OpenStack Ocata三节点实验环境部署

一、测试环境准备

主机节点准备及网络规划
我物理节点是一台塔式服务器，40核CPU，64G内存，SSD盘800G，HDD盘4T。
操作系统：win7 x64
虚拟化软件：VMware WorkStation 11
系统环境准备
--最小化安装CentOS7.2系统（CentOS-7-x86_64-Minimal-1511.iso）
--关闭防火墙、关闭SELinux
```
systemctl stop firewalld.service
systemctl disable firewalld.service
```
--关闭SELinux
```
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
```
分别在三台节点上更改hostname
```
hostnamectl set-hostname controller1
hostnamectl set-hostname compute1
hostnamectl set-hostname cinder
```
然后每个节点配置/etc/hosts文件：
```
10.1.1.120 controller1
10.1.1.121 compute1
10.1.1.122 cinder
```
3.必须的软件包的安装
yum -y install ntp vim-enhanced wget bash-completion net-tools
NTP同步系统时间
ntpdate cn.pool.ntp.org
编辑ntp.conf添加时间自动同步
```
vim /etc/ntp.conf
cn.pool.ntp.org
```
搭建openstack本地yum源
见我另一篇文档OpenStack Ocata本地yum源搭建

二、安装Mariadb

安装mariadb

yum install -y mariadb-server mariadb-client`

配置mariadb

vim /etc/my.cnf.d/mariadb-openstack.cnf

添加如下内容：

[mysqld]
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8
bind-address = 10.1.1.120

3、启动数据库并设置mariadb开机启动

systemctl start mariadb.service
systemctl enable mariadb.service
systemctl status mariadb.service
systemctl list-unit-files | grep mariadb.service

初始化mariadb、设置密码
mysql_secure_installation

三、安装RabbitMQ

安装RabbitMQ
yum install -y erlang rabbitmq-server

启动MQ及设置开机启动

systemctl start rabbitmq-server.service
systemctl enable rabbitmq-server.service
systemctl status rabbitmq-server.service
systemctl list-unit-files | grep rabbitmq-server.service

创建MQ用户openstack
rabbitmqctl add_user openstack xuml26

将openstack用户赋予权限

rabbitmqctl set_permissions openstack ".*" ".*" ".*"
rabbitmqctl set_user_tags openstack administrator
rabbitmqctl list_users

验证MQ监听端口5672
```
netstat -ntlp |grep 5672
```

查看RabbitMQ插件

/usr/lib/rabbitmq/bin/rabbitmq-plugins list

打开RabbitMQ相关插件
/usr/lib/rabbitmq/bin/rabbitmq-plugins enable rabbitmq_management mochiweb webmachine rabbitmq_web_dispatch amqp_client rabbitmq_management_agent
打开相关插件后，重启下rabbitmq服务
```
systemctl restart rabbitmq-server
```
浏览器输入：http://123.45.67.120:15672 默认用户名密码：guest/guest或者openstack/xuml26
通过这个界面能很直观的看到rabbitmq的运行和负载情况

四、安装配置Keystone

openstack endpoint create --region RegionOne compute admin http://controller1:8774/v2.1/%\(tenant_id\)s

6、安装nova相关软件

yum install -y openstack-nova-api openstack-nova-conductor openstack-nova-cert openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler

7、配置nova的配置文件/etc/nova/nova.conf

cp /etc/nova/nova.conf /etc/nova/nova.conf.bak
>/etc/nova/nova.conf
openstack-config --set /etc/nova/nova.conf DEFAULT enabled_apis osapi_compute,metadata
openstack-config --set /etc/nova/nova.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 10.1.1.120
openstack-config --set /etc/nova/nova.conf DEFAULT use_neutron True
openstack-config --set /etc/nova/nova.conf DEFAULT firewall_driver nova.virt.firewall.NoopFirewallDriver
openstack-config --set /etc/nova/nova.conf DEFAULT transport_url rabbit://openstack:xuml26@controller1
openstack-config --set /etc/nova/nova.conf database connection mysql+pymysql://nova:xuml26@controller1/nova
openstack-config --set /etc/nova/nova.conf api_database connection mysql+pymysql://nova:xuml26@controller1/nova_api
openstack-config --set /etc/nova/nova.conf scheduler discover_hosts_in_cells_interval -1

openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_url http://controller1:35357
openstack-config --set /etc/nova/nova.conf keystone_authtoken memcached_servers controller1:11211
openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_type password
openstack-config --set /etc/nova/nova.conf keystone_authtoken project_domain_name default
openstack-config --set /etc/nova/nova.conf keystone_authtoken user_domain_name default
openstack-config --set /etc/nova/nova.conf keystone_authtoken project_name service
openstack-config --set /etc/nova/nova.conf keystone_authtoken username nova
openstack-config --set /etc/nova/nova.conf keystone_authtoken password xuml26
openstack-config --set /etc/nova/nova.conf keystone_authtoken service_token_roles_required True
openstack-config --set /etc/nova/nova.conf vnc vncserver_listen 10.1.1.120
openstack-config --set /etc/nova/nova.conf vnc vncserver_proxyclient_address 10.1.1.120
openstack-config --set /etc/nova/nova.conf glance api_servers http://controller1:9292
openstack-config --set /etc/nova/nova.conf oslo_concurrency lock_path /var/lib/nova/tmp

8、设置单元格cell
同步nova数据库

su -s /bin/sh -c "nova-manage api_db sync" nova
su -s /bin/sh -c "nova-manage db sync" nova

设置cell_v2关联上创建好的数据库nova_cell0

nova-manage cell_v2 map_cell0 --database_connection mysql+pymysql://root:xuml26@controller1/nova_cell0

创建一个常规cell，名字叫cell1，这个单元格里面将会包含计算节点

nova-manage cell_v2 create_cell --verbose --name cell1 --database_connection mysql+pymysql://root:xuml26@controller1/nova_cell0 --transport-url rabbit://openstack:xuml26@controller1:5672/

检查部署是否正常，这个时候肯定是会报错的，因为此时没有没有compute节点，也没有部署placement

nova-status upgrade check

创建和映射cell0，并将现有计算主机和实例映射到单元格中

nova-manage cell_v2 simple_cell_setup

查看已经创建好的单元格列表

nova-manage cell_v2 list_cells --verbose

9、安装placement
从Ocata开始，需要安装配置placement参与nova调度了，不然虚拟机将无法创建。

yum install -y openstack-nova-placement-api

创建placement用户和placement 服务

openstack user create --domain default placement --password xuml26
openstack role add --project service --user placement admin
openstack service create --name placement --description "OpenStack Placement" placement

创建placement endpoint

openstack endpoint create --region RegionOne placement public http://controller1:8778
openstack endpoint create --region RegionOne placement admin http://controller1:8778
openstack endpoint create --region RegionOne placement internal http://controller1:8778

把placement 整合到nova.conf里

openstack-config --set /etc/nova/nova.conf placement auth_url http://controller1:35357
openstack-config --set /etc/nova/nova.conf placement memcached_servers controller1:11211
openstack-config --set /etc/nova/nova.conf placement auth_type password
openstack-config --set /etc/nova/nova.conf placement project_domain_name default
openstack-config --set /etc/nova/nova.conf placement user_domain_name default
openstack-config --set /etc/nova/nova.conf placement project_name service
openstack-config --set /etc/nova/nova.conf placement username placement
openstack-config --set /etc/nova/nova.conf placement password xuml26
openstack-config --set /etc/nova/nova.conf placement os_region_name RegionOne

配置修改00-nova-placement-api.conf文件，这步没做创建虚拟机的时候会出现禁止访问资源的问题

cd /etc/httpd/conf.d/
cp 00-nova-placement-api.conf 00-nova-placement-api.conf.bak
>00-nova-placement-api.conf
vim 00-nova-placement-api.conf

添加以下内容：

Listen 8778
<VirtualHost *:8778>
WSGIProcessGroup nova-placement-api
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
WSGIDaemonProcess nova-placement-api processes=3 threads=1 user=nova group=nova
WSGIScriptAlias / /usr/bin/nova-placement-api
<Directory "/">
Order allow,deny
Allow from all
Require all granted
</Directory>
<IfVersion >= 2.4>
ErrorLogFormat "%M"
</IfVersion>
ErrorLog /var/log/nova/nova-placement-api.log
</VirtualHost>
Alias /nova-placement-api /usr/bin/nova-placement-api
<Location /nova-placement-api>
SetHandler wsgi-script
Options +ExecCGI
WSGIProcessGroup nova-placement-api
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
</Location>

重启下httpd服务

systemctl restart httpd

检查下是否配置成功

nova-status upgrade check

10、启动nova服务：

systemctl start openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstacknova-novncproxy.service
设置nova相关服务开机启动
systemctl enable openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstacknova-novncproxy.service
查看nova服务：
systemctl status openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstacknova-novncproxy.service
systemctl list-unit-files |grep openstack-nova-*

11、验证nova服务
