This article shows you how to modify the default startup level of the system in Linux, which is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Modify the system startup level: modify the system to start to 3 multi-user state by default, there are 7 startup levels in Linux, the default is X-Window, like the window mode of Windows, and the operation and configuration of Linux are generally completed by entering commands, like the DOS operating system, how to make Linux enter this mode as soon as it starts?

Step 1: enter Linux as an administrator and modify the file: / etc/inittab file.

Step 2: find "id:5:initdefault:", where 5 is X-Window. For the default run level, we can change 5 to 3.

# 0-halt (Do NOT set initdefault to this)

# 1-Single user mode

# 2-Multiuser, without NFS (The same as 3, if you do not have networking)

# 3-Full multiuser mode

# 4-unused

# 5-X11

# 6-reboot (Do NOT set initdefault to this)

Detailed explanation of each operator level:

0 means shutdown and the machine shuts down.

1 is a single-user mode, similar to the security mode under Win9x.

2 is multi-user mode, but there is no NFS support.

3 is a complete multi-user mode, which is the standard running level.

4 generally not, it can be used to do some things in some special cases. For example, when the laptop battery runs out, you can switch to this mode to make some settings.

5 is X11, which is in the X Window system.

6 to restart, the machine running init 6 will restart.

0 and 6 are generally not used.

Run startx to boot to level 5.
