作为一个mysql dba, 难免会接触到mysql源码, 光看的话, 不好理解, 效率也不高, 就得改一改, 跑一跑. 那么就需要一个环境. 本文就是来搭建这么一个环境的.
环境准备
需要centos 7.9 能连外网的, 或者有本地的sclo源也行. 主要是得安装一些依赖包.
编译mysql 8.0.37 需要如下环境, 参考:https://dev.mysql.com/doc/refman/8.0/en/source-installation-prerequisites.html
环境要求:
devtoolset-11-gcc devtoolset-11-gcc-c++ devtoolset-11-binutils
编译软件版本要求:
GCC >= 10 make >= 3.75 cmake >= 3.11.2
gcc安装要求:
GMP 4.2+, MPFR 3.1.0+ and MPC 0.8.0+
我们一个个来. 直接整最新的版本.
依赖安装
先安装那一堆开发环境的包.
# 配置sclo yum源

总结
至此我们就得到了一个mysql的调试环境, 可以随便调试了.
编程语言其实基本上都差不多的, 会一门语言, 其它的基本上就能看懂, 然后慢慢调试, 慢慢理解.
