Python中使用MySQL的问题

第一步：安装MySQL-python-1.2.2.tar

 

      python setup.py build 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 Downloading http://cheeseshop.python.org/packages/2.4/s/ setuptools/setuptools-0.6b1-py2.4.egg#md5=b79a8a403e4502fbb85ee3f1941735cb Processing setuptools-0.6b1-py2.4.egg creating /sw/lib/python2.4/site-packages/setuptools-0.6b1-py2.4.egg Extracting setuptools-0.6b1-py2.4.egg to /sw/lib/python2.4/site-packages Removing setuptools 0.6a11 from easy-install.pth file Adding setuptools 0.6b1 to easy-install.pth file Installing easy_install script to /sw/bin Installing easy_install-2.4 script to /sw/bin Installed /sw/lib/python2.4/site-packages/setuptools-0.6b1-py2.4.egg Processing dependencies for setuptools

   

    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

    MySQL-python-1.2.2]# vi setup_posix.py 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".
