SELinux (Security-Enhanced Linux) is a special mechanism that is responsible for kernel security. This guide will be useful for users with a CentOS 6, 7, and 8 virtual machine.
Disable and uninstall SELinux
# setenforce 0
# yum remove selinux-policy\*
# rm -rf /etc/selinux/targeted /etc/selinux/configInstall SELinux
# yum install selinux-policy-targeted
# yum install selinux-policy-devel policycoreutils
# touch /.autorelabel; rebootSELinux will detect the /.autorelabel file upon reboot, and then reconfigure all the files in the correct SELinux contexts. If you have many files in your virtual machine, then VPS may be unavailable for a long time.
Note!
If SELinux is not already installed, then you need to go to step 2 – installing SELinux. If SELinux is installed on your virtual server, then you need to remove it (to reset the policy to the default settings)
