Pranav Salunke 0f504dced7 install-guide: Remove extra restarting of service

Restarting mongodb service is not required since we are stopping and
starting the service in the step above and restarting the services does
the same thing.

Install and configure controller node

This section describes how to install and configure the Telemetry module, code-named ceilometer, on the controller node. The Telemetry module uses separate agents to collect measurements from each OpenStack service in your environment.

To configure prerequisites

Before you install and configure Telemetry, you must install MongoDB, create a MongoDB database, service credentials, and API endpoint.

obs

Enable the Open Build Service repositories for MongoDB based on your openSUSE or SLES version:

On openSUSE:

# zypper addrepo -f obs://server:database/openSUSE_13.2 Database

On SLES:

# zypper addrepo -f obs://server:database/SLE_12 Database

Note

The packages are signed by GPG key 562111AC05905EA8. You should verify the fingerprint of the imported GPG key before using it.

Install the MongoDB package:

# zypper install mongodb

rdo

Install the MongoDB package:
```
# yum install mongodb-server mongodb
```

ubuntu

Install the MongoDB package:

# apt-get install mongodb-server mongodb-clients python-pymongo

obs

Edit the /etc/mongodb.conf file and complete the following actions:
1. Configure the bind_ip key to use the management interface IP address of the controller node.
```
bind_ip = 10.0.0.11
```
2. By default, MongoDB creates several 1 GB journal files in the /var/lib/mongodb/journal directory. If you want to reduce the size of each journal file to 128 MB and limit total journal space consumption to 512 MB, assert the smallfiles key:
```
smallfiles = true
```
  You can also disable journaling. For more information, see the MongoDB manual.
3. Start the MongoDB services and configure them to start when the system boots:
```
# systemctl enable mongodb.service
# systemctl start mongodb.service
```

rdo

Edit the /etc/mongod.conf file and complete the following actions:
1. Configure the bind_ip key to use the management interface IP address of the controller node.
```
bind_ip = 10.0.0.11
```
2. By default, MongoDB creates several 1 GB journal files in the /var/lib/mongodb/journal directory. If you want to reduce the size of each journal file to 128 MB and limit total journal space consumption to 512 MB, assert the smallfiles key:
```
smallfiles = true
```
  You can also disable journaling. For more information, see the MongoDB manual.
3. Start the MongoDB services and configure them to start when the system boots:
```
# systemctl enable mongod.service
# systemctl start mongod.service
```

ubuntu

Edit the /etc/mongodb.conf file and complete the following actions:
1. Configure the bind_ip key to use the management interface IP address of the controller node.
```
bind_ip = 10.0.0.11
```
2. By default, MongoDB creates several 1 GB journal files in the /var/lib/mongodb/journal directory. If you want to reduce the size of each journal file to 128 MB and limit total journal space consumption to 512 MB, assert the smallfiles key:
```
smallfiles = true
```
  If you change the journaling configuration, stop the MongoDB service, remove the initial journal files, and start the service:
```
# service mongodb stop
# rm /var/lib/mongodb/journal/prealloc.*
# service mongodb start
```
  You can also disable journaling. For more information, see the MongoDB manual.

Create the ceilometer database:

# mongo --host controller --eval '
  db = db.getSiblingDB("ceilometer");
  db.addUser({user: "ceilometer",
  pwd: "CEILOMETER_DBPASS",
  roles: [ "readWrite", "dbAdmin" ]})'

MongoDB shell version: 2.4.x
connecting to: controller:27017/test
{
 "user" : "ceilometer",
 "pwd" : "72f25aeee7ad4be52437d7cd3fc60f6f",
 "roles" : [
  "readWrite",
  "dbAdmin"
 ],
 "_id" : ObjectId("5489c22270d7fad1ba631dc3")
}

Replace CEILOMETER_DBPASS with a suitable password.

rdo

Create the ceilometer database:

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

MongoDB shell version: 2.6.x
connecting to: controller:27017/test
Successfully added user: { "user" : "ceilometer", "roles" : [ "readWrite", "dbAdmin" ] }

Replace CEILOMETER_DBPASS with a suitable password.

