Ansible之playbook自動完成硬盤分區，格式化，掛盤，並遠程建立用戶

前言

對於剛剛拿到拿到的新機器，惟一的可用信息有，IP地址，服務器登錄用戶名和密碼。

通常狀況，root用戶是不能直接登錄，只能經過普通用戶跳轉。

特別是最近工做中遇到的騰訊雲服務器，申請以後硬盤都尚未掛載上去，還須要手動掛載操做，這個是比較費事的。因此這裏採用ansible中的playbook將以上的工做都一併完成

playbook

如下的playbook功能包括：

1. 分區新掛載硬盤，默認是一個分區所有使用

2. 格式化新掛載分區

3. mount新分區

4. 建立遠程管理用戶

5. 下發ssh公鑰，爲之後ansible遠程管理作準備

自動化分區腳本(disk.sh)

#!/bin/bash

DISK=$1

CHECK_EXIST=`/sbin/fdisk -l 2> /dev/null | grep -o "$DISK"`
[ ! "$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;}

echo "2" > /tmp/disk.log

/sbin/fdisk /dev/sdb<<EOF
