一、安装前的准备

在RHEL7/CentOS7上安装openstack  liberty

两台虚拟机,安装centos7系统(准备两个网卡,一个NAT,另一个仅主机)

nat网卡设置ip,可以联网,仅主机的网卡只要我们windows可以通就行,主要是用putty远程连接的

关闭selinux

关闭iptables

systemctl stop firewalld

systemctl disable firewalld

关闭NetworkManager 

systemctl stop NetworkManager

systemctl disable NetworkManager

二、配置密码

在部署openstack过程中会在多个地方使用到密码,为了方便管理和安全设置,我们需要提前先定义好密码,使用命令mkpasswd -s 0生成随机字符串


Database password (no variable used)Root password for the database   tn1Pi6Ytm

ADMIN_PASSPassword of user admin    3qiVpzU2x

CEILOMETER_DBPASSDatabase password for the Telemetry service  Czn3bF1hm

CEILOMETER_PASSPassword of Telemetry service user ceilometer  abquh12GU 

CINDER_DBPASSDatabase password for the Block Storage service O3bwbpoZ3

CINDER_PASSPassword of Block Storage service user cinder  hf8LX9bow

DASH_DBPASSDatabase password for the dashboard  5qBZxnn1g

DEMO_PASSPassword of user demo   9TtbgaA1q

GLANCE_DBPASSDatabase password for Image service  Zznky4tP0

GLANCE_PASSPassword of Image service user glance   Wuyaf4cV6

HEAT_DBPASSDatabase password for the Orchestration service  b7Fk5wjLg

HEAT_DOMAIN_PASSPassword of Orchestration domain  7Gotb3eoH

HEAT_PASSPassword of Orchestration service user heat  eqQ2jLgz0

KEYSTONE_DBPASSDatabase password of Identity service  f6zx0gURv

NEUTRON_DBPASSDatabase password for the Networking service   quidyOC50

NEUTRON_PASSPassword of Networking service user neutron  mdcGVl29i

NOVA_DBPASSDatabase password for computer service RYgv0rg7p

NOVA_PASSPassword of computer service user nova  hsSNsqc43

RABBIT_PASSPassword of user guest of RabbitMQ  o3NXovnz5

SWIFT_PASSPassword of Object Storage service user swift  6ci5xWOdk

METADATA_SECRET      m8uhmQTu2

三、配置ip(一个nat模式,一个仅主机模式,仅主机的网卡只需要给xshell连接即可)

在controller上

dhclient eno16777736 (nat卡)

dhclient -r 

dhclient eno 33554984 (仅主机卡)

ifconfig 查看ip

vim /etc/sysconfig/network-scripts/ifcfg-eno16777736 

TYPE=Ethernet

BOOTPROTO=static

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

NAME=eno16777736

UUID=6612a6a5-090b-43b8-9c87-e43545f800a9

DEVICE=eno16777736

ONBOOT=yes

IPADDR=192.168.163.249

PREFIX=24

GATEWAY=192.168.163.2

PEERDNS=no

在computerr上  

dhclient eno16777736 (nat卡)

dhclient -r 

dhclient eno 33554984 (仅主机卡)

修改dns配置文件 

vim /etc/resolv.conf

nameserver 10.10.19.3

ifconfig 查看ip

vim /etc/sysconfig/network-scripts/ifcfg-eno16777736

vim /etc/resolv.conf

nameserver 10.10.19.3

TYPE=Ethernet

BOOTPROTO=dhcp

DEFROUTE=yes

PEERDNS=yes

PEERROUTES=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

NAME=eno16777736

UUID=a0761a5d-3a3d-420b-82b8-cd5e2919c55a

DEVICE=eno16777736

ONBOOT=yes

IPADDR=192.168.163.246

PREFIX=24

GATEWAY=192.168.163.2

PEERDNS=no

修改dns配置文件 

vim /etc/resolv.conf

nameserver 10.10.19.3

修改后使用客户端ssh远程连接,如果连接密码跳出比较慢,修改以下配置文件 

vim /etc/ssh/sshd.conf

找到#USEDNS yes

改成USEDNS no

四、两台机器,设置hostname,配置时间同步

hostnamectl set-hostname controller

hostnamectl set-hostname computerr

编辑/etc/hosts: 192.168.163.249  controller 

                 192.168.163.246  computerr

controller上:

yum install -y chrony 

vim /etc/chrony.conf

增加或更改:  allow 192.168.163.0/24

保存后,执行systemctl enable chronyd.service

systemctl start chronyd.service

computer上:

