Single User Mode (sometimes known as Maintenance Mode) is a mode in Unix-like operating systems such as Linux operate, where a handful of services are started at system boot for basic functionality to enable a single superuser perform certain critical tasks.
It is runlevel 1 under system SysV init, and runlevel1.target or rescue.target in systemd. Importantly, the services, if any, started at this runlevel/target varies by distribution. It’s generally useful for maintenance or emergency repairs (since it doesn’t offer any network services at all), when a computer is not capable of normal operations.
Once you have decided to enter single user mode for maintenance or recover from crash you will need to VNC to the server or in other words emulation of physical console. Don’t worry about logging into the server at this point, since this process will need you to reboot the server.
The process is the same for both RedHat/CentOS 7 and 8
Once you issue the hard reboot, you may need to click Refresh in the top right of the VNC screen since the hard reboot will reset that connection. You need to click this refresh very quickly otherwise you will miss the boot screen where you can interrupt the boot process. Continue reading

One of them is by offering add-ons, extra services, and gaining revenue through ads.
Of course ads can be really annoying and that’s how to disable ads in Xiaomi MIUI: Continue reading
