#/!bin/bash systemctl stop firewalld.service  sleep 3 systemctl disable firewalld.service  sed -n 's/=enforcing/=permissive/' /etc/selinux/config setenforce 0 rm -rf /etc/ssh/ssh_host* rm -rf /etc/udev/rules.d/70* sed '/^MAC/d' "$(find /etc/ -name 'ifcfg\-eno*' -o -name 'ifcfg\-eth*')" sed '/^UUID/d' "$(find /etc/ -name 'ifcfg\-eno*' -o -name 'ifcfg\-eth*')" cat /dev/null > /etc/machine-id rm -rf /etc/hostname systemctl enable initial-setup-graphical.service systemctl enable firstboot-graphical.service cat /dev/null > /etc/sysconfig/firstboot init 0

封装完后启动如下：
