安装mysqldb后，import mysqldb出错如下：

复制代码 代码如下:

[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

importerror: libmysqlclient.so.18: cannot open shared object file: no such file or directory

根据最后提示，应该是找不着一个交libmysqlclient.so.18的文件，于是到mysql安装目录里找到这个文件并且做一个软连接到/usr/lib
复制代码 代码如下:

ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib/libmysqlclient.so.18

如果是64系统则：
复制代码 代码如下:

ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib64/libmysqlclient.so.18

再次import mysqldb就正常了：
复制代码 代码如下:

[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
>>>
