我正在尝试通过python中的pymysql包连接mysql：
>>> import pymysql
>>> conn = pymysql.connect(host='10.1.1.216',port=3306, user='linxz_genome', password='linxz123', database='linxz_genome')
工作正常。但是在烧瓶中它会引发一个错误：

OperationalError: (OperationalError) (1045, u"Access denied for user 'linxz_genome'@'10.1.1.223' (using password: YES)") None None
从错误消息中，我发现IP 10.1.1.215与python代码中的10.1.1.216不同。 config.py位于以下位置：
class ProductionConfig(Config):
dbuser = 'linxz_genome'
dbname = 'linxz_genome'
dbhost = '10.1.1.216:3306'
dbpass = 'linxz_glean20161026'
SQLALCHEMY_DATABASE_URI = 'mysql+pymysql://' + \
dbuser + ':' + dbpass + '@' + dbhost + \
'/' + dbname + '?charset=utf8mb4'
SQLALCHEMY_COMMIT_ON_TEARDOWN = True
我找到了一些关于此错误的threads并尝试了以下命令：
mysql> GRANT ALL on *.* to 'linxz_genome'@'10.1.1.216' IDENTIFIED BY 'linxz123' WITH GRANT OPTION;
ERROR 1045 (28000): Access denied for user 'linxz_genome'@'%' (using password: YES)
如何在flsak中修复此错误？
