#查看内存

ansible webservers -a "free -m"

#基本配置

vim /etc/ansible/ansible.cfg

[defaults]

inventory = /etc/ansible/hosts
forks = 5
sudo_user = root
remote_port = 22
host_key_checking = False
timeout = 10
log_path = /var/log/ansible.log
private_key_file = /root/.ssh/id_rsa

Inventory 主机清单

/etc/ansible/hosts 中默认给提供了三种模板

Ex1：未分组的主机，默认在all组中。

ansible all -a "free -m"

Ex2：属于webservers的主机组。

ansible webservers -a "free -m"

主机名称有规律可以使用范围配置

Ex3：属于dbservers的主机组。
