测试CentOS-7-x86_64-Minimal-1708.iso这种光盘安装效果

在dvd1光盘安装选择mininal时有292个包

[root@localhost ~]# rpm -qa|wc -l
292
[root@localhost ~]#

　　

测试下使用mininal的iso文件安装时有什么区别

创建磁盘安装kvm时选择此iso文件

qemu-img create -f qcow2 /data/app/kvm/CentOS-7.4-mininal-x86_64.qcow2 10G
 
virt-install --name CentOS-7.4-mininal-x86_64 \
--virt-type kvm \
--vcpus 4 \
--ram 2048 \
--cdrom=/data/tools/CentOS-7-x86_64-Minimal-1708.iso \
--disk path=/data/app/kvm/CentOS-7.4-mininal-x86_64.qcow2 \
--network bridge=br0 \
--graphics vnc,listen=0.0.0.0 \
--noautoconsole

　　

选择安装包的界面如下

不设置kdump，因为它占内存

291个包

等安装完毕看下哪个包没有

统计比较

[root@openstack-controller-1 /]# vimdiff mininal.txt mininal-iso.txt

　　

选择dvd1光盘安装的多了个qemu-guest-agent的rpm包

选择mininal的iso安装没qemu-guest-agent的rpm包
其余的包一模一样

[root@openstack-controller-1 /]# wc -l mininal.txt
292 mininal.txt
[root@openstack-controller-1 /]# wc -l mininal-iso.txt
291 mininal-iso.txt
[root@openstack-controller-1 /]#