yum install -y chrony;vim /etc/chrony.conf

增加或更改: server controller iburst

保存后,执行systemctl enable chronyd.service

systemctl start chronyd.service

五、配置yun源升级软件安装openstack需要的包

安装openstack的yum源(两个机器上都操作)

yum install -y centos-release-openstack-liberty



升级所有的包(两个机器上都操作)

yum upgrade   

结束后重启系统


安装openstack 客户端和openstack-selinux

yum install -y python-openstackclient   openstack-selinux

六、安装sql服务(controller)

yum install  -y mariadb mariadb-server MySQL-python

编辑配置文件 vim /etc/my.cnf.d/mariadb_openstack.cnf  #加入下面内容

[mysqld]

bind-address = 192.168.163.249

default-storage-engine = innodb

innodb_file_per_table #表示一个表对应一个文件

collation-server = utf8_general_ci

init-connect = 'SET NAMES utf8'

character-set-server = utf8

启动mariadb:systemctl enable mariadb.service

systemctl start mariadb.service

安全配置,设置root密码

mysql_secure_installation

设置root密码为  tn1Pi6Ytm #此处密码为第二步用mkpasswd生成的密码

需要确定的全部为y

使用mysql -uroot -ptn1Pi6Ytm 测试是否可以登陆

七、安装nosql(control)如果架构不需要用到可以不安装


nosql数据库被Telemetry service用到

在这里我们安装的是mongodb

yum install -y  mongodb-server mongodb


编辑配置文件  vim  /etc/mongod.conf  #更改如下配置

bind_ip = 192.168.163.249

smallfiles = true


启动服务

systemctl enable mongod.service

systemctl start mongod.service


八、安装消息队列(controller)


rabbitmq消息队列服务在openstack中起到非常关键的作用,它好比是一个交通枢纽,各个组件之间的通信由它来完成。

yum install -y  rabbitmq-server

启动rabbitmq-server服务

systemctl enable rabbitmq-server

systemctl start rabbitmq-server

使用ps aux |grep rabbitmg 和netstat -lnp |grep 5672确定有没有启动

添加openstack用户

rabbitmqctl add_user openstack   o3NXovnz5

# 密码 o3NXovnz5   用户名为openstack

为openstack用户授权

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

允许openstack用户可以配置,可以写,可以读


九、增加identity - keystone介绍(controller)

identity即keystone,它是openstack的验证中心,所有的服务都由它来认证。参考 http:#blog.csdn.net/wsfdl/article/details/20492343

在keyston中有以下角色:tenants(租户或项目)、用户、角色、服务目录和端点


如果把宾馆比作为Tenant,住宿的人就是User ,宾馆可以提供多种诸如住宿、娱乐、饮食等多种服务(Service),具体来说,住宿是一种具体的服务(Endpoint)。就住宿而言,有普通间和总统套房,如果你的VIP等级(Role)高,你可以享受到豪华的总统套房。入住前,我们需要拿×××开房(Credential),认证×××不是冒牌货后(Authenticaiton),会给你一个×××(Token),然后你拿着×××,就可以进入房间和享受各种服务。


以创建一个虚拟机(server)为例,keystone在openstack的访问流程大致如下:

1 用户Alice通过自己的户名和密码向keystone申请token,keystone认证用户名和密码后,返回token1

2 Alice通过token1发送keystone查询他所拥有的租户,keystone验证token1成功后,返回Alice的所有Tenant

3 Alice选择一个租户,通过用户名和密码申请token,keystone认证用户名、密码、tenant后,返回token2。(其实1、2步仅仅是为了查询tenant,如果已经知道tenant,可以忽略1、2步)

4 Alice通过token2发送创建server的请求,keystone验证token2(包括该token是否有效,是否有权限创建虚拟机等)成功后,然后再把请求下发到nova,最终创建虚拟机


登陆mysql,创建数据库

mysql -uroot -ptn1Pi6Ytm

>create database keystone;

>GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost'    IDENTIFIED BY 'f6zx0gURv';

>GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%'    IDENTIFIED BY 'f6zx0gURv';

说明,创建一个keystone库,并且授权给keystone用户所有权限,密码为f6zx0gURv

安装相关的包

yum install -y openstack-keystone httpd mod_wsgi   memcached python-memcached

启动memcached服务

systemctl enable memcached.service

systemctl start memcached.service


编辑keystone配置文件

vim  /etc/keystone/keystone.conf  #修改或增加配置如下

[DEFAULT]

admin_token = 3qiVpzU2x

verbose = true #启动时记录相关日志 

[database]

connection = mysql:#keystone:f6zx0gURv@controller/keystone #mysql(数据库类型)keystone(用户名)f6zx0gURv(密码)controller(登陆的服务器)keystone(进入的数据库)

