This article is about how CentOS 6.5 changes the startup interface. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

I. Cancel the startup picture

I have long wanted to say goodbye to the graphical interface completely, and I simply don't even want the boot screen. The black screen shows a large number of boot messages, which gives people a cool feeling, although it is still unclear what those messages mean.^_^

vim /etc/grub.conf。

Delete "rhgb quiet," ZZ. OK, reboot, it's working.

Explanation:

Rhgb: replace text messages during startup with images that can be viewed with the dmesg command after startup. rhgb = redhat graphical boot - This is a GUI mode booting screen with most of the information hidden while the user sees a rotating activity icon spining and brief information as to what the computer is doing.

quite: Only important information is displayed during startup, messages such as hardware self-test are not echoed. quiet = hides the majority of boot messages before rhgb starts. These are supposed to make the common user more comfortable. They get alarmed about seeing the kernel and initializing messages, so they hide them for their comfort.

Second, boot into the text interface

Next, we can enter the GUI by default by editing the/etc/inittab file. Change the 3 in id:3:initdefault to 5, so that the system will enter text mode directly after booting. The following is part of the etc/inittab file that configures booting into graphics mode:

#Default runlevel.The runlevels used by RHS are:

# 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)

id:3:initdefault:

This part of the information indicates that the Linux operating system has six different runlevels, and under different runlevels, the system has different states. These six runlevels are:

#0: Shutdown (remember not to set initdefault to 0 because that will prevent Linux from starting)

#1: Single-user mode, just like Safe Mode under Win9X.

#2: Multiple users, but no NFS.

#3: Full multi-user mode, standard run-level.

#4: Generally not used, in some special cases can be used to do something.

#5: X11, i.e. go to X-Window System.

#6: Restart (remember not to set initdefault to 6, otherwise Linux will restart constantly).

Run level 3 is the standard Console character interface mode we want to enter.
