OVH Public Cloud CentOS 7 Change Hostname

If you’ve tried to change the hostname on your OVH public cloud instance running CentOS 7, you may have had issues with it persisting after reboot.

Took me way to long to find this solution, but someone had already spent way too much time figuring it out.

This GitHub Gist explains it all

Basically you need to edit /etc/cloud/cloud.cfg and add “preserve_hostname: true” and then set your hostname using hostnamectl.

hostnamectl –transient set-hostname
hostnamectl –static set-hostname

Hope that helps and thank zmjwong!

Exim4 and PHP and PHP-CGI mail() function using incorrect From: and applying Sender: headers.

If you're using Exim4 and PHP as a module or as a CGI with suexec. You may have noticed some issues with your mail. Specifically you would have noticed that either the "From:" header was using "nobody@machinename" or "user@machine name, its also possibly that you had an additional header called "Sender:". There are two things you need to do to fix this. You first need to make sure that your "php.ini" has the following value "sendmail_path = /usr/sbin/sendmail -t -i". Which is the default, double check this variable as it might be set to something else.
