openstack部署
环境准备
1、openstack部署 - 硬件要求
实验环境：至少两台机器。
Controller Node: 1 processor, 2 GB memory, and 5 GB storage
Compute Node: 1 processor, 2 GB memory, and 10 GB storage
2、openstack部署 - 前期准备
关闭selinux
setenforce 0
关闭iptables
systemctl dissystemctl stop firewalld
able firewalld
关闭NetworkManager
systemctl stop NetworkManager
systemctl disable NetworkManager
3、两台机器，设置hostname
hostnamectl set-hostname controller
hostnamectl set-hostname compute
4、编辑/etc/hosts：
192.168.100.20 controller
192.168.100.21 compute
5、同步时间：
controller上：
yum install -y chrony
vim /etc/chrony.confl
增加或更改：allow 192.168.16.0/24
systemctl enablechronyd.service
systemctl start chronyd.service
compute上：lyum install -y chrony
vim /etc/chrony.conf
增加或更改： server controller iburst
systemctl enablechronyd.service
systemctl start chronyd.service
部署阶段
1、安装openstack的yum源（两个机器上都操作）
yum install -y centos-release-openstack-liberty
2、升级所有的包（两个机器上都操作）
yum upgrade ####结束后重启系统reboot
安装openstack 客户端和openstack-selinux
yum install -y python-openstackclient openstack-selinux
controller部署
1、sql服务安装
yum install -y mariadb mariadb-server MySQL-python
编辑配置文件
vi /etc/my.cnf.d/mariadb_openstack.cnf //加入下面内容
[mysqld]
bind-address = 192.168.100.20
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
安全配置，设置root密码
命令行执行：mysql_secure_installation
设置root密码为：root
2、安装nosql
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 vi /etc/mongod.conf //更改如下配置
bind_ip = 192.168.100.20
smallfiles = true
启动服务
systemctl enable mongod.service
systemctl start mongod.service
3、安装消息队列
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
rabbitmqctl add_user openstack openstackpasswd
// 密码 openstackpasswd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
4、增加identity - keystone
登陆mysql，创建数据库
mysql -uroot -proot
>create database keystone;
>GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘localhost‘ IDENTIFIED BY ‘keystone‘;
>GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘%‘ IDENTIFIED BY ‘keystone‘;
说明，创建一个keystone库，并且授权给keystone用户所有权限，密码为keystone
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
vi /etc/keystone/keystone.conf //修改或增加配置如下
[DEFAULT]
admin_token = 123456
verbose = true
[database]
connection = mysql://keystone:keystone@controller/keystone
[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-managedb_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：
[root@controller ~]# mysql -ukeystone -pkeystone -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
配置apache
先编辑配置文件 /etc/httpd/conf/httpd.conf
增加或更改
ServerName controller
编辑配置文件 vi /etc/httpd/conf.d/wsgi-keystone.conf 内容如下

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
[root@controller ~]# openstack project create --domain default --description "Service Project" service +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | Service Project | | domain_id | default | | enabled | True | | id | e01123d140d248bfbbc21aa844453079 | | is_domain | False | | name | service | | parent_id | None | +-------------+----------------------------------+ [root@controller ~]#
创建demo租户

openstack role create user
[root@controller~]# openstack role create user +-------+----------------------------------+ | Field |Value | +-------+----------------------------------+ | id | 2f304e27f0fb401a9425cf4644179fb5 | | name | user | +-------+----------------------------------+ [root@controller~]#
添加user角色到demo租户和demo用户
openstack role add --project demo --user demo user
[root@controller~]# 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
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

启动服务
systemctl enableopenstack-glance-api.service openstack-glance-registry.service
systemctl startopenstack-glance-api.service openstack-glance-registry.service
增加image - 验证操作(controller)
(1) 添加环境变量
echo"export OS_IMAGE_API_VERSION=2" | tee -a admin-openrc.sh demo-openrc.sh
(2) 执行admin-openrc.sh
sourceadmin-openrc.sh
(3) 下载镜像
wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img
[root@controller ~]# wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img --2016-09-21 14:51:01-- http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img Resolving download.cirros-cloud.net (download.cirros-cloud.net)... 64.90.42.85 Connecting to download.cirros-cloud.net (download.cirros-cloud.net)|64.90.42.85|:80... connected.

增加compute - 前期准备(controller
compute又叫nova，是OpenStack中的计算组织控制器。OpenStack中实例（instances）生命周期的所有活动都由Nova处理。这样使得Nova成为一个负责管理计算资源、网络、认证、所需可扩展性的平台。但是，Nova自身并没有提供任何虚拟化能力，相反它使用libvirt API来与被支持的Hypervisors（kvm、xen、vmware等）交互。
创建nova库，并创建nova用户
mysql -uroot -proot
MariaDB [(none)]> create database nova; Query OK, 1 row affected (0.00 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘localhost‘ IDENTIFIED BY ‘nova‘; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘%‘ IDENTIFIED BY ‘nova‘; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> flush privileges; Query OK, 0 rows affected (0.00 sec)

使用如下命令检查你的机器cpu是否支持虚拟化
egrep -c‘(vmx|svm)‘ /proc/cpuinfo
如果得到的数字大于0，说明是支持的，否则说明不支持，若为0，需要编辑配置文件，不等于0就不用编辑配置
vi /etc/nova/nova.conf //编辑
