我在 EC2 上托管的 64 位 Ubuntu 10.04 服务器 VM 上安装了 VCAP。我按照https://github.com/cloudfoundry/oss-docs/tree/master/vcap/single_and_multi_node_deployments_with_dev_setup中提到的步骤进行操作。请注意，这是一个单节点部署，所有 CloudFoundry 组件都部署在一个实例上。
我启动和停止了 VCAP，所有组件都按预期运行，包括 CloudController。
问题
我停止了 EC2 实例，然后再次启动它。然后我执行了启动 VCAP 的命令。但状态显示为 - CloudController 已停止，所有其他组件正在运行。
一些附加信息- 每当 EC2 实例重新启动时，其公共和私有 IP 都会更改。我做了一些谷歌搜索，并意识到 devsetup 脚本（参考https://github.com/cloudfoundry/oss-docs/tree/master/vcap/single_and_multi_node_deployments_with_dev_setup）在各个地方对 IP 进行了硬编码。因此，当我重新启动 EC2 实例时，IP 地址会更改并且 VCAP 不会启动。
我正在寻找一些关于如何更正缓存 IP 的信息？
谢谢， 安基特
在原始帖子中添加更多信息
EC2 实例重启后的原始 IP 10.142.81.107
新 IP 10.142.159.0
执行以下命令将 VCAP 指向新 IP：
cd ~/cloudfoundry/.deployments/devbox/config/
sed -i 's/10.142.81.107/10.142.159.0/g' *.yml
结果云控制器未启动。所有其他组件都启动了。
