主要介绍下面几个内容
通过koan自动重装系统；
自定义系统的安装；
示例自定义系统如何bonding及bridge；
接上一篇
#挂载centos7.1 的iso
mkdir -p /var/iso/Linux/Centos/x86_64/7.1
mount -o loop /home/CentOS-7-x86_64-DVD-1503.iso /var/iso/Linux/Centos/x86_64/7.1
cobbler import --path=/var/iso/Linux/Centos/x86_64/7.1 --name CentOS-7.1-1503-x86_64
#增加7.1的profile
cobbler profile add --name=CentOS_7.1-x86_64_server --distro=CentOS-7.1-1503-x86_64 --kickstart=/var/lib/cobbler/kickstarts/server.ks
# centos7 ks 文件配置
19、确保tftp服务已启动
lsof -i udp:69
20、利用koan自动安装系统
#koan
主机第一次安装完成后
yum install epel-release
yum install -y koan
# --display
koan --display --server=192.168.1.164 --profile=CentOS_7-x86_64_server
# --replace-self
koan --replace-self --server=192.168.1.164 --profile=CentOS_7-x86_64_server
修正不能识别centos7的故障
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.0.1406 (Core)
koan里面的python代码不能判断 7.0.1406的版本号，因为它太长了：（ ，手动删除1406，即可顺利通过kocan重装.
centos7.1503 无上述问题
21、自定义安装，根据mac地址不同
# docker1
