OpenStack安装Ceilometer+Gnocchi（Pike版）

Centos7 下安装Ceilometer和Gnocchi，之前按照官网文档装，出现了一些坑，在网上搜了各种资料，最后成功安装，在此记录步骤。之后学习过程中可能会回来完善此文档。

Step1 准备

1.导入环境变量

. admin-openrc

2.创建ceilometer服务

• 创建ceilometer用户

openstack user create --domain default --password-prompt ceilometer

• 授予ceilometer用户管理员角色

openstack role add --project service --user ceilometer admin

• 创建ceilometer服务

openstack service create --name ceilometer \
  --description "Telemetry" metering

3.创建Gnocchi服务

• 创建gnocchi用户

openstack user create --domain default --password-prompt gnocchi

• 授予gnocchi用户管理员角色

openstack role add --project service --user gnocchi admin

• 创建gnocchi服务

openstack service create --name gnocchi \
  --description "Metric Service" metric

• 创建服务端点

openstack endpoint create --region RegionOne \
  metric public http://controller:8041openstack endpoint create --region RegionOne \
  metric internal http://controller:8041openstack endpoint create --region RegionOne \
  metric admin http://controller:8041

Step2 安装Gnocchi

1.安装软件包

yum install openstack-gnocchi-api openstack-gnocchi-metricd python-gnocchiclient -y

2.创建数据库

替换 GNOCCHI_DBPASS 为合适的密码

mysql -u root -p

CREATE DATABASE gnocchi;

GRANT ALL PRIVILEGES ON gnocchi.* TO 'gnocchi'@'localhost' IDENTIFIED BY 'GNOCCHI_DBPASS';
GRANT ALL PRIVILEGES ON gnocchi.* TO 'gnocchi'@'%' IDENTIFIED BY 'GNOCCHI_DBPASS';exit;

3.修改配置文件

重点来了

尝试过官网的配置，也尝试过网上各种各样的配置，在这个配置下，我成功了

vim /etc/gnocchi/gnocchi.conf

[keystone_authtoken]
auth_uri = http://controller:5000/v3auth_url = http://controller:35357/v3memcached_servers = controller:11211auth_type = password
project_domain_name = defaultuser_domain_name = defaultproject_name = service
username = gnocchi
password = GNOCCHI_PASSinterface = internalURL
region_name = RegionOne
auth_version = 3auth_port = 35357[api]
auth_mode = keystone

[database]
backend = sqlalchemy

[indexer]
url = mysql+pymysql://gnocchi:GNOCCHI_PASS@controllerv/gnocchi[storage]
file_basepath = /var/lib/gnocchi
driver = file

4.初始化Gnocchi

gnocchi-upgrade

5.启动服务

vim /usr/bin/gnocchi-api

找到如下这行

parser.add_argument('--port', '-p', type=int, default=8000,                        help='TCP port to listen on')

把8000改为8041

启动服务

systemctl enable openstack-gnocchi-api.service
systemctl start openstack-gnocchi-api

systemctl enable openstack-gnocchi-metricd 
systemctl start openstack-gnocchi-metricd

Step3 安装Ceilometer

1.安装软件包

yum install openstack-ceilometer-notification \
  openstack-ceilometer-central -y

2.修改配置文件

vim /etc/ceilometer/ceilometer.conf

[dispatcher_gnocchi]
filter_service_activity = False
archive_policy = low

[DEFAULT]
meter_dispatchers = gnocchi
event_dispatchers = gnocchi
transport_url = rabbit://openstack:RABBIT_PASS@controller[keystone_authtoken]
auth_uri = http://controller:5000/v3auth_url = http://controller:35357/v3memcached_servers = controller:11211auth_type = password
project_domain_name = defaultuser_domain_name = defaultproject_name = service
username = gnocchi
password = CEILOMETER_PASSinterface = internalURL
region_name = RegionOne

[service_credentials]
auth_uri = http://controller:5000/v3auth_url = http://controller:35357/v3memcached_servers = controller:11211auth_type = password
project_domain_name = defaultuser_domain_name = defaultproject_name = service
username = ceilometer
password = CEILOMETER_PASSinterface = internalURL
region_name = RegionOne

3.更新数据库

ceilometer-upgrade --skip-metering-database

4.启动服务

systemctl enable openstack-ceilometer-notification.service \  openstack-ceilometer-central.service
  systemctl start openstack-ceilometer-notification.service \  openstack-ceilometer-central.service

Step4 验证

运行：

. admin-openrc
gnocchi status

Unable to establish connection to http://localhost:8041/v1/status?details=False: HTTPConnectionPool(host='localhost', port=8041): Max retries exceeded with url: /v1/status?details=False (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7f895ad06e50>: Failed to establish a new connection: [Errno 111] \xe6\x8b\x92\xe7\xbb\x9d\xe8\xbf\x9e\xe6\x8e\xa5',))

为什么会这样？因为之前的环境变量里少了一个 export OS_AUTH_TYPE=password

在. admin-openrc里加入此环境变量如下：

export OS_PROJECT_DOMAIN_NAME=Defaultexport OS_USER_DOMAIN_NAME=Defaultexport OS_PROJECT_NAME=adminexport OS_USERNAME=adminexport OS_PASSWORD=PASSWORDexport OS_AUTH_URL=http://controller:35357/v3export OS_IDENTITY_API_VERSION=3export OS_IMAGE_API_VERSION=2export OS_AUTH_TYPE=password

再次运行：

gnocchi status
