Linux 启动时执行交互式脚本并显示为默认tty连接的监视器屏幕

我已将Centos 6配置为在每次启动时自动登录

我已经修改了/etc/init/tty.conf来实现这一点，效果很好

/etc/init/tty.conf的内容

stop on runlevel [S016]

respawn
instance $TTY
#exec /sbin/mingetty $TTY
exec /sbin/mingetty --autologin root $TTY
usage 'tty TTY=/dev/ttyX  - where X is console id'

然后，我将~/.bash_配置文件配置为运行脚本。请参阅下面的内容

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH


echo "This is one time" >/tmp/one.txt

正如您在上面看到的，我将echo'd文本添加到文件/tmp/one.txt中， 文件中的预期文本应仅显示一次。但由于某些原因，此脚本执行了3次

如果I tail-f/tmp/one.txt，则在/tmp/one.txt中会出现以下内容。它显示脚本执行了3次

tail -f /netboot/tmp/one.txt
This is one time
tail: /netboot/tmp/one.txt: file truncated
This is one time
tail: /netboot/tmp/one.txt: file truncated
This is one time
tail: /netboot/tmp/one.txt: file truncated
This is one time

我能做些什么来防止它执行多次，我只想让它运行一次，就这样

我不得不从/etc/init/TTY.conf文件中删除respawn instance$TTY

在修复之前，/etc/init/tty.conf如下所示

stop on runlevel [S016]

respawn
instance $TTY
#exec /sbin/mingetty $TTY
exec /sbin/mingetty --autologin root $TTY
usage 'tty TTY=/dev/ttyX  - where X is console id'

stop on runlevel [S016]


exec /sbin/mingetty --autologin root $TTY
usage 'tty TTY=/dev/ttyX  - where X is console id'

解决问题后/etc/init/tty.conf如下所示

stop on runlevel [S016]

respawn
instance $TTY
#exec /sbin/mingetty $TTY
exec /sbin/mingetty --autologin root $TTY
usage 'tty TTY=/dev/ttyX  - where X is console id'

stop on runlevel [S016]


exec /sbin/mingetty --autologin root $TTY
usage 'tty TTY=/dev/ttyX  - where X is console id'

这解决了我上面解释的问题
