apache atlas 服务器的连接被拒绝

Connection refused for apache atlas server

我在 EC2 上安装了 apache atlas。设置后,我使用命令 python2 atlas_start.py 启动了 apache atlas,它成功启动了以下日志:

configured for local hbase.
hbase started.
configured for local solr.
solr started.
setting up solr collections...
starting atlas on host localhost
starting atlas on port 21000
..............................................................................................................................................................................................................................................................................................................
Apache Atlas Server started!!!

但是,当我尝试访问服务器 URL 以验证 apache atlas 是否已启动并且 运行。它给了我连接被拒绝的错误。下面是我用来访问服务器的命令: curl -u username:password http://localhost:21000/api/atlas/admin/version

此外,在设置时它没有要求我输入用户名和密码,所以我使用 admin:admin 作为用户名密码。

原因有很多 - 请进行以下检查

  1. 请根据您的设置方式检查 logs 目录中的日志。 (如果你只是 运行 它通过 mvn)

  2. 您需要 hbase(至少)和 solr/elastic/cassandra(atlas 后端)。检查您是否处于 运行 嵌入式模式 - atlas 将在其中启动自己的后端。它通常设置为环境变量。即:MANAGE_LOCAL_HBASE

  3. 确保atlas-application.properties在启动前配置正确。

    希望对您有所帮助!

编辑: 我注意到你提到了 ec2。确保您配置了正确的安全组。

您必须使用“mvn clean install -Pdist”构建服务器,完成后您需要导航至 distro/target/ 文件夹,然后 运行 atlas_start.py 从那里开始。

此脚本的问题是使用 atlas_start.py 启动图集大约需要 10 分钟。虽然其过程未完成,但您面临 connection refused 错误。

为了查看是否完成,您可以使用tail -n 10 application.logcat application.log检查logs目录中的application.log文件。 2.1.0版本application.log最后10行如下:

之后就可以看到登录页面http://localhost:21000

或使用 curl 命令:

~ ➤ curl -u admin:admin http://localhost:21000/api/atlas/admin/version
