Django ConnectionError（urllib3.connection.HTTPConnection）从Django管理员发布时

Question

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)

我得到这个连接错误，同时保存后从Django管理员。我有一个MYSQL数据库与设置

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

Answer 1

这是一个问题，因为我与haystack模块一起使用的elastic search安装不当。弹性搜索是使用Java构建的，至少需要Java8才能运行。一旦我安装了相同的，连接错误urlib3.connection.HTTPConnection就正常了。

Answer 2

我假设您的数据库是本地托管的

因此，请尝试在数据库的设置文件中更改此设置

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'mystic_db',
        'USER': 'root',
        'PASSWORD': '*****',
        'HOST': '127.0.0.1', or localhost whatever you prefer
        'PORT': '',
}
}
