The server administrator has significantly more authority than users. You can log in to the server as an administrator both remotely and locally. In the second case, greater security is provided, since communication channels are not involved.
Instructions
Step 1
If you are near a server running a Linux operating system and the desktop is already displayed on its screen, end the current session first. The way to complete it depends on which GUI is running. For example, if this is KDE, click on the button with the letter K and a cogwheel, then select "End Session" from the menu that appears and click the "End Current Session" button. Then, in the fields that appear, enter the username root and the password for this user. A new desktop will appear and you will be able to run programs and run programs as administrator.
Step 2
On a Windows server, do the same, but after logging out, press Ctrl-Alt-Del. Login and password fields will appear only after that. Also note that the root user on this OS is not called root, but "Administrator".
Step 3
On a server running Linux, if there is no graphics subsystem on it, first log off someone else's current session (if it is open) with the logout command. Then enter the username root followed by the password for the root user. You can do the same in the GUI by running any terminal emulator like rxvt, xterm, or Konsole, but instead of using the logout command, you will have to enter login. Now all commands in this terminal window will be executed as the root user (you can even run programs using graphics on his behalf), while the desktop will remain the same.
Step 4
Never connect to the server remotely via Telnet. If the SSH (text) or VNC (graphical) protocol is used, enter the login and password in the corresponding fields of the client program. After that, the login under the appropriate name will occur automatically. The server settings must have permission to connect using the appropriate protocols.
Step 5
You can also log in as an administrator to the server web interface. In this case, you will not get access to all the functions of the machine, but only to all the functions of the "engine" of the forum, website, etc. To do this, go to the site using a browser, and then click on the "Login" link. Enter your administrator login and password. If we are talking about an online store, the "Login" link for additional security on the home page may not be present. Find out its address from the documentation for the "engine".
Step 6
Regardless of how you logged on to the server as an administrator, be sure to log out after completing the steps you want to take. To do this, enter the logout command in the text interface, logout in the graphical interface, as described above, and in the web interface, click the Logout link.
