最小化OpenStack Train版

实验环境

主机名	IP地址	操作系统	角色
controller	10.0.0.11 、192.168.191.171	CentOS 7	控制节点、网络节点
compute1	10.0.0.31 、192.168.191.177	CentOS 7	计算节点
block1	10.0.0.41 、192.168.191.178	CentOS 7	块存储节点

1. 环境准备

1.1 基础配置

更改IP地址

关闭防火墙及SELinux

修改windowsIPv4地址

1.2 修改IP地址配置文件 controller/compute1/block1

[root@controller ~]# cp  -a /etc/sysconfig/network-scripts/ifcfg-ens33 /etc/sysconfig/network-scripts/ifcfg-ens37
[root@controller ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens37
DEVICE=INTERFACE_NAME
TYPE=Ethernet
ONBOOT="yes"
BOOTPROTO="none"
IPADDR=""
PREFIX="24"

1.3 修改域名配置文件 controller/compute1/block1

[root@controller ~]# vim /etc/hosts
# controller
10.0.0.11       controller

# compute1
10.0.0.31       compute1

# block1
10.0.0.41       block1

# object1
10.0.0.51       object1

# object2
10.0.0.52       object2

1.4 测试与互联网通信、测试（IP地址、域名）与其他节点通信

[root@block1 ~]# ping 10.0.0.11 -c2
PING 10.0.0.11 (10.0.0.11) 56(84) bytes of data.
64 bytes from 10.0.0.11: icmp_seq=1 ttl=64 time=1.18 ms

rtt min/avg/max/mdev = 0.728/0.773/0.819/0.053 ms

2. 安装网络时间协议NTP

控制节点

[root@controller ~]# yum install chrony -y
[root@controller ~]# vim /etc/chrony.conf
allow 10.0.0.0/24  
[root@controller ~]# systemctl enable chronyd.service
[root@controller ~]# systemctl start chronyd.service

其他节点

yum install chrony -y

# vim /etc/chrony.conf
##注释掉其它的server行，添加controller为NTP服务器
server controller iburst

# systemctl enable chronyd.service
# systemctl start chronyd.service

检查节点

[root@block1 ~]# chronyc sources
210 Number of sources = 1
MS Name/IP address         Stratum Poll Reach LastRx Last sample               
===============================================================================
^* controller                    3   6    77    59   +551us[  -16ms] +/-  143ms

3. 更新 OpenStack Packages controller/compute1/block1

yum install centos-release-openstack-train -y

yum upgrade -y

yum install python-openstackclient -y

yum install openstack-selinux -y
