    这个是设置:

    DATABASES = {
    'default': {
    'ENGINE': 'django.db.backends.postgresql_psycopg2',
    'NAME': 'spider',
    'USER': 'root',
    'PASSWORD': 'root',
    'HOST': '127.0.0.1',
    'PORT': '5432',
    'CONN_MAX_AGE': 60,
    }
    }

    CONN_MAX_AGE 是指 idle 了60秒的连接会被reaper收走。你如果59秒一次操作59秒一次操作,就会永远长连。
