Disable SELinux CentOS 7
This blog covers the basic steps to disable SELinux on CentOS 7
first we need to see how SELinux is configured, issue the sestatus command
sestatus
as you can see the current mode is enforcing, issue the following command to disable it
sed -i ‘s/enforcing/disabled/g‘ /etc/selinux/config /etc/selinux/config
now issue the sestatus command again
sestatus
you should see that the config file, is now going to load it as disabled after the next reboot.
shutdown -r now
issue a reboot
