Hello Yipei,

 

You are on the track to debug this.

When you are logged into the amphora, please check the following logs to see what the amphora-agent error is:

 

/var/log/amphora-agent.log

And

/var/log/syslog

 

One of those two logs will have the error information.

Subject: [openstack-dev] [octavia] fail to plug vip to amphora

 

Hi, all,

 

I am trying to create a load balancer in octavia. The amphora can be booted successfully, and can be reached via icmp. However, octavia fails to plug vip to the amphora through the amphora client api and returns 500 status code, causing some errors as follows.

To fix the problem, I log in the amphora and find that there is one http server process is listening on port 9443, so I think the amphora api services is active. But do not know how to further investigate what error happens inside the amphora api service and solve it? Look forward to your valuable comments.

 

Best regards,

Yipei
