Installation¶
This guide will help you install Freezer API framework in one of your OpenStack controller node. You can install Freeer API in stand alone virtual or bare metal server but it is strongly suggested install in controller node.
Before Installation¶
- Freezer Agent must be installed
- Use this guide to install Freezer Agent to OpenStack Controller node (Where you have installed Horizon and Keystone)
- Use corresponding release to your OpenStack version. For example; If your OpenStack version is Liberty, user stable/Liberty branch.
- Do not forget to register Keystone API endpoint and service
- Elasticsearch must be installed
Requirements¶
- elasticsearch>=1.3.0,<2.0 # Apache-2.0
- falcon>=0.1.6 # Apache-2.0
- jsonschema>=2.0.0,<3.0.0,!=2.5.0 # MIT
- keystonemiddleware>=4.0.0 # Apache-2.0
- oslo.config>=3.2.0 # Apache-2.0
- oslo.i18n>=1.5.0 # Apache-2.0
- six>=1.9.0 # MIT
- Freezer Agent & Scheduler installed from source
Ubuntu / Debian Installation¶
Follow these instructions if your OpenStack controller nodes are installed on Ubuntu or Debian based Linux distros
Install required packages first: (If you have installed Freezer Agent from source, following packages are already installed.)
sudo apt-get install -y python-dev python-pip git openssl gcc make automake
Clone proper branch of Freezer API with git:
git clone -b [branch] https://github.com/openstack/freezer-api.git
Install requirements with pip:
cd freezer-api/
sudo pip install -r requirements.txt
Install Freezer API from source:
sudo python setup.py install
Copy config file:
sudo cp etc/freezer-api.conf /etc/freezer-api.conf
Edit config file:
sudo nano /etc/freezer-api.conf
# change log file location
log_file = /var/log/freezer-api.log
# configure Keystone authentication
[keystone_authtoken]
auth_protocol = http
auth_host = [keystone_host_ip_or_hostname]
auth_port = 35357
admin_user = [freezer admin user] # admin or user with admin priviliges
admin_password = [admin password]
admin_tenant_name = [admin tenan] # usually admin
include_service_catalog = False
delay_auth_decision = False
[storage]
# supported db engine. currently elasticsearch only
db=elasticsearch
hosts='http://[elasticsearch host address]:9200'
# freezer-db-init uses the following parameter to set the number of replicas
number_of_replicas=1 # replicas must be set to 1
Follow this instructions to install Elasticsearch 1.7.5:
https://goo.gl/bwDcNK
service elasticsearch start
*You must install Elasticsearch 1.7.5 for Freezer API to work correctly*
Elasticsearch needs to know what type of data each document’s field contains. This information is contained in the “mapping”, or schema definition.
Elasticsearch will use dynamic mapping to try to guess the field type from the basic datatypes available in JSON, but some field’s properties have to be explicitly declared to tune the indexing engine.
Let’s initialize database:
freezer-db-init [db-host] # usually localhost
Run Freezer API:
freezer-api 0.0.0.0
There is not any Freezer API Deamon. If you need to run Freezer API in backgroun, user following commend:
freezer-api 0.0.0.0 >/dev/null 2>&1
Keystone API v2.0 endpoint registration:
keystone service-create --name freezer --type backup \
--description "Freezer Backup Service"
# use public IP address or hostname because Freezer Scheduler must be able
to reach API from public IP or hostname.
# default port is 9090. If you have changed in freezer-api.conf you must
change it here too.
keystone endpoint-create \
--service-id $(keystone service-list | awk '/ backup / {print $2}') \
--publicurl http://[freezer_api_publicurl]:[port] \
--internalurl http://[freezer_api_internalurl]:[port] \
--adminurl http://[freezer_api_adminurl]:[port] \
--region regionOne
Keystone API v3 endpoint registration:
# With OpenStack Liberty, Keystone API v2.0 is depreciated and you will not
able to use "keystone-client" commend instead user "openstack" commend
openstack service create --name freezer \
--description "Freezer Backup Service" backup
# use public IP address or hostname because Freezer Scheduler must be able
to reach API from public IP or hostname.
# default port is 9090. If you have changed in freezer-api.conf you must
change it here too.
openstack endpoint create --publicurl http://176.53.94.101:9090 \
--internalurl http://192.168.0.4:9090 \
--adminurl http://176.53.94.101:9090 \
--region RegionOne backup
