In this video, you will be familiar with RHEL 7 Desktop GUI. I have explained. In other words, I will introduce you with the Red Hat Enterprise Linux 7 (RHEL 7) GNOME desktop. You can also call it as Red Hat GUI or Graphical User Interface. You don’t get this Graphical Mode unless you install it. To know how to install GNOME desktop in redhat 7, please refer my previous video. You can see the Full name of currently logged on User, current day and time, the network icon, volume icon or the volume manager. In the Application and in the Favorites, the most used applications or default applications that are likely to be used most are listed. The firefox is the default browser of the Red Hat. We can also see the file manager named Files, there we can see the user default and later created files and folders. You can create, edit or delete file and folder there. Also, we can see some files and folders locked. That means they are locked for this user and to open them, administrator privilege is required. Inside the folder, if you try to view the contents of the ‘web’ directory, you are prompted with a message “This location could not be displayed, You do not have the permission necessary to view the contentes of ‘Web’. Just click on OK, go back steps and then close the windows. To open the terminal, go to Applications and then click on Terminal. The terminal is opened. We have nothing to do now, so let’s close it. Now, let’s go to the Applications, go to System tools and then Settings. This is quite equivalent with the control panel in Windows Operating systems. You can see there the Personal, hardware and system tools. Down, below in the system, we can see users, if you double click on it, you can see the user information. Currently regmisan user is logged in. There are other accounts as well, if you click on them, you can read their properties and their status. You can also easily lock or unlock an user. Let’s close and get out of this window. In the Applications, then go to System tools then Disks, we can see the available device blocks—hard drives, CD /DVD drives or any disk or drive attached to the system. Currently there are 3 drives, we can see their size, name, partitioning type, file system, their mount point directory and whole bunch of things. Likewise, in the system tools, we can see another very important section, that is ‘System Monitor’ liket that of ‘Task Manager’ in Windows System. Let’s double click on system monitor to monitor our system. We can see the processes that are currently running. We can see so many services are running with their process id, and appropriate priority. Click on Refresh to get fresh processes. If you click on the ‘view’ drop-down menu, you can see the four items, the ‘all processes’ lists the processes used by all the users in the system. You can see the first process is of the user ‘regmisan’ and the second and some other are of root user. The ‘My Processes’ is for the currently logged on user’s process. And the ‘active processes’ list the processes that are currently active in the system. If you want to kill a process, just select the process and click on ‘End Process’ at the end of the interface. You get a prompt to verify. Just click on ‘End process’. The system monitor interface is closes because, we just ended the process. Finally, Once again go the ‘System Monitor’ GUI then Go to the Resources tab, here we can see the current CPU utilization, Memory or Ram and Swap memory usage and Network utilization or history. In the File System tab, we can see the devices, their name, their mount point directory, total capacity, available and used. From these three tabs, we can monitor our Red Hat system easily. Like wise, from the System Tools, we can see the system logs, which is another most important monitoring tools. If you are not a root user, you will have to enter the password to see the logs. All the history and errors can be seen here. Last but not least, we can also customize startup applications from the system tools. We can add in the list if we want a program to run at boot time or we can remove from this list to stop running the program at boot time. Okay friends, this is the end of this session, I hope you became quiet familiar with the Red hat Graphical User Interface. We will however, administer the system, almost everything from the bash terminal. We will be familiar with that too, in the coming sessions. Thank you for watching the video.
