#挂载 ，提前建好挂在目录，这句诗挂载sdc设备的第五个分区
mount /dev/sdc5  /mnt/udisk
# 挂载ntfs的系统需要先安装ntfs-3g
yum install ntfs-3g
# 查看是否挂载成功
df -h

腾讯云初始化和挂载硬盘

  1. fdisk -l查看磁盘, 如果没有输出硬盘检查云盘状态是否已挂载

    Disk /dev/vdb: 107.4 GB, 107374182400 bytes, 209715200 sectors

  2. fdisk /dev/vdb创建新分区依次输入“n”(新建分区)、“p”(新建主分区)、“1”(使用第1个主分区)，两次回车(使用默认配置)，输入“wq”(保存分区表)

  4. mkdir /data如果没有创建挂载目录

  5. mkfs.ext3 /dev/vdb1 格式化硬盘

  6. mount /dev/vdb1 /data设置挂载

  7. vim /etc/fstab设置开机启动自动挂载，fstab追加行

    /dev/vdb1            /data                ext3       defaults              0 0
