前言：openstack真是一个庞然大物，想要吃透还真不容易，所以在对openstack大概有了一个了解的时候，就应该是部署，虽然openstack的安装方式有rdo或者devstack等一键安装工具，但是最好浅尝辄止，有了大概的使用经验之后就应该是从头到尾的安装一遍了，不然对于那些报错，以及故障的解决一定是不够气定神闲的，因此，当你有了openstack的基本认识后，开始安装吧~

注：openstack的官方文档写得真的是，好的不要不要的，但是看英文总是感觉有点不溜，因此在官方文档的基础上写得这篇笔记。
参考:http://docs.openstack.org/mitaka/install-guide-rdo/
首先应该是大概的规划，需要几个节点，选择什么操作系统，网络怎么划分~
下面是我的大概规划
节点数：2 (控制节点，计算节点)
操作系统：CentOS Linux release 7.2.1511 (Core)
网络配置：
控制节点： 10.0.0.101 192.168.15.101
结算节点： 10.0.0.102 192.168.15.102
先决条件：
The following minimum requirements should support a proof-of-concept environment with core services and several CirrOS instances:
Controller Node: 1 processor, 4 GB memory, and 5 GB storage
Compute Node: 1 processor, 2 GB memory, and 10 GB storage
官方建议概念验证的最小硬件需求。
控制节点 1 处理器，4 GB内存，5 GB硬盘
计算节点 1 处理器，2 GB内存，10 GB硬盘
参考：http://docs.openstack.org/mitaka/install-guide-rdo/environment.html
注：如果你是用手动一步一步的创建操作系统，配置网络，那么笔者就得好好的鄙视你了~~研究研究vagrant吧，通过下面的配置文件你就能一条命令生成两个虚拟机，并配置好网络了，vagrant简易教程参考：http://youerning.blog.51cto.com/10513771/1745102
# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure(2) do |config|
config.vm.box = "centos7"
node_servers = { :control => ['10.0.0.101','192.168.15.101'],
:compute => ['10.0.0.102','192.168.15.102']
}
node_servers.each do |node_name,node_ip|
config.vm.define node_name do |node_config|
node_config.vm.host_name = node_name.to_s
node_config.vm.network :private_network,ip: node_ip[0]
node_config.vm.network :private_network,ip: node_ip[1],virtualbox_inet: true
config.vm.boot_timeout = 300
node_config.vm.provider "virtualbox" do |v|
v.memory = 4096
v.cpus = 1
end
end
end
end
通过vagrant up一条命令，稍等一会，两个热腾腾的虚拟机就出炉了，我们的环境就OK了~~
环境如下
操作系统：CentOS Linux release 7.2.1511 (Core)
网络配置：
控制节点： 10.0.0.101 192.168.15.101
结算节点： 10.0.0.102 192.168.15.102
注意：上面的config.vm.box = "centos7"，首先需要有个centos7的box
在开始部署前，我们先捋一捋openstack安装步骤
首先是软件环境准备，我们需要将一些通用的软件以及源仓库等进行配置，基本如下
NTP服务器
控制节点，其他节点
openstack 安装包仓库
通用组件：
SQL 数据库 ===> MariaDB
NOSQL 数据库 ==> MongoDB(基本组件不需要，)
消息队列 ==> RabbitMQ
Memcached
再就是openstack整个框架下的各个组件，基本组件如下
认证服务 ===> Keystone
镜像服务 ===> Glance
计算资源服务 ===> Nova
网络资源服务 ===> Neutron
Dashboard ===> Horizon
块存储服务 ===> Cinder
其他存储服务，如下
文件共享服务 ===> Manila
对象存储服务 ===> Swift
其他组件，如下
编排服务 ===> Heat
遥测服务 ===> Ceilometer
数据库服务 ===> Trove
环境准备
域名解析：
在各个节点编辑hosts文件,加入以下配置
10.0.0.101 controller
10.0.0.102 compute
ntp时间服务器
控制节点
1) 安装chrony软件包
yum install chrony
2) 编辑配置文件 /etc/chrony.conf，添加以下内容，202.108.6.95可根据自己需求自行更改。
server 202.108.6.95 iburst
allow 10.0.0.0/24
3)加入自启动，并启动
# systemctl enable chronyd.service
# systemctl start chronyd.service
其他节点
1) 安装chrony软件包
yum install chrony
2) 编辑配置文件 /etc/chrony.conf，添加以下内容
server controller iburst
allow 10.0.0.0/24
3)加入自启动，并启动
# systemctl enable chronyd.service
# systemctl start chronyd.service
验证：
控制节点
chronyc sources
210 Number of sources = 2
MS Name/IP address Stratum Poll Reach LastRx Last sample
=============================================================
^- 192.0.2.11 2 7 12 137 -2814us[-3000us] +/- 43ms
