RHEL: Key System Files


HI

Can someone tell me what are key system files in RHEL? Are these normal file systems such as /etc/system etc...

I assume this would be pretty much similar to other OS's systems...

Regards
Gaz

In opposition to OSes like Windows, where you have OS and programs (mostly) in different directories, UNIX like systems group files according to their functionality (settings, binaries, libraries, ...).
You can get an overview how this is managed here: https://wiki.linuxfoundation.org/en/FHS

RHEL: Key System Files

Most rhel specific configuration files are in /etc/sysconfig. Application specific are in /etc.

It depends on what/how you define "key system files".

It could be referring to things like login, sshd, gdm/kdm/xdm, libraries... or window manager files, or even command interpreters, or even configuration files.

They are in various places... /bin, /lib, /etc, /sbin, /usr/bin, /usr/local, /usr/local/etc ...

It all depends on what you are referring to.

From your point, every directory in RHEL, has its own functions etc... I wanted to know the "KEY FILES" for system settings within RHEL? As you have indicated /etc/sysconfig, /etc... and every OS requires system setting files, consisting of binaries,libraries etc...I dont know wheather there is a right or wrong answer to this..."Key FILES" must be the default files which require any os to be up and running in normal state...

The following questions I was asked, did well in others, but found the below two not well...
How would you fail over a bonded interface to the inactive slave in RHEL?

How would you configure a RHEL NAS share to be automatically mounted?
Any Ideas how and where to troubleshoot or investigate these etc...

Most of the basic system configuration files are in /etc and /etc/sysconfig. Most of the RH specific configurations are in /etc/sysconfig directory tree. Especially those for network control.

Note - in the next version all of the configurations change, some a little, others a lot. Things that used to work, won't. Startup and shutdown will get real flaky.

As for a RHEL NAS share to be automatically mounted--- It depends on WHAT is doing the mounting and WHAT the restrictions are for that specific system. If it is a Windows based system, use Samba to export as it provides the most Windows centric view of filesystems. If it is a UNIX/Linux/BSD based system, usually NFS will be the easiest (but not necessarily the fastest); for most Linux systems, glusterfs is much faster.
