相信很多在做web开发、后台服务、api开发等IT朋友,都会接触到Linux、Ubuntu、Unix等系统的开发,如何在不卸载桌面的前提下开机能直接进入命令界面。
以Ubuntu16.04 为例(VM Ware 14版安装界面版):
使用centos的朋友可以去官网进行下载资源。
下载地址:https://www.centos.org/download/
输入:
$> vim /etc/inittab
在默认的 run level 设置中,按照如下设置。id:5:initdefault:(默认的 run level 等级为 5,即图形界面)
将第一行的 5 修改为 3 即可。
- # inittab is only used by upstart for the default runlevel.
- #
- # ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.
- #
- # System initialization is started by /etc/init/rcS.conf
- #
- # Individual runlevels are started by /etc/init/rc.conf
- #
- # Ctrl-Alt-Delete is handled by /etc/init/control-alt-delete.conf
- #
- # Terminal gettys are handled by /etc/init/tty.conf and /etc/init/serial.conf,
- # with configuration in /etc/sysconfig/init.
- #
- # For information on how to write upstart event handlers, or how
- # upstart works, see init(5), init(8), and initctl(8).
- #
- # Default runlevel. The runlevels used 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:
使用命令:
$> reboot
