我不能索引我的數據庫索爾。我總是得到`索引失敗。回滾所有更改。

Question

我不能索引我的mysql數據庫與solr（4.0）。我總是得到Indexing failed. Rolled back all changes.我已經檢查了以前的答案，我無法弄清楚它是什麼問題。我在一個Docker（乘客phusion和ubuntu 14.04）容器中運行它。有任何想法嗎？我已經花了幾天的時間來弄清楚這一點。

<!-- AutoCommit 

    Perform a hard commit automatically under certain conditions. 
    Instead of enabling autoCommit, consider using "commitWithin" 
    when adding documents. 

    http://wiki.apache.org/solr/UpdateXmlMessages 

    maxDocs - Maximum number of documents to add since the last 
       commit before automatically triggering a new commit. 

    maxTime - Maximum amount of time in ms that is allowed to pass 
       since a document was added before automaticly 
       triggering a new commit. 
    openSearcher - if false, the commit causes recent index changes 
    to be flushed to stable storage, but does not cause a new 
    searcher to be opened to make those changes visible. 
    -->

</autoCommit> 

<!-- softAutoCommit is like autoCommit except it causes a 
    'soft' commit which only ensures that changes are visible 
    but does not ensure that data is synced to disk. This is 
    faster and more near-realtime friendly than a hard commit.

Answer 1

的問題是，我沒有連接到MySQL數據庫。 mysql數據庫主機錯誤。我明白了@MatsLindh。

在泊塢窗組成您services的名字是他們主機的名稱。所以，在我的情況下，mysql數據庫主機的名稱是db（請參閱docker在上面的問題中）。我的錯誤是我的環境變量中的mysql數據庫主機的名稱爲$ DB_HOST = localhost。

我意識到當我試圖從solr容器連接到mysql容器。我不得不這樣做

mysql --host=db --user=root --password= datacite 

因爲

mysql --host=localhost --user=root --password= datacite 

不能正常工作。

就是這樣。 在Docker撰寫過程中檢查數據庫主機的名稱。
