Centos环境下MySQL-python安装过程

1. 下载 MySQL-python-1.2.3.tar.gz
    地址 https://sourceforge.net/projects/mysql-python/

2. 安装 MySQl-python
    tar xvf MySQL-python-1.2.3.tar.gz
    cd MySQL-python-1.2.3
    vi site.cfg
    把 mysql_config = /usr/local/mysql/bin/mysql_config 这一行前的#去掉，并且把mysql_config的路径设置正确。
    python setup.py build
    运行上面的命令报错如下：

[root@localhost MySQL-python-1.2.3]# python setup.py  install Traceback (most recent call last):   File "setup.py", line 5, in ?     from setuptools import setup, Extension ImportError: No module named setuptools

解决方法：

wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz tar zxvf setuptools-0.6c11.tar.gz cd setuptools-0.6c11 python setup.py build python setup.py install

出现错误

_mysql.c:36:23: 错误：my_config.h：没有那个文件或目录
_mysql.c:38:19: 错误：mysql.h：没有那个文件或目录
_mysql.c:39:26: 错误：mysqld_error.h：没有那个文件或目录
_mysql.c:40:20: 错误：errmsg.h：没有那个文件或目录

设置include 头文件路径

export C_INCLUDE_PATH=/usr/local/mysql/include/mysql

继续安装：

python setup.py build python setup.py install

运行测试：

[root@localhost MySQL-python-1.2.3]# python Python 2.4.3 (#1, Sep  3 2009, 15:37:37)  [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import MySQLdb /usr/lib64/python2.4/site-packages/MySQL_python-1.2.3-py2.4-linux-x86_64.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /usr/lib64/python2.4/site-packages/MySQL_python-1.2.3-py2.4-linux-x86_64.egg/_mysql.pyc, but /opt/python/MySQL-python-1.2.3 is being added to sys.path >>>

报出一大堆警告信息，解决办法：删除MySQL-python源目录，再测试一下：

[root@localhost python]# python Python 2.4.3 (#1, Sep  3 2009, 15:37:37)  [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import MySQLdb >>>

Mysql模块终于正常了！

报错：

ImportError: libmysqlclient_r.so.16: cannot open shared object file: No such file or directory

1.确定libmysqlclient_r.so.16的位置

/usr/local/mysql/lib/mysql/libmysqlclient_r.so.16 -> libmysqlclient_r.so.16.0.0

2.确定libmysqlclient_r.so.16使用的函数库及其位置

ldd  /usr/local/mysql/lib/mysql/libmysqlclient_r.so.16

/usr/local/mysql/lib/mysql/libmysqlclient_r.so.16.0.0

ldd -v   /usr/local/mysql/lib/mysql/libmysqlclient_r.so.16

/lib64

3.拷贝函数库到需要位置

cp -af  /usr/local/mysql/lib/mysql/libmysqlclient_r.so.16.0.0   /lib64
或者 vim /etc/ld.so.conf将/usr/local/mysql/lib/mysql该目录添加到第一行

4.ldconfig

5.ldconfig -v | grep  libmysqlclient_r.so.16

import MySQLdb sucess!!!!
