Set CentOS not to enable graphical interface

Setting centOS does not enable graphical interfaces. our linux server runs in the IDC for a long time. generally, graphical interfaces are not required and the graphic interface occupies memory. Therefore, we can use simple settings to enable linux to only start the command interface. Here we take cenOS5.5 as an example. ---------------------

Set centOS not to enable graphical interface

Our linux server runs in the data center for a long time. Generally, the graphic interface is not required, and the graphic interface occupies the memory.

Therefore, we can use simple settings to enable linux to only start the command interface. Here we take cenOS5.5 as an example.

Focus on this part

#0-halt (Do NOT set initdefault to this) stop (no initdefault)

#1-Single user mode

#2-Multiuser, without NFS (The same as 3, if you do not have networking) multiple users, no NFS (equivalent to 3, if you do not have a network)

#3-Full multiuser mode Full multi-user mode

#4-unused Idle

#5-X11 graphic interface

#6-reboot (Do NOT set initdefault to this) restart (no initdefault)

Id: 5: initdefault: ---- modify the parameters here

 

Now we modify: id: 3: initdefault to save and exit.
