Question

Security in file /etc/rc.d/rc.local

Hi,

I have server with RAID 1. I want to monitoring and receive email alert if have any problem in hard disks.

I readed some guides in internet and they says this:

1- Send alert to email if some disk have problems: nano /etc/mdadm.conf -> add to bottom “MAILADDR root” 2- Enable the scan and monitoring: mdadm --monitor --scan --daemonize 3- Enable the scan and monitoring when restart the server: nano /etc/rc.d/rc.local -> add to bottom “mdadm --monitor --scan --daemonize” 4- Change rc.local permits: chmod +x /etc/rc.d/rc.local

1- This is correct steps or you recommend me other configuration?. 2- Is safe change permits in file “/etc/rc.d/rc.local”?.

Thank you very much. Have a nice day!

Hi,

If I use “systemctl start mdmonitor” and “systemctl enable mdmonitor” I will get the same result that the command “mdadm --monitor --scan --daemonize” ?.

If is same result I not need add command “mdadm --monitor --scan --daemonize” to file “/etc/rc.d/rc.local” and not need change her permits.

Thank you very much.
