就是找不到inittab

解决办法1

因为版本更新现在已经不用inittab文件了

而是再这里找

代码

sudo raspi-config

我要找的是关闭串口登录的文件

#T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

需要用#注释掉行

sudo raspi-config

这个代码直接图形化了

先选interfacing options (各种接口的选项)

回车进入后选serial(串口)再点击回车

这时会问你YES 还是 NO,要关闭串口登录所以选择NO.

再点击回车

又问你保存不保存选“是”。再出来的界面选确定

然后选Finsh(敲击键盘“→”)

完成

借鉴参考大神{感谢大神分享}

第二种办法我没有试过

inittab配置文件

如下

### Beginning of inittab ###

# inittab       This file describes how the INIT process should set up
#               the system in a certain run-level.
#
# Author:       Miquel van Smoorenburg, <miquels@drinkel.nl.mugnet.org>
#               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)
