Ansible

安装

centos

yum -y install epel-release
yum list all *ansible*
yum info ansible
yum -y install ansible

配置文件

/etc/ansible/ansible.cfg    主配置文件
/etc/ansible/hosts          Inventory
/usr/bin/ansible-doc        帮助文件
/usr/bin/ansible-playbook   指定运行任务文件

定义Inventory

# cd /etc/ansible/
# cp hosts{,.bak}
# > hosts

# cat hosts
[webserver]
127.0.0.1
192.168.10.149

[dbserver]
192.168.10.113

跳过SSH 认证

What you can do at the inventory level is add

ansible_ssh_common_args='-o StrictHostKeyChecking=no'

ansible_ssh_extra_args='-o StrictHostKeyChecking=no'

to your host definition (see Ansible Behavioral Inventory Parameters).

This will work provided you use the ssh connection type, not paramiko or something else).

For example, a Vagrant host definition would look like…

vagrant ansible_port=2222 ansible_host=127.0.0.1 ansible_ssh_common_args='-o StrictHostKeyChecking=no'

vagrant ansible_port=2222 ansible_host=127.0.0.1 ansible_ssh_extra_args='-o StrictHostKeyChecking=no'

使用秘钥方式连接

ssh-keygen -t rsa 
ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.10.149
ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.10.113
ssh-copy-id -i /root/.ssh/id_rsa.pub root@127.0.0.1

使用帮助

ansible-doc -l                列出ansible所有的模块
ansible-doc -s MODULE_NAME    查看指定模块具体适用

Ansible命令

Syntax

ansible <host-pattern> [-f forks] [-m module_name] [-a args]

<host-pattern>  这次命令对哪些主机生效的
   inventory group name

   all
-f forks        一次处理多少个主机
-m module_name  要使用的模块
-a args         模块特有的参数

ansible 192.168.10.113 -m command -a 'date'
ansible webserver -m command -a 'date'
