In peacetime operation and maintenance work sometimes need to be based on different remote nodes or different IP systems to do different configuration deployment. For example, ansible can do different processing of the configuration files on each node according to different IP addresses, and variables are needed here.You can define variables directly in the playbooks file:-Hosts:webservers vars:http_port:80A variable named Http_port is defined with a
