| 5 | 3 | Irene Meisel | This page will cover some helpful one-line commands we can execute with Ansible to accomplish various tasks. Always run **git pull** and **git submodule update** before executing these commands. |

| 7 | 6 | Jon Goldberg | ### Synchronize a non-canonical site with the live site's database |
| 8 | 2 | Jon Goldberg | ``` |
| 9 | 1 | Jon Goldberg | ansible-playbook main-playbook.yml --tags site-db-sync -l mysite.local |
| 10 | 2 | Jon Goldberg | ``` |
| 11 | 6 | Jon Goldberg | * This works on test and dev sites. |
| 12 | * Depending on the sync strategy on the website inventory, it will pull from last night's backup, sync directly from the live site, or use the Pantheon API to make a backup/download. |
||
| 13 | 1 | Jon Goldberg | * Only sites that pull from backup can sync to a site that's not on your local machine at present (I'll fix this at some point). |

| 15 | 6 | Jon Goldberg | ### Ad-hoc examples |
| 16 | 1 | Jon Goldberg | #### Revert a failed local update |
| 17 | ```shell |
||
| 18 | ansible '*.local' -m shell -a "cd {{webroot}} && git checkout ." --become --become-user "{{ run_as_user }}" |
||
| 19 | ``` |
||
| 20 | 4 | Jon Goldberg | |
| 21 | 6 | Jon Goldberg | #### Roll back a site to the latest commit (e.g. after a failed merge): |
| 22 | ```shell |
||
| 23 | ansible --become -m shell -a 'cd {{civiroot}} && git clean -fdx {{civiroot}} && get reset --hard HEAD' mysite1.local,mysite2.local |
||
| 24 | ``` |
||
| 25 | |||
| 26 | 7 | Jon Goldberg | #### Send a drush command to multiple sites |
| 27 | This is trickier to handle places where we don't have root, but works. |
||
| 28 | ```shell |
||
| 29 | ansible --become --become-user="{{ run_as_user }}" -m shell -a "PATH=\$HOME/bin:\$PATH; drush --root={{ webroot }} pm-disable -y print" 'maintenance_drupal' |
||
| 30 | ``` |
||
| 31 | |||
| 32 | 1 | Jon Goldberg | #### Send an arbitrary SQL statement to all Civi test instances with maintenance contracts |
| 33 | ```shell |
||
| 34 | 4 | Jon Goldberg | ansible --become --become-user="{{ run_as_user }}" -m shell -a "PATH=\$HOME/bin:\$PATH; echo \"UPDATE civicrm_job SET is_active = 0 WHERE api_action = 'group_rebuild';\" | cv --cwd={{ webroot }} sql" 'maintenance_civi:&websites_test' |
| 35 | ```` |
||
| 36 | 6 | Jon Goldberg | |
| 37 | #### Set CLI PHP version across all servers |
||
| 38 | This is an example of server-level changes (others are site-level). |
||
| 39 | ```shell |
||
| 40 | ansible --become -m command -a 'update-alternatives --set php /usr/bin/php7.4' vps |
||
| 41 | ``` |
