Cloud computing infrastructure platform to build (the first electric version)

1. Environment

prepare in advance

1. install the operating system CentOS7, note left partition portion installed blank
2. questions require computing node and a control node arranged hostname

# hostnamectl set-hostname controller

3. dividing partition

#compute节点
[root@compute] # parted /dev/md126
(parted) mkpart swift 500G 600G //创建swift分区，从500G到600G
[root@compute] # mkfs.xfs /dev/md126p5  //格式化分区

4. Configure NIC
# Title two general requirements for the card
controller & compute two nodes need to be the operation

控制节点
网卡1 ：192.168.100.10
网卡2 ：192.168.200.10

计算节点
网卡1 ：192.168.100.20
网卡2 ：192.168.200.20

Modify the network card configuration file

vi /etc/sysconfig/network-scripts/ifcfg-eth0
修改以下参数
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.100.10
NETMASK=255.255.255.0
GATEWAY=192.168.100.1

vi /etc/sysconfig/network-scripts/ifcfg-eth1
修改以下参数
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.200.10 
NETMASK=255.255.255.0
第二张网卡（一定不能配置网关）

5. Configure the local source yum

• Image file uploading provided, mount (only needs to be done in the controller node)

  #挂载CentOS系统iso文件
  [root@controller ~]# mkdir /opt/{centos,iaas}  //创建挂载点文件夹
  [root@controller ~]# mount  CentOS-7-x86_64-DVD-1511.iso  /opt/centos
  [root@controller ~]# mount XianDian-IaaS-v2.1.iso  /opt/iaas
  df -hT  查看挂载状态

• Modify yum source configuration

  
  #控制节点的文件内容
  [centos]
  name=centos
  baseurl=file:///opt/centos
  gpgcheck=0
  enabled=1
  [iaas]
  name=iaas
  baseurl=file:///opt/iaas-repo
  gpgcheck=0
  enabled=1

# Compute nodes file content
[CentOS]
name = CentOS
BaseURL = FTP: //192.168.100.10/centos
gpgcheck = 0
Enabled =. 1
[IaaS]
name = IaaS
BaseURL = FTP: //192.168.100.10/iaas-repo
gpgcheck = 0
Enabled. 1 =

 - 执行以下命令
```bash
#yum clean all
#yum update

6.controller node installation ftp

[root@controller ~]# yum install vsftpd –y
#在controller节点搭建ftp服务器,并把opt目录作为ftp目录的共享根目录（修改ftp配置文件）
[root@controller ~]# vi /etc/vsftpd/vsftpd.conf
#任意位置添加anon_root=/opt/
[root@controller ~]# systemctl start vsftpd
[root@controller ~]# systemctl enable vsftpd
#重启ftp并加入开机自启

7. Close the firewall (perform all nodes)

systemctl stop firewalld
systemctl disable firewalld

8. All nodes installed scripts package to provide electricity

yum install iaas-xiandian -y

we /etc/xiandian/openrc.sh

HOST_IP=192.168.100.10
HOST_NAME=controller
HOST_IP_NODE=192.168.100.20
HOST_NAME_NODE=compute

CEILOMETER_PASS=000000
AODH_DBPASS=000000
AODH_PASS=000000

9. All nodes perform pre-deployment script

iaas-pre-host.sh

10. Modify ntp time synchronization configuration
controller node
delete the default server configuration, add the following configuration

server 127.127.1.0
fudge 127.127.1.0 stratum 10

• controller node restart ntp service and add the boot from Kai

[root@controller ~]# systemctl start ntpd
[root@controller ~]# systemctl enable ntpd

• compute nodes execute the following command

[root@compute ~]# ntpdate controller

11. Restart all nodes in the server

#reboot

3.controller mirror service node installation glance

4. upload image (this step can be completed at a later Dashboard installation, web pages operation)

#加载配置文件
[root@controller ~]# source /etc/keystone/admin-openrc.sh
#创建镜像
[root@controller ~]# glance image-create --name "CentOS7.0" --disk-format qcow2 --container-format bare --progress < /opt/images/centos_7-x86_64_xiandian.qcow2

• Create a network and cloud hosting, you can fill in the relevant parameters by subject
  (1) Create a network administrator → Network → (ext-net) → create subnets (EXT-Subnet)
  (2) Project → New → Network → routing routing Add → gateway and network adapter
  (3) to calculate the project → → → access security management rules → Add rules (ICMP, TCP, UDP)
  (4) to calculate the project → → → cloud hosting cloud hosting to create a floating IP bindings →
