一个磁盘挂载的shell脚本

每次linux服务器在分配了新的磁盘之后就需要手动去挂载一下,用命令行操作不是很方便,而且操作不当会导致服务器开不了机的严重后果,所以我根据实际的需要修改个编写了一个磁盘挂在的脚本,目前测试没有太大问题,希望可以帮助到有需要的同学们

#!/bin/bash
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
export PATH
LANG=en_US.UTF-8
setup_path=/deya
#if [ $1 != “” ];then
#setup_path=$1;
#fi

#检测磁盘数量
sysDisk=`cat /proc/partitions|grep -v name|grep -v ram|awk ‘{print $4}’|grep -v ‘^$’|grep -v ‘[0-9]$’|grep -v ‘vda’|grep -v ‘xvda’|grep -v ‘sda’|grep -e ‘vd’ -e ‘sd’ -e ‘xvd’`
if [ “${sysDisk}” == “” ]; then
echo -e “ERROR!This server has only one hard drive,exit”
echo -e “此服务器只有一块磁盘,我挂不了”
echo -e “告辞”
exit;
fi
#检测指定目录是否已挂载磁盘
mountDisk=`df -h | awk ‘{print $6}’ |grep deya`
if [ “${mountDisk}” != “” ]; then
echo -e “target directory has been mounted,exit”
echo -e “指定目录已被挂载,不执行任何操作”
echo -e “告辞”
exit;
fi
#检测是否有windows分区
winDisk=`fdisk -l |grep “NTFS\|FAT32″`
if [ “${winDisk}” != “” ];then
echo ‘Warning: The Windows partition was detected. For your data security, Mount manually.’;
echo “危险 数据盘为windwos分区,为了你的数据安全,请手动挂载,本脚本不执行任何操作。”
exit;
fi
echo “

sed -i “/\/dev\/${i}1/d” /etc/fstab
mount -a
df -h
else
rm -f $setup_path/checkD.pl
fi
fi
done
}

while [ “$go” != ‘y’ ] && [ “$go” != ‘n’ ]
do
read -p “Do you want to try to mount the data disk to the $setup_path directory?(y/n): ” go;
done

if [ “$go” = ‘n’ ];then
echo -e “告辞!”
exit;
fi

#执行挂载操作
fdiskP
echo -e “”
echo -e “Done”
echo -e “挂载成功”

将上面的脚本保存成一个文件,赋予一个执行的权限,即可自动挂载磁盘到我们设置好的目录下
