Unfortunately connmon hasn't been used in a while and isn't well tested on latest releases, thus ideally in order to prevent any more cruft issues, lets remove it for now and if it becomes relevant again we can add it back in. Change-Id: I0759d164621f3aac1c36dbe1fac49acd7dde97e3

Getting Started
|
|
---------------
|
|
|
|
Install your public key into stack's authorized\_keys
|
|
|
|
::
|
|
|
|
# ssh-copy-id stack@<undercloud-ip>
|
|
|
|
Then run generate\_tripleo\_hosts.sh script to generate your overcloud's
|
|
hosts file for ansible and generate a "jumpbox" ssh config:
|
|
|
|
::
|
|
|
|
# ./generate_tripleo_hostfile.sh <undercloud-ip> ~/.ssh/config
|
|
|
|
Review the hosts file the script generates.
|
|
|
|
Ansible Installers
|
|
------------------
|
|
|
|
Install Browbeat
|
|
''''''''''''''''
|
|
|
|
Image upload requires Ansible 2.0
|
|
|
|
::
|
|
|
|
# vi install/group_vars/all.yml
|
|
|
|
Edit ansible vars file (Installation parameters)
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts install/browbeat.yml
|
|
|
|
Install Collectd Agent (Requires a Graphite Server)
|
|
'''''''''''''''''''''''''''''''''''''''''''''''''''
|
|
|
|
Prior to installing the agent, please review install/group\_vars/all.yml
|
|
file to ensure the correct parameters are passed.
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts install/collectd-openstack.yml
|
|
|
|
To install collectd on everything other than Openstack machines, view
|
|
the `README for collectd-generic <README.collectd-generic.md>`__.
|
|
|
|
Install Kibana Visuals
|
|
''''''''''''''''''''''
|
|
|
|
Prior to installing the Kibana visuals, please review install/group\_vars/all.yml
|
|
file to ensure the correct parameters are passed.
|
|
|
|
::
|
|
browbeat_path - Point to the browbeat directory, default is /home/stack/browbeat
|
|
es_ip - Point to the ElasticSerach host, default is blank
|
|
es_kibana_index - Point to the correct Kibana index, default is .kibana
|
|
|
|
To Install Kibana Visuals
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts install/kibana-visuals.yml
|
|
|
|
Install Generic ELK Stack
|
|
'''''''''''''''''''''''''
|
|
Listening ports and other options can be changed in ``install/group_vars/all.yml``
|
|
as needed. You can also change the logging backend to use fluentd via the
|
|
``logging_backend:`` variable. For most uses leaving the defaults in place is
|
|
accceptable. If left unchanged the default is to use logstash.
|
|
|
|
You can also install the optional `curator <https://www.elastic.co/guide/en/elasticsearch/client/curator/current/index.html>`_ tool for managing
|
|
elasticsearch indexes. Set ``install_curator_tool: true`` to enable this optional tool installation.
|
|
|
|
If all the variables look ok in ``install/group_vars/all.yml`` you can proceed with deployment.
|
|
|
|
::
|
|
|
|
ansible-playbook -i hosts install/elk.yml
|
|
|
|
Install ELK Stack (on an OpenStack Undercloud)
|
|
''''''''''''''''''''''''''''''''''''''''''''''
|
|
Triple-O based OpenStack deployments have a lot of ports already listening on
|
|
the Undercloud node. You'll need to change the default listening ports for ELK
|
|
to be deployed without conflict.
|
|
|
|
::
|
|
|
|
sed -i 's/nginx_kibana_port: 80/nginx_kibana_port: 8888/' install/group_vars/all.yml
|
|
sed -i 's/elk_server_ssl_cert_port: 8080/elk_server_ssl_cert_port: 9999/' install/group_vars/all.yml
|
|
|
|
Now you can proceed with deployment.
|
|
|
|
::
|
|
|
|
ansible-playbook -i hosts install/elk.yml
|
|
|
|
Install Generic ELK Clients
|
|
'''''''''''''''''''''''''''
|
|
Filebeat (official Logstash forwarder) is used here unless you chose the
|
|
optional fluentd ``logging_backend`` option in ``install/group_vars/all.yml``. In this case
|
|
a simple rsyslog setup will be implemented.
|
|
|
|
::
|
|
|
|
ansible-playbook -i hosts install/elk-client.yml --extra-vars 'elk_server=X.X.X.X'
|
|
|
|
The ``elk_server`` variable will be generated after the ELK stack playbook runs,
|
|
but it's generally wherever you installed ELK. If you have an existing ELK
|
|
stack you can point new clients to it as well, but you'll want to place a new
|
|
client SSL certificate at the location of
|
|
``http://{{elk_server}}:{{elk_server_ssl_cert_port}}/filebeat-forwarder.crt``
|
|
|
|
Install ELK Clients for OpenStack nodes
|
|
'''''''''''''''''''''''''''''''''''''''
|
|
|
|
::
|
|
|
|
ansible-playbook -i hosts install/elk-openstack-client.yml --extra-vars 'elk_server=X.X.X.X'
|
|
|
|
Install graphite service
|
|
''''''''''''''''''''''''
|
|
|
|
When installing graphite, carbon-cache and grafana on a
|
|
director/rdo-manager undecloud host, Use the docker playbook instead of
|
|
this one. This playbook is intended for use when you have enough
|
|
resources to allocate dedicated systems for the graphing/stats related
|
|
services. Prior to installing grafana, please review
|
|
install/group\_vars/all.yml file and your ansible inventory file You
|
|
will need to define values for the grafana\_host and graphite\_host IP
|
|
addresses here. Optionally you can change the listening port for
|
|
graphite-web.
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts install/graphite.yml
|
|
|
|
Install graphite service as a docker container
|
|
''''''''''''''''''''''''''''''''''''''''''''''
|
|
|
|
Prior to installing graphite as a docker container, please review
|
|
install/group\_vars/all.yml file and ensure the docker related settings
|
|
will work with your target host. This playbook is ideal when installing
|
|
services on director/rdo-manager undercloud host(s).
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts install/graphite-docker.yml
|

