Install and Configure Ceilometer on this section.
|
|
| [1] | Install MongoDB which Ceilometer needs for backend database. |
|
# install from EPEL [root@network ~]# yum --enablerepo=epel -y install mongodb-server mongodb
|
| [2] | Configure and Start MongoDB. |
|
[root@network ~]#
vi /etc/sysconfig/mongod # add OPTIONS=" --smallfiles --quiet -f /etc/mongodb.conf"
[root@network ~]#
vi /etc/mongodb.conf # line 4: change to the own IP bind_ip = 10.0.0.50
# create a DB for Ceilometer (set any password for "password" section) [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: 2.6.5 connecting to: 10.0.0.50:27017/test Successfully added user: { "user" : "ceilometer", "roles" : [ "readWrite", "dbAdmin" ] } |
| [3] | Install Ceilometer services. |
|
[root@network ~]# yum --enablerepo=openstack-juno,epel -y install openstack-ceilometer-api openstack-ceilometer-collector openstack-ceilometer-notification openstack-ceilometer-central openstack-ceilometer-alarm python-ceilometerclient
|
| [4] | Configure Ceilometer. |
|
