HugeGraphServer Quick Start

1 概述

HugeGraph-Server 是 HugeGraph 项目的核心部分，包含Core、Backend、API等子模块。

Core模块是Tinkerpop接口的实现，Backend模块用于管理数据存储，目前支持的后端包括：Memory、Cassandra、ScyllaDB以及RocksDB，API模块提供HTTP Server，将Client的HTTP请求转化为对Core的调用。

文档中会大量出现HugeGraph-Server及HugeGraphServer这两种写法，其他组件也类似。这两种写法含义上并无大的差异，可以这么区分：HugeGraph-Server表示服务端相关组件代码，HugeGraphServer表示服务进程。

2 依赖

2.1 安装JDK-1.8

HugeGraph-Server 基于jdk-1.8开发，代码用到了较多jdk-1.8中的类和方法，请用户自行安装配置。

在往下阅读之前务必执行java -version命令查看jdk版本

java -version

2.2 安装GCC-4.3.0(GLIBCXX_3.4.10)或更新版本（可选）

如果使用的是RocksDB后端，请务必执行gcc --version命令查看gcc版本；若使用其他后端，则不需要。

gcc --version

版本对应关系

HugeGraphServer 部署安装

3 部署

有三种方式可以部署HugeGraph-Server组件：

方式1：一键部署
方式2：下载tar包
方式3：源码编译

3.1 一键部署

HugeGraph-Tools提供了一键部署的命令行工具，用户可以使用该工具快速地一键下载、解压、配置并启动HugeGraphServer和HugeGraphStudio。当然，还是得先下载HugeGraph-Tools的tar包。

wget https://github.com/hugegraph/hugegraph-tools/releases/download/v${version}/hugegraph-tools-${version}.tar.gz
tar -zxvf hugegraph-tools-${version}.tar.gz
cd hugegraph-tools-${version}

注：${version}为版本号，最新版本号可参考Download页面，或直接从Download页面点击链接下载

HugeGraph-Tools 的总入口脚本是bin/hugegraph，用户可以使用help子命令查看其用法，这里只介绍一键部署的命令。

bin/hugegraph deploy -v {hugegraph-version} -p {install-path} [-u {download-path-prefix}]

{hugegraph-version}表示要部署的HugeGraphServer及HugeGraphStudio的版本，用户可查看conf/version-mapping.yaml文件获取版本信息，{install-path}指定HugeGraphServer及HugeGraphStudio的安装目录，{download-path-prefix}可选，指定HugeGraphServer及HugeGraphStudio tar包的下载地址，不提供时使用默认下载地址，比如要启动 0.6 版本的HugeGraph-Server及HugeGraphStudio将上述命令写为bin/hugegraph deploy -v 0.6 -p services即可。

3.2 下载tar包

所有版本目录，我们这里使用 0.10.4 版本

https://github.com/hugegraph/hugegraph/releases

wget 
https://github.com/hugegraph/hugegraph/releases/download/v0.10.4/hugegraph-0.10.4.tar.gz
tar -zxvf hugegraph-0.10.4.tar.gz

3.3 源码编译

下载HugeGraph源代码

git clone https://github.com/hugegraph/hugegraph.git

编译打包生成tar包

cd hugegraph
mvn package -DskipTests

执行日志如下：

......
[INFO] Reactor Summary:
[INFO] 
[INFO] hugegraph .......................................... SUCCESS [  0.003 s]
[INFO] hugegraph-core ..................................... SUCCESS [ 15.335 s]
[INFO] hugegraph-api ...................................... SUCCESS [  0.829 s]
[INFO] hugegraph-cassandra ................................ SUCCESS [  1.095 s]
[INFO] hugegraph-scylladb ................................. SUCCESS [  0.313 s]
[INFO] hugegraph-rocksdb .................................. SUCCESS [  0.506 s]
[INFO] hugegraph-mysql .................................... SUCCESS [  0.412 s]
[INFO] hugegraph-palo ..................................... SUCCESS [  0.359 s]
[INFO] hugegraph-dist ..................................... SUCCESS [  7.470 s]
[INFO] hugegraph-example .................................. SUCCESS [  0.403 s]
[INFO] hugegraph-test ..................................... SUCCESS [  1.509 s]
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
......

执行成功后，在hugegraph目录下生成 hugegraph-*.tar.gz 文件，就是编译生成的tar包。

4 配置

如果需要快速启动HugeGraph仅用于测试，那么只需要进行少数几个配置项的修改即可（见下一节）。详细的配置介绍请参考配置文档及配置项介绍

5 启动

启动分为"首次启动"和"非首次启动"，这么区分是因为在第一次启动前需要初始化后端数据库，然后启动服务。而在人为停掉服务后，或者其他原因需要再次启动服务时，因为后端数据库是持久化存在的，直接启动服务即可。

HugeGraphServer启动时会连接后端存储并尝试检查后端存储版本号，如果未初始化后端或者后端已初始化但版本不匹配时（旧版本数据），HugeGraphServer会启动失败，并给出错误信息。

如果需要外部访问HugeGraphServer，请修改rest-server.properties的restserver.url配置项（默认为http://127.0.0.1:8080），修改成机器名或IP地址。

由于各种后端所需的配置（hugegraph.properties）及启动步骤略有不同，下面逐一对各后端的配置及启动做介绍。

HugeGraphServer的默认配置只能是本机访问，可以修改配置，使其能在其他机器访问。
 vim conf/rest-server.properties

 restserver.url=http://0.0.0.0:8080

5.1 Memory （建议测试学习时使用）

修改 hugegraph.properties

backend=memory
serializer=text

Memory后端的数据是保存在内存中无法持久化的，不需要初始化后端，这也是唯一一个不需要初始化的后端。

启动 server

bin/start-hugegraph.sh
Starting HugeGraphServer...
Connecting to HugeGraphServer (http://127.0.0.1:8080/graphs)....OK

提示的 url 与 rest-server.properties 中配置的 restserver.url 一致

5.2 HBase

用户需自行安装 HBase，要求版本 2.0 以上，下载地址

修改 hugegraph.properties

backend=hbase
serializer=hbase

# hbase backend config
hbase.hosts=localhost
hbase.port=2181

初始化数据库（仅第一次启动时需要）

cd hugegraph-${version}
bin/init-store.sh

查看日志，发现会在hbase创建一些表
