云计算平台的拓扑图如图1所示,IP地址规划如下图所示。
一、私有云部署运维
1 划分compute磁盘
在compute节点上利用空白分区划分2个100G分区。
[root@compute ~]# parted /dev/md126 GNU Parted 3.1 Using /dev/md126 Welcome to GNU Parted! Type 'help' to view a list of commands.

2 配置网络、主机名
修改和添加/etc/sysconfig/network-scripts/ifcfg-enp*(具体的网口)文件。
(1)controller节点 配置网络: enp8s0: 192.168.100.10 DEVICE=enp8s0 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=no BOOTPROTO=static IPADDR=192.168.100.10 PREFIX=24 GATEWAY=192.168.100.1 enp9s0: 192.168.200.10 DEVICE=enp9s0 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=no BOOTPROTO=static 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 GATEWAY=192.168.100.1 enp9s0: 192.168.200.20 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
在controller节点上利用/opt/centos目录中的软件包安装httpd服务,设置开机自启动,并使用http提供yum仓库服务,在http服务默认工作目录下创建openstack和centos目录,将需要用到的源文件分别复制到这两个目录下。分别设置controller节点和compute节点的yum源文件http.repo 在/etc/yum.repos.d
#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controller节点上利用/opt/centos目录中的软件包安装httpd服务,设置开机自启动,并使用http提供yum仓库服务,在http服务默认工作目录下创建openstack和centos目录,将需要用到的源文件分别复制到这两个目录下。分别设置controller节点和compute节点的yum源文件http.repo 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
将提供的CentOS-7-x86_64-DVD-1804.iso和chinaskills_cloud_iaas.iso光盘镜像上传到controller节点/root目录下,然后在/opt目录下分别创建centos目录和openstack目录,并将镜像文件CentOS-7-x86_64-DVD-1804.iso挂载到centos目录下,将镜像文件chinaskills_cloud_iaas.iso挂载到openstack目录下。
【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。

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!
