《转》Ubuntu14.04 openstack juno配置之 ceilometer遥测模块安装配置 / 憋错料

（一）在控制节点上

1.安装的遥测服务

apt-get install -y ceilometer-api ceilometer-collector ceilometer-agent-central

ceilometer-agent-notification ceilometer-alarm-evaluator \

ceilometer-alarm-notifier python-ceilometerclient

2.遥测服务使用数据库来存储信息。指定该数据库的配置文件。这些例子在控制器节点上使用 MongoDB 数据库：

apt-get install mongodb-server

注意: 作为文件的第一次开始，你必须创建 MongoDB 服务，停止服务并删除此更改生效的文件：

service mongodb stop

rm /var/lib/mongodb/journal/prealloc.*

service mongodb start

3、配置 MongoDB，使其监听控制器管理 IP 地址。（实例中连接mongodb有报错，提示no module bson.code,暂继续使用mysql）

vi /etc/mongodb.conf

bind_ip = 192.168.128.100

4、重启 MongoDB 服务，应用此配置变化：

service mongodb restart

5、创建数据库和 ceilometer 数据库用户：

mongo --host controller --eval ‘

db = db.getSiblingDB("ceilometer");

db.addUser({user: "ceilometer",

pwd: "feimeng",

roles: [ "readWrite", "dbAdmin" ]})‘

执行结果：

[email protected]:/home/mengfei#

MongoDB shell version: 2.4.9

connecting to: controller:27017/test

{

"user" : "ceilometer",

"pwd" : "01558b68f65459d46fc98a36d321ad3c",

"roles" : [

"readWrite",

"dbAdmin"

"_id" : ObjectId("546b06cfb06ccccdede9df3a")

}

[email protected]:/home/mengfei#

6.创建 ceilometer 用户身份服务。使用 service 租户，给用户 admin 角色

keystone user-create --name=ceilometer --pass=feimeng [email protected]

keystone user-role-add --user=ceilometer --tenant=service --role=admin

keystone service-create --name=ceilometer --type=metering --description="Telemetry"

keystone endpoint-create --service-id=$(keystone service-list | awk ‘/ metering / {print $2}‘)

--publicurl=http://controller:8777 \

--internalurl=http://controller:8777 \

--adminurl=http://controller:8777

[email protected]:/home/mengfei# keystone user-create --name=ceilometer --pass=feimeng [email protected]

+----------+----------------------------------+

| Property | Value |

+----------+----------------------------------+

| email | [email protected] |

| enabled | True |

| id | eb65831f16f44e05a477e45316f031c0 |

| name | ceilometer |

| username | ceilometer |

+----------+----------------------------------+

[email protected]:/home/mengfei# keystone user-role-add --user=ceilometer --tenant=service --role=admin

[email protected]:/home/mengfei# keystone service-create --name=ceilometer --type=metering --description="Telemetry"

+-------------+----------------------------------+

| Property | Value |

+-------------+----------------------------------+

| description | Telemetry |

| enabled | True |

| id | 7a0a1d1fdfe24ea294c36c499b6f0c1d |

| name | ceilometer |

| type | metering |

+-------------+----------------------------------+

[email protected]:/home/mengfei# keystone endpoint-create --service-id=$(keystone service-list | awk ‘/ metering / {print $2}‘)

--publicurl=http://controller:8777 \

> --publicurl=http://controller:8777 \

> --internalurl=http://controller:8777 \

> --adminurl=http://controller:8777

+-------------+----------------------------------+

| Property | Value |

+-------------+----------------------------------+

| adminurl | http://controller:8777 |

| id | edbb1187b4a34802ac1199c6fa5245e9 |

| internalurl | http://controller:8777 |

| publicurl | http://controller:8777 |

| region | regionOne |

| service_id | 7a0a1d1fdfe24ea294c36c499b6f0c1d |

你必须定义一个用作遥测之间的服务共享的密钥节点。使用 OpenSSL 生成一个随机的令牌，并将其存储在配置文件中：

openssl rand -hex 10

fb6f28f1257f2806de9a

7.编辑配置文件

vi /etc/ceilometer/ceilometer.conf

[DEFAULT]

rpc_backend = rabbit

rabbit_host = controller

rabbit_password = guest

auth_strategy = keystone

log_dir = /var/log/ceilometer

[database]

connection = mongodb://ceilometer:[email protected]:27017/ceilometer

[keystone_authtoken]

auth_uri = http://controller:5000/v2.0

identity_uri = http://controller:35357

admin_tenant_name = service

admin_user = ceilometer

admin_password = feimeng

[service_credentials]

os_auth_url = http://controller:5000/v2.0

os_username = ceilometer

os_tenant_name = service

os_password = feimeng

[publisher]

metering_secret = CEILOMETER_TOKEN (填写上边生成的随机值)

