Linux 开机自动装载硬盘

首先用blkid来查看一下硬盘的UUID

blkid
/dev/sda1: UUID="be32db7c-f4a1-4143-816d-351fec7681f4" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="a5874101-01"
/dev/sda2: UUID="4c73f462-4ae1-466a-9976-686b122bd72e" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="a5874101-02"
/dev/sda3: UUID="27b5b97e-4e28-4b59-9094-93eb8baafc17" TYPE="swap" PARTUUID="a5874101-03"
/dev/sda5: UUID="2f0446a8-2e2b-4a29-8c8e-a8f24f9a6943" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="a5874101-05"
/dev/sdb1: UUID="5cce7d74-6386-4e6a-b61c-352f224263c4" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="74f5b0c6-3cef-b547-98e0-6a091d737799"

我们要自动挂载sdb1

vim /etc/fstab

#
# /etc/fstab
# Created by anaconda on Sun Dec 20 19:43:57 2020
#
# Accessible filesystems, by reference, are maintained under '/dev/disk/'.

UUID=4c73f462-4ae1-466a-9976-686b122bd72e /                       xfs     defaults        0 0
UUID=be32db7c-f4a1-4143-816d-351fec7681f4 /boot                   ext4    defaults        1 2
UUID=2f0446a8-2e2b-4a29-8c8e-a8f24f9a6943 /home                   xfs     defaults        0 0
UUID=27b5b97e-4e28-4b59-9094-93eb8baafc17 swap                    swap    defaults        0 0

输入i开始编辑 箭头可移动光标位置

在下一行添加以下代码即可 /smb是挂载目录（目录必须已经存在）

（谨慎使用自动挂载，一旦设置错误则无法正常开机）

UUID=5cce7d74-6386-4e6a-b61c-352f224263c4 /smb                    ext4    defaults        0 0

按一下esc 输入:wq (保存退出) 就OK了
