腾讯云服务器挂载云硬盘

1、到腾讯云服务器购买一块云硬盘，然后直接挂载到你的服务器下就可以了，如果服务器不能识别，请看部分存量云服务器无法识别弹性云盘的解决方法

2、挂载完云硬盘之后，云硬盘默认处于未加载状态，使用df -h指令可以看见服务器中硬盘的加载状况，如下：

ubuntu@VM-164-254-ubuntu:/$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            414M     0  414M   0% /dev
tmpfs            87M  9.4M   78M  11% /run
/dev/vda1        20G  4.5G   15G  24% /
tmpfs           433M   48K  433M   1% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           433M     0  433M   0% /sys/fs/cgroup
tmpfs            87M     0   87M   0% /run/user/500
ubuntu@VM-164-254-ubuntu:/$ cd etc/

，没有相关硬盘信息，使用fdisk -l查看所有硬盘信息：

ubuntu@VM-164-254-ubuntu:/$ sudo fdisk -l

根据最后一段disk可以看到事这块30G的硬盘没有加载，所以接下来使用

$腾讯云服务器挂载云硬盘_ubuntu$

进行磁盘分区：

ubuntu@VM-164-254-ubuntu:/$ sudo fdisk /dev/vdb

Welcome to fdisk (util-linux 2.27.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

分区完成之后，进行挂载，首先创建一个待挂载的目录：

ubuntu@VM-164-254-ubuntu:/var/www/html/test/adminweb$ mkdir tuijian

挂载分区有两种办法：
1、直接使用mount指令：

ubuntu@VM-164-254-ubuntu:/var/www/html/test/adminweb$ sudo mount /dev/vdb1 ./tuijian

2、写入到/dev/fstab文件中，操作系统开机启动时会检查这个文件并自动加载

vi /dev/fstab
/dev/vdb1            /var/www/html/test/adminweb/tuijian exy3 defaults     0 0

保存之后就行了，使用