8、重启服务

service ceilometer-agent-central restart

service ceilometer-agent-notification restart

service ceilometer-api restart

service ceilometer-collector restart

service ceilometer-alarm-evaluator restart

service ceilometer-alarm-notifier restart

（二）在计算节点上

1.安装计算代理遥测

apt-get install ceilometer-agent-compute

2.编辑/etc/nova/nova.conf

vi /etc/nova/nova.conf

[DEFAULT]

...

instance_usage_audit = True

instance_usage_audit_period = hour

notify_on_state_change = vm_and_task_state

notification_driver = nova.openstack.common.notifier.rpc_notifier

notification_driver = ceilometer.compute.nova_notifier

3.重启计算服务：

service nova-compute restart

4.vi /etc/ceilometer/ceilometer.conf

[DEFAULT]

rpc_backend = rabbit

rabbit_host = controller

rabbit_password = quest

log_dir = /var/log/ceilometer

[keystone_authtoken]

auth_uri = http://controller:5000/v2.0

identity_uri = http://controller:35357

admin_tenant_name = service

admin_user = ceilometer

admin_password = feimeng

[service_credentials]

os_auth_url = http://controller:5000/v2.0

os_username = ceilometer

os_tenant_name = service

os_password = feimeng

os_endpoint_type = internalURL

[publisher]

# Secret value for signing metering messages (string value)

metering_secret = CEILOMETER_PASS (随机值）

5.重启其新设置的服务

service ceilometer-agent-compute restart

（三）配置遥测 Image 服务

1、vi /etc/glance/glance-api.conf

notification_driver = messaging

rpc_backend = rabbit

rabbit_host = controller

rabbit_password = guest

2、重启新的设置：

service glance-registry restart

service glance-api restart

（四）添加块存储服务代理遥测

1、在控制节点和卷节点上添加[DEFAULT]部分：

vi /etc/cinder/cinder.conf

control_exchange = cinder

notification_driver = cinder.openstack.common.notifier.rpc_notifier

2、重启块存储服务。

在控制节点上：

service cinder-api restart

service cinder-scheduler restart

在卷节点上（volume node）：

service cinder-volume restart

（五）配置对象存储服务遥测

要检索对象存储的统计数据，遥测服务需要访问对象存储与 ResellerAdmin角色。

给这个角色，os_username 用户，os_tenant_name 租户：

keystone role-create --name=ResellerAdmin

[email protected]:/home/mengfei# keystone role-create --name=ResellerAdmin

+----------+----------------------------------+

| Property | Value |

+----------+----------------------------------+

| id | 408abd397fcc4c15b326f9ea7766ca8f |

| name | ResellerAdmin |

+----------+----------------------------------+

[email protected]:/home/mengfei#

keystone user-role-add --tenant service --user ceilometer --role ResellerAdmin

（2）您还必须添加遥测中间件对象存储来处理传入和出站流量

vi /etc/swift/proxy-server.conf

[filter:ceilometer]

use = egg:ceilometer#swift

[pipeline:main]

pipeline = healthcheck cache authtoken keystoneauth ceilometer proxyserver

注：添加了ceilometer后，swift-proxy无法启动，原因未知

（3）重启其新设置的服务：

service swift-proxy restart

（六）验证遥测ceilometer安装

为了测试遥测安装，从镜像服务下载镜像，并使用 ceilometer 命令显示使用情况统计。

（1）使用 ceilometer meter-list 命令来测试：

ceilometer meter-list //列举所有测量值

ceilometer meter-list -q resource_id=XXX //列举某一实例测量值

ceilometer sample-list -m cpu -q resource_id=XXX //列举某一实例的cpu采样数据

ceilometer sample-list -m cpu_util -q ‘resource_id=b7fc623d-1d4a-4ac7-b96b-78c9d921fa74;timestamp>2013-05-21T03:18:20;timestamp<2013-05-21T03:30:20‘

ceilometer statistics -m cpu //列举实例的统计数据

ceilometer resource-list //列举所有实例列表

GET http://controller:8777/v2/meters 测试，暂不行，也许网络上的不对，实际ceilometer命令验证都正常

+---------------------------------+-------+--------+------------------------------------------+---------+----------------------------------+

+---------------------------------+-------+--------+------------------------------------------+---------+----------------------------------+

[email protected]:/var/log/ceilometer#

（2）从镜像服务下载镜像：

glance image-download "cirros-0.3.3-i386-disk" > cirros.img

[email protected]:/home/mengfei# glance image-download "cirros-0.3.3-i386-disk" > cirros.img

[email protected]:/home/mengfei# ll cirros.img

-rw-r--r-- 1 root root 12268032 11月 18 17:10 cirros.img

[email protected]:/home/mengfei#

（3）调用 ceilometer meter-list 命令再次验证下载，已被检测到，并通过遥测存储：

ceilometer meter-list 检测到image.download

[email protected]:/home/mengfei# ceilometer meter-list
