@xiaoqiang2209 Hi. It seems that there's no deployment_method in yourtidb-ansible/inventory.ini file. See inventory.ini .

Hi, what's your ansible version? You can install it by following commands and try again.

yum install epel-release
yum install ansible

@xiaoqiang2209 You need install Ansible 2.4.2 or later to your platform. See https://github.com/pingcap/docs/blob/master/op-guide/ansible-deployment.md#install-ansible-in-the-control-machine. Please uninstall your ansible package and install ansible from epel repo again.
