# Ansible for Browbeat
|
|
Playbooks to modify and performance check the overcloud
|
|
|
|
## 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.
|
|
|
|
To modify the number of workers each service is running:
|
|
|
|
```
|
|
# ansible-playbook -i hosts browbeat/adjustment.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.yml -e "workers=8 keystone_deployment=eventlet"
|
|
```
|
|
|
|
To run Keystone in httpd, change keystone_deployment to httpd:
|
|
|
|
```
|
|
# ansible-playbook -i hosts browbeat/adjustment.yml -e "workers=8 keystone_deployment=httpd"
|
|
```
|
|
|
|
## Performance Checks:
|
|
|
|
Run the check playbook to identify common performance issues:
|
|
|
|
```
|
|
# ansible-playbook -i hosts check/site.yml
|
|
```
|
|
|
|
## Ansible Installers:
|
|
|
|
Install connmon/shaker
|
|
|
|
```
|
|
# ansible-playbook -i hosts install/install.yml -e "connmon=true"
|
|
# ansible-playbook -i hosts install/install.yml -e "shaker=true"
|
|
# ansible-playbook -i hosts install/install.yml -e "connmon=true shaker=true"
|
