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

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;}

echo "2" > /tmp/disk.log

/sbin/fdisk /dev/sdb<<EOF
d
n
p
1


t
83
w

(3)执行的sysinit.yml

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

     - sysinit

(4)inventory文件

########Init hosts list########
#[groups:children]

#ansible_user=root

[sysinit:vars]
ansible_user=root    #远程用户
ansible_port=22        #远程端口
