安装cloud init

yum install cloud-init  --allowerasing

[root@localhost rules.d]# systemctl enable cloud-init-local.service cloud-init.service cloud-config.service cloud-final.service
[root@localhost rules.d]# cloud-init -v
/usr/bin/cloud-init 17.1

chmod +x  dhcp-all-interfaces.sh

3、添加/etc/udev/rules.d/99-dhcp-all-interfaces.rules

[root@localhost sbin]# cd /etc/udev/rules.d/
[root@localhost rules.d]# ls
[root@localhost rules.d]# touch 99-dhcp-all-interfaces.rules
[root@localhost rules.d]# ls
99-dhcp-all-interfaces.rules

 cat /etc/udev/rules.d/99-dhcp-all-interfaces.rules
SUBSYSTEM=="net", KERNEL!="lo", ACTION=="add", TAG+="systemd", ENV{SYSTEMD_WANTS}+="dhcp-interface@$name.service"

4、添加devuser账号

useradd -m devuser /bin/bash
echo -e 'devuser ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers
echo "devuser:xxxxx" | chpasswd

5、cloud init默认登陆用户

useradd -m euleros -s /bin/bash 
mkdir -p /home/euleros/.ssh
touch /home/euleros/.ssh/authorized_keys
chown euleros:euleros  -R /home/euleros

 查看/home/devuser/下是否存在.bash_profile 、.bashrc

[root@localhost rules.d]# cp /etc/skel/.bashrc /home/devuser/
[root@localhost rules.d]# cp /etc/skel/.bash_profile   /home/devuser/

退出
[root@localhost rules.d]# umount /proc/ /sys/ /dev/
[root@localhost rules.d]# exit
exit