^* 192.0.2.12 2 6 177 46 +17us[ -23us] +/- 68ms
其他节点
# chronyc sources
210 Number of sources = 1
MS Name/IP address Stratum Poll Reach LastRx Last sample
===============================================================================
^* controller 3 9 377 421 +15us[ -87us] +/- 15ms
openstack 安装包仓库
安装相应openstack版本yum源
yum install centos-release-openstack-mitaka
系统更新
yum upgrade
注：如果系统内核有更新，需要重启
安装openstackclient，openstack-selinux
yum install python-openstackclient
yum install openstack-selinux
注：如果报什么 Package does not match intended download，则yum clean all或者直接下载rpm包安装吧。
参考下载地址：http://ftp.usf.edu/pub/centos/7/cloud/x86_64/openstack-kilo/common/
SQL数据库
安装
yum install mariadb mariadb-server python2-PyMySQL
创建/etc/my.cnf.d/openstack.cnf配置文件，加入以下内容
#绑定IP
[mysqld]
bind-address = 10.0.0.11
#设置字符集等
default-storage-engine = innodb .
innodb_file_per_table
collation-server = utf8_general_ci
character-set-server = utf8
配置启动项，启动等
systemctl enable mariadb.service
systemctl start mariadb.service
数据库初始化，创建root密码等，操作如下
mysql_secure_installation
Enter current password for root (enter for none):[Enter]
Set root password? [Y/n] Y
New password: openstack
Re-enter new password:openstack
Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] n
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y
消息队列rabbitmq
安装
yum install rabbitmq-server
配置启动项，启动
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
添加openstack用户
rabbitmqctl add_user openstack RABBIT_PASS
设置openstack用户的权限，依次分别为写，读，访问
rabbitmqctl set_permissions openstack ".*"".*"".*"
NoSQL Mongodb
安装
yum install mongodb-server mongodb
配置/etc/mongod.conf配置文件
bind_ip = 10.0.0.11
#smallfile=true可选
smallfiles = true
配置启动项，启动
# systemctl enable mongod.service
# systemctl start mongod.service
Memcached
安装
# yum install memcached python-memcached
配置启动项，启动
# systemctl enable memcached.service
# systemctl start memcached.service
至此，openstack整个框架的软件环境基本搞定，下面就是各组件了。
安装各组件很有意思，除了keystone基本上是差不多的步骤，唯一的区别就是创建时指定的名字不同而已，基本是一般以下步骤。
1)配置数据库
create database xxx
GRANT ALL PRIVILEGES ON keystone.* TO 'xxxx'@'localhost' \
IDENTIFIED BY 'XXXX_DBPASS';
GRANT ALL PRIVILEGES ON keystone.* TO 'xxxx'@'%' \
IDENTIFIED BY 'XXXX_DBPASS';
2)安装
yum install xxx
3)配置文件
配置各项服务的连接,比如数据库，rabbitmq等
认证配置
特定配置
5)数据库同步
创建需要的表
4)加入启动项，启动
# systemctl enable openstack-xxx.service
# systemctl start openstack-xxxx.service
5)创建用户，service，endpoint等
openstack user create xxx
openstack service create xxx
openstack endpoint create xxx
6)验证服务是否成功
注：配置文件的配置建议首先备份，然后为了省略不必要的篇幅，在此说明配置文件的编辑方式，如下。
[DEFAULT]
...
admin_token = ADMIN_TOKEN
上面的内容，指明在[DEFAULT]的段落加入admin_token = ADMIN_TOKEN内容。
各组件安装
认证服务 Keystone
配置数据库
$ mysql -u root -p
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY 'KEYSTONE_DBPASS';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY 'KEYSTONE_DBPASS';
安装
# yum install openstack-keystone httpd mod_wsgi
配置文件/etc/keystone/keystone.conf
admin令牌
[DEFAULT]
...
admin_token = ADMIN_TOKEN
数据库
[database]
...
