IPADDR=192.168.200.10


PREFIX=24


配置主机名:

hostnamectl set-hostname controller

按 ctrl+d 退出 重新登陆


(2)compute 节点


配置网络:


enp8s0: 192.168.100.20


DEVICE=enp8s0


TYPE=Ethernet


ONBOOT=yes


NM_CONTROLLED=no


BOOTPROTO=static


IPADDR=192.168.100.20


PREFIX=24

DEVICE=enp9s0


TYPE=Ethernet


ONBOOT=yes


NM_CONTROLLED=no


BOOTPROTO=static


IPADDR=192.168.200.20


PREFIX=24


配置主机名:

hostnamectl set-hostname compute

按 ctrl+d 退出 重新登陆


3 配置 yum 源




#Controller 和 compute 节点


(1)yum 源备份


#rm -rf /etc/yum.repos.d/*


(2)创建 repo 文件


【controller】


在/etc/yum.repos.d 创建 centos.repo 源文件

vi /etc/yum.repos.d/local.repo

[centos]


name=centos


baseurl=file:///opt/centos


gpgcheck=0


enabled=1


[iaas]


name=iaas


baseurl=file:///opt/iaas/iaas-repo


gpgcheck=0


enabled=1


【compute】


在/etc/yum.repos.d 创建 centos.repo 源文件

vi /etc/yum.repos.d/local.repo

[root@compute ~]# vi /etc/yum.repos.d/local.repo


[centos]


name=centos


baseurl=ftp://controller/centos


gpgcheck=0


enabled=1


[iaas]


name=iaas


baseurl=ftp://controller/iaas/iaas-repo


gpgcheck=0


enabled=1


主机名映射


[root@controller ~]# vi /etc/hosts


127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4


::1 localhost localhost.localdomain localhost6 localhost6.localdomain6


192.168.100.10 controller


192.168.100.20 compute


[root@compute ~]# vi /etc/hosts


127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4


::1 localhost localhost.localdomain localhost6 localhost6.localdomain6


192.168.100.10 controller


192.168.100.20 compute


(3)挂载 iso 文件


【挂载 CentOS-7-x86_64-DVD-1804.iso】


[root@controller ~]# mount -o loop CentOS-7-x86_64-DVD-1804.iso /mnt/


[root@controller ~]# mkdir /opt/centos


[root@controller ~]# mkdir /opt/iaas


[root@controller ~]# cp -rvf /mnt/* /opt/centos/


[root@controller ~]# umount /mnt/


【挂载 XianDian-IaaS-v2.4.iso】


[root@controller ~]# mount -o loop chinaskills_cloud_iaas.iso /mnt/


mount: /dev/loop0 is write-protected, mounting read-only


[root@controller ~]# cp -rvf /mnt/* /opt/iaas


(4)搭建 ftp 服务器,开启并设置自启


[root@controller ~]# yum install vsftpd -y


[root@controller ~]# vi /etc/vsftpd/vsftpd.conf


添加 anon_root=/opt/


保存退出


[root@controller ~]# systemctl start vsftpd


[root@controller ~]# systemctl enable vsftpd


(5)配置防火墙和 Selinux


【controller/compute】


编辑 selinux 文件

vi /etc/selinux/config

SELINUX=permissive


[root@controller ~]# setenforce 0


关闭防火墙并设置开机不自启

systemctl stop firewalld.service

systemctl disable firewalld.service

(6)清除缓存,验证 yum 源


【controller/compute】

yum clean all

yum list

4 编辑环境变量



controller 和 compute 节点

yum install iaas-xiandian -y

编辑文件/etc/xiandian/openrc.sh,此文件是安装过程中的各项参数,根据每项参数上一行的说明及服务器实际情况进行配置。

Compute 节点修改 tunnel IP


5 通过脚本安装私有云平台




以下脚本按顺序执行!


Controller:


iaas-pre-host.sh


reboot


iaas-install-mysql.sh


iaas-install-keystone.sh


iaas-install-glance.sh


iaas-install-nova-controller.sh


iaas-install-neutron-controller.sh


iaas-install-dashboard.sh


iaas-install-cinder-controller.sh


iaas-install-swift-controller.sh


iaas-install-nova-compute.sh(修改配置之后运行)


Compute:


iaas-pre-host.sh


reboot


iaas-install-nova-compute.sh


iaas-install-neutron-compute.sh


iaas-install-cinder-compute.sh


iaas-install-swift-compute.sh


6 创建云主机




流程:


(1)管理员->资源管理->云主机类型->创建云主机类型


(2)管理员->网络->网络->创建网络


(2)项目->网络->安全组->管理规则->添加规则(ICMP、TCP、UDP)


(3)项目->资源管理->云主机->创建云主机


7 云平台创建云主机



1 创建云主机类型

2 创建云主机网络

选择 vlan 模式,网络要和外网网卡一个网段,段 ID 要选择外网网卡所在网段




2.1 绑定固定网络


3 修改安全组



4 上传镜像


[root@controller ~]# source /etc/keystone/admin-openrc.sh


[root@controller ~]# glance image-create --name "CentOS7.5" --disk-format qcow2 --container-format bare --progress < /opt/iaas/images/CentOS_7.5_x86_64_XD.qcow2


[=============================>] 100%


+------------------+--------------------------------------+



5 创建云主机



6 测试连接




8 Openstack 命令创建云主机



1 创建云主机类型

使用命令创建一个名为 test ,ID 为 6 ,内存为 2048MB ,磁盘为 10GB ,vcpu 数量为 2 的云主机类型。


nova flavor-create test 6 2048 10 2


+----+------+-----------+------+-----------+------+-------+-------------+-----------+-------------+


| ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public | Description |


+----+------+-----------+------+-----------+------+-------+-------------+-----------+-------------+


| 6 | test | 2048 | 10 | 0 | | 2 | 1.0 | True | - |


+----+------+-----------+------+-----------+------+-------+-------------+-----------+-------------

2 创建云主机网络

思路:查看云平台创建好的网络,查看它的详细信息,用命令创建的时候,指定参数即可!


[root@controller ~]# neutron net-create --router:external --provider:network_type vlan --provider:physical_network provider --provider:segmentation_id 200 ext


neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
