【问题描述】：
我在没有域（可通过 IP 地址访问）的 Ubuntu 16.04 VM 上关注 CKAN 2.8 的 official installation procedure from package。
我已经为/etc/ckan/default/ckan.ini 配置了VM 的HTTP URL (ckan.site_url = http://192.168.56.101:80)，但是当我调用ckan db init 时，它返回错误ckan.site_url is not configured and it must have a value。我还尝试了 URL 的其他变体，但它们都不起作用：
http://192.168.56.101http://192.168.56.101:80-
http://192.168.56.101/(the docs 说后面的斜杠不是必须的，但你永远不知道) "http://192.168.56.101"
我做错了什么？
你可以在下面看到/etc/ckan/default/ckan.ini的内容和ckan db init的输出。
daniele@ckantest:~$ cat /etc/ckan/default/ckan.ini
solr_url = http://127.0.0.1:8983/solr
ckan.site_id = ckan-demo
ckan.site_url = http://192.168.56.101:80
daniele@ckantest:~$ sudo ckan db init

编辑：
我添加了将ckan.demo 链接到192.168.56.101 的主机名规则，然后使用主机名编辑了ckan.ini，但错误仍然存在。显然错误不是由IP引起的，而是由其他原因引起的。
你可以在下面看到/etc/hosts的内容，/etc/ckan/default/ckan.ini的内容和ckan db init的输出。
daniele@ckantest:~$ cat /etc/hosts
