Ubuntu系统挂载磁盘硬盘

在电脑（Ubuntu16.04）新装了一个硬盘，然后只有挂载了我们才能正常使用，下面总结一下挂载的过程。

首先，打开命令行输入命令：

sudo fdisk -l

可以看到：磁盘格式化后

硬盘格式化

命令：sudo mkfs -t ext4 /dev/sda 
说明一下：-t ext4表示将分区格式化为ext4文件系统类型

sudo blkid 这个能显示每个磁盘的UUID

uxsrt@ubuntu-algserver:/data1$ sudo blkid
/dev/sda1: UUID="028b5062-e9d0-42af-be08-c3be080a0b7e" TYPE="ext4" PARTUUID="1ce07b8d-01"
/dev/sda5: UUID="bafd3244-6eb9-4bdb-bbee-8f6c0e293927" TYPE="swap" PARTUUID="1ce07b8d-05"
/dev/sdb: UUID="eded7b1d-65fb-49c1-81b1-73cc44309821" TYPE="ext4"
/dev/sdc: UUID="e624b217-4b2e-409a-8f27-4b6b67ec9132" TYPE="ext4"
/dev/sdd: UUID="454fa7d1-54f3-4be4-bd6d-e31d34934985" TYPE="ext4"

sudo vim /etc/fstab
