MySQL-Python安装问题小记
安装完mysql-python后import加载模块提示以下错误，
ImportError: libmysqlclient_r.so.16: cannot open shared object file: No such file or directory
于是google之，总结一下解决方法：
（1）在mysql-ython的安装目录下找到site.cfg，将
#mysql_config = XXXXXXXXXXXXXXXX
注释符号去掉，并填上mysql_config的地址
（2）将mysql/lib下所有关于libmysqlclient的so文件软链接到/usr/lib下。
ln -s /usr/local/mysql/lib/mysql/libmysqlclient* /usr/lib ldconfig
这样在加载
import _mysql
的时候就不会出错了
ubuntu 安装mysql-python遇到的问题
版本是python 2.6
使用easy_install 安装MySQL-python
easy_install "MySQL-python==1.2.3"
提示：error: Setup script exited with error: command 'gcc' failed with exit status 1
需要安装 python-devel
sudo apt-get install python-dev
#apt-get install python-devel
再使用easy_install 安装就可以
如果使用python setup.py 安装，提示mysql_config找不到
EnvironmentError: mysql_config not found
需要安装下面2个开发包，需要注意的是apt-get里面是没有的，我使用新立德软件包管理器安装
libmysqld-dev
libmysqlclient-dev
安装完成以后需要修改MySQL-python-1.2.3文件夹下面的setup_posix.py中的第26行,
mysql_config.path = "mysql_config"改为mysql_config的路径
whereis mysql_config查找路径
mysql_config.path = "/usr/bin/mysql_config"
再使用
python setup.py build
python setup.py install
就可以
ubuntu root 权限
sudo -i
安装MySQL-python问题解决
今天在centos安装MySQL-python，结果报错，报错信息如下：

google找到答案（http://stackoverflow.com/questions/13044201/install-mysql-python-return-error-in-centos），需要先安装mysql-devel.x86_64，通过
sudo yum install mysql-devel.x86_64
再次安装成功
