Ubuntu开机自动挂载分区

首先，查看系统的磁盘代号：fdisk -lDisk /dev/sda: 120.0 GB, 120034123776 bytes255 heads, 63 sectors/track, 14593 cylinders, total 234441648 sectorsUnits = 扇区 of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x000214d1 设备启动起点终点块数 Id 系统/dev/sda1 * 2048 217925631 108961792 83 Linux/dev/sda2 217927678 234440703 8256513 5 扩展/dev/sda5 217927680 234440703 8256512 82 Linux 交换 / SolarisDisk /dev/sdb: 500.1 GB, 500107862016 bytes255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectorsUnits = 扇区 of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 4096 bytesI/O size (minimum/optimal): 4096 bytes / 4096 bytesDisk identifier: 0xec689ddc 设备启动起点终点块数 Id 系统/dev/sdb1 2052 471040703 235519326 7 HPFS/NTFS/exFAT分区 1 未起始于物理扇区边界。/dev/sdb2 471040704 976770467 252864882 7 HPFS/NTFS/exFATDisk /dev/sdc: 8178 MB, 8178892800 bytes92 heads, 57 sectors/track, 3046 cylinders, total 15974400 sectorsUnits = 扇区 of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x16c0ca45 设备启动起点终点块数 Id 系统/dev/sdc1 * 1552 15974399 7986424 b W95 FAT32注意：根目录/一定要先于其他目录被挂载起来。其他的挂载点必须为已创建好的目录。使用如下命令查看其他磁盘的UUID：sudo blkid结果如下：/dev/sda1: UUID="70fb376c-17c2-4ce1-a263-727f647949cf" TYPE="ext4" /dev/sda5: UUID="0c5f073a-ad3f-414f-85c2-4af83f6a437f" TYPE="swap" /dev/sdb1: UUID="11263962-9715-473f-9421-0b604e895aaa" TYPE="ext4" /dev/sdb2: UUID="88928fea-5dd3-47b1-9931-bb107d74371e" TYPE="ext4"接下来修改自动挂载的配置文件：sudo vim /etc/fstab修改如下：UUID=70fb376c-17c2-4ce1-a263-727f647949cf / ext4 errors=remount-ro 0 1# swap was on /dev/sda5 during installationUUID=0c5f073a-ad3f-414f-85c2-4af83f6a437f none swap sw 0 0UUID=11263962-9715-473f-9421-0b604e895aaa /data ext4 defaults 0 1UUID=88928fea-5dd3-47b1-9931-bb107d74371e /export ext4 defaults 0 1最后两行为新加的挂载点。注意，千万不要将挂载目录设置为/，否在会覆盖原有的根目录，系统就会挂掉。
