# Ansible for Browbeat
|
|
|
|
Currently we support Ansible 1.9.4 within browbeat-venv and ansible 2.0 for installation.
|
|
|
|
Playbooks for:
|
|
* Installing Browbeat, collectd, connmon, graphite, grafana, and grafana dashboards
|
|
* Check overcloud for performance issues
|
|
* Tune overcloud for performance (Experimental)
|
|
* Adjust number of workers for cinder/keystone/neutron/nova
|
|
* Deploy keystone in eventlet/httpd
|
|
* Adjust keystone token type to UUID/Fernet
|
|
* Adjust neutron l3 agents
|
|
* Adjust nova greenlet_pool_size / max_overflow
|
|
|
|
|
|
## To use
|
|
|
|
Install your public key into stack's authorized_keys
|
|
```
|
|
# ssh-copy-id stack@<undercloud-ip>
|
|
```
|
|
|
|
Then run gen_hosts.sh script to generate your overcloud's hosts file for ansible and generate a "jumpbox" ssh config:
|
|
```
|
|
# ./gen_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 # 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 the install/group_vars/all 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 Connmon
|
|
Requires Ansible 2.0
|
|
```
|
|
# ansible-playbook -i hosts install/connmon.yml
|
|
```
|
|
|
|
##### Install graphite service
|
|
```
|
|
# ansible-playbook -i hosts install/graphite.yml
|
|
```
|
|
|
|
##### Install grafana service
|
|
Default user is admin/admin and the graphite data source will need to be defined.
|
|
```
|
|
# ansible-playbook -i hosts install/grafana.yml
|
|
```
|
|
|
|
##### Install Grafana Dashboards (Requires a Grafana Server)
|
|
Review install/group_vars/all before deploying the grafana dashboards
|
|
```
|
|
# ansible-playbook -i hosts install/dashboards.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"
|
|
```
|
|
Nova and Keystone 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/keystone_token_type.yml -e "token_provider=fernet"
|
|
```
|
|
|
|
To switch to UUID tokens:
|
|
```
|
|
# ansible-playbook -i hosts browbeat/keystone_token_type.yml -e "token_provider=uuid"
|
|
```
