2014-01-15 02:48:12 -0500 问了问题 Problem on setting up Ceilometer

Hi

I am trying to install and configured ceilometer in my env.

I have added openstack-ceilometer-api, openstack-ceilometer-central and openstack-ceilometer-collector on controller node, and added openstack-ceilometer-compute on compute node.

But there is no output when executing "ceilometer meter-list" on controller node. Any idea?

I checked on the log on both controller and compute nodes, and only able to find the error in /var/log/ceilometer on compute node. But I am not sure how to resolve. probably there is some config problem in /etc/ceilometer/ceilomter.conf.

2014-01-15 16:46:13.934 26780 ERROR ceilometer.openstack.common.rpc.impl_qpid [-] Unable to connect to AMQP server: [Errno 111] ECONNREFUSED. Sleeping 60 seconds

2014-01-08 03:59:19 -0500 回答问题 Problem on using "neutron router-gateway-set"

Hi

I would like to double check the concepts on configuring Neutron.

I created external network named "ext-net" with below id

[root@network01 ~]# neutron net-list +--------------------------------------+----------+--------------------------------------------------+ | id | name | subnets | +--------------------------------------+----------+--------------------------------------------------+ | b6d746f0-c029-4ae7-89ac-606b84f5162e | ext-net | 69d3e3ee-1b2e-4405-9ead-9527581eee2a 10.0.0.0/24 | +--------------------------------------+----------+--------------------------------------------------+

Also ,created router "ext_to_int" with below id [root@network01 ~]# neutron router-list +--------------------------------------+------------+-----------------------+ | id | name | external_gateway_info | +--------------------------------------+------------+-----------------------+ | 59477cf6-669f-402a-ae0e-a92ba9233b39 | ext-to-int | null | +--------------------------------------+------------+-----------------------+

Also, created internal network named "demo-net with below id +--------------------------------------+----------+--------------------------------------------------+ | id | name | subnets | +--------------------------------------+----------+--------------------------------------------------+ | 027d2aa9-35f2-41bd-87b3-b618b6287449 | demo-net | f53237f4-7897-47c0-a5dc-f74562870281 10.5.5.0/24 |

So, I should execute below commands, am I correct?

[root@network01 ~]# neutron router-gateway-set 59477cf6-669f-402a-ae0e-a92ba9233b39 b6d746f0-c029-4ae7-89ac-606b84f5162e Set gateway for router 59477cf6-669f-402a-ae0e-a92ba9233b39

[root@network01 ~]# neutron router-interface-add 59477cf6-669f-402a-ae0e-a92ba9233b39 f53237f4-7897-47c0-a5dc-f74562870281
Added interface bbb796ff-0a41-4fe6-8412-3df9325cfbb6 to router 59477cf6-669f-402a-ae0e-a92ba9233b39.

Is it correct? If yes, what next?

Hi

I faced a problem while executing "neutron router-gateway-set" command.

[root@network01 ~]# neutron router-gateway-set 100 101 Unable to find router with name '100'

I have checked the /etc/neutron/l3_agent.ini, and it should be defined. any idea?

router_id = 100 gateway_external_network_id = 101ni, and

Hi

I have setup three nodes to run for Neutron networking, controller node, network node, and compute node. After following chapter 9 in OPENSTACK INSTALLATION GUIDE FOR RED HAT ENTERPRISE LINUX, CENTOS, AND FEDORA - HAVANA to setup all three nodes, I started on configuring the system based on " Create the base Neutron networks".

When I run below command, I got the error as below.

[root@network01 ~]# neutron net-create ext-net -- --router:external=True --provider:network_type gre --provider:segmentation_id 2 400-{u'NeutronError': {u'message': u'Invalid input for operation: gre networks are not enabled.', u'type': u'InvalidInput', u'detail': u''}}

any idea

Hi

The keystone should be located in the controller (controller02)

2014-01-06 04:08:29 -0500 问了问题 Neutron net-create requires that tenant_id is specified

I am setting up OpenStack using Neutron networking services, and I am following the setup guides to define three nodes, one is controller, one is network and one is compute.

WHen I try to run below command in network node, I got below error.

[root@network01]# neutron net-create ext-net -- --router:external=True --provider:network_type gre --provider:segmentation_id 2
Running without keystone AuthN requires  that tenant_id is specified

I have checked the /etc/neutron/neutron.conf, and the auth_strategy is set to keystone.

I also check the agent-list, it shown below.

[root@network01 neutron]# neutron agent-list

Thank for the hints. I found that the services are down due to changing of hostname. is there anyway to update the hostname without affecting the services?
