2.3、部署Bosh时碰到的director通信错误
执行bosh deploy发布bosh任务的时候，执行到update director的时候，会因为与虚拟机的通信错误造成失败，错误显示如下：
Updating job director
director/0 (canary) (00:01:58)
Done 1/1 00:01:58
Error 400007: `director/0' is not running after update
Task 3 error
命令行执行bosh vms显示如下：
Deployment `bosh-openstack'
Director task 5
Task 5 done

可以看出director任务的状态是failing，连接到director的虚拟机上查看日志可以看到：

解决办法（命令行执行）：
monit stop director
monit start director
执行后没有任何反馈，稍等片刻后回到Bosh Cli的机器上查看虚拟机状态如下：
Deployment `bosh-openstack'

可以看出，director任务已经正常启动，此时，再重新部署下bosh即可正常，注意，不用删除原来的deployements，直接命令行执行bosh deploy即可。
