在/etc/inittab里面设置autologin失败! 为什么?

ejeker

我用RHEL6.3，
[root@dhcp-10-35-12-184 ~]# cat /etc/inittab
# inittab is only used by upstart for the default runlevel.
#.....
#
id:3:initdefault:

1:2345:respawn:/sbin/mingetty --noclear --autologin root tty1

然后重启，用root登陆，并没有跳过控制台输用户名/密码的步骤。
但是同样我在Suse11下，找到/etc/inittab中tty1这一行，如上设置，重启以后tty1就能自动登陆。奇怪了。

要如何设置呢?

RHEL6的要在/etc/init里面的tty.conf里修改，inittab只是对default runlevel的设置而已。楼主可以在 /etc/init/tty.conf修改exec /sbin/mingetty --noclear --autologin=root $TTY ，就可以了。

more /etc/inittab看下。

1#已经用cat给出来了，试了下，一样的效果。

就这两行，为什么autologin不行呢?

我是在VMware里面运行的。dmesg的内容如下。还有什么系统日志需要查看的?

是否跟pam有关呢？会不会禁止了tty1登陆呢？看看/etc/securetty

果然,RH5可以改/etc/inittab而RH6要改/etc/init/tty.conf文件
RH5和6果然不一样。

问题解决了，谢谢高手!

学习了~这应该是和Suse不一样的~
