pymysql: 2003, "无法连接到 %r (%s) 上的 MySQL 服务器" % (self.host, e))

Question

使用 Python-2.7.6 并使用“easy_install-2.7”安装包“pymysql”和“MySQL-python” 我正在尝试从 python 脚本连接到远程 MySQL 服务器（客户端和 mysql 服务器都在同一个子网中）

脚本：

cluster_inbound_ip="10.0.xx.xx"
conn = pymysql.connect(host=cluster_inbound_ip, port=cluster_port, user=db_root_user, passwd=db_root_pass, db = db_name)

编译脚本后出错

  File "/root/test_case.py", line 41, in setup_module
    conn = pymysql.connect(host=cluster_inbound_ip, port=cluster_port, user=db_root_user, passwd=db_root_pass, db = db_name)
  File "/usr/local/lib/python2.7/site-packages/PyMySQL-0.6.1-py2.7.egg/pymysql/__init__.py", line 88, in Connect
    return Connection(*args, **kwargs)
  File "/usr/local/lib/python2.7/site-packages/PyMySQL-0.6.1-py2.7.egg/pymysql/connections.py", line 634, in __init__
    self._connect()
  File "/usr/local/lib/python2.7/site-packages/PyMySQL-0.6.1-py2.7.egg/pymysql/connections.py", line 818, in _connect
    2003, "Can't connect to MySQL server on %r (%s)" % (self.host, e))
OperationalError: (2003, "Can't connect to MySQL server on '10.0.xx.xx' (%d format: a number is required, not str)")

我能够 ping 以及能够从我的客户端从命令行连接到 MySQL 服务器。 此外，我验证了在 iptables 服务中添加 MySQL 和 HTTP 端口，如“Olaf Erlandsen”所建议的类似MySQLdb Issue

谁能建议或帮助解决这个问题？

我猜错误实际上来自这一行：

self.host_info = "socket %s:%d" % (self.host, self.port)

如果您将端口作为 str 而不是 int 传递，那么这就是您所期望的。

例如：

>>> print "socket %s:%d" % ("localhost", 8000)
socket localhost:8000
>>> print "socket %s:%d" % ("localhost", '8000')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: %d format: a number is required, not str
