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/mongod.conf # line 6: change to the own IP bind_ip = 10.0.0.50
# create a DataBase 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: 2.6.9 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-kilo,epel -y install openstack-ceilometer-api openstack-ceilometer-collector openstack-ceilometer-notification openstack-ceilometer-central openstack-ceilometer-alarm python-ceilometerclient python-oslo-policy
|
[4] | Configure Ceilometer. |
[root@network ~]# mv /etc/ceilometer/ceilometer.conf /etc/ceilometer/ceilometer.conf.org
[root@network ~]#
vi /etc/ceilometer/ceilometer.conf # create new
