Linux Learning-disk partitioning + boot auto mount

Looking at the bird Brother Linux private dishes, found a lot of interesting things, really brief encounter.

Situation: Create a new filesystem hanging in the/srv/myproject directory, and let it automatically mount to the directory, the directory for Project group sharing, no other people have any permissions, capacity 5G

Goal: Understand file system build, automatic mount, permission assignment

The process is as follows:

1. Create a partition using FDISK/DEV/SDA, create a new partition according to the English prompts, and save the last W

2. Restart

3. Format: Mkfs-t Ext3/dev/sda6 Sda6 is the new partition.

4. Set up a mount point: mkdir/srv/myproject

5. Edit the Automatically mounted profile: Vi/etc/fstab

New line:/dev/sda6/srv/myproject ext3 defaults 1 2

One, two or three items do not explain, four is a string set of things

• Auto: The system mounts automatically, Fstab is this option by default
• DEFAULTS:RW, suid, Dev, exec, auto, Nouser, and async.
• Noauto boot does not mount automatically
• Nouser only super users can mount
• RO mount by read-only permission
• RW mount by Read writable permission
• User can mount
• Please note that the optical drive and floppy drive can only be mounted when the media is installed, so it is Noauto

Five items indicate dump backup settings, 1 o'clock will allow dump program backup, 0 when the backup operation is ignored

The six items are the fsck disk check setting, which is a numeric value that represents the order, 0 o'clock never check,/the root directory is always 1, the other partitions start from 2, the smaller the first check, the same simultaneously check

6. Test an automatic mount: mount-a use DF to see

7. Set permissions: Chgrp project/srv/myproject; chmod 2770/srv/myproject
