How to run scripts in CentoS startup?

You have the commands set in the script file

If this is it, try to give the file full permission and make it executable.

  

chmod +777 /etc/init.d/script

     

chmod + x /etc/init.d/script

/etc/rc.local or /etc/rc.d/rc.local are no longer executed due to changes in CentOS.

To continue using them, you need to keep /etc/rc.d/rc.local as executable:

chmod +x /etc/rc.d/rc.local

Debug

To debug the problem, it would be a good idea to redirect the output of the script ( /etc/init.d/script > /var/log/seu_log ) to make sure the script is running or not.

Example:

# touch > /root/meu_script.sh
# touch > /var/log/meu_log && chmod 777 /var/log/meu_log

Save the content:

#!/bin/bash
echo 'Nossa! Estou vivo!'

Give permission:

chmod +x /root/meu_script.sh

And schedule your boot run to:

/etc/init.d/script > /var/log/meu_log

After booting, make sure the /var/log/meu_log file is empty or written. If it is empty, obviously the script did not run at boot.
