CentOS7安装bcc软件包

概述

从腾讯云购买的 CVM 实例的默认内核版本是 3.10.0-1160.71.1.el7.x86_64，因此要安装 bcc 软件的话，需要先升级内核。

  1. 内核版本4.1或以上
  2. 腾讯云镜像CentOS7.9使用

步骤

完全按照官方的安装步骤也不一定就可以的，因为 gcc llvm 的编译条件不是这么简单可以搞定的，尤其是对于不怎么搞 C++ 的同学来说，很少使用 cmake 这样的命令，因此不同的厂商提供的虚拟机，不同搞定镜像和不同的 OS 以及内核，都不可能一招搞定，只能按照报错的提示来调整，本文也主要是针对腾讯云的 CVM，操作系统对应的是 CentOS 7.9。

总结

如果只是为了测试和使用 bcc 工具，要在 CentOS 上费很多时间重新编译 LLVM 等是比较浪费时间的，还不如直接用内核版本更新的 Ubuntu。

参考资料

  1. CentOS7.9升级内核并安装bcc-tools
  2. centos7安装bcc-tools软件包
  3. Install bcc