|
dashboards
|
|
|
|

|
|
# ansible-playbook -i hosts install/dashboards-openstack.yml
|
|
|
|
Gather Metadata
|
|
---------------
|
|
|
|
Run the gather playbook to gather metadata about how the OpenStack cloud is
|
|
currently configured. This playbook writes hardware(No. of CPUs etc),
|
|
software(OpenStack Configuration), environment(No. of controllers etc) metadata
|
|
files into the metadata directory which are transported to ElasticSearch along
|
|
with test results to provide context for the result data.
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts gather/site.yml
|
|
|
|
|
|
|
|
Performance Check
|
|
-----------------
|
|
|
|
Run the check playbook to identify common performance issues:
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts check/site.yml
|
|
|
|
Performance Tune
|
|
----------------
|
|
|
|
Run the tune playbook to tune your OSPd deployed cloud for performance:
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts tune/tune.yml
|
|
|
|
Adjust your overcloud
|
|
---------------------
|
|
|
|
To modify the number of workers each service is running:
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8"
|
|
|
|
Openstack services will be running 8 workers per service.
|
|
|
|
To modify number of workers each service is running and ensure Keystone
|
|
is deployed in eventlet:
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8 keystone_deployment=eventlet"
|
|
|
|
To run Keystone in httpd, change keystone\_deployment to httpd:
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts browbeat/adjustment-workers.yml -e "workers=8 keystone_deployment=httpd"
|
|
|
|
To switch to fernet tokens:
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts browbeat/adjustment-keystone-token.yml -e "token_provider=fernet"
|
|
|
|
To switch to UUID tokens:
|
|
|
|
::
|
|
|
|
# ansible-playbook -i hosts browbeat/adjustment-keystone-token.yml -e "token_provider=uuid"
