2.基础配置

#修改主机IP地址,主机名称,做hosts解析,关闭selinux,关闭防火墙

2.1.控制节点

#修改主机IP地址
vim /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
BOOTPROTO=static
NAME=eth0
DEVICE=eth0
ONBOOT=yes
IPADDR=10.0.0.11			##修改为指定IP地址
NETMASK=255.255.255.0
GATEWAY=10.0.0.2
DNS1=223.5.5.5
systemctl restart network 	#修改完成后重启网卡
#修改主机名称
hostnamectl set-hostname controller
bash
#做hosts解析
vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.0.11       controller
10.0.0.31       compute1

#做完hosts解析可以使用scp发送到另一台机器上
scp -rp /etc/hosts root@10.0.0.31:/etc/hosts

2.2.计算节点

#修改主机IP地址
vim /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
BOOTPROTO=static

IPADDR=10.0.0.31			##修改为指定IP地址
NETMASK=255.255.255.0
GATEWAY=10.0.0.2
DNS1=223.5.5.5
systemctl restart network 	#修改完成后重启网卡
#修改主机名称
hostnamectl set-hostname compute1
bash
#做hosts解析
vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.0.11       controller
10.0.0.31       compute1

2.4.时间同步
2.4.1控制节点

#下载安装chrony
yum -y install chrony
#修改配置文件/etc/chrony.conf
vim /etc/chrony.conf
#修改第三行
server time1.aliyun.com iburst
#修改allow
allow 10.0.0.0/24
#启动并加入开机自启
systemctl enable chronyd.service
systemctl start chronyd.service

2.4.2计算节点

#下载安装chrony
yum -y install chrony
#修改配置文件/etc/chrony.conf
vim /etc/chrony.conf
#修改第三行
server controller iburst
#启动并加入开机自启
systemctl enable chronyd.service
systemctl start chronyd.service

2.5.安装通用包

#所有节点上执行(控制节点+计算节点)
#下载openstack源
yum install centos-release-openstack-stein -y
#下载所需要的软件
yum install python-openstackclient openstack-selinux -y

2.6.安装SQL数据库

#控制节点安装即可
yum install mariadb mariadb-server python2-PyMySQL -y
vim /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 10.0.0.11
default-storage-engine = innodb
innodb_file_per_table
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
#启动并加入开机自启
systemctl enable mariadb.service
systemctl start mariadb.service
#查看端口验证
netstat -tnulp|grep 3306
#跳坑
mysql_secure_installation
回车-N-Y-Y-Y-Y

#验证端口是否存在
netstat -lntp|grep 5672
#创建用户并且设置权限
rabbitmqctl add_user openstack RABBIT_PASS
rabbitmqctl set_permissions openstack ".*" ".*" ".*"     #这里三个.*代表可读可写可配置
#安装监控插件
rabbitmq-plugins enable rabbitmq_management
#安装成功会出现15672端口
netstat -tnulp|grep 15672
#可以访问web页面查看
http://10.0.0.11:15672/
默认用户名:guest

2.17.3重建apache的dashboard配置文件

#以下两步官方文档中没有，但是需要执行，否则dashboard打不开或显示不对
cd /usr/share/openstack-dashboard
python manage.py make_web_conf --apache > /etc/httpd/conf.d/openstack-dashboard.conf

2.17.4启动

systemctl enable httpd.service
systemctl restart httpd.service
由于dashboard的运行机制是把网站下的所有文件删除之后再重新复制，所以重启httpd需要等待一段时间。
systemctl restart memcached.service

2.17.5验证

#修改window的hosts文件
C:\Windows\System32\drivers\etc\hosts文件
#添加控制节点的解析
10.0.0.11  controller
#使用浏览器访问
http://controller/dashboard或者10.0.0.11
