[Solved] Linux No access to the system error: Failed to load SELinux policy. Freezing

Cause of error

SELinux is shut down by configuration, resulting in misoperation

The value of the "SELINUX" parameter in the configuration file /etc/selinux/config should be changed to
# SELINUX=enforcing Original configuration
SELINUX=disabled Correct

However, "SELINUXTYPE" is mistaken for "SELINUX" and the SELINUXTYPE parameter is set as follows
#SELINUXTYPE=targeted Original configuration This does not need to be changed.
SELINUXTYPE=disabled Error

Wrong result

After restart, the machine will report a failed to load SELinux policy. Freezing error, which causes it to fail to start all the time


1. On the startup page, select the kernel you want to start and press e to enter grub edit page

2. Find the line linux16 in lang = zh_ Cn.utf-8 space plus SELinux = 0 or forcing = 0 (Note: I joined SELinux = 0 to take effect.)

3. Then start with Ctrl + X to see the familiar login interface

4. Modify SELinux configuration file and close SELinux properly

vim /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#    enforcing - SELinux security policy is enforced.
#    permissive - SELinux prints warnings instead of enforcing.
#    disabled - No SELinux policy is loaded.
# SELINUXTYPE= can take one of three two values:
#    targeted - Targeted processes are protected,
#    minimum - Modification of targeted policy. Only selected processes are protected. 
#    mls - Multi Level Security protection.

After modification, restart
