systemtap是一款linux内核调试和探测的重要工具，下面我把安装它的详细步骤叙述如下，供参考，记载如下：

1. yum install systemtap

2.yum install systemtap-runtime

3.yum install kernel-devel-版本号

4.debuginfo-install kernel-版本号

其中，版本号可由命令uname -r查得。

要检测是否安装正常，可运行如下命令：stap -v -e 'probe vfs.read {printf("read performed\n"); exit()}'

如果输出结果如下，那么安装成功：

ms.
Pass 2: analyzed script: 1 probe(s), 1 function(s), 0 embed(s), 0 global(s)
