OrientGraph 无法创建到远程服务器的连接本地主机：2424

Question

问题

OrientGraph

Cannot create a connection to remote server localhost:2424

但 OrientDB 可以。 运行 Apache-TinkerPop-3 Gremlin 命令 通过 OrientDB API,
Java 或 Groovy.

Caused by: com.orientechnologies.orient.core.exception.OStorageException: Cannot create a connection to remote server address(es): [locahost:2424]

复制步骤

1. 已安装Docker
2. 下载了一个OrientDB Docker Image
3. 启动OrientDB容器
4. 创建了一个OrientDB数据库“demodb”
5. 已验证设置/运行
6. 创建了一个OrientGraph

   OrientGraph graph = OrientGraph.open("remote:locahost:2424/demodb","root","rootpwd");
   

7. 运行程序

import com.orientechnologies.orient.core.db.ODatabaseSession;
import com.orientechnologies.orient.core.db.OrientDB;
import com.orientechnologies.orient.core.db.OrientDBConfig;
import org.apache.tinkerpop.gremlin.orientdb.OrientGraph;

public class Main {

    public static void main(String[] args) {

        OrientDB orient = new OrientDB("remote:localhost:2424", OrientDBConfig.defaultConfig());
        ODatabaseSession db = orient.open("demodb", "root", "rootpwd");
        db.close();
        orient.close();

        OrientGraph graph = OrientGraph.open("remote:locahost:2424/demodb","root","rootpwd");
        graph.close();
    }
}

试过

1. 使用默认用户名/密码切换：admin/admin
2. 更改端口：

   2424

   改为

   2480

3. 删除数据库

   localhost:2424/demodb

   到

   localhost:2424

4. 检查OrientDB Gremlin Maven包
5. 检查 OrientDB 的 OrientGraph 格式

结果

期待

其中一个是我在设置和文档中遗漏或误解的内容。

实际

这些都没有改变输出异常错误。
