+Ozone 支持与 HDFS 并存工作，所以在已有的 HDFS 集群上部署 Ozone 比较容易。
+
+Ozone 的容器管理组件可以在 HDFS 数据节点上运行，以插件的形式或是独立运行，下文介绍插件运行的方法。
+
+为了启用 Ozone，你需要定义服务插件实现类。
+
+<div class="alert alert-warning" role="alert">
+<b>重要</b>：因为插件在 HDFS 数据节点启动过程中被激活，服务插件实现类的定义需要添加到 <b>hdfs-site.xml</b> 中。
+</div>
+
+{{< highlight xml >}}
+<property>
+   <name>dfs.datanode.plugins</name>
+   <value>org.apache.hadoop.ozone.HddsDatanodeService</value>
+</property>
+{{< /highlight >}}
+
+此外还需要将 /opt/ozone/share/ozone/lib/ 路径下的 jar 包添加到 classpath 下： 
+
+{{< highlight bash >}}
+export HADOOP_CLASSPATH=/opt/ozone/share/ozone/lib/*.jar
+{{< /highlight >}}
+
+
+
+让 ozone 随 HDFS 一同启动的步骤为：
+
+ 1. HDFS Namenode（从 Hadoop 中启动）
+ 2. HDFS Datanode (从 Hadoop 中启动，需要按照如上配置插件和 classpath）
+ 3. Ozone Manager (从 Ozone 中启动）
+ 4. Storage Container Manager (从 Ozone 启动）
+
+检查数据节点的日志以确认 HDDS/Ozone 插件是否启动，日志中应当包含以下内容：
+
+```
+2018-09-17 16:19:24 INFO  HddsDatanodeService:158 - Started plug-in org.apache.hadoop.ozone.web.OzoneHddsDatanodeService@6f94fb9d
+```
+
+<div class="alert alert-warning" role="alert">
+<b>注意：</b> 当前版本的 Ozone 使用 Hadoop 3.1 使用测试。
