如何修改登录画面

先修改文件 /etc/issue 改为相要显示的内容， 再修改文件 /etc/rc.d/rc.local(RedHat) 或 /etc/rc.d/rc.S(Slackware) 把下面几句注释掉：

# This will overwrite /etc/issue at every boot. So, make any changes you

# want to make to /etc/issue here or you will lose them when you reboot.

echo "" > /etc/issue

echo "Red Hat Linux $R" >> /etc/issue

echo "Kernel $(uname -r) on $a $(uname -m)" >> /etc/issue

cp -f /etc/issue /etc/issue.net

echo >> /etc/issue

不然的话每次重新启动 /etc/issue 都会被更改。
