python2.7安装MySQLdb

1.下载MySQL-python

http://sourceforge.net/projects/mysql-python/files/mysql-python-test/1.2.3b1/MySQL-python-1.2.3b1.tar.gz/download

tar -zxf MySQL-python-1.2.3b1.tar.gz
cd MySQL-python-1.2.3b1
python setup.py build

==>ImportError: No module named setuptools

2.下载setuptools

http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c8.tar.gz

tar -zxf setuptools-0.6c8.tar.gz
cd setuptools-0.6c8
python setup.py build
python setup.py install

3.回到MySQL-python-1.2.3b目录

cd MySQL-python-1.2.3b1

在运行时python setup.py build && python setup.py install没有如下错误:

有类似错误，处理方式如下:

python setup.py build

#若,报错:mysql_config not found

找出mysql 安装目录如:/opt/mysql/

vim MySQL-python-1.2.3b1/setup_posix.py

'''行26'''      mysql_config.path = "mysql_config"

改成如下:

'''行27'''     mysql_config.path = "/opt/mysql/bin/mysql_config"

2.MySQLdb ImportError: libmysqlclient.so.18解决方法

ImportError: libmysqlclient.so.18: cannot open shared object file: No such file or directory

根据最后提示，应该是找不着一个交libmysqlclient.so.18的文件，于是到mysql安装目录里找到这个文件并且做一个软连接到/usr/lib

如果找不到 可以执行如下命令，找到MySQL安装目录的该文件：

find / -name libmysqlclient.so.18

然后创建软连接

本地so.18路径 > /usr/lib/libmysqlclient.so.18

32位：

ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib/libmysqlclient.so.18

64位：

ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib64/libmysqlclient.so.18

3.import MySQLdb UserWarning错误

>>>import MySQLdb
/usr/local/lib/python2.7/site-packages/MySQL_python-1.2.3b1-py2.7-linux-x86_64.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /usr/local/lib/python2.7/site-packages/MySQL_python-1.2.3b1-py2.7-linux-x86_64.egg/_mysql.pyc, but /data/tools/MySQL-python-1.2.3b1 is being added to sys.path

原因是，install后MySQLdb模块已经被放到python的site-pachages目录中；但我在当前目录也存在相同的模块，所以可能会重复导入。只要切换到其他目录运行就可以了。
