[huangpeilong]

Expected behavior

1. git clone https://github.com/Dataman-Cloud/crane.git
2. cd /release/v1.0.6
   3.CRANE_IP=X.X.X.X VERSION=v1.0.6 ./deploy.sh
3. Start the crane and use it to manage containers

Actual behavior

1.2.3 setps are the same
4. The crain starts with no error, but cann't log into the crane, the browser reports 502

Information about the Issue

1. Crane report "Service busy, please try again later" while logging in the crane
2. After analyse the log of containers, it seems the env does not work

Steps to reproduce the behavior

The following setps are passed on the Vmware machine with Ubuntu14.04, but error occurs when deploying crane on the Ubuntu16.04 real machine

1. 2. 3. steps are the same as expected behavior.
