We can configure Masakari by following two ways:

1.	Installed along with devstack by enabling Masakari in local.conf
		[[local|localrc]]
		HOST_IP=<CONTROLLER_IP>
		FLAT_INTERFACE=eth0
		LOGFILE=/opt/stack/logs/stack.sh.log
		LOG_DAYS=3
		ADMIN_PASSWORD=admin
		MYSQL_PASSWORD=admin
		RABBIT_PASSWORD=admin
		SERVICE_PASSWORD=admin
		SERVICE_TOKEN=xyzpdqlazydog
		VOLUME_BACKING_FILE_SIZE=97280M
		enable_plugin masakari https://opendev.org/openstack/masakari




2.	Installed Masakari separately if openstack is installed earlier using devstack
	a.	Prerequisites:
		i.	Openstack installation using devstack

	b.	Steps:
		i.	DB creation
		
	1.	Masakari uses taskflow internally to log notification process flow
		So along with Masakari DB tables, ‘taskflow’ DB tables are also created. ‘taskflow’ DB creation has dependency on ‘sqlalchemy_utils’, so installed separately using

									pip install sqlalchemy_utils

	2.	Create database at sql

		CREATE DATABASE masakari CHARACTER SET utf8;

	ii.	User and endpoint creation
		Followed ‘https://opendev.org/openstack/masakari’ for user and endpoint creation:

			openstack user create --password-prompt masakari
			(given password as masakari)
			openstack role add --project service --user masakari admin
			openstack service create --name masakari --description "masakari high availability" instance-ha

			openstack endpoint create --region RegionOne masakari admin http:// <CONTROLLER_IP>/instance-ha/v1/$\(tenant_id\)s
			openstack endpoint create --region RegionOne masakari public http:// <CONTROLLER_IP>/instance-ha/v1/$\(tenant_id\)s
			openstack endpoint create --region RegionOne masakari internal http:// <CONTROLLER_IP>/instance-ha/v1/$\(tenant_id\)s

	iii.	Pull the repositories from github under /opt/stack’, do not installed yet.

		git clone https://opendev.org/openstack/masakari
		git clone https://github.com/openstack/python-masakariclient.git

	iv.	Generate masakari configuration file
		1.	Go to ‘opt/stack/masakari’ and execute below command, this will generate ‘masakari.conf.sample’, sample configuration file at ‘/opt/stack/masakari/etc/masakari/’

			tox -e genconfig


	2.	Rename this sample file as ‘masakari.conf’ and edit below section only. 
		Note that password configured under [keystone_authtoken] section is same as we entered during user creation in earlier step.
		Once edit done, move this file under ‘etc/masakari’

			[DEFAULT]
			transport_url = rabbit://stackrabbit:admin@<CONTROLLER_IP>:5672/
			graceful_shutdown_timeout = 5
			os_privileged_user_tenant = service
			os_privileged_user_password = admin
			os_privileged_user_auth_url = http:// <CONTROLLER_IP>/identity
			os_privileged_user_name = nova
			logging_exception_prefix = %(color)s%(asctime)s.%(msecs)03d TRACE %(name)s [01;35m%(instance)s[00m
			logging_debug_format_suffix = [00;33mfrom (pid=%(process)d) %(funcName)s %(pathname)s:%(lineno)d[00m
			logging_default_format_string = %(asctime)s.%(msecs)03d %(color)s%(levelname)s %(name)s [[00;36m-%(color)s] [01;35m%(instance)s%(color)s%(message)s[00m
			logging_context_format_string = %(asctime)s.%(msecs)03d %(color)s%(levelname)s %(name)s [[01;36m%(request_id)s [00;36m%(project_name)s %(user_name)s%(color)s] [01;35m%(instance)s%(color)s%(message)s[00m
			use_syslog = False
			debug = True
			masakari_api_workers = 2

			[database]
			connection = mysql+pymysql://root:admin@127.0.0.1/masakari?charset=utf8

			[keystone_authtoken]
			memcached_servers = localhost:11211
			cafile = /opt/stack/data/ca-bundle.pem
			project_domain_name = Default
			project_name = service
			user_domain_name = Default
			password = masakari
			username = masakari
			auth_url = http:// <CONTROLLER_IP>/identity
			auth_type = password


			[taskflow]
			connection = mysql+pymysql://root:admin@127.0.0.1/masakari?charset=utf8

	v.	Copy 'masakari/etc/api-paste' files to location as below:
		a.	Copy below files to ‘/etc/masakari’ location
			ii.	api-paste


	vii.	Now install ‘masakari’ and client
		1.	Go to /opt/stack/masakari’ and execute

			python setup.py install
			
		2. run below to sync Database
			masakari-manage db sync

		3.	Go to /opt/stack/python-masakariclient’ and execute

			python setup.py install


	viii.	Verify services by executing
			masakari-api
			masakari-engine

	ix.	Masakari provides below CLI commands, use ‘help’ keyword for argument list

		1.	Segment related
		'segment-create', 'segment-delete', 'segment-list', 'segment-show', 'segment-update'
		2.	Host related
		'host-create', 'host-delete', 'host-list', 'host-show', 'host-update', 
		3.	Notification related
		'notification-create', 'notification-list', 'notification-show',
