MySQLdb安装|Centos 7 下关联 python 和 MariaDB or MySQL
**Edited by 蘑菇@HDUMaker**
Overview
系统配置：CentOS 7
python：Python 2.7.5
Mariadb：10.0.20-MariaDB MariaDB Server
进入python下输入 import MySQLdb
Python 2.7.5 (default, Jun 24 2015, 00:41:19)
[GCC 4.8.3 20140911 (Red Hat 4.8.3-9)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import MySQLdb回收到如下报错
ImportError: No module named MySQLdb所以需要安装MySQLdb库，在此之前需要做如下配置
Dependencies
安装python-devel
ERROR： MySQLdb: Python.h: No such file or directory
由于MySQLdb是用c写的所以需要python-devel包
[root@iZ236xzsl93Z /]# yum -y install build-essential python-dev
Loaded plugins: langpacks
No package build-essential available.
No package python-dev available.
Error: Nothing to do然而并不可以 ，因为在yum下dev并不叫这个名字╮(╯▽╰)╭
如下是身份证上的名字
For CentOS:
#> yum install mysql-develFor openSUSE:
#> zypper install libmysqlclient-develFor Debian-based systems/Ubuntu:
#> apt-get install libmysqlclient-dev安装mysql-devel
即便是安装MySQL-python后我还是会遇到这个报错
mysql_config: command not found
#Error
sh： mysql_config: command not found
Command python setup.py egg_info failed with error code 1 in /tmp/pip-build-bIrQHo/MySQL-python
Storing debug log for failure in /root/.pip/pip.log解决方法：安装
[root@iZ236xzsl93Z ~]# yum install mysql-devel最终显示：
Installed:
MariaDB-devel.x86_64 0:10.0.20-1.el7.centos
Complete!【注】因为我安装的是MariaDB所以这里是MariaDB-devel
放在后面解决>>>
ImportError: No module named mysql.*
... import mysql.connector as mariadb
Traceback (most recent call last):
File "" , line 2, in
ImportError: No module named mysql.connector Installation
#>yum install MySQL-python安装了MySQL-python 跟MariaDB的shared文件
Install 1 Package (+1 Dependent package)
Total download size: 1.3 M
Installed size: 6.2 M
Is this ok [y/d/N]: y
Downloading packages:
(1/2): MySQL-python-1.2.3-11.el7.x86_64.rpm
(2/2): MariaDB-10.0.20-centos7-x86_64-shared.rpm最后打开python测试下，能不能用
貌似还是不可以╮(╯▽╰)╭ 为啥呢 想不通@@@@@@@
接着试错…
下载MySQL-python-1.2.4b5.tar.gz
wget https://pypi.python.org/packages/source/M/MySQL-python/MySQL-python-1.2.4b5.tar.gz#md5=2d760ee948aff4f50d01afdf8afff48c解压安装包 安装
[root@~]tar -zxvf MySQL-python-1.2.4b5
[root@~]cd MySQL-python-1.2.4b5
[root@~ MySQL-python-1.2.4b5]# python setup.py build
[root@~MySQL-python-1.2.4b5]# python setup.py install然而神奇的事情发生了 ，竟然能用了
>>> import MySQLdb
>>> db = MySQLdb.connect("localhost","root","","test")
>>> cursor = db.cursor()
>>> cursor.execute("SELECT VERSION()")
>>> data = cursor.fetchone()
>>> print "Database version : %s"%data
Database version : 10.0.20-MariaDB
>>> db.close()成功了O(∩_∩)O哈！
