关于MySQL-python-1.2.3.tar.gz安装失败的解决方案

RHEL6.4升级到python2.7.9，然后安装 MySQL-python-1.2.3.tar.gz， 报错。解决错误之后，运行：

python2.7 -c "import MySQLdb"

失败：

>>> import MySQLdb

Traceback (most recent call last):

File "", line 1, in

File "/usr/local/lib/python2.7/site-packages/MySQL_python-1.2.3-py2.7-linux-x86_64.egg/MySQLdb/__init__.py", line 19, in

找了很多解决方法都无效。转而使用mysql官方的python连接器 mysql-connector-python。下载后安装：

# for mysql5.5+

$ wget 外链网址已屏蔽

# for mysql 4.1, 5.0, 5.1+

$ wget 外链网址已屏蔽

# or download from my ftp site:

$ wget ftp://pub:pub@$ wget ftp://pub:pub@

# install it:

$ tar zxf mysql-connector-python-1.2.0.tar.gz

$ cd mysql-connector-python-1.2.0

$ python2.7 setup.py build

$ sudo python2.7 setup.py install然后测试：import mysql.connector

>>> conn=mysql.connector.connect(user='root', password='******', host='127.0.0.1', database='devops')

Traceback (most recent call last):

raise errors.get_exception(packet)

mysql.connector.errors.DatabaseError: 1862 (HY000): Your password has expired. To log in you must change it using a client that supports expired passwords.

解决方法参考：

就是mysql密码过期，重设一下就OK:

mysql> show databases;

ERROR 1820 (HY000): You must SET PASSWORD before executing this statement

mysql> SET PASSWORD=PASSWORD('new pass here');

Query OK, 0 rows affected (0.00 sec)

然后再试：

>>> config={

... 'user':'root',

... 'password':'***********',

... 'host':'127.0.0.1',

... 'database':'devops',

... }

>>> conn = mysql.connector.connect(**config)

>>> cur = conn.cursor()

>>> q="SELECT * FROM packages"

>>> cur.execute(q)

>>> for row in cur:

... print row
