从Django admin发布Django ConnectionError（urllib3.connection.HTTPConnection）

错误信息：

Exception Type: ConnectionError at /admin/items/country/add/
Exception Value: ConnectionError (<urllib3.connection.HTTPConnection 
object at 0x111377110>: Failed to establish a new connection: [Errno 
61] Connection refused) caused by: 
NewConnectionError(<urllib3.connection.HTTPConnection object at 
0x111377110>: Failed to establish a new connection: [Errno 61] 
Connection refused)

我从Django管理员保存帖子时收到此连接错误 . 我有一个带设置的MYSQL数据库

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'mystic_db',
        'USER': 'root',
        'PASSWORD': '*****',
        'HOST': '',
        'PORT': '',

我是Django Python的新手 . 请求解决这个问题？
