• ansible 2.8.5

• inventory/hosts
• inventory/group_vars/all/all.yml

ansible-playbook -i inventory/hosts playbooks/site.yml

ansible-playbook -i inventory/hosts playbooks/site.yml --tags "status"

在同一套环境里面部署多次的话，可以先清理集群

ansible-playbook -i inventory/hosts playbooks/clean.yml

ansible-playbook -i inventory/hosts playbooks/kernel.yml
