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 "<stdin>", line 1, in <module>
  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 <module>
  File "/usr/local/lib/python2.7/site-packages/MySQL_python-1.2.3-py2.7-linux-x86_64.egg/_mysql.py", line 7, in <module>
  File "/usr/local/lib/python2.7/site-packages/MySQL_python-1.2.3-py2.7-linux-x86_64.egg/_mysql.py", line 6, in __bootstrap__

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 http://ftp.ntu.edu.tw/MySQL/Downloads/Connector-Python/mysql-connector-python-2.1.1.tar.gz

# for mysql 4.1, 5.0, 5.1+
$ wget http://ftp.ntu.edu.tw/MySQL/Downloads/Connector-Python/mysql-connector-python-1.2.0.tar.gz

# or download from my ftp site:

$ wget ftp://pub:pub@pepstack.com/tarball/mysql-connector-python-1.2.0.tar.gz

$ wget ftp://pub:pub@pepstack.com/tarball/mysql-connector-python-2.1.1.tar.gz

# 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):
  File "<stdin>", line 2, in <module>
  File "/usr/local/lib/python2.7/site-packages/mysql/connector/__init__.py", line 176, in connect
    return MySQLConnection(*args, **kwargs)
  File "/usr/local/lib/python2.7/site-packages/mysql/connector/connection.py", line 95, in __init__
    self.connect(**kwargs)
  File "/usr/local/lib/python2.7/site-packages/mysql/connector/abstracts.py", line 719, in connect
    self._open_connection()
  File "/usr/local/lib/python2.7/site-packages/mysql/connector/connection.py", line 213, in _open_connection
    self._ssl)
  File "/usr/local/lib/python2.7/site-packages/mysql/connector/connection.py", line 144, in _do_auth
    self._auth_switch_request(username, password)
  File "/usr/local/lib/python2.7/site-packages/mysql/connector/connection.py", line 180, in _auth_switch_request
    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:

https://dev.mysql.com/doc/refman/5.6/en/password-expiration-sandbox-mode.html

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
