<div class="moz-text-flowed" style="font-family: -moz-fixed;
font-size: 14px;" lang="x-unicode">I would like permission to edit
this page. The changes I have in mind are:
<br>
<br>
1) It is not necessary to burn a CD/DVD to do a "headless" install
in cases where the installed system has a monitor, but for some
reason cannot support a graphical install directly. This can be
caused by: a server that has too little memory to run a graphical
install, or running the install in a virtual machine where the
install does not work properly in the virtual machine console
because the display is too small and controls are not shown.
<br>
<br>
One situation where I ran into this situation was doing an install
of 6.5 on very old server hardware. The text mode install did not
allow me to preserve partitions, and it was critical to preserve
the /home mount to avoid data loss. I had to run the graphical
install, but the only way to do it on this hardware was to do a
headless install. I was thankful for the page because it helped
me figure out how to do the headless install even though I didn't
need to go to the trouble of making bootable media. It seems
potentially beneficial to make notes that help others also learn
how to do it without burning media if this could solve their
issue.
<br>
<br>
Also, just last week I tried to perform a graphical install CentOS
7.1 in a VM under ESXi 6. The install started out okay, but soon
reached a point where installer windows/panels and controls did
not fit in the console display. While one might try to use TAB to
select hidden controls, it was unsafe to do so because one could
not even see the controls that needed to be manipulated. As I
didn't know how to cure the console size issue during install, it
seemed logical to use a "headless" install method to get a higher
resolution install console via a VNC viewer. This might have
worked except that:
<br>
<br>
2) The instructions given do not work for CentOS 7. Something has
changed. At this point I am still trying to figure out if the
problem is simply a matter of changed kernel options, but after
trying many things for a couple of days, it is clear that at least
7.1 does not work. At the very least, the page could be improved
by documenting this difficulty with 7. I did find a lead tonight
that might allow me to proceed with 7, but I haven't tested it
yet. If it works, then the edits would document changes key to
making the process work for 7.
<br>
<br>
The proposed edits would show how to invoke a "headless" install
by editing kernel parameters at the initial install menu on the
console. Obviously this is not a true "headless install", but
since it can be used to advantage, and as it is A LOT simpler than
burning a CD/DVD, I feel the changes would help others that find
themselves in the situation I was in.
<br>
<br>
I am proposing to do the in <a class="moz-txt-link-freetext"
href="http://wiki.centos.org/TipsAndTricks/VncHeadlessInstall">http://wiki.centos.org/TipsAndTricks/VncHeadlessInstall</a>
though if it is felt that it is better to have the content be on a
sub-page (due to the fact my edits involve using the console), I
am amenable to doing that also.

I have not created my user page at this time, but would plan to
follow the editing guidelines and set it up if I am approved to
make these changes.
<br>
<br>
Thanks for your consideration of this matter.
