1.启动hugegraph服务

cd ~/hugegraph/hugegraph-0.12.0/
1

1.a 默认使用内置rocketmq数据库, 可修改为mysql

配置文件为: conf/graphs/hugegraph.properties

~/hugegraph/hugegraph-0.12.0/conf/graphs/hugegraph.properties

1.b 可修改web rest服务外部可访问:

#find ~/hugegraph/hugegraph-0.12.0/conf -type f  | xargs -I@ grep -Hn 127 @
sed -i "s/restserver.url=http:\/\/127.0.0.1:8080/restserver.url=http:\/\/0.0.0.0:8080/g" conf/rest-server.properties
#sed -i "g/restserver.url=http://127.0.0.1:8080/restserver.url=http://0.0.0.0:8080/s"  conf/rest-server.properties
#~/hugegraph/hugegraph-0.12.0/conf/rest-server.properties

1.c 可修改gremlin-server端口8182 监听任意ip

sed -i  "s/#host: 127.0.0.1/host: 0.0.0.0/" conf/gremlin-server.yaml
##~/hugegraph/hugegraph-0.12.0/conf/gremlin-server.yaml

注意 hugegraph的gremlin-server端口8182 理论上是可以被Tinerpop的gremlin-client : ‘org.apache.tinkerpop:gremlin-driver:3.6.1’ 正常连上的,
因为 gremlin-server确实是符合gremlin规范的服务 ， 但实际上 二者会有细微差异， 比如以下代码部分报错：

import org.apache.tinkerpop.gremlin.driver.remote.DriverRemoteConnection;
import org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversal;
import org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversalSource;
import org.apache.tinkerpop.gremlin.structure.Vertex;

import java.util.Map;

import static org.apache.tinkerpop.gremlin.process.traversal.AnonymousTraversalSource.traversal;

public class Test2 {
    public static void main(String[] args){
        GraphTraversalSource g = traversal().withRemote(DriverRemoteConnection.using("192.168.0.3",8182,"g"));
        GraphTraversal<Vertex, Map<Object, Object>> list = g.V().elementMap();
        test2(g);
        try {
            g.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    public static void test2(GraphTraversalSource g){
        Long vertexCnt = g.V().count().next();
        System.out.println("vertexCnt:"+vertexCnt);
    }
}

行"Long vertexCnt = g.V().count().next();"， 报错如下：

web界面创建图

注意 hubbleweb界面此时并不知道本机的hugegraph web服务8080端口的存在，所以要添加把本机服务添加到web界面上：
web点击创建图

hugegraph的client 语言支持貌似较弱(只有java client, 而且使用人数很少. 更没有官方py client) ，故而放弃hugegraph转向janusgraph
