ansible基础配置示例

一、创建inventory文件

mkdir /home/greg/ansible
vim /home/greg/ansible/inventory

inventory文件内容

node1
node2
node3
node4
node5
[dev]
node1
[test]
node2
[prod]
node3
node4
[balancers]
node5
[webservers:children]
prod

二、ansible的配置文件ansible.cfg

vim /home/greg/ansible/ansible.cfg

[defaults]
inventory = /home/greg/ansible/inventory
roles_path = /home/greg/ansible/roles
remote_user = greg
ask_pass = false

[privilege_escalation]
become = true
become_method = sudo
become_user = root
become_ask_pass = false

三、如果没有免密登录

在inventory所在目录穿件文件夹

mkdir group_vars
vim all

#
ansible_ssh_pass: redhat
