 	<h3 id="1-概述">1 概述</h3>
 <p>配置文件的目录为 hugegraph-release/conf，所有关于服务和图本身的配置都在此目录下。</p>
 <p>主要的配置文件包括：gremlin-server.yaml、rest-server.properties 和 hugegraph.properties</p>
 <p>HugeGraphServer 内部集成了 GremlinServer 和 RestServer，而 gremlin-server.yaml 和 rest-server.properties 就是用来配置这两个Server的。</p>
 <ul>
 <li><a href="http://tinkerpop.apache.org/docs/3.2.3/reference/#gremlin-server">GremlinServer</a>：GremlinServer接受用户的gremlin语句，解析后转而调用Core的代码。</li>
 <li>RestServer：提供RESTful API，根据不同的HTTP请求，调用对应的Core API，如果用户请求体是gremlin语句，则会转发给GremlinServer，实现对图数据的操作。</li>
 </ul>
 <p>下面对这三个配置文件逐一介绍。</p>
 <h3 id="2-gremlin-serveryaml">2 gremlin-server.yaml</h3>
 <p>gremlin-server.yaml 文件默认的内容如下：</p>

 <ul>
 <li>graphs：GremlinServer 启动时需要打开的图，该项是一个 map 结构，key 是图的名字，value 是该图的配置文件路径；</li>
 <li>channelizer：GremlinServer 与客户端有两种通信方式，分别是 WebSocket 和 HTTP（默认）。如果选择 WebSocket，
 用户可以通过 <a href="/clients/gremlin-console.html">Gremlin-Console</a> 快速体验 HugeGraph 的特性，但是不支持大规模数据导入，
 推荐使用 HTTP 的通信方式，HugeGraph 的外围组件都是基于 HTTP 实现的；</li>
 </ul>
 <p>默认GremlinServer是服务在 localhost:8182，如果需要修改，配置 host、port 即可</p>
 <ul>
 <li>host：部署 GremlinServer 机器的机器名或 IP，目前 HugeGraphServer 不支持分布式部署，且GremlinServer不直接暴露给用户;</li>
 <li>port：部署 GremlinServer 机器的端口；</li>
 </ul>
 <p>同时需要在 rest-server.properties 中增加对应的配置项 gremlinserver.url=http://host:port</p>
 <h3 id="3-rest-serverproperties">3 rest-server.properties</h3>
 <p>rest-server.properties 文件的默认内容如下：</p>
 <pre tabindex="0"><code class="language-properties" data-lang="properties"># bind url
 restserver.url=http://127.0.0.1:8080
 # gremlin server url, need to be consistent with host and port in gremlin-server.yaml
 #gremlinserver.url=http://127.0.0.1:8182

 # graphs list with pair NAME:CONF_PATH
 graphs=[hugegraph:conf/hugegraph.properties]

 # authentication
 #auth.authenticator=
 #auth.admin_token=
 #auth.user_tokens=[]

 server.id=server-1
 server.role=master
 </code></pre><ul>
 <li>restserver.url：RestServer 提供服务的 url，根据实际环境修改；</li>
 <li>graphs：RestServer 启动时也需要打开图，该项为 map 结构，key 是图的名字，value 是该图的配置文件路径；</li>
 </ul>
 <blockquote>
 <p>注意：gremlin-server.yaml 和 rest-server.properties 都包含 graphs 配置项，而 <code>init-store</code> 命令是根据 gremlin-server.yaml 的 graphs 下的图进行初始化的。</p>
 </blockquote>
 <blockquote>
 <p>配置项 gremlinserver.url 是 GremlinServer 为 RestServer 提供服务的 url，该配置项默认为 http://localhost:8182，如需修改，需要和 gremlin-server.yaml 中的 host 和 port 相匹配；</p>
 </blockquote>
 <h3 id="4-hugegraphproperties">4 hugegraph.properties</h3>
 <p>hugegraph.properties 是一类文件，因为如果系统存在多个图，则会有多个相似的文件。该文件用来配置与图存储和查询相关的参数，文件的默认内容如下：</p>

