# mkdir -p /root/MAINTENANCE/`date "+%Y%m%d"`/{bak,new}
# BAK=/root/MAINTENANCE/`date "+%Y%m%d"`/bak

CeiloMeterインストール

インストール

Telemetry Service
# apt-get -y install ceilometer-api ceilometer-collector ceilometer-agent-central ceilometer-agent-notification ceilometer-alarm-evaluator ceilometer-alarm-notifier python-ceilometerclient

Database Store
#  apt-get -y install mongodb-server

DBサイズがデフォルトで1GBのため、節約する
# service mongodb stop
# rm /var/lib/mongodb/journal/prealloc.*

bindするInterfaceを変更する
# cp -p /etc/mongodb.conf $BAK
# sed -i 's/bind_ip = 127.0.0.1/bind_ip = 192.168.0.200/' /etc/mongodb.conf
# diff -u $BAK/mongodb.conf /etc/mongodb.conf
---
-bind_ip = 127.0.0.1
+bind_ip = 192.168.0.200
---
# service mongodb start
