如何在ansible中，使用不同的用户登录不同的主机？
#在hosts文件中为每个主机单独设置：
# hosts
[webservers]
web1.example.com ansible_user=admin
web2.example.com ansible_user=deploy[databases]
db1.example.com ansible_user=dba
db2.example.com ansible_user=root[all:vars]
ansible_ssh_private_key_file=~/.ssh/id_rsa
实际应用场景
- hosts: webserverstasks:- name: restart web serviceservice:name: nginxstate: restarted# web1: admin执行, web2: deploy执行- hosts: databases tasks:- name: optimize databasemysql_query:query: "OPTIMIZE TABLE important_data;"# db1: dba执行, db2: root执行
