How to set a disk quota in Linux

Article Title: how to set a disk quota in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Purpose: to limit the number of disk space or files that a specified user (FTP user, Sambapcguest account, and Appletalk user) can own on your server.
By default, Redhat Linux has no restrictions.
Software Environment: Redhat Linux 5.2 Implementation method:
　　
1. check your/etc/fstab. assume that the file without quota is not set as follows.
/Dev/hda1/ext2 defaults 1 1
/Dev/hda2/home ext2 defaults 1 2
/Home is a separate partition.
　　
2. to set the disk space occupied by jephe in the/home/jephe Directory, first change/etc/fstab to the following:
/Dev/hda1/ext2 defaults 1 1
/Dev/hda2/home ext2 defaults, usrquota 1 2
　　
3. log on as root and create the empty file quota. user # touch/home/quota. user # chmod 600/home/quota. user in the partition directory where quota needs to be set.
　　
4. restart the server
　　
5. allocate the disk quota and the maximum number of files to the specified user.
# Edquota-u jephe
Quota for user jephe
/Dev/hda2: blocks in use: 0, limits (soft = 5000, hard = 6500)
Inodes in use: 356, limits (soft = 1000, hard = 1500)
You only need to change the limits.
　　
Note:
1. when editing/etc/fstab, note that it is usrquota, not userquota.
2. you can view a user's disk quota, such as # quota jephe