[memcache]

servers = localhost:11211

[token]

provider = uuid

driver = memcache

[revoke]

driver = sql


增加identity - 导入数据(controller)

导入keystone相关的数据

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

这里会有个提示  No handlers could be found for logger "oslo_config.cfg"  忽略它,不影响

检查有没有正常导入数据:

mysql -ukeystone -pf6zx0gURv -hcontroller -t keystone  -e  "show tables"  看是否有列出表来,如果是空,说明没有成功导入数据


配置apache

先编辑配置文件 /etc/httpd/conf/httpd.conf

增加或更改 

ServerName controller


增加identity - 配置httpd子配置文件(controller)

编辑配置文件  vim /etc/httpd/conf.d/wsgi-keystone.conf  内容如下


Listen 5000

Listen 35357

WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}

WSGIProcessGroup keystone-public

WSGIScriptAlias / /usr/bin/keystone-wsgi-public

WSGIApplicationGroup %{GLOBAL}

WSGIPassAuthorization On

= 2.4>

ErrorLogFormat "%{cu}t %M"

ErrorLog /var/log/httpd/keystone-error.log

CustomLog /var/log/httpd/keystone-access.log combined

= 2.4>

Require all granted

Order allow,deny

Allow from all

WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}

WSGIProcessGroup keystone-admin

WSGIScriptAlias / /usr/bin/keystone-wsgi-admin

WSGIApplicationGroup %{GLOBAL}

WSGIPassAuthorization On

= 2.4>

ErrorLogFormat "%{cu}t %M"

ErrorLog /var/log/httpd/keystone-error.log

CustomLog /var/log/httpd/keystone-access.log combined

= 2.4>

Require all granted

Order allow,deny

Allow from all


启动apache

systemctl enable httpd.service

systemctl start httpd.service


增加identity - 创建服务实例(controller)



首先设置环境变量:

export OS_TOKEN=3qiVpzU2x

export OS_URL=http:#controller:35357/v3

export OS_IDENTITY_API_VERSION=3

然后创建服务实例

openstack service create   --name keystone --description "OpenStack Identity" identity

创建端点

openstack endpoint create --region RegionOne   identity public http:#controller:5000/v2.0

openstack endpoint create --region RegionOne   identity internal http:#controller:5000/v2.0

openstack endpoint create --region RegionOne   identity admin http:#controller:35357/v2.0

创建租户(tenants)、用户以及角色

创建admin 租户

openstack project create --domain default   --description "Admin Project" admin

创建admin用户 (密码为3qiVpzU2x)

openstack user create --domain default   --password-prompt admin 


创建admin角色

openstack role create admin

添加admin角色到admin租户和用户

openstack role add --project admin --user admin admin

下面我们再来创建一个service 租户

openstack project create --domain default   --description "Service Project" service

创建demo租户

openstack project create --domain default   --description "Demo Project" demo

创建demo用户 (密码9TtbgaA1q)

openstack user create --domain default   --password-prompt demo

创建user角色

openstack role create user

添加user角色到demo租户和demo用户

openstack role add --project demo --user demo user


验证admin用户和demo用户是否能正常登陆

首先做一个安全设置:

vim /usr/share/keystone/keystone-dist-paste.ini

搜索admin_token_auth, 从[pipeline:public_api], [pipeline:admin_api]和[pipeline:api_v3]中,把admin_token_auth去掉,例如把

pipeline = sizelimit url_normalize request_id build_auth_context token_auth admin_token_auth json_body ec2_extension user_crud_extension public_service

改为

pipeline = sizelimit url_normalize request_id build_auth_context token_auth json_body ec2_extension user_crud_extension public_service


取消环境变量OS_TOKEN和OS_URL

unset  OS_TOKEN OS_URL

然后再登陆admin和demo用户

openstack --os-auth-url http:#controller:35357/v3   --os-project-domain-id default --os-user-domain-id default   --os-project-name admin --os-username admin --os-auth-type password   token issue

openstack --os-auth-url http:#controller:5000/v3   --os-project-domain-id default --os-user-domain-id default   --os-project-name demo --os-username demo --os-auth-type password   token issue


增加identity - 验证操作(controller)


创建openstack客户端脚本

vi admin-openrc.sh   //内容

export OS_PROJECT_DOMAIN_ID=default

export OS_USER_DOMAIN_ID=default

export OS_PROJECT_NAME=admin

export OS_TENANT_NAME=admin

export OS_USERNAME=admin

export OS_PASSWORD=3qiVpzU2x

export OS_AUTH_URL=http://controller:35357/v3

export OS_IDENTITY_API_VERSION=3


执行脚本

source admin-openrc.sh

申请认证令牌
