mysql-python的安装
安装过程遇到很多问题,备忘:
1、下载mysql-python
官网地址:http://sourceforge.net/projects/mysql-python/
#cd/usr/local
#wgethttp://nchc.dl.sourceforge.net/sourceforge/mysql-python/MySQL-python-1.2.2.tar.gz
2、解压
#tar-zxvfMySQL-python-1.2.2.tar.gz
#cdMySQL-python-1.2.2
3、在安装前要做下面几步
a、修改setup_posix.py中的mysql_config.path为你mysql安装目录的mysql_config路径
b、修改site.cfg中的threadsafe=False,mysql_config=/usr/local/mysql/bin/mysql_config
c、执行命令:(注意这个地方,三条命令都执行)
#exportLD_LIBRARY_PATH=/usr/local/mysql/lib/mysql
#ln-s/usr/local/mysql/lib/mysql/libmysqlclient.so/usr/lib/libmysqlclient.so.14
#ldconfig(这个重要)
否则后面会报错ImportError:libmysqlclient.so.14:cannotopensharedobjectfile
4、build和install
#pythonsetup.pybuild
#pythonsetup.pyinstall
5、使用
#python
#>>>importMySSQLdb
如果报错
/usr/lib/python2.3/site-packages/MySQL_python-1.2.2-py2.3-linux-i686.egg/_mysql.py:3:UserWarning:Module_mysqlwasalreadyimportedfrom/usr/lib/python2.3/site-packages/MySQL_python-1.2.2-py2.3-linux-i686.egg/_mysql.pyc,but/usr/local/src/MySQL-python-1.2.2isbeingaddedtosys.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python就可以了。
