2016-02-15 19:16:47 -0500 回答问题 How keystone and swift is making use of openssl ?

keystone can use ssl. You can modify keystone.conf to enable ssl.

 [ssl]
enable = True
certfile = /etc/keystone/ssl/certs/signing_cert.pem
keyfile = /etc/keystone/ssl/private/signing_key.pem
ca_certs = /etc/keystone/ssl/certs/ca.pem
ca_key = /etc/keystone/ssl/certs/cakey.pem
key_size = 1024
valid_days = 3650
ca_password = None
cert_required = False
cert_subject = /C=US/ST=Unset/L=Unset/O=Unset/CN=host.yoursite.org

In keystone,every token has an expire date,but it can not be set permanently. You can set the expire date to a longer time. The configuration of expire date is in keystone.conf:

#expiration=3600

Can you reinstall it?

2015-10-25 20:25:25 -0500 评论回答 failed to setup lbaas on kilo

No. Neutron-lbaas in kilo is an independent package which includes the plugins of lbaas. Neutron-lbaas-agent only includes agents of lbaas not plugins.

2015-10-22 01:22:09 -0500 回答问题 neutron agent-list error

From the error messages,the problem is your neutron version and your database are mismatch. The field load of agent table maybe added in kilo. Please check your release.

You must install openstack-neutron-lbaas on controller node.

ip link can only return lo and eth0. The IP of eth0 is the network A address. And the IP of lo is 127.0.0.1

I can only see the interface eth0 of network A on my instance. If I try to up the new interface eht1 on it, it returned an error: No such devdice. I used ifconfig to chenck interface and ifconfig eth1 up to up the new interface.

2015-09-28 04:08:29 -0500 问了问题 How to add an IP to a instance online?

After I launched a instance with network A, I want to add an IP of another network B to this instance. I have tried using these two commands to do above operation:

neutron port-create ------ to create a new port
nova interface-attach ------- to attach the new port to my instance

But after executing the two commands,I can not ping the new IP from other instances in network B. So,how can I do? And it must be completed online without stopping the instance.
