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 +-----------------------------------------------------+-------+| Field | Value | +-----------------------------------------------------+-------+ | storage/number of metric having measures to process | 39 || storage/total number of measures to process | 39 | +-----------------------------------------------------+-------+
