Linux basic concepts and Personal notes summary (2)--experiment verification of account and authority management

Thank you!

Instructor: Zhang Ren

Class Teacher: Fu Chunhua I want to give them the highest respect.

Anti-counterfeiting code: Dripping of Grace, the Spring phase report

Impression: When I saw the article on the homepage today, this is my nineth document, I feel very happy in my heart, also really understand

"Effort and harvest are proportional." "That sentence. Just also ready to organize Linux related notes, Heart five mixed, as if yesterday, seems to be in front of.

In a word, without them there is no me today!

Fourth chapter: Account and Authority management

Experimental requirements:

1, set up the user directory/benet/teachers and/benet/students, respectively for the host directory of different identity users, such as Terry User's host directory should be located in/benet/teachers/terry

Note: Sorry, friends! the Black label is my thinking process and verification, mainly to see the correct command and experimental results

Establish a common data store directory to create a/public/directory that allows users in all Benet groups to read, write, execute files, and users of non-technical groups cannot access this directory.

2. Add one: There is a directory Caiwubu in/home, requiring the Finance Manager (Cwjingli) to have full control over the permissions of the directory, the Finance group (CWB, where CW1,CW2 belongs to the members of the Finance group) has permission to read and switch directories, others do not have permissions.

Experimental results: Verify all operating effects as described in the above requirements.

To create a directory:

Create User: Cwjl,cw1,cw2 (example: Groupadd cwjl) Create Group: CWB (Groupadd) (example: Groupadd cwjl),

This is not an example, and then join the group CWB.

also need to modify the initial password: Here the default CWJL,CW1,CW2 is 1, encryption password,:

The final step: start verifying the effect and take care to look at the permissions carefully
