安裝MySQLdb后，import MySQLdb出錯(cuò)如下：
[root@lizhong MySQL-python-1.2.3]# /usr/local/bin/python2.7
Python 2.7.6 (default, Apr 10 2014, 15:45:39)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import MySQLdb
/usr/local/lib/python2.7/site-packages/MySQL_python-1.2.3-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-1.2.3-py2.7-linux-x86_64.egg/_mysql.pyc, but /soft/MySQL-python-1.2.3 is being added to sys.path
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "MySQLdb/__init__.py", line 19, in <module>
import _mysql

File "build/bdist.linux-x86_64/egg/_mysql.py", line 6, in __bootstrap__
ImportError: libmysqlclient.so.18: cannot open shared object file: No such file or directory
根據(jù)最后提示，應(yīng)該是找不著一個(gè)交libmysqlclient.so.18的文件，于是到mysql安裝目錄里找到這個(gè)文件并且做一個(gè)軟連接到/usr/lib
ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib/libmysqlclient.so.18
如果是64系統(tǒng)則：
ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib64/libmysqlclient.so.18
再次import MySQLdb就正常了：
[root@lizhong MySQL-python-1.2.3]# /usr/local/bin/python2.7
Python 2.7.6 (default, Apr 10 2014, 15:45:39)
