Restore deleted files with Extundelete in Linux

In Linux, we will encounter accidentally delete files, then we can use Extundelete to recover these deleted files.
In this experiment, I'll enable rh6-2 and use Xshell to connect remotely.
First step: Add a hard drive
How to add a hard drive I've talked about it before.
Reboot after adding hard drive (init 6)
Next, partition the hard drive:

To format:

Mount:

Step two: Create a yum repository
To mount the optical drive:

Switch to the ETC directory:

Delete and then re-build a directory and edit it with the VI editor:

Enter A to enter:

Note: The path in BASEURL=FILE:///MNT is the path that is mounted, file://is the fixed format,/mnt mount Path, this experiment is mounted to the MNT directory.
Then enter the Yum list to see if the Yum repository can be used:

Step three: Mount the shared folder
I put the package in the Lamp folder under the C drive.

Then click "Add" and the following screen will appear:

Right is the permission setting, select Read, and then select Share:

Unblock guest and set local policy permissions (user rights Assignment and security options) I've written about it in previous experiments, and it's not clear that I can look through my previous blogs.
Next scan the shared file:

Create an empty folder and mount it:

Fourth Step: Install
Extract:
First switch to the/lamp directory and see if there are any compressed packages to unzip:

Unzip (unzip to/OPT):

To switch to/OPT, the installation package is already available:

Install the Environment pack:

Once you have installed the dependent packages, reinstall the E2fsprogs-devel package once again:

Installing GCC gcc-c++:

Switch to the installation package and configure the configuration file:

The configuration file is converted to binary:

Installation:

Fifth step: Recover deleted files
To add a folder under the/ABC directory:

Simulated accidental deletion of files:

To unpack a device:

Note: The unpacking device is not in the current directory
Recover files:

Switch to the following directory and find the file that was accidentally deleted:

To recover, you can copy directly:
