Installation 问：IBM云私有CE-致命：[9.29.100.159]=>；Etcd组件无法启动

在运行于ESXi5.5的Ubuntu 16.04.03虚拟机上首次安装ICP CE 2.1.0。虚拟机有4vCPU，16GB内存和170GB（我知道很小）。安装运行10分钟，但失败。我使用-vvv运行安装，但它并没有提供任何重要的见解

我如何解决这个问题？下一步可以/应该看哪里？

根据安装要求，如果您的单主机群集中运行所有管理服务，则至少需要8个核心CPU。如果您拥有的资源少于此数量，则可以禁用管理服务。计量和监控与config.yaml文件中禁用的_管理_服务一样：[“计量”、“监控”]。由于您有4个核心CPU，您可以在config.ymal中禁用这些服务，然后再次尝试安装。

我也遇到了同样的问题，Ubuntu 16.04上的ICP CE 2.1.0，KVM/OpenStack。相同消息：“Etcd组件启动失败”

当我在ICP机器上添加了允许从127.0.0.1访问端口4001的规则时，问题就消失了
