Python数据库创建-MySQL错误

Question

我一直在尝试使用 MySQL 模块在 python 中创建数据库。代码如下:

import MySQLdb
conn = MySQLdb.connect(host = '127.0.0.1', user='root', passwd='', db='test', port='3306')
cursor = conn.cursor()
cursor.execute("SELECT VERSION()")
row = cursor.fetchone()
print "server version:",row[0]
cursor.close()
conn.close()

我在与主机名相关的初始步骤中遇到了错误，我将主机名从 localhost 更改为本地 IP，并添加了一个端口关键字，该关键字似乎仅适用于引号。除此之外，我遇到以下错误:

Traceback (most recent call last):
  File "C:\Python27\server_version", line 4, in <module>
    conn = MySQLdb.connect(host = '127.0.0.1', user='root', passwd='', db='bhavin', port='3306')
  File "C:\Python27\lib\site-packages\MySQLdb\__init__.py", line 81, in Connect
    return Connection(*args, **kwargs)
  File "C:\Python27\lib\site-packages\MySQLdb\connections.py", line 187, in __init__
    super(Connection, self).__init__(*args, **kwargs2)
TypeError: an integer is required

Answer 1

port 应该是整数，而不是字符串:

conn = MySQLdb.connect(host='127.0.0.1', 
                       user='root', 
                       passwd='', 
                       db='test', 
                       port=3306)

不过，请注意 3306 是 default port如果未明确提供，则使用:

port

TCP port of MySQL server. Default: standard port (3306).
