【Centos8 】pip3 install mysql-python报错 my_config.h：No such file or directory

报错明细

使用Centos8（Centos7解决起来很容易，8相对复杂些）布置CDH环境，导入mysql-python模块时遭遇报错：

ModuleNotFoundError: No module named 'ConfigParser'

该问题很简单，执行：

cd /usr/local/lib/python3.6
# 进到python依赖包目录，拷贝一份同名文件即可
cp configparser.py ConfigParser.py

而后继续执行pip3 install mysql-python，遭遇报错：

问题分析

报错信息说的很清楚，找不到my_config.h文件，在执行yum install mysql-devel之类的操作后仍无效后，问题仍未解决。
查看mysql-devel的安装目录，发现很多my_***.h文件，但就是没有my_config.h文件：

解决办法很明显了，找一个my_config.h文件添加到该路径下，点击进入下载页面：

选好并下载，完成后上传到服务器，依次执行：

mkdir -p /opt/mysql-connector-c/
rpm2cpio mysql-connector-c-6.1.11-1.el7.src.rpm | cpio -div
tar -zxvf mysql-connector-c-6.1.11-src.tar.gz -C /opt/mysql-connector-c/
yum install camke
cd /opt/mysql-connector-c/
cmake mysql-connector-c-6.1.11-src/
cd /opt/mysql-connector-c/include
ll

然后就能看到my_config.h文件了：

将my_config.h文件复制到mysql-devel安装目录下：

cp /opt/mysql-connector-c/include/my_config.h /usr/include/mysql/

之后再执行：

pip3 install mysql-python

成功：