Source the admin credentials to gain access to admin-only CLI commands:
```
$ source admin-openrc.sh
```

To create the service credentials, complete these steps:

Create the ceilometer user:

$ openstack user create --password-prompt ceilometer
User Password:
Repeat User Password:
+----------+----------------------------------+
| Field    | Value                            |

| username | ceilometer                       |
+----------+----------------------------------+

Add the admin role to the ceilometer user.

$ openstack role add --project service --user ceilometer admin

+-------+----------------------------------+

Create the ceilometer service entity:

$ openstack service create --name ceilometer \
  --description "Telemetry" metering
+-------------+----------------------------------+
| Field       | Value                            |

$ openstack endpoint create \
  --publicurl http://controller:8777 \
  --internalurl http://controller:8777 \
  --adminurl http://controller:8777 \
  --region RegionOne \

To install and configure the Telemetry module components

obs

Install the packages:

# zypper install openstack-ceilometer-api \
  openstack-ceilometer-collector \
  openstack-ceilometer-agent-notification \
  openstack-ceilometer-agent-central python-ceilometerclient \
  openstack-ceilometer-alarm-evaluator \
  openstack-ceilometer-alarm-notifier

rdo

Install the packages:

# yum install openstack-ceilometer-api \
  openstack-ceilometer-collector openstack-ceilometer-notification \
  openstack-ceilometer-central openstack-ceilometer-alarm \
  python-ceilometerclient

ubuntu

Install the packages:

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

Generate a random value to use as the telemetry secret:
```
$ openssl rand -hex 10
```
Edit the /etc/ceilometer/ceilometer.conf file and complete the following actions:
1. In the [database] section, configure database access:
```
[database]
...
connection = mongodb://ceilometer:CEILOMETER_DBPASS@controller:27017/ceilometer
```
  Replace CEILOMETER_DBPASS with the password you chose for the Telemetry module database. You must escape special characters such as ':', '/', '+', and '@' in the connection string in accordance with RFC2396.
2. In the [DEFAULT] and [oslo_messaging_rabbit] sections, configure RabbitMQ message queue access:
```
[DEFAULT]
...
rpc_backend = rabbit

[oslo_messaging_rabbit]
...
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS
```
  Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.
3. In the [DEFAULT] and [keystone_authtoken] sections, configure Identity service access:
```
[DEFAULT]
...
auth_strategy = keystone

[keystone_authtoken]
...
auth_uri = http://controller:5000/v2.0
identity_uri = http://controller:35357
admin_tenant_name = service
admin_user = ceilometer
admin_password = CEILOMETER_PASS
```
  Replace CEILOMETER_PASS with the password you chose for the ceilometer user in the Identity service.
  
  Note
  
  Comment out any auth_host, auth_port, and auth_protocol options because the identity_uri option replaces them.
4. In the [service_credentials] section, configure service credentials:
```
[service_credentials]
...
os_auth_url = http://controller:5000/v2.0
os_username = ceilometer
os_tenant_name = service
os_password = CEILOMETER_PASS
os_endpoint_type = internalURL
os_region_name = RegionOne
```
  Replace CEILOMETER_PASS with the password you chose for the ceilometer user in the Identity service.
5. In the [publisher] section, configure the telemetry secret:
```
[publisher]
...
telemetry_secret = TELEMETRY_SECRET
```
  Replace TELEMETRY_SECRET with the telemetry secret that you generated in a previous step.
obs
1. In the [collector] section, configure the dispatcher:
```
[collector]
...
dispatcher = database
```
2. (Optional) To assist with troubleshooting, enable verbose logging in the [DEFAULT] section:
```
[DEFAULT]
...
verbose = True
```
rdo or ubuntu
1. (Optional) To assist with troubleshooting, enable verbose logging in the [DEFAULT] section:
```
[DEFAULT]
...
verbose = True
```
