Why CentOS can't log in to root and how to solve it? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Situation 1:

If the ssh terminal that is still connected is not disconnected, you can resume it by executing the following command:

# LD_PRELOAD=/lib64/libc-2.12.so ln-s / lib64/libc-2.12.so / lib64/libc.so.6

Case 2:

Ssh has been disconnected, unable to create a new ssh connection, restart the system, reported an error and could not enter the system.

An error occurred: Kernel panic-not syncing: Attempted to kill init!

Treatment method

Enter rescue rescue mode and copy the linked file to the deleted file system.

The steps are as follows:

1. Enter the BIOS settings when booting, and modify the BOOT boot sequence to start CD-ROM Drive on CD first.

2. Boot the CD after rebooting the system, enter the installation startup menu, and select "Rescue install system" rescue mode.

3. Go to the Rescue interface and select Continue

4. Mount the system under / mnt/sysimage, and select OK (if you want to go to the root environment, run the chroot / mnt/sysimage command, which is not required here)

5. Select the entry mode: shell enters the command line mode, fakd is the diagnostic mode, reboot restarts the computer, select shell here

6. Enter the shell command line, and the prompt is bash-4.1#

7. Do not execute chroot / mnt/sysimage, because the hard disk file system is in this directory. Just copy the soft connection from / lib64, as follows:

Bash-4.1# cd / lib64

Bash-4.1# cp-d libc.so.6 / mnt/sysimage/lib64/libc.so.6

Bash-4.1# reboot

And then it can return to normal.