 </code></pre><p>重点关注未注释的几项：</p>
 <ul>
 <li>gremlin.graph：GremlinServer 的启动入口，用户不要修改此项；</li>
 <li>backend：使用的后端存储，可选值有 memory、cassandra、scylladb 和 rocksdb；</li>
 <li>serializer：主要为内部使用，用于将 schema、vertex 和 edge 序列化到后端，对应的可选值为 text、cassandra、scylladb 和 binary；(注：rocksdb后端值需是binary，其他后端backend与serializer值需保持一致，如hbase后端该值为hbase)</li>
 <li>store：图存储到后端使用的数据库名，在 cassandra 和 scylladb 中就是 keyspace 名，此项的值与 GremlinServer 和 RestServer 中的图名并无关系，但是出于直观考虑，建议仍然使用相同的名字；</li>
 <li>cassandra.host：backend 为 cassandra 或 scylladb 时此项才有意义，cassandra/scylladb 集群的 seeds；</li>
 <li>cassandra.port：backend 为 cassandra 或 scylladb 时此项才有意义，cassandra/scylladb 集群的 native port；</li>
 <li>rocksdb.data_path：backend 为 rocksdb 时此项才有意义，rocksdb 的数据目录</li>
 <li>rocksdb.wal_path：backend 为 rocksdb 时此项才有意义，rocksdb 的日志目录</li>
 <li>admin.token: 通过一个token来获取服务器的配置信息，例如：<a href="http://localhost:8080/graphs/hugegraph/conf?token=162f7848-0b6d-4faf-b557-3a0797869c55">http://localhost:8080/graphs/hugegraph/conf?token=162f7848-0b6d-4faf-b557-3a0797869c55</a></li>
 </ul>
 <h3 id="5-多图配置">5 多图配置</h3>
 <p>我们的系统是可以存在多个图的，并且各个图的后端可以不一样，比如图 hugegraph 和 hugegraph1，其中 hugegraph 以 cassandra 作为后端，hugegraph1 以 rocksdb作为后端。</p>
 <p>配置方法也很简单：</p>
 <p><strong>修改 gremlin-server.yaml</strong></p>
 <p>在 gremlin-server.yaml 的 graphs 域中添加一个键值对，键为图的名字，值为图的配置文件路径，比如：</p>
 <div class="highlight"><pre tabindex="0" style="background-color:#f8f8f8;-moz-tab-size:4;-o-tab-size:4;tab-size:4;"><code class="language-yaml" data-lang="yaml"><span style="display:flex;"><span><span style="color:#204a87;font-weight:bold">graphs</span><span style="color:#000;font-weight:bold">:</span><span style="color:#f8f8f8;text-decoration:underline"> </span>{<span style="color:#f8f8f8;text-decoration:underline">

 	<h3 id="概述">概述</h3>
 <p>HugeGraph 为了方便不同用户场景下的鉴权使用，目前内置了两套权限模式：</p>
 <ol>
 <li>简单的<code>ConfigAuthenticator</code>模式，通过本地配置文件存储用户名和密码 (仅支持单 GraphServer)</li>
 <li>完备的<code>StandardAuthenticator</code>模式，支持多用户认证、以及细粒度的权限访问控制，采用基于 “用户-用户组-操作-资源” 的 4 层设计，灵活控制用户角色与权限 (支持多 GraphServer)</li>
 </ol>
 <p>其中 <code>StandardAuthenticator</code> 模式的几个核心设计：</p>
 <ul>
 <li>初始化时创建超级管理员 (<code>admin</code>) 用户，后续通过超级管理员创建其它用户，新创建的用户被分配足够权限后，可以创建或管理更多的用户</li>
 <li>支持动态创建用户、用户组、资源，支持动态分配或取消权限</li>
 <li>用户可以属于一个或多个用户组，每个用户组可以拥有对任意个资源的操作权限，操作类型包括：读、写、删除、执行等种类</li>
 <li>&ldquo;资源&rdquo; 描述了图数据库中的数据，比如符合某一类条件的顶点，每一个资源包括 <code>type</code>、<code>label</code>、<code>properties</code>三个要素，共有 18 种类型、任意 label、任意 properties 可组合形成的资源，一个资源的内部条件是且关系，多个资源之间的条件是或关系</li>
 </ul>
 <p>举例说明：</p>

 <p>用户认证方式均采用 <a href="https://zh.wikipedia.org/wiki/HTTP%E5%9F%BA%E6%9C%AC%E8%AE%A4%E8%AF%81">HTTP Basic Authentication</a> ，简单说就是在发送 HTTP 请求时在 <code>Authentication</code> 设置选择 <code>Basic</code> 然后输入对应的用户名和密码，对应 HTTP 明文如下所示 :</p>
