django output wrong media url

Question

Django version is 1.10.3

Static file server is nginx

Debug mode off

The output media url has an absolute path in the server.

eg: http://127.0.0.1:8001/home/ken/hc/media/uploads/q/2017/03/01/hjqtye.png

The correct url is: http://127.0.0.1:8001/media/uploads/q/2017/03/01/hjqtye.png

How can i fix it? THX.

The relevant code as below.

settings.py

INSTALLED_APPS = [
    'grappelli',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'ckeditor',
    'ckeditor_uploader',
    'imagekit',
    'debug_toolbar',
    'gunicorn',
    'Website',
]

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'collected_static')
STATICFILES_DIRS = [(os.path.join(BASE_DIR, 'collected_static'))]
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'
CKEDITOR_UPLOAD_PATH = "uploads/"
#CKEDITOR_UPLOAD_PATH = os.path.join(BASE_DIR, MEDIA_ROOT, 'uploads')

Nginx conf file
