[脚本]为所有节点挂载磁盘

1. 循环遍历所有节点

#!/bin/bash

IpPrefix=192.168.1.
User=root
Pwd=000000

for((i=84;i<148;i++))
do
{
        ./remote.exp $IpPrefix$i $User $Pwd  >> tmp/$i
        echo "$i done!"
}&
done

2. 拷贝文件到所有节点

#!/usr/local/bin/expect -f

set timeout -1

set IpAddr [lindex $argv 0]
set User [lindex $argv 1]
set Pwd [lindex $argv 2]

spawn ssh [email protected]$IpAddr "cd /home/; rm -rf packages/; mkdir packages"
expect  {
        "yes/no" { send "yes\n"; expect "*assword:" { send "$Pwd\n" } }
        "*assword:*" { send "$Pwd\n"; }
}
expect eof

spawn scp -r packages [email protected]$IpAddr:/home/
expect "*assword:*" { send "$Pwd\n"; }
expect eof

spawn ssh [email protected]$IpAddr "cd /home/packages;./install.sh;"
expect "*assword:*" { send "$Pwd\n"; }
expect "*mount finished*" { send \003 }
expect eof

3. 所有节点上执行脚本

packages/install.sh

#!/bin/bash
./installExpect.sh
disk=`sh getDisk.sh`
disk="${disk//\//\\/}"
flag=`blkid | awk "/^${disk}/" | cut -d ‘"‘ -f 4`
if [ "$flag" == "ext4" ]; then
        echo "Already mkfs..."
else
        ./mkfs.exp
fi
tune2fs -c -1 -i 0 /dev/sdb
mv /home/iscas/ /home/iscas2/
mkdir /home/iscas/
UUID=`tune2fs -l /dev/sdb | awk ‘/^Filesystem UUID:/{print $3}‘`
echo -e "UUID=$UUID\t/home/iscas\text4\tdefaults\t1\t2"  >> /etc/fstab

mount -a
mv /home/iscas2/* /home/iscas/
rm -rf /home/iscas2/

echo "mount finished"

4. 获取节点最大磁盘名称

packages/getDisk.sh

#!/bin/bash
disk=`fdisk -l 2>/tmp/null | awk ‘BEGIN{Max=0} {if($0~/^Disk \//){if($3>Max){disk=$2}}} END{print disk}‘ | cut -d : -f 1`
echo $disk

5. 格式化最大磁盘

packages/mkfs.exp

#!/usr/bin/expect -f

set timeout -1
set disk [exec sh getDisk.sh]
spawn mkfs -t ext4 $disk
expect  "(y,n)" { send "y\r";}
expect eof

6. 挂载磁盘并设置属性

tune2fs -c -1 -i 0 /dev/sdb
mkdir /home/iscas/
UUID=`tune2fs -l /dev/sdb | awk ‘/^Filesystem UUID:/{print $3}‘`
echo -e "UUID=$UUID\t/home/iscas\text4\tdefaults\t1\t2"  >> /etc/fstab
mount -a
