设置centOS 不启动图形界面
我们的linux服务器放在机房长时间运行,一般都不需要图形界面,而且图形界面占用内存。
所以,我们可以通过简单的设置,让linux只启动命令界面,这里以cenOS5.5为例。

[iyunv@localhost ~]#vi /etc/inittab
#
# inittab This file describes how the INIT process should set up
# the system in a certain run-level.

# Modified for RHS Linux by Marc Ewing and Donnie Barnes
#
# 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:5:initdefault:
# System initialization.
si::sysinit:/etc/rc.d/rc.sysinit
重点看这一部分
# 0 - halt (Do NOT set initdefault to this) 停止(不设initdefault这个)
# 1 - Single user mode 单用户模式
# 2 - Multiuser, without NFS (The same as 3, if you do not have networking) 多用户,没有NFS(相当于3,如果你没有网络)
# 3 - Full multiuser mode 充分多用户模式
# 4 - unused 空闲
# 5 - X11 图形界面
# 6 - reboot (Do NOT set initdefault to this) 重启(不设initdefault这个)
id:5:initdefault: ----修改这里的参数
现在我们修改: id:3:initdefault 保存退出
[iyunv@localhost ~]# shutdown now 重启系统,现在就会直接进入命令界面
[iyunv@localhost ~]# vi /etc/inittab
