I need to change the host name on a test server, and in the past when I used hostname to change the hostname, it did not seem to change it everywhere.
I really don't want to do a rebuild just yet, but I have to feel confident that hostname is really changed (reboot is not too much of an issue).
What is the recommened practice? Other than get it right the first time.
To make the change permanent, edit /etc/ssyconfig/network and set the desired hostname after HOSTNAME=.
I did this and rebooted, but /etc/sysconfig/network-scripts/ifcfg-eth0 was not changed. NetworkManager does not seem to have a dialog for changing it there. I manually edited the file. When I saved the file, NM seems to have noticed the change and auto-restarted the interface.
If you aren't moving this box around onto different networks all the time just get rid of NetworkManager so it will stop screwing up your settings.
That will take me back a few years in what I am doing! What do I gain with this?
Do I just erase NetworkManager for this?
In kickstart do I specify to exclude it (-NetworkManager)
I go back to 'service network restart'?
NetworkManager is handy for a laptop where you want to deal with different wifi settings and moving around among dhcp networks, but for servers you probably don't want it to overwrite your static configs and /etc/resolv.conf, etc. I've usually let it install but then service NetworkManger stop chkconfig NetworkManager off
And when you edit ifcfg-eth0 what command restarts the interface?
to keep it from running when I set static configs. I'm not sure what happens if you don't install it at all - that would probably be even better.
