openstack-L版安装

参照官方install document：
http://docs.openstack.org/liberty/install-guide-rdo/

实验环境：
centos7.2
桥接： 192.168.1.71 主机名：computer computer节点
nat：
桥接：192.168.1.72 主机名：controller controller节点
nat：

一、基础配置：（两台机器多要配置）

关闭selinux和iptables：
setenforce 0

iptables -F
iptables -t nat -F
systemctl stop firewalld
systemctl disable firewalld

systemctl stop NetworkManager
systemctl disable NetworkManager

设置主机名、hosts文件解析等

时间同步：controller上安装ntp服务：
yum install -y chrony
vim /etc/chrony.conf
allow 192.168.1.0/24

systemctl enable chronyd.service
systemctl start chronyd.service
#监听端口 udp123

compute上：作为时间服务器的客户端
yum install -y chrony
vim /etc/chrony.conf
server controller iburst

systemctl enable chronyd.service
systemctl start chronyd.service

使用dhclient网卡获取ip：
dhclient eno33554976
#下次使用dhclient时需要kill掉dhclient

#重启网卡命令：
systemctl restart network.service

准备阿里源、epel源：
yum install -y centos-release-openstack-liberty
yum upgrade
init 6

安装openstack 客户端和openstack-selinux
yum install -y python-openstackclient openstack-selinux

二、配置安装openstack前的基础依赖服务：

controller节点：

安装mysql：
yum install -y mariadb mariadb-server MySQL-python

写入配置文件：
vi /etc/my.cnf.d/mariadb_openstack.cnf
[mysqld]
bind-address = 192.168.1.72
default-storage-engine = innodb
innodb_file_per_table
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

设置root密码
mysql_secure_installation
设置root密码为 123456
mysql -uroot -p123456

安装nosql数据库被Telemetry service用到：
这里我们安装的是mongodb为例
yum install -y mongodb-server mongodb

编辑配置文件
vim /etc/mongod.conf
bind_ip = 192.168.1.72
smallfiles = true

启动服务
systemctl enable mongod.service
systemctl start mongod.service

安装消息队列：（端口5672）

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

添加openstack用户（rabbitmq的用户）
rabbitmqctl add_user openstack 123456
#密码 123456 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

三、安装openstack：

controller节点：

安装keystone：

tenants 租户（租房子的人可以租很多个房子）
user 用户（租房子的人）
role 角色（房子的类型）
Endpoint 服务（）
Credential 用户身份证
Authentication 认证过程
Token 钥匙

登陆mysql，创建keystone数据库：
mysql -uroot -p123456
>create database keystone;
>GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'keystone';
>GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'keystone';

安装相应的软件包：
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
vi /etc/keystone/keystone.conf
[DEFAULT]
admin_token = 123456
verbose = true #调试模式
[database]
connection = mysql://keystone:keystone@controller/keystone
#用户名：密码@主机名/库名
[memcache]
servers = localhost:11211
[token]
provider = uuid
driver = memcache
[revoke]
driver = sql

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 -pkeystone -hcontroller -t keystone -e "show tables"

配置httpd：
先编辑配置文件 /etc/httpd/conf/httpd.conf
ServerName controller

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

Listen 5000
Listen 35357
<VirtualHost *:5000>
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
<IfVersion >= 2.4>
ErrorLogFormat "%{cu}t %M"
</IfVersion>
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</Directory>
</VirtualHost>

启动httpd：
systemctl enable httpd.service
systemctl start httpd.service

创建服务实例：

首先设置环境变量：
export OS_TOKEN=123456
export OS_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3

检查环境变量：
echo $OS_IDENTITY_API_VERSION

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

创建admin用户（密码为123456、要输入的）
openstack user create --domain default --password-prompt admin

创建admin角色
openstack role create admin

给admin租户和用户赋予admin的角色
openstack role add --project admin --user admin admin

创建一个service 租户（后面用到）
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1234567）
openstack user create --domain default --password-prompt demo

创建角色user
openstack role create user

给demo租户和demo用户赋予demo角色
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：
vi /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（密码123456、1234567）
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

创建admin用户变量：

controller节点：

安装network：

Networking又叫做Neutron，是Openstack必不可少的组件，它其实是网络虚拟化的实现工具，可以让我们模拟出路由器、交换机、网卡等网络设备。
Neutron支持两种网络模式，
第一种是非常简单的网络架构，它仅支持是让实例连接外网，不支持自定义网络、路由器以及浮动ip。只有管理员或者授权的用户有权限去管理网络。
第二种网络功能比较强大，支持自定义网络管理，支持自建路由器并且也支持浮动ip。即使没有授权的用户也可以管理网络，支持用户自己配置和管理。

创建库、授权账号 mysql -uroot -p123456
> CREATE DATABASE neutron;
> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'neutron';
> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'neutron';

执行脚本
source admin.sh

创建neutron用户（密码为123456）

controller节点：

controller：
对象存储：cinder

controller节点：

命令行操作：
创建实例：

创建网络：
先停止vmwork 的dhcp服务：

执行初始化脚本
source admin.sh

创建网络
neutron net-create public --shared --provider:physical_network public \
--provider:network_type flat

创建子网
neutron subnet-create public 192.168.1.0/24 --name public \
--allocation-pool start=192.168.1.10,end=192.168.1.30 \
--dns-nameserver 119.29.29.29 --gateway 192.168.1.1
说明：这里的公网，实际上是虚拟机用的那个网段，
我们暂时把它作为公网，在这里因为涉及到dhcp服务，
会和局域网内的路由器上的dhcp服务产生冲突，所以需要先把路由器上的dhcp服务关掉。

创建key：

执行初始化脚本
source demo.sh
生成密钥
ssh-keygen -q -N ""
nova keypair-add --pub-key ~/.ssh/id_rsa.pub mykey
验证密钥
nova keypair-list
增加安全组规则
nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
允许ssh 访问
nova secgroup-add-rule default tcp 22 22 0.0.0.0/0

创建虚拟机实例：

执行初始化脚本
source demo-openrc.sh
列出实例类型
nova flavor-list
列出所有镜像
nova image-list
列出可用网络
neutron net-list
列出安全组
nova secgroup-list
运行实例
nova boot --flavor m1.tiny --image cirros --nic net-id=PUBLIC_NET_ID \
--security-group default --key-name mykey public-instance
说明：这里的PUBLIC_NET_ID需要替换为可用网络里面public网络的id

检测实例状态
nova list

使用vnc连接（使用下面命令可以列出vnc的连接）
nova get-vnc-console public-instance novnc
#会返回一个http连接，在浏览器中打开

验证网络（在实例里面）
ping -c 4 192.168.1.1
ping www.baidu.com

远程连接实例
首先用nova list 查看实例的ip（假如为192.168.1.13）
验证ip
ping -c4 192.168.1.33
远程ssh登录 ssh cirros@192.168.16.33
