| <p>为了验证 Ozone 正常运行,我们可以登录到 Datanode 并运行 Ozone 的负载生成工具 _freon_。 <code>exec datanode bash</code> 命令会在 Datanode 上启动一个 bash,<code>ozone freon</code> 命令在 Datanode 所在的容器内执行,你随时可以通过 CTRL-C 退出 freon,命令行选项 <code>rk</code> 会让 freon 生成随机的键。</p> |

| |
| <p>你可以通过 <a href="http://localhost:9874/">http://localhost:9874/</a> 访问 <strong>OzoneManager UI</strong> 来查看服务端处理 freon 负载的情况,以及浏览 ozone 的配置。</p> |

| <p><strong><em>恭喜,你成功运行了你的第一个 ozone 集群。</em></strong></p> |
