8.16-ansible的应用

ansible

ansible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。

主机清单的作用：服务器分组

主机清单的常见功能：

1.可以通过IP范围来分，主机名名字的范围来分

2.如果ssh端口不是22的，可以传入新的端口

3.没有做免密登录，可以传密码

练习

不论你用到哪种环境（免密或者不免密，端口是否是22），请最终将两台被管理机器加入到group1组即可

# 没有设置免密的话需要设置别名
web01 ansible_ssh_host=192.168.2.200 ansible_ssh_user=root ansible_ssh_pass=1 ansible_ssh_port=22
web01 ansible_ssh_host=192.168.2.201 ansible_ssh_user=root ansible_ssh_pass=1 ansible_ssh_port=22

backup参数小结：

使用backup参数控制是否备份文件

backup=yes表示如果拷贝的文件内容与原内容不一样，则会备份一份/tmp/3333（备份文件名加上时间）文件，再拷贝新的文件/tmp/333

master# ansible group01 -m  copy -a 'src=/etc/fstab dest=/tmp/333 backup=yes owner=daemon group=daemon'

6.fetch模块
