Ansible-playbook服务器初始化

一、什么是Playbook

playbook可以理解为ansible的shell脚本，它是一个编排工具，作用是使用编排出能够重复利用的ansible脚本，并并发处理多台服务器。

二、playbook使用事件

1.服务器初始化

（1）playbook的task任务

#本脚本用来进行Centos7系统初始化，请谨慎使用

[ ! "$CHECK_EXIST" ] && { echo "Error: Disk is not found !"; exit 1;}

echo "1" > /tmp/disk.log

CHECK_DISK_EXIST=`/sbin/fdisk -l 2> /dev/null | grep -o "$DISK[1-9]"`
[ ! "$CHECK_DISK_EXIST" ] || { echo "WARNING: ${CHECK_DISK_EXIST} is Partition already !"; exit 1;}

/sbin/fdisk /dev/sdb<<EOF
d
n
p

w

（3）执行的sysinit.yml

- hosts: sysinit
  vars:
    disk: /dev/vdb
    partition: /dev/vdb1

     - sysinit

（4）inventory文件
