openstack Rocky版本安装和配置ceilometer服务教程
逄嘉木
写在前面
1、openstack版本：rocky
2、linux版本：centos7
3、确保集群已经安装nova、glance、keystone等
4、有$符号的是命令，没有的是文本，本文代码中#号为注释
首先确保已经具备了基础的openstack环境，确保计算（Compute）、镜像（Image）和身份（Identity）服务。
目录
1、安装和配置ceilometer（本节命令运行在控制节点上）
2、启用cinder计量器（本节命令在控制器和块存储节点上都运行）
5、启用neutron服务计量器（本节命令运行在控制节点上）
1、安装和配置ceilometer（本节命令运行在控制节点上）
配置发送计量数据的端点——Gnocchi
获取admin凭据使用属于管理员的命令行命令
$ source admin-openstack.sh创建ceilometer用户
$ openstack user create --domain default --password-prompt ceilometer将admin角色添加给ceilometer用户
$ openstack role add --project service --user ceilometer admin在 Keystone 中注册 Gnocchi 服务
创建gnocchi用户
$ openstack user create --domain default --password-prompt gnocchi创建gnocchi服务实体
$ openstack service create --name gnocchi \
--description "Metric Service" metric将admin角色添加给gnocchi用户
$ openstack role add --project service --user gnocchi admin创建 Metric 服务 API 端点
$ openstack endpoint create --region RegionOne \
metric public http://controller:8041$ openstack endpoint create --region RegionOne \
metric internal http://controller:8041$ openstack endpoint create --region RegionOne \
metric admin http://controller:8041安装Gnocchi
$ yum install openstack-gnocchi-api openstack-gnocchi-metricd \
python-gnocchiclient创建数据库
$ mysql -u root -p
CREATE DATABASE gnocchi;
GRANT ALL PRIVILEGES ON gnocchi.* TO 'gnocchi'@'localhost' \
IDENTIFIED BY 'gnocchi';
GRANT ALL PRIVILEGES ON gnocchi.* TO 'gnocchi'@'%' \
IDENTIFIED BY 'gnocchi';编辑配置文件的keystone选项,注意你自己的密码
$ vim /etc/gnocchi/gnocchi.conf
[api]
auth_mode = keystone
[keystone_authtoken]
auth_type = password
auth_url = http://controller:5000/v3
project_domain_name = Default
user_domain_name = Default
project_name = service
username = gnocchi
password = 1234
interface = internalURL
region_name = RegionOne
[indexer]
url = mysql+pymysql://gnocchi:gnocchi@controller/gnocchi
[storage]
coordination_url = redis://controller:6379
file_basepath = /var/lib/gnocchi
driver = file
控制节点需要安装redis以启用6379端口。
redis安装
#首先安装编译环境c++
$ yum install gcc-c++
# 在线下载redis
$ wget http://download.redis.io/releases/redis-2.8.18.tar.gz
#解压
$ tar xzf redis-2.8.18.tar.gz
cd redis-2.8.18
#运行make命令
$ make prefix=/usr/local/redis install
#安装完成后在/usr/local/redis/bin下有几个可执行文件
#修改redis.conf
daemonize yes
#拷贝配置文件
$ cp redis.conf /usr/local/redis
#启动redis
$ cd /usr/local/redis/
#执行
$ ./bin/redis-server ./redis.conf
#即可查看端口情况
$ ps -ef | grep -i redis初始化Gnocchi
$ gnocchi-upgrade完成 Gnocchi 安装
启动 Gnocchi 服务并将它们配置为在系统启动时启动
$ systemctl enable openstack-gnocchi-api.service \
openstack-gnocchi-metricd.service
$ systemctl start openstack-gnocchi-api.service \
openstack-gnocchi-metricd.service安装和配置组件
安装 Ceilometer 软件包
$ yum install openstack-ceilometer-notification \
openstack-ceilometer-central编辑/etc/ceilometer/pipeline.yaml文件
$ vim /etc/ceilometer/pipeline.yaml
#配置 Gnocchi 连接
publishers:
- gnocchi://?filter_project=service&archive_policy=low
编辑/etc/ceilometer/ceilometer.conf文件
$ vim /etc/ceilometer/ceilometer.conf
[DEFAULT]
transport_url = rabbit://openstack:openstack@controller
[service_credentials]
auth_type = password
auth_url = http://controller:5000/v3
project_domain_id = default
user_domain_id = default
project_name = service
username = ceilometer
password = 1234
interface = internalURL
region_name = RegionOne在 Gnocchi 中创建 Ceilometer 资源
$ ceilometer-upgrade完成安装
$ systemctl enable openstack-ceilometer-notification.service \
openstack-ceilometer-central.service
$ systemctl start openstack-ceilometer-notification.service \
openstack-ceilometer-central.service2、启用cinder计量器（本节命令在控制器和块存储节点上都运行）
编辑/etc/cinder/cinder.conf文件并完成以下操作
$ vim /etc/cinder/cinder.conf
[oslo_messaging_notifications]
driver = messagingv2
