We can create groups of users according to their needs: Groupadd Group Name 5. Delete a group Similarly, we sometimes need to delete a

Failure Phenomenon: How should the actual capacity of the various RAID groups be calculated? 　Solution: 1, RAID 0 (striped disk Array without Fault tolerance): RAID0 all hard drives in parallel, capacity is the sum of all hard disk capacity, and hard disk access speed depends on how many hard drives, when the number of hard drives RAID The faster the 0 array access rate is, the greater capacity efficiency is the highest in all raid

From the security point of view, multi-user management of the system more secure, such as Beinan users under a file do not want to let other users see, just set up the file permissions, only Beinan a user readable writable editable on the line, so that only Beinan a user can operate their private files , Linux in multi-user performance is the best, Linux can well protect the security of each user, but we also have to learn that Linux is a safe system, if there i

Linux users, groups to explain and add In Linux systems, user and group related permissions are the basic content of Linux system management. Linux systems can run better and more securely with specific users, groups, and corresponding permissions. For this part, I summarized the following notes in my training and study as follows: Create groups and Users: 1. Cr
