DataStax Enterprise版本4.0.2，Cassandra 2.0.6和Opscenter 4.1.2。 show＆＃34;创建集群时出错：添加集群时超时＆＃34;

时间：2014-05-13 11:25:43

标签： datastax opscenter

我在Amazon EC2上设置了具有5个节点的群集，具有多个区域中心。 ops中心节点/实例与群集节点分开。 当我尝试通过opscenter Web添加现有群集时，它会显示＆＃34;创建群集时出错：添加群集时超时。请查看日志以获取有关问题的详细信息。＆＃34; 在网上。然后我检查了opscenterd.log，似乎opscenter可以连接两个节点，但是一个警告：＆＃34;在调用CreateClusterConfController时处理错误：添加集群时超时。请查看日志以获取有关问题的详细信息。＆＃34;

你对这个问题有什么想法吗？我使用的是DataStax Enterprise 4.0.2版，Cassandra 2.0.6和Opscenter 4.1.2。我在Ubuntu 12.0.4上创建集群 我检查了Cassandra系统日志和datastax-agent代理日志，但没有错误。

这是否存在任何问题？喜欢opscenter版本4.1.0问题＆＃34;使用Python 2.6和＃34;在平台上更新定义文件时，opscenterd崩溃;这已在4.1.1中修复。 http://www.datastax.com/documentation/opscenter/4.1/opsc/release_notes/opscReleaseNotes411.html

请建议。

我在两个日志中都看不到任何错误，但仍然认为节点正在连接，但我仍然遇到超时错误

任何人都可以帮助我。

2 个答案:

答案 0 :(得分：4)

有几件事可能导致超时，其中一些是Cassandra中的错误，其中一些可以优化OpsCenter端。您可以通过在/ etc / opscenter / clusters /中手动创建集群配置文件并重新启动opscenterd来解决此问题。例如，将以下内容写入mycluster.conf：

[cassandra]
seed_hosts = 1.2.3.4, 2.3.4.5

对于该群集正常工作可能仍需要约1分钟，但这将绕过超时检查。

答案 1 :(得分：0)

自opscenter与群集节点分离以来最可能出现的问题是防火墙问题（安全组）

查看此处列出的端口http://www.datastax.com/documentation/datastax_enterprise/4.0/datastax_enterprise/sec/secConfFirePort.html，并确保您可以从opscenterd telnet到群集节点，然后再返回相关端口。

您提到的错误会导致错误，堆栈跟踪将包含ERROR：错误更新定义文件