启用与块存储相关的定期使用统计
$ cinder-volume-usage-audit --start_time='YYYY-MM-DD HH:MM:SS' \
--end_time='YYYY-MM-DD HH:MM:SS' --send_actions或者使用cron计划任务服务
$ yum install yum-cron
$ vim cron.sh
*/5 * * * * /path/to/cinder-volume-usage-audit --send_actions
#每五分钟运行一次
$ crontab -u root cron.sh完成安装
重启控制器节点上的块存储服务
$ systemctl restart openstack-cinder-api.service openstack-cinder-scheduler.service重启存储节点上的块存储服务
$ systemctl restart openstack-cinder-volume.service3、启用glance服务计量器（本节命令运行在控制节点上）
编辑/etc/glance/glance-api.conf和
$ vim /etc/glance/glance-registry.conf
[DEFAULT]
transport_url = rabbit://openstack:RABBIT_PASS@controller

编辑/etc/neutron/neutron.conf并完成以下操作
$vim /etc/neutron/neutron.conf
[oslo_messaging_notifications]
driver = messagingv2重启网络服务
$ systemctl restart neutron-server.service6、启用swift服务计量器（本节命令运行在控制节点上）
ceilometer服务需要使用ResellerAdmin角色访问对象存储服务
$ source admin-openstack.sh创建ResellerAdmin角色
$ openstack role create ResellerAdmin将ResellerAdmin角色添加到ceilometer用户
$ openstack role add --project service --user ceilometer ResellerAdmin安装软件包
$ yum install python-ceilometermiddleware编辑/etc/swift/proxy-server.conf文件并完成以下操作
$ vim /etc/swift/proxy-server.conf
[filter:keystoneauth]
operator_roles = admin, user, ResellerAdmin
[pipeline:main]
pipeline = catch_errors gatekeeper healthcheck proxy-logging cache container_sync bulk ratelimit authtoken keystoneauth container-quotas account-quotas slo dlo versioned_writes proxy-logging ceilometer proxy-server
[filter:ceilometer]
paste.filter_factory = ceilometermiddleware.swift:filter_factory
control_exchange = swift
url = rabbit://openstack:openstack@controller:5672/
driver = messagingv2
topic = notifications
log_level = WARN完成安装
$ systemctl restart openstack-swift-proxy.service7、启用计算服务计量器（本节命令在计算节点上运行）
安装软件包

$ yum install openstack-ceilometer-ipmi 编辑/etc/ceilometer/ceilometer.conf文件并完成以下操作注意密码
$ vim /etc/ceilometer/ceilometer.conf
[DEFAULT]
transport_url = rabbit://openstack:openstack@controller
[service_credentials]
auth_url = http://controller:5000
project_domain_id = default
user_domain_id = default
auth_type = password
username = ceilometer
project_name = service
password = 1234
interface = internalURL
region_name = RegionOne编辑/etc/nova/nova.conf文件并在部分中配置通知
$ vim /etc/nova/nova.conf
[DEFAULT]
instance_usage_audit = True
instance_usage_audit_period = hour
notify_on_state_change = vm_and_task_state
[oslo_messaging_notifications]
driver = messagingv2配置计算以轮询 IPMI 仪表
编辑/etc/sudoers文件
ceilometer ALL = (root) NOPASSWD: /usr/bin/ceilometer-rootwrap /etc/ceilometer/rootwrap.conf *编辑/etc/ceilometer/polling.yaml以包含所需的仪表
$ vim /etc/ceilometer/polling.yaml
- name: ipmi
interval: 300
meters:
- hardware.ipmi.temperature完成安装
$ systemctl enable openstack-ceilometer-compute.service
$ systemctl start openstack-ceilometer-compute.service
$ systemctl enable openstack-ceilometer-ipmi.service
$ systemctl start openstack-ceilometer-ipmi.service 重启计算服务
$ systemctl restart openstack-nova-compute.service8、验证操作
$ source admin-openstack.sh
$ gnocchi resource list --type image
$ gnocchi resource show ID
#将id换成上一步生成的id如果报AttributeError: _Environ instance has no attribute ‘set‘的错误
File "/usr/lib/python2.7/site-packages/gnocchiclient/shell.py", line 131, in build_option_parser
os.environ.set("OS_AUTH_TYPE","password")
AttributeError: _Environ instance has no attribute 'set'
可以
就是将os.environ.set("OS_AUTH_TYPE","password")修改为os.environ["OS_AUTH_TYPE"]="password"
从图像服务下载 CirrOS 图像
$ IMAGE_ID=$(glance image-list | grep 'cirros' | awk '{ print $2 }')
$ glance image-download $IMAGE_ID > /tmp/cirros.img再次列出可用仪表以验证对图像下载的检测
$ gnocchi measures show ID删除之前下载的图像文件/tmp/cirros.img
$ rm /tmp/cirros.img
