python解析数据包时出现问题_MySQL Connector / Python InterfaceError：“解析EOF数据包失败”...

据我所知，我已经安装了MySQL Connector / Python(v1.2.3)模块没有问题 . 这是在CentOS 5.4上使用Python 2.7.7(Anaconda发行版，尽管在vanilla安装上也是如此) . 我可以导入它并初始化与MySQL服务器的连接(v4.1.20) . 此服务器通过LAN访问，而不是本地访问 . is_connected() 方法断言我已正确连接

>>> import mysql.connector

>>> cnx = mysql.connector.connect()

>>> cursor = cnx.cursor()

>>> cnx.is_connected()

True

但是，每当我尝试直接通过游标命令(例如 cursor.execute("SELECT DATABASE();") )或间接通过mysql.connector方法(例如 get_database() )执行任何SQL查询时，我都会得到相同的错误，如下所示：

>>> cnx.get_database()

Traceback (most recent call last):

File "", line 1, in

File "/home/bgrande/software/genesis/anaconda-2.0.1/lib/python2.7/site-packages/mysql/connector/connection.py", line 1200, in get_database

eof = self._protocol.parse_eof(packet)

raise errors.InterfaceError(err_msg)

mysql.connector.errors.InterfaceError: Failed parsing EOF packet.

在此之后，似乎与MySQL服务器的连接丢失了 . 另一次运行 get_database() 的尝试返回以下错误：

>>> cnx.get_database()

Traceback (most recent call last):

File "", line 1, in

File "/home/bgrande/software/genesis/anaconda-2.0.1/lib/python2.7/site-packages/mysql/connector/connection.py", line 1200, in get_database

File "/home/bgrande/software/genesis/anaconda-2.0.1/lib/python2.7/site-packages/mysql/connector/connection.py", line 1433, in _info_query

cursor = self.cursor(buffered=True)

File "/home/bgrande/software/genesis/anaconda-2.0.1/lib/python2.7/site-packages/mysql/connector/connection.py", line 1328, in cursor

raise errors.OperationalError("MySQL Connection not available.")

mysql.connector.errors.OperationalError: MySQL Connection not available.

这由 is_connected() 方法确认 .

>>> cnx.is_connected()

False

另外，我应该提到在这个局域网上的另一台计算机上使用类似的设置(CentOS 5.5; Python 2.7.6)，我已成功使用MySQLdb模块与数据库进行交互 . 然而，与mysql.connector模块完全相同的Python安装不能(由于相同的错误) . 我试图在这里提到的第一台计算机上安装MySQLdb，但我遇到了问题 . 我认为MySQL Connector / Python可以更容易地工作 .

我担心这很难复制，因为它可能取决于我的具体环境 . 尽管如此，我还是希望能够采取措施缩小问题所在的范围 . 谢谢！
