在centos7上安装openstack mitaka版本

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
<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
    ErrorLogFormat "%{cu}t %M"
    ErrorLog /var/log/httpd/keystone-error.log
    CustomLog /var/log/httpd/keystone-access.log combined
    <Directory /usr/bin>
        Require all granted
    </Directory>
</VirtualHost>
<VirtualHost *:35357>
    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
    <Directory /usr/bin>
        Require all granted
    </Directory>
</VirtualHost>

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

将admin角色加入admin项目中创建admin role

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

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
