计算 网络  存储

操作最低配

server1  4G内存

server2  2G  内存

网络参考

https://www.cnblogs.com/shhnwangjian/p/6379640.html

server1  两块网卡 桥接

eth1

BOOTPROTO=none
DEVICE=eth1
ONBOOT=yes

ifup eth1

hostnamectl set-hostname controller

解析

172.25.11.1      controller
172.25.11.2      compute1
172.25.11.3      block1

server2

hostnamectl set-hostname  compute1

做好与真机的时间同步 chronyd

vim /etc/chrony.conf

server 172.25.11.250 iburst

allow 172.25/16

chronyc sources -v

server 1 2

server1

yum upgrade

这里禁用了 selinux

yum install mariadb mariadb-server python2-PyMySQL

/etc/my.cnf.d/openstack.cnf

[mysqld]

bind-address = 172.25.11.1

default-storage-engine = innodb
innodb_file_per_table
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

systemctl enable mariadb.service

systemctl start mariadb.service

mysql_secure_installation

mongodb 是用来计算流量收费的  这里不需要安装

消息队列的安装

yum install rabbitmq-server -y

systemctl start rabbitmq-server.service

systemctl enable  rabbitmq-server.service

rabbitmqctl add_user openstack  openstack

rabbitmqctl set_permissions openstack ".*" ".*" ".*"

rabbitmq-plugins

rabbitmq-plugins  enable rabbitmq_management

http://172.25.11.1:15672/

帐号密码  guest  guest  

memcached  作认证服务的缓存令牌

可以定义缓存时间，不用占用

yum install memcached python-memcached -y

vim /etc/sysconfig/memcached

注释最后一行

systemctl  enable    memcached

systemctl   start   memcached

openstack  keystone

使用 mysql创建

mysql -pwestos

CREATE DATABASE keystone;

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
  IDENTIFIED BY 'keystone';

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
  IDENTIFIED BY 'keystone';

将上面localhost  还为  %  在一次

openssl rand -hex 10

初始化admin token

yum install openstack-keystone httpd mod_wsgi

vim /etc/keystone/keystone.conf

[defalut]

admin_token = 99b18dca176a77a7b4b5

[database]

connection = mysql+pymysql://keystone:keystone@controller/keystone

[token]

provider = fernet

su -s /bin/sh -c "keystone-manage db_sync" keystone

mysql -pwestos

use keystone

show tables;

keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

ll /etc/keystone/

有下面就会成功

fernet-keys

启动服务apache

vim  /etc/httpd/conf/httpd.conf

/ServerName

ServerName controller

vim  /etc/httpd/conf.d/wsgi-keystone.conf

Listen 5000
Listen 35357

systemctl  enable httpd

systemctl start httpd

配置服务

yum install python-openstackclient -y

yum  upgrade

如果这个命令返回了 one or greater 的值，那么你的计算节点支持硬件加速且不需要额外的配置。

如果这个命令返回了 zero 值，那么你的计算节点不支持硬件加速。你必须配置 libvirt 来使用 QEMU 去代替 KVM

  • 在 /etc/nova/nova.conf 文件的 [libvirt] 区域做出如下的编辑：

[libvirt]
...
virt_type = qemu   

systemctl enable libvirtd.service openstack-nova-compute.service
systemctl start libvirtd.service openstack-nova-compute.service

[root@controller ~]# .  admin-openrc
[root@controller ~]# openstack compute  service list

首先admin 建立公网 public

demo下建立vm1云主机

然后  建立私网   192.168.0.0

然后建立路由  添加私网端口

再把私有网络在admin下共享出去

再次添加虚拟主机，使用私有网端
