我創建了兩個默認配置,羣集狀態節點:OrientDB - 如何在羣集服務器上創建數據庫?
"members": [{
"id": "192.168.1.101:2434",
"listeners": [{"protocol": "ONetworkProtocolBinary", "listen": "192.168.1.101:2424"}, {"protocol": "ONetworkProtocolHttpDb", "li
80"}],
"alias": "192.168.1.101:2434",
"status": "aligning"
}, {
"id": "192.168.1.102:2435",
"listeners": [{"protocol": "ONetworkProtocolBinary", "listen": "192.168.1.101:2425"}, {"protocol": "ONetworkProtocolHttpDb", "li
80"}],
"alias": "192.168.1.101:2435",
"status": "aligning"
}],
"name": "_hzInstance_1_orientdb",
"local": "192.168.1.101:2435"
}
,但是當我使用Java API連接到一臺服務器,並試圖建立一個數據庫,發生異常時,
admin = new OServerAdmin(PATH);
admin.connect("root", "password");
if (!admin.existsDatabase()) {
admin.createDatabase("document", "local");
}
堆棧:

爲什麼會發生這種情況?我如何在羣集服務器上創建數據庫?
THX。
感謝您的回答。所以我需要在本地機器上啓動服務器,創建數據庫,然後複製到201和204,然後重新啓動201,204。這些操作是否有任何文件? – niklaus
我們正在更新有關羣集上的新內容的文檔。但它只是目錄的一個副本。 – Lvca
聽起來像一個黑客,'distributed-config.json'已被複制。重新啓動我的雙節點羣集中的第二個節點後,其他數據庫文件會自動獲取。似乎只有最後一步沒有完全自動化。 – Dag
