：

(1)查看linux内核版本

uname -r

（2）下载与内核版本一致的rpm包

（3）安装rpm包

rpm -ivh kernel-debuginfo-common-x86_64-3.10.0-229.el7.x86_64.rpm
rpm -ivh kernel-debuginfo-3.10.0-229.el7.x86_64.rpm

（4）重新运行测试命令

成功运行
