OpenStack Newton : Ceilometer 設定#22016/12/22

OpenStack Metering Service（Ceilometer）を設定します。

ここでは以下のような構築済みの環境に Ceilometer を追加インストールして設定します。
例として、Network Node に Metering サービス一式をインストールして設定します。

	ここでは Ceilometer のインストールと設定をします。
[1]	Ceilometer はバックエンドDBに MongoDB を使用するため、インストールしておきます。

root@network:~#

apt-get -y install mongodb-server mongodb python-pymongo

[2]	MongoDB を起動します。

root@network:~#

vi /etc/mongodb.conf

# 11行目：変更

bind_ip =

0.0.0.0

root@network:~#

systemctl restart mongodb

# Ceilometer 用 DB作成 (password の箇所は任意のパスワードを設定)

root@network:~#

mongo --host 10.0.0.50 --eval '
db = db.getSiblingDB("ceilometer");
db.createUser({user: "ceilometer",
pwd: "password",
roles: [ "readWrite", "dbAdmin" ]})'

MongoDB shell version: 2.6.10
connecting to: 10.0.0.50:27017/test
Successfully added user: { "user" : "ceilometer", "roles" : [ "readWrite", "dbAdmin" ] }

[3]	Ceilometer をインストールします。

root@network:~#

apt-get -y install ceilometer-api ceilometer-collector ceilometer-agent-central ceilometer-agent-notification python-ceilometerclient python-ceilometerclient apache2 libapache2-mod-wsgi

[4]	Ceilometer を設定します。

root@network:~#

mv /etc/ceilometer/ceilometer.conf /etc/ceilometer/ceilometer.conf.org

root@network:~#

vi /etc/ceilometer/ceilometer.conf

a2ensite ceilometer

Enabling site ceilometer.
To activate the new configuration, you need to run:
service apache2 reload
root@network:~#

systemctl stop ceilometer-api

root@network:~#

systemctl disable ceilometer-api

root@network:~#

systemctl restart apache2

[6]	Ceilometer を起動します。

root@network:~#

systemctl restart ceilometer-agent-central \
ceilometer-agent-notification \
ceilometer-collector

root@network:~#

systemctl enable ceilometer-agent-central \
ceilometer-agent-notification \
ceilometer-collector
