我不能用索尔索引我的数据库。 我总是得到`索引失败。 回滚所有的变化
我不能索引我的mysql数据库与solr（4.0）。 我总是Indexing failed. Rolled back all changes. Indexing failed. Rolled back all changes. 我已经回顾以前的答案，我无法弄清楚是什么问题。 我在Docker（passenger phusion和ubuntu 14.04）容器中运行它。 有任何想法吗？ 我已经花了几天的时间来弄清楚这一点。

<!-- AutoCommit Perform a hard commit automatically under certain conditions.

问题是我没有连接到MySQL数据库。 MySQL数据库主机是错误的 。 我明白了，感谢@MatsLindh。
在docker撰写你的services的名称是他们的主机的名称。 所以，在我的情况下，MySQL数据库主机的名称是db （请参阅docker在上面的问题）。 我的错误是，我有一个环境variables中的MySQL数据库主机的名称$ DB_HOST = localhost。
我意识到，当我试图从solr容器连接到MySQL容器。 我必须做
mysql --host=db --user=root --password= datacite
因为
mysql --host=localhost --user=root --password= datacite
不工作。
就是这样了。 在docker撰写时，检查数据库主机的名字。
