騰訊雲伺服器挂載雲硬碟
1、到騰訊雲伺服器購買一塊雲硬碟，然後直接挂載到你的伺服器下就可以了，如果伺服器不能識别，請看部分存量雲伺服器無法識别彈性雲盤的解決方法
2、挂載完雲硬碟之後，雲硬碟預設處于未加載狀态，使用df -h指令可以看見伺服器中硬碟的加載狀況，如下：

ubuntu@VM-164-254-ubuntu:/$ 分區完成之後，進行挂載，首先建立一個待挂載的目錄：
ubuntu@VM-164-254-ubuntu:/var/www/html/test/adminweb$ mkdir tuijian 挂載分區有兩種辦法：
1、直接使用mount指令：
ubuntu@VM-164-254-ubuntu:/var/www/html/test/adminweb$ sudo mount /dev/vdb1 ./tuijian 2、寫入到/dev/fstab檔案中，作業系統開機啟動時會檢查這個檔案并自動加載
vi /dev/fstab
/dev/vdb1 /var/www/html/test/adminweb/tuijian exy3 defaults 0 0 儲存之後就行了，使用
檢視：
