1、前期准备与节点规划
- 使用搭建的操作系统是：
CentOS-7-x86_64-DVD-1804.iso
- 使用搭建的镜像是：
chinaskills_cloud_iaas.iso
- 使用远程连接的工具是：
xshell
- 搭建方式：使用两台先电云计算服务器进行搭建，一个作为控制节点。另一个作为计算节点。
- 节点网络规划
| 节点 | 内网IP地址 | 外网IP地址 |
| controller | 192.168.1.10 | 192.168.101.10 |
| compute | 192.168.1.20 | 192.168.101.20 |
注意：IP地址根据实际组网情况进行填写配置
2、基础环境配置与说明
| 云计算IaaS控制节点 | 云计算IaaS计算节点 |
| Keystone安全认证服务 | |
| Glance镜像服务 | |
| Nova计算控制服务 | Nova Compute计算服务 |
| Dashboard管理界面 | |
| Neutron Server网络服务 | Neutron节点网络服务 |
| Cinder存储控制服务 | Cinder Volume存储服务 |
| Rabbit消息服务 | |
| Mysql数据库 |
| Swift 代理服务 | Swift 存储服务 |
| Heat编配服务 | |
| Ceilometer 监控服务 | Ceilometer监控代理 |
说明：存储节点安装操作系统时需划分两个空白分区，作为cinder和swift存储磁盘搭建 ftp服务器作为搭建云平台的yum源。
3、安装centos7.5操作系统与说明
参考之前搭建先电v2.2版本的博客：
安装CentOS7 说明与操作步骤（以controller节点为例）
4、 配置网络、主机名（controller、compute）
通过xShell远程连接工具连接【controller】节点和【compute】节点，即控制节点和计算节点。
【controller】
配置网络信息。修改相关参数信息。
[root@controller ~]# cat /etc/sysconfig/network-scripts/ifcfg-enp8s0 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes NAME=enp8s0 DEVICE=enp8s0 ONBOOT=yes IPADDR=192.168.1.10 NETMASK=255.255.255.0 GATEWAY=192.168.1.1 DNS1=192.168.1.1 [root@controller ~]# cat /etc/sysconfig/network-scripts/ifcfg-enp9s0 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes NAME=enp9s0 DEVICE=enp9s0 ONBOOT=yes IPADDR=192.168.101.10 NETMASK=255.255.255.0 GATEWAY=192.168.101.1 DNS1=192.168.101.1 [root@controller ~]# [root@controller ~]# ip address 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enp8s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 0c:c4:7a:7c:6d:16 brd ff:ff:ff:ff:ff:ff inet 192.168.1.10/24 brd 192.168.1.255 scope global noprefixroute enp8s0 valid_lft forever preferred_lft forever inet6 fe80::ec4:7aff:fe7c:6d16/64 scope link valid_lft forever preferred_lft forever 3: enp9s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 0c:c4:7a:7c:6d:17 brd ff:ff:ff:ff:ff:ff inet 192.168.101.10/24 brd 192.168.101.255 scope global noprefixroute enp9s0 valid_lft forever preferred_lft forever inet6 fe80::ec4:7aff:fe7c:6d17/64 scope link valid_lft forever preferred_lft forever [root@controller ~]# [root@controller ~]# ping -c 5 www.baidu.com PING www.a.shifen.com (180.101.49.11) 56(84) bytes of data. 64 bytes from 180.101.49.11 (180.101.49.11): icmp_seq=1 ttl=49 time=8.34 ms 64 bytes from 180.101.49.11 (180.101.49.11): icmp_seq=2 ttl=49 time=8.29 ms 64 bytes from 180.101.49.11 (180.101.49.11): icmp_seq=3 ttl=49 time=8.34 ms 64 bytes from 180.101.49.11 (180.101.49.11): icmp_seq=4 ttl=49 time=8.22 ms 64 bytes from 180.101.49.11 (180.101.49.11): icmp_seq=5 ttl=49 time=8.18 ms --- www.a.shifen.com ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4006ms rtt min/avg/max/mdev = 8.184/8.278/8.348/0.132 ms [root@controller ~]#

5、上传镜像并配置本地YUM源（controller、compute）
【controller】
配置【controller节点】的本地YUM源
[root@controller yum.repos.d]# ll total 32 -rw-r--r--. 1 root root 1664 Apr 29 2018 CentOS-Base.repo -rw-r--r--. 1 root root 1309 Apr 29 2018 CentOS-CR.repo -rw-r--r--. 1 root root 649 Apr 29 2018 CentOS-Debuginfo.repo -rw-r--r--. 1 root root 314 Apr 29 2018 CentOS-fasttrack.repo -rw-r--r--. 1 root root 630 Apr 29 2018 CentOS-Media.repo -rw-r--r--. 1 root root 1331 Apr 29 2018 CentOS-Sources.repo -rw-r--r--. 1 root root 4768 Apr 29 2018 CentOS-Vault.repo [root@controller yum.repos.d]# mkdir bak [root@controller yum.repos.d]# mv CentOS-* bak/ [root@controller yum.repos.d]# ll total 0 drwxr-xr-x. 2 root root 187 Nov 3 10:43 bak [root@controller yum.repos.d]# mv bak /home/ [root@controller yum.repos.d]# ll total 0 [root@controller ~]# vi /etc/yum.repos.d/local.repo [root@controller ~]# cat /etc/yum.repos.d/local.repo [centos] name=centos baseurl=file:///opt/centos gpgcheck=0 enabled=1 [openstack] name=openstack baseurl=file:///opt/openstack/iaas-repo gpgcheck=0 enabled=1 [root@controller ~]#
