Installation tutorial: Red Hat Enterprise Linux 4, introduction - part 3 (final)



This is the third (and final) part of the RHEL 4 installation tutorial, You can find the first part here and the second part here.

4.1 First boot (setup agent)
When the system comes back up after you have asked it to reboot, login using the root account (remember the root password) and the system will present you with the "first boot" welcome menu:



Click "Next" to move on to the next menu where you will be asked to agree with Red Hat's licensing scheme:



It is important to notice here that this license in many cases refers to licenses included with the source code of each software component that has been shipped with the Red Hat media. Most of the components adhere to the GNU Public License version 2, click here to learn more about what that means.

If you agree tick the "Yes, I agree to the License Agreement" and click "Next".



Here you can set the date and time at your location or alternatively allow the system clock to be set using the Network Time Protocol (NTP) by referring to time servers scattered around the Internet (we won't cover this, if you want to know more about NTP click here).

Set the correct date and time for your system and click "Next". This will bring you to the graphics display configuration menu:



The system assumes a "safe" resolution setting (800x600) and will have attempted to detect the monitor you are using. We will configure the resolution to a more sensible setting, but before we can do that the system need to be made aware of the capabilities of your monitor. To set the monitor type click "Configure":



Depending on what you are using choose the monitor model closest matching your monitor type (if the monitor is not a latest model there is a chance the settings are correct and there won't be a need to change them).

Click "OK" and you will see a menu similar to (if you have chosen a different monitor model the values might differ):





The next menu will give you an opportunity to enable the additional Red Hat subscription service:





You can choose and existing subscription (you must provide a login and password), or at this point you can create a new Red Hat login id and you can skip the dialogue (but you willhave to go past a "why is this important" screen". In this tutorial we will choose the "Tell me why I need to register ....." option so if you have made another choice the next menu will be different:



As we won't be making a registration here make sure to tick the "I can not complete ...." option and click "Next" to continue to the next step:



Here you have an option to create an additional (system) user. It is strongly recommended not to use the system administrator user (root) for day to day tasks (such as surfing the Net, writing reports and so on). The sudo or su commands provide the possibility to run a command as root (once in the case of sudo) or from within a new root shell (with su). Many of the GUI administrative tools provided with RHEL will ask for the root password when invoked by a non-priviliged user.

Create a new user here by specifying a login name (the username field), an optional full name and a (secure) password (you need to confirm this in case of typos). When you're done click "Next" to continue:







If you have any additional software you desire to install here you can insert the extra CDs and install additional documentation, software and plugins. We will skip this step, click "Next":



You have reached the final menu after which you can use the system!

From here you can start exploring the system menus, administration tools, the shell and many other aspects of the installed system.

If you want to review the previous sections, click here for the first part and here for the second part of this tutorial.

Congratulations you have installed Red Hat Enterprise Linux version 4.
