How to run commands on CentOS reboot

I want to run the following commands one after the other upon reboot of the server after I do shutdown -r now but not sure how to do it:

• getenforce

• setenforce 0

• systemctl start httpd.service

I’m running CentOS 7.x

Answer

Technically you can crontab it

sudo crontab -e

and add the line

@reboot /somewhere/myscript.sh

and put the 3 commands in the myscript.sh with the proper rights.

But it is a bad idea since you can you just make these changes permanent:

systemctl enable httpd

and

vim /etc/selinux/config 

to set the SELINUX variable to permissive

This will make the configuration permanent across reboot.
