[BlueOnyx:19863] Re: How to change hostname on a BO VM, 5209R

It is kept in /etc/host and in sendmail, apache and admserv config (/etc/admserv/conf/httpd.conf /etc/hostname /etc/mail/sendmail.cf /etc/mail/local-host-names /etc/hosts /etc/HOSTNAME /etc/httpd/conf/vhosts/preview /etc/httpd/conf/httpd.conf)

The best way to do it is to use the GUI: "Server Management" / "Network
Services" / "TCP/IP".

That will then update the hostname in all the relevant places. If your
5209R is fully YUM updated, then it will also use "hostnamectl" to set
the hostname on the OS correctly.

And yes: It's stored all over the place:

It's in CODB in the "System" object.and a whole bunch of config files:

/etc/hostname
/etc/hosts
/etc/mail/local-host-names
/etc/mail/*
/etc/httpd/conf/httpd.conf
/etc/admserv/conf/httpd.conf
/etc/httpd/conf/vhosts/preview

Additionally the AdmServ SSL certificate is also re-generated whenever
the hostname is changed, because the cert needs to match the hostname.

Hence the best way to change it is the GUI, as it ought to do it in all
the relevant places.
