问题1：VMC无法登陆
问题描述如下：大致情况就是，我可以注册，但是在登陆过程中出现了404错误。
root@arch3:~/cloudfoundry/vcap/dev_setup/bin# vmc target api.vcap.me
Successfully targeted to []
root@arch3:~/cloudfoundry/vcap/dev_setup/bin# vmc register
Email: y...@...com
Password: ***
Verify Password: ***
Creating New User: OK
Attempting login to []
Problem with login to 'http://api.vcap.me', 404: entity not found or
inaccessible, try again or register for an account.
解决方法：这个问题我找到的答案就是-将vmc重0.3.21版本降级到0.3.18版本，为什么会这样，我就不明白了。
问题2：部署的应用无法启动：
问题描述如下：这个是从网上copy下来的，当时情况是我执行vmc push hello，然后在Staging Application的时候出现了下面的这个错误。
root@Ubuntu:/home/cloudfoundry# vmc start hello
Staging Application: .............Error (JSON 504):<html><head><title>504 Gatewa...
root@ubuntu:/home/cloudfoundry# vmc update hello
Uploading Application:
Checking for available resources: ok
Processing resources: ok
Packing application: ok
Uploading (706K): ok
Error (JSON 504):<html>
<head><title>504 Gatewa...
解决方法：这个东西我在网上没有找到答案，然后我们返回看我们开始部署的时候是怎么写的配置文件：
---
deployment:
name: "rest"
jobs:
install:
- nats_server
- cloud_controller:
builtin_services:
- redis
- mongodb
- mysql
- router
- health_manager
- ccdb
- redis_node:
index: "0"
- redis_gateway
- mysql_gateway
- mongodb_node:
index: "0"
- mongodb_gateway
问题就是在于，新的CF已经将stager（打包）这个功能从原有的Cloud Controller中剥离开了。
所以我们需要做的事情就很简单了，重新装一次rest，只是这次记得将stager给添加上就可以了。
vm@vm:~/test$ vim /home/vm/cloudfoundry/vcap/dev_setup/deployments/sample/multihos
t_mysql/rest.yml
---
deployment:
name: "rest"
jobs:
install:
- nats_server
- cloud_controller:
builtin_services:
- redis
- mongodb
- mysql
- router
- stager
- health_manager
- ccdb
- redis_node:
index: "0"
- redis_gateway
- mysql_gateway
- mongodb_node:
index: "0"
- mongodb_gateway
然后再试试看
vm@vm:~/cloudfoundry/vcap/dev_setup$ vmc start hello
Staging Application 'hello': OK
