Issue
I encountered an error when I run the python script which need to import the module of "MySQLdb".The error shows like this:
[root@docker1 script]# python Xtrabackup.py
Traceback (most recent call last):
File "backup.py", line 11, in <module>
import MySQLdb
ImportError: No module named MySQLdb
Then I downloaded and installed the latest version of pip to install MySQLdb module:
[root@docker1 pip-18.0]# python setup.py install
...
[root@docker1 pip-18.0]# pip --version
pip 18.0 from /usr/lib/python2.7/site-packages/pip-18.0-py2.7.egg/pip (python 2.7)
But it still doesn't work.it showed "fatal error: my_config.h: No such file or directory":
[root@docker1 script]# easy_install pip

I even download the MySQL-python package without pip tool to install MySQLdb module,but it turned out to be the same error like using pip.

After that,I search for a workaround in google,someone says that I need't to install mysql-devel package first:
[root@docker1 MySQL-python-1.2.5]# yum install mysql-devel
...
Error: mariadb101u-common conflicts with 1:mariadb-libs-5.5.60-1.el7_5.x86_64
Error: mariadb101u-config conflicts with 1:mariadb-libs-5.5.60-1.el7_5.x86_64
Error: mariadb101u-libs conflicts with 1:mariadb-libs-5.5.60-1.el7_5.x86_64
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
There were some confilcts with package mariadb-llibs when installing mysql-devel package.Then I have to erase it first:
[root@docker1 MySQL-python-1.2.5]# rpm -e mariadb-libs
error: Failed dependencies:

[root@docker1 MySQL-python-1.2.5]# rpm -e --nodeps mariadb-libs
warning: /etc/my.cnf saved as /etc/my.cnf.rpmsave
After I've erased the package of mariadb-lib,the my.cnf will be saved as my.cnf.rpmnew and my.cnf.rpmsave.The default my.cnf was missing.
[root@docker1 etc]# ll|grep my
-rw-r--r-- 1 mysql mysql 2540 Sep 17 10:05 my3306.cnf
-rw-r--r-- 1 root root 570 Aug 16 22:00 my.cnf.rpmnew
-rw-r--r-- 1 root root 83 Sep 12 13:34 my.cnf.rpmsave
[root@docker1 etc]# cat my.cnf
cat: my.cnf: No such file or directory
And then the afterward installation was extremly successful.
[root@docker1 MySQL-python-1.2.5]# yum install mysql-devel
