Editor to share with you how to solve the problem of Linux mistakenly deleting users' home directories, I believe most people do not know much about it, so share this article for your reference. I hope you will gain a lot after reading this article. Let's learn about it together.

In production, a user's home directory may be deleted due to misoperation, so you need to install the template file of the user's home directory to create a new user, and then restore it and have the same permissions as before.

1. Create a new user for testing

[root@centos6 aubin] # useradd wangcai

two。 A folder with the same name is automatically created under / home when the new user is created.

[root@centos6 home] # lsaubin gentoo li wangcai

3. First of all, check the files and permissions in the user's home directory to verify that there is no deviation in the permissions after recovery.

[root@centos6 aubin] # ls / home/wangcai/-altotal 28drwxMurray. 4 wangcai wangcai 4096 Jul 24 19:11. Drwxr-xr-x. 6 root root 4096 Jul 24 19:11.-rw-r--r--. 1 wangcai wangcai 18 Mar 23 08:15 .bash _ logout-rw-r--r--. 1 wangcai wangcai 176 Mar 23 08:15 .bash _ profile-rw-r--r--. 1 wangcai wangcai 124 Mar 23 08:15. Bashrcdrwxr-xr-x. 2 wangcai wangcai 4096 Nov 12 2010. Gnome2drwxr-xr-x. 4 wangcai wangcai 4096 Jul 14 10:38 .mozilla

3. Here, the home directory is deleted by simulating misoperation in production.

[root@centos6 home] # rm-rf wangcai/ [root@centos6 home] # ls aubin gentoo li # Delete the wangcai directory

4. Copy all the files in skel to Wangcai under home. The files in the skel directory are files in the home directory when you create a new user. In other words, the files in skel are templates for creating a user's home directory.

[root@centos6 home] # cp / etc/skel/ / home/wangcai-a

5. Check the copied wangcai folder and notice that both the owner and the group are root, so you need to change it to wangcai

[root@centos6 home] # ls-aldrwxr-xr-x. 4 root root 4096 Jul 14 10:49 wangcai

6. First, change the permissions of the wnagcai directory to 700

[root@centos6 home] # chmod 700 wangcai/

7. Finally, the group and owner of all the files in the wangcai directory are changed to users themselves.

The-R option is recursive and changes the settings for all files in the directory.

[root@centos6 home] # chown wangcai:wangcai wangcai/-R [root@centos6 home] # ls-al wangcai/total 28drwxr-xr-x. 4 wangcai wangcai 4096 Jul 14 10:49. Drwxr-xr-x. 6 root root 4096 Jul 24 20:06.-rw-r--r--. 1 wangcai wangcai 18 Mar 23 08:15 .bash _ logout-rw-r--r--. 1 wangcai wangcai 176 Mar 23 08:15 .bash _ profile-rw-r--r--. 1 wangcai wangcai 124 Mar 23 08:15. Bashrcdrwxr-xr-x. 2 wangcai wangcai 4096 Nov 12 2010. Gnome2drwxr-xr-x. 4 wangcai wangcai 4096 Jul 14 10:38 .mozilla

At this point, the user's home directory is restored, and after comparison with the previous directory permissions are exactly the same.
