Manual Installation

This document describes how to install and run Tacker manually.

Pre-requisites

1). Ensure that OpenStack components Keystone, Mistral, Barbican and Horizon are installed. Refer the list below for installation of these OpenStack projects on different Operating Systems.

• https://docs.openstack.org/keystone/latest/install/index.html
• https://docs.openstack.org/mistral/latest/install/index.html
• https://docs.openstack.org/barbican/latest/install/install.html
• https://docs.openstack.org/horizon/latest/install/index.html

2). one admin-openrc.sh file is generated. one sample admin-openrc.sh file is like the below:

export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=KTskN5eUMTpeHLKorRcZBBbH0AM96wdvgQhwENxY
export OS_AUTH_URL=http://localhost:5000/identity
export OS_INTERFACE=internal
export OS_IDENTITY_API_VERSION=3
export OS_REGION_NAME=RegionOne

Installing Tacker server

Note

The paths we are using for configuration files in these steps are with reference to Ubuntu Operating System. The paths may vary for other Operating Systems.

The branch_name which is used in commands, specify the branch_name as “stable/<branch>” for any stable branch installation. For eg: stable/ocata, stable/newton. If unspecified the default will be “master” branch.

1). Create MySQL database and user.

mysql -uroot -p
CREATE DATABASE tacker;
GRANT ALL PRIVILEGES ON tacker.* TO 'tacker'@'localhost' \
    IDENTIFIED BY '<TACKERDB_PASSWORD>';
GRANT ALL PRIVILEGES ON tacker.* TO 'tacker'@'%' \
    IDENTIFIED BY '<TACKERDB_PASSWORD>';
exit;

Note

Replace TACKERDB_PASSWORD with your password.

2). Create users, roles and endpoints:

a). Source the admin credentials to gain access to admin-only CLI commands:

. admin-openrc.sh

b). Create tacker user with admin privileges.

Note

Project_name can be “service” or “services” depending on your OpenStack distribution.

openstack user create --domain default --password <PASSWORD> tacker
openstack role add --project service --user tacker admin

c). Create tacker service.

openstack service create --name tacker \
    --description "Tacker Project" nfv-orchestration

d). Provide an endpoint to tacker service.

If you are using keystone v3 then,

openstack endpoint create --region RegionOne nfv-orchestration \
           public http://<TACKER_NODE_IP>:9890/
openstack endpoint create --region RegionOne nfv-orchestration \
           internal http://<TACKER_NODE_IP>:9890/
openstack endpoint create --region RegionOne nfv-orchestration \
           admin http://<TACKER_NODE_IP>:9890/

If you are using keystone v2 then,

openstack endpoint create --region RegionOne \
     --publicurl 'http://<TACKER_NODE_IP>:9890/' \
     --adminurl 'http://<TACKER_NODE_IP>:9890/' \
     --internalurl 'http://<TACKER_NODE_IP>:9890/' <SERVICE-ID>

3). Clone tacker repository.

cd ~/
git clone https://github.com/openstack/tacker -b <branch_name>

4). Install all requirements.

cd tacker
sudo pip install -r requirements.txt

5). Install tacker.

sudo python setup.py install

6). Create ‘tacker’ directory in ‘/var/log’.

sudo mkdir /var/log/tacker

7). Generate the tacker.conf.sample using tools/generate_config_file_sample.sh

or ‘tox -e config-gen’ command. Rename the “tacker.conf.sample” file at “etc/tacker/” to tacker.conf. Then edit it to ensure the below entries:

Note

Ignore any warnings generated while using the “generate_config_file_sample.sh”.

Note

project_name can be “service” or “services” depending on your OpenStack distribution in the keystone_authtoken section.

Note

The path of tacker-rootwrap varies according to the operating system, e.g. it is /usr/bin/tacker-rootwrap for CentOS, therefore the configuration for [agent] should be like:

[agent]
root_helper = sudo /usr/bin/tacker-rootwrap /usr/local/etc/tacker/rootwrap.conf

[DEFAULT]
auth_strategy = keystone
policy_file = /usr/local/etc/tacker/policy.json
debug = True
use_syslog = False
bind_host = <TACKER_NODE_IP>
bind_port = 9890
service_plugins = nfvo,vnfm

state_path = /var/lib/tacker
...

[nfvo_vim]
vim_drivers = openstack

[keystone_authtoken]
memcached_servers = 11211
region_name = RegionOne
auth_type = password
project_domain_name = <DOMAIN_NAME>
user_domain_name = <DOMAIN_NAME>
username = <TACKER_USER_NAME>
project_name = service
password = <TACKER_SERVICE_USER_PASSWORD>
auth_url = http://<KEYSTONE_IP>:5000
www_authenticate_uri = http://<KEYSTONE_IP>:5000
...

[agent]
root_helper = sudo /usr/local/bin/tacker-rootwrap /usr/local/etc/tacker/rootwrap.conf
...

[database]
connection = mysql+pymysql://tacker:<TACKERDB_PASSWORD>@<MYSQL_IP>:3306/tacker?charset=utf8
...

[tacker]
monitor_driver = ping,http_ping

8). Copy the tacker.conf file to “/usr/local/etc/tacker/” directory

sudo su
cp etc/tacker/tacker.conf /usr/local/etc/tacker/

9). Populate Tacker database:

Note

The path of tacker-db-manage varies according to the operating system, e.g. it is /usr/bin/tacker-bin-manage for CentOS

/usr/local/bin/tacker-db-manage --config-file /usr/local/etc/tacker/tacker.conf upgrade head

10). To support systemd, copy tacker.service and tacker-conductor.service file to

“/etc/systemd/system/” directory, and restart systemctl daemon.

sudo su
cp etc/systemd/system/tacker.service /etc/systemd/system/
cp etc/systemd/system/tacker-conductor.service /etc/systemd/system/
systemctl daemon-reload

Note

Needs systemd support. By default Ubuntu16.04 onward is supported.

Install Tacker client

1). Clone tacker-client repository.

cd ~/
git clone https://github.com/openstack/python-tackerclient -b <branch_name>

2). Install tacker-client.

cd python-tackerclient
sudo python setup.py install

Install Tacker horizon

1). Clone tacker-horizon repository.

cd ~/
git clone https://github.com/openstack/tacker-horizon -b <branch_name>

2). Install horizon module.

cd tacker-horizon
sudo python setup.py install

3). Enable tacker horizon in dashboard.

sudo cp tacker_horizon/enabled/* \
    /usr/share/openstack-dashboard/openstack_dashboard/enabled/

4). Restart Apache server.

sudo service apache2 restart

Starting Tacker server

1).Open a new console and launch tacker-server. A separate terminal is required because the console will be locked by a running process.

Note

The path of tacker-server varies according to the operating system, e.g. it is /usr/bin/tacker-server for CentOS

sudo python /usr/local/bin/tacker-server \
    --config-file /usr/local/etc/tacker/tacker.conf \
    --log-file /var/log/tacker/tacker.log

Starting Tacker conductor

1).Open a new console and launch tacker-conductor. A separate terminal is required because the console will be locked by a running process.

Note

The path of tacker-conductor varies according to the operating system, e.g. it is /usr/bin/tacker-conductor for CentOS

sudo python /usr/local/bin/tacker-conductor \
    --config-file /usr/local/etc/tacker/tacker.conf \
    --log-file /var/log/tacker/tacker-conductor.log