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone
令牌生成方式
[token]
...
provider = fernet
注：上面的ADMIN_TOKEN可用openssl rand -hex 10命令生成，或者填入一串自定义的字符串
数据库同步
# su -s /bin/sh -c "keystone-manage db_sync" keystone
初始化fernet秘钥。
令牌的生成方式参考：http://blog.csdn.net/miss_yang_cloud/article/details/49633719
# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
配置Apache
编辑/etc/httpd/conf/httpd.conf
更改一下内容
ServerName controller
创建/etc/httpd/conf.d/wsgi-keystone.conf配置文件，加入以下内容
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
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
Require all granted
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
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
Require all granted
配置启动项，启动
# systemctl enable httpd.service
# systemctl start httpd.service
创建service，API endpoint
为了避免不必要的篇幅，将admin_token，endpoint url配置到环境变量。
$ export OS_TOKEN=ADMIN_TOKEN
$ export OS_URL=http://controller:35357/v3
$ export OS_IDENTITY_API_VERSION=3
创建service
$ openstack service create \
--name keystone --description "OpenStack Identity" identity
创建endpoint，依次有public，internal，admin
$ openstack endpoint create --region RegionOne \
identity public http://controller:5000/v3
$ openstack endpoint create --region RegionOne \
identity internal http://controller:5000/v3
$ openstack endpoint create --region RegionOne \
identity admin http://controller:35357/v3
创建域，项目，用户，角色 domain,project,user,role
创建domain
openstack domain create --description "Default Domain" default
创建project
openstack user create --domain default \
--password-prompt admin
创建admin role
openstack role create admin
将admin角色加入admin项目中
openstack role add --project admin --user admin admin
创建service项目
openstack project create --domain default \
--description "Service Project" service
创建demo项目
openstack project create --domain default \
--description "Demo Project" demo
创建demo用户
openstack user create --domain default \
--password-prompt demo
创建user角色
openstack role create user
将user角色加入到demo项目中
openstack role add --project demo --user demo user
注：记住创建用户时的密码。
验证admin用户
unset OS_TOKEN OS_URL
openstack --os-auth-url http://controller:35357/v3 \
--os-project-domain-name default --os-user-domain-name default \
--os-project-name admin --os-username admin token issue

如果有以上格式返回，验证通过
admin，demo用户的环境变量脚本
正常情况下，当然吧诸如os-xxxx的参数放在环境变量中，为了更快的在admin，demo用户之间切换，创建环境脚本
创建admin-openrc
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=ADMIN_PASS
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
创建demo-openrc
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=DEMO_PASS
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
在此验证admin
首先 . admin-openrc

GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
IDENTIFIED BY 'CINDER_DBPASS';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
IDENTIFIED BY 'CINDER_DBPASS';
创建service，user，role
$ . admin-openrc
$ openstack user create --domain default --password-prompt cinder
$ openstack role add --project service --user cinder admin
注意，这里创建两个service
$ openstack service create --name cinder \
--description "OpenStack Block Storage" volume
$ openstack service create --name cinderv2 \
--description "OpenStack Block Storage" volumev2
创建endpoint，依次有public，internal，admin
$ openstack endpoint create --region RegionOne \
volume public http://controller:8776/v1/%\(tenant_id\)s
$ openstack endpoint create --region RegionOne \
volume internal http://controller:8776/v1/%\(tenant_id\)s
$ openstack endpoint create --region RegionOne \
volume admin http://controller:8776/v1/%\(tenant_id\)s
注意，每个service对应三个endpoint
$ openstack endpoint create --region RegionOne \
volumev2 public http://controller:8776/v2/%\(tenant_id\)s
$ openstack endpoint create --region RegionOne \
volumev2 internal http://controller:8776/v2/%\(tenant_id\)s

至此。基本上完成了，所有的安装，你可以在dashboard上首先用admin用户创建一个网络，然后用新建一个实例
后记：虽然手动安装一整套实在有点夸张，这里还是用yum的呢~但是至少得这么手动来一次，其他时候就脚本或者安装工具吧，复制粘贴都把我复制的眼花了~
其他组件就另起一篇文章了，值得注意的是，官方文档才是最好的文档
本文题目：在centos7上安装openstackmitaka版本
