Question

我已经运行DCHQ.io（On-Prem）几个月了，没有任何重大问题。

My Container Hosts环境如下所示：

DCHQ-VM-主机
RAM：14gb / CPU 4 / 100gb存储
10.21.38.165
host0 这是DCHQ所在的地方

多克尔-VM-1
RAM：8gb / CPU 2
10.21.36.201
主机1
托管LB容器的地方

多克尔-金属-2
RAM 96gb / CPU 12
10.21.39.71
主机2
托管APP容器的地方

多克尔 - 金属 - 4
RAM 96gb / CPU 12
10.21.38.170
主机4
托管数据库容器的地方

今天，在尝试为工作中的POC部署 3层Java（ApacheHTTP - Tomcat - MySQL）应用程序模板时，host-4已脱机。

几天前，我将host-1从BM计算机转换为VM。因此，我从DCHQ中删除了该主机，并使用相同的名称（host-1）将其添加回来，但这次是作为不同ESX服务器上的VM。不确定这是否与host-4有关，抛出下面的错误。因此，不能部署涉及host-4的模板，因此我将使用host-1和host-2进行部署。

我尝试重新启动主机-4，在DCHQ UI中停用/激活主机-4并在主机4上重新启动代理但无效。

我的最后一招是在主机4上删除并重新安装客户端，但我想先在此处发布。我也通过电子邮件发送DCHQ支持这个问题。

DCHQ日志显示以下错误：

感谢您报告此问题。请随时在我们的问题跟踪器上报告此事。 https://github.com/dchqinc/dchq-on-premise-issue-tracker/issues

请确保application.properties文件中的信息未更改。确保服务器密钥与DCHQ UI为host-4显示的内容相匹配。

   vi /opt/dchq/config/application.properties

然后您可以重新启动代理：

   service dchq stop
   ps -ef | grep dchq
   ## forcefully kill any DCHQ process that may not have stopped otherwise using kill -9
   service dchq start

最后 - 你能否从UI测试连接？这将有助于我们缩小问题范围。
