2.2、自动磁盘挂载

自动磁盘挂载

在项目初期给到服务器后，或中途空间不足，会出现磁盘扩容，这个时候就需要进行磁盘的挂载。这里推荐宝塔自动磁盘挂载工具。

• 1、本工具默认将数据盘挂载到/www目录
• 2、若您的服务器之前安装过Windows系统，需要手动删除NTFS分区，挂载工具会直接跳过NTFS分区
• 3、若您的磁盘已分区，且未挂载，工具会自动将分区挂载到/www
• 4、若您的磁盘是新磁盘，工具会自动分区并格式化成ext4文件系统
• 5、本工具只自动挂载一个分区，若您有多块数据盘，请手动挂载未被自动挂载的磁盘
• 6、此脚本只适用于新磁盘挂载，若数据盘已有数据请勿使用此脚本

在线操作

yum install wget -y && wget -O auto_disk.sh http://download.bt.cn/tools/auto_disk.sh && bash auto_disk.sh

离线操作

如果你的主机没有外网，可以在有网络的电脑上下载 auto_disk.sh， 然后上传到你的目标主机

chmod -R 755 auto_disk.sh
bash auto_disk.sh

如果你不想挂载在 www 目录，可以手动修改脚步内容：

#!/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=/www
#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,无法挂载"
    echo -e "Bye-bye"
    exit;
fi
#检测/www目录是否已挂载磁盘
mountDisk=`df -h | awk '{print $6}' |grep www`
if [ "${mountDisk}" != "" ]; then
    echo -e "www directory has been mounted,exit"
    echo -e "www目录已被挂载,不执行任何操作"
    echo -e "Bye-bye"
    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
