Amazon ec2 Datastax Opscenter-代理未连接

我在EC2亚马逊机器上设置了Cassandra、OpsCenter和所需的DataStax代理。目前只有一台机器

除了节点列表为空以及Opscenter中的键空间为空之外，所有操作似乎都正常运行。cassandra、datastax和opscenter日志显示没有错误，我仔细地遵循了安装/配置。然后尝试了所有建议的修复方法

我猜问题在于代理和opscenter之间的通信

一段时间后，这些请求失败：

etc/cassandra/cassandra.yaml:（简化）

etc/opscenter/opscenterd.conf:（简化）

var/lib/datastax agent/conf/address.yaml:（简化）

nodetool状态输出：

除了agent.log中重复出现以下行之外，日志中没有显示任何奇怪的内容：

要在此处提供所有信息，请参阅以下日志：

在某些环境中，浏览器和opscenterd之间的持久连接可能会失败。我们正在致力于实现一种在所有环境下都能工作的更健壮的连接，但与此同时，您可以使用以下解决方法：

---

我发现工作的最低配置是在下面为address.yaml设置此选项

stomp_interface: [opscenter-ip]
stomp_port: 61620
use_ssl: 0
cassandra_conf: /etc/cassandra/cassandra.yaml
jmx_host: [cassandra-node-ip]
jmx_port: 7199

确保还安装了sysstat。

OpsCenter是否在代理后运行？不，不是在代理后运行。web接口在公共ip上侦听，而somp接口是私有ip。这不正确吗？这些/tcp故障几乎总是指向与反向代理相关的Web服务器配置。您能否提供访问OpsCenter的url（省略ip）？我认为stomp接口可以是一个私有IP，只要OpsCenter机器可以访问它。结果是AVG antivrus阻止了从浏览器到OpsCenter的传出流量。
