ansible

他是基于模块工作的，本身没有批量部署的能力。

真正具有批量部署的是ansible所运行的模块，ansible只是提供一种框架。

格式

ansible  主机ip| 域名|组名|别名  -m  ping|copy|...  '参数'

--ping模块

# 查看有没有安装epel

# yum list installed|grep epel

# 安装ansible

# yum -y install ansible

# 查看ansible的版本

# ansible --version

查找ansible的配置文件

# find /etc/ -name "*ansible*"
/etc/ansible
/etc/ansible/ansible.cfg
设置免密

# ssh-keygen

#  ls ./.ssh/
id_rsa  id_rsa.pub

给s0和s1设置免密登录

# ssh-copy-id -i 192.168.1.17
# ssh-copy-id -i 192.168.1.18
# vim /etc/ansible/hosts
[group01] 
192.168.1.17
192.168.1.18

ping  group01的IP

[root@bb ~]# ansible 192.168.1.17 -m ping
192.168.1.17 | SUCCESS => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": false, "ping": "pong"
}
[root@bb ~]# ansible group01 -m ping
192.168.1.17 | SUCCESS => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": false, "ping": "pong"
}
192.168.1.18 | SUCCESS => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": false, "ping": "pong"
}

--hostname模块

--file模块

在group01中的主机的 /tmp/中创建abc文件

-m  表示调用模块

state=directory表示当前的状态被设置为“目录”

[root@bb ~]#  ansible group01 -m file -a 'path=/tmp/abc state=directory'