配置【compute节点】的本地YUM源，使用ftp的方式获取controller节点的YUM源。
[root@compute ~]# cd /etc/yum.repos.d/ [root@compute yum.repos.d]# ll total 32 -rw-r--r--. 1 root root 1664 Apr 29 2018 CentOS-Base.repo -rw-r--r--. 1 root root 1309 Apr 29 2018 CentOS-CR.repo -rw-r--r--. 1 root root 649 Apr 29 2018 CentOS-Debuginfo.repo -rw-r--r--. 1 root root 314 Apr 29 2018 CentOS-fasttrack.repo -rw-r--r--. 1 root root 630 Apr 29 2018 CentOS-Media.repo -rw-r--r--. 1 root root 1331 Apr 29 2018 CentOS-Sources.repo -rw-r--r--. 1 root root 4768 Apr 29 2018 CentOS-Vault.repo [root@compute yum.repos.d]# mkdir bak [root@compute yum.repos.d]# mv CentOS-* bak/ [root@compute yum.repos.d]# ll total 0 drwxr-xr-x. 2 root root 187 Nov 3 10:43 bak [root@compute yum.repos.d]# mv bak /home/ [root@compute yum.repos.d]# ll total 0 [root@compute yum.repos.d]# vi /etc/yum.repos.d/ftp.repo [root@compute yum.repos.d]# cat /etc/yum.repos.d/ftp.repo [centos] name=centos baseurl=ftp://192.168.1.10/centos gpgcheck=0 enable=1 [openstack] name=openstack baseurl=ftp://192.168.1.10/openstack/iaas-repo gpgcheck=0 enabled=1 [root@compute yum.repos.d]#
在控制节点的/opt目录下创建centos和openstack目录用来挂载centos镜像和openstack镜像
【controller】
[root@controller ~]# cd /opt/ [root@controller opt]# ll total 0 [root@controller opt]# mkdir centos [root@controller opt]# mkdir openstack [root@controller opt]# ll total 0 drwxr-xr-x. 2 root root 6 Nov 3 10:50 centos drwxr-xr-x. 2 root root 6 Nov 3 10:50 openstack [root@controller opt]#
6、挂载本地YUN源
【controller】
[root@controller ~]# ll total 8075368 -rw-------. 1 root root 1463 Nov 3 09:23 anaconda-ks.cfg -rw-r--r--. 1 root root 4470079488 Nov 3 11:04 CentOS-7-x86_64-DVD-1804.iso -rw-r--r--. 1 root root 3799093248 Nov 3 11:01 chinaskills_cloud_iaas.iso [root@controller ~]# mount -o loop CentOS-7-x86_64-DVD-1804.iso /mnt/ mount: /dev/loop0 is write-protected, mounting read-only [root@controller ~]# cp -rvf /mnt/* /opt/centos/
[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/openstack/
查看是否安装在指定的目录下。
[root@controller ~]# cd /opt/ [root@controller opt]# ll total 0 drwxr-xr-x. 8 root root 220 Nov 3 11:36 centos drwxr-xr-x. 4 root root 37 Nov 3 11:39 openstack [root@controller opt]# cd centos/ [root@controller centos]# ll total 320 -rw-r--r--. 1 root root 14 Nov 3 11:35 CentOS_BuildTag drwxr-xr-x. 3 root root 35 Nov 3 11:35 EFI -rw-r--r--. 1 root root 227 Nov 3 11:35 EULA -rw-r--r--. 1 root root 18009 Nov 3 11:35 GPL drwxr-xr-x. 3 root root 57 Nov 3 11:35 images drwxr-xr-x. 2 root root 198 Nov 3 11:35 isolinux drwxr-xr-x. 2 root root 43 Nov 3 11:35 LiveOS drwxr-xr-x. 2 root root 221184 Nov 3 11:36 Packages drwxr-xr-x. 2 root root 4096 Nov 3 11:36 repodata -rw-r--r--. 1 root root 1690 Nov 3 11:36 RPM-GPG-KEY-CentOS-7 -rw-r--r--. 1 root root 1690 Nov 3 11:36 RPM-GPG-KEY-CentOS-Testing-7 -r--r--r--. 1 root root 2883 Nov 3 11:36 TRANS.TBL [root@controller centos]# cd ..
