Python中使用MySQL的问题
第一步：安装MySQL-python-1.2.2.tar
python setup.py intstall
第二步：可能遇到的错误
1、libmysqlclient.so.16: cannot open shared object file: No such file or directory
需要安装新的包mysqlclient16-5.1.30-1.el5.remi.i386
或者通过ln -s设置链接
2、 在build的时候需要按照setuptools-0.6b1-py2.4.egg包
% wget -q http://peak.telecommunity.com/dist/ez_setup.py
% python ez_setup.py

这个按照需要上网，需要设置网络环境ip地址+DNS。
3 EnvironmentError: mysql_config not found
26 mysql_config.path = "/usr/local/mysql/bin/mysql_config"
将26行改为mysql_config的真是路径
再次执行python setup.py build;python setup.py install
就OK了
4 /usr/bin/ld: cannot find -lmysqlclient_r
解决方法一（已经测试通过）
执行以下命令：
echo “/usr/local/mysql/lib/mysql” >> /etc/ld.so.conf(我的环境是CentOS 5)
ldconfig，执行以后还是提示以上错误。
———————–
后来看来一下README,原文在下面
——————-
threadsafe
thread-safe client library (libmysqlclient_r) if True (default);
otherwise use non-thread-safe (libmysqlclient). You should
always use the thread-safe library if you have the option;
otherwise you *may* have problems.
———————————
得知得修改site.cfg,将thread-safe设为false,一切OK!
python setup.py install
解决方法二（没有测试）A thread-safe client library (libmysqlclient_r) will be created automatically during the compilation of MySQL if the configure command contains the option "--enable-thread-safe-client".
