客户有一个新的磁盘需要挂载到服务器，作为数据盘是非常重要的。服务器基于宝塔搭建的一个管理端，腾讯服务器自动挂载到了服务器（没有实际mount），在宝塔没有显示数据盘，只有50G的系统盘，这时候需要用mount 命令挂载磁盘，当然用宝塔的脚本更方便，可以转移数据到新的磁盘。
命令（centos系统）：
yum install wget -y && wget -O auto_disk.sh http://download.bt.cn/tools/auto_disk.sh && bash auto_disk.sh
上面的命令可以自动挂载并迁移数据到数据盘哦。
操作过程：
yum install wget -y && wget -O auto_disk.sh http://download.bt.cn/tools/auto_disk.sh && bash auto_disk.sh
#这里省略下载执行过程
#确认是否要挂载到这个目录下面

宝塔也显示了数据盘：
提示：如果想要挂载到其他盘的可以修改auto_disk.sh里开始的setup_path变量值:
#!/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 #这个可以修改挂载位置哦
